Description

本発明は、軸受装置及び軸受装置の製造方法に関し、例えば、トランスミッションにおけるギヤなどの回転支持部に用いられる軸受装置及び軸受装置の製造方法に関する。   The present invention relates to a bearing device and a manufacturing method of the bearing device, and for example, relates to a bearing device used for a rotation support portion such as a gear in a transmission and a manufacturing method of the bearing device.

従来のこの種の軸受装置としては、例えば、図18に示すように、内輪101と外輪102との間に複数の転動体103が配設された転がり軸受104と、該転がり軸受104の外輪102の軸方向端面に当接して転がり軸受104をハウジングHに固定する固定プレート105と、を備えるものが知られている(特許文献1参照)。   As a conventional bearing device of this type, for example, as shown in FIG. 18, a rolling bearing 104 in which a plurality of rolling elements 103 are disposed between an inner ring 101 and an outer ring 102, and an outer ring 102 of the rolling bearing 104. And a fixed plate 105 that abuts against the axial end surface of the roller bearing 104 and fixes the rolling bearing 104 to the housing H (see Patent Document 1).

また、自動車の小型化と共にトランスミッションの小型化が要請されており、このような要請に応える軸受装置として、図19に示すように、転がり軸受104の外輪102の外周面の軸方向端部に小径段部106を設け、該小径段部106に固定プレート107の円形穴部110を嵌合固定したものが知られている。また、固定プレート107は、その円形穴部110の周縁部分の肉を潰し加工により径方向内側に突出させ、係止部108を形成し、小径段部106に形成された係止溝109に係止させている(特許文献2参照)。   Further, there is a demand for downsizing of a transmission along with downsizing of an automobile. As a bearing device that meets such a demand, as shown in FIG. 19, a small diameter is provided at an axial end of an outer peripheral surface of an outer ring 102 of a rolling bearing 104. A stepped portion 106 is provided, and a circular hole 110 of a fixing plate 107 is fitted and fixed to the small diameter stepped portion 106. Further, the fixing plate 107 squeezes the peripheral portion of the circular hole portion 110 so as to project radially inwardly to form a locking portion 108, and engages with a locking groove 109 formed in the small-diameter step portion 106. (See Patent Document 2).

従来、このような固定プレート107と軸受104とを結合させる方法として、固定プレートの円形穴部の周縁部分を潰し加工により径方向内側に突出させ、係止部を小径段部に形成された係止溝に係止させること及び係止部が小径段部を乗り越えて係止溝に係止させることが種々考案されており(例えば、特許文献1〜8参照)、また、外輪102の外周面の軸方向端部に小径段部106に切り欠きを設けることが知られている(特許文献9参照)。   Conventionally, as a method for coupling the fixed plate 107 and the bearing 104, a peripheral portion of the circular hole portion of the fixed plate is projected inward in the radial direction by crushing, and the engaging portion is formed in a small-diameter stepped portion. Various methods have been devised for engaging the retaining groove and for engaging the retaining portion over the small-diameter step portion (see, for example, Patent Documents 1 to 8), and the outer peripheral surface of the outer ring 102. It is known that a notch is provided in the small-diameter step portion 106 at the end portion in the axial direction (see Patent Document 9).

ところで、従来、バレ止め用突起の潰し加工は、特許文献3のように、加工工程も少なく、低コスト思想としては非常に優れている。しかし、そのシンプルさゆえの弊害として、パンチ精度・部品精度が複数突起の出張量(内接円形)の制御に影響、また突起自体の形状も潰す肉の量で変わるなど、軸受との組み付け性及び干渉の観点で制御が大変難しい。特許文献7の手法においても、組み付け時に外に突起が逃げ切ってしまうため、軸受組み付け後、外側に塑性変形して突起が戻ってこなくなり、非分離の機能を果たせなくなる可能性が高い。   By the way, conventionally, the crushing process of the anti-barre projection has few processing steps as in Patent Document 3, and is very excellent as a low cost idea. However, because of its simplicity, punch accuracy and component accuracy affect the control of the travel amount of multiple projections (inscribed circle), and the shape of the projection itself changes depending on the amount of meat to be crushed. Control is very difficult from the viewpoint of interference. Even in the method of Patent Document 7, since the protrusions escape to the outside at the time of assembling, there is a high possibility that after the bearing is assembled, the protrusions are plastically deformed to the outside and the protrusions do not return to perform the non-separating function.

また、特許文献8では、1回目のプレスで外輪の掛かり部を乗り越え、出っ張り部を除去加工した後、2回目のプレスで突起を設けるという案もあるが、これも突起自体潰し加工による成形であるがゆえに突起形状の安定化は容易ではない。   Further, in Patent Document 8, there is a proposal that a protrusion is provided by the second press after overhanging the outer ring hanging portion by the first press and removing the protruding portion, but this is also formed by crushing the protrusion itself. Therefore, stabilization of the protrusion shape is not easy.

ここで、軌道輪と固定プレートは組み立ての便宜上、互いに相対回転を許容せねばならず、干渉による相対回転不良は大きな不具合要因であった。固定プレートでの形状制御が難しいならば、軌道輪の組み付け部形状で逃げてあげればよいという考えに到達するが、軌道輪においてもそもそもの根幹の機能として転動面の剛性のほうが組み立て性よりもはるかに重要度が高く、必然的に、固定プレートとの組み付け面形状は余ったスペースに形成されるという制限が生まれる。   Here, for the convenience of assembly, the race ring and the fixed plate must be allowed to rotate relative to each other, and the relative rotation failure due to interference was a major cause of failure. If it is difficult to control the shape with the fixed plate, the idea is to escape with the shape of the assembly part of the race ring. However, it is much more important, and inevitably there is a restriction that the shape of the assembly surface with the fixed plate is formed in an extra space.

本発明は、上記の課題を鑑み、その目的は、部品点数は上記同様極限まで抑え、突起部形状の安定成形且つ軌道輪との干渉を避け相対回転可能な軸受装置及び軸受装置の製造方法を提供するものである。   In view of the above problems, the present invention aims to provide a bearing device and a manufacturing method of the bearing device capable of suppressing the number of parts to the limit as described above, stably forming the protrusion shape, and avoiding interference with the raceway and relatively rotating. It is to provide.

本実施形態の軸受装置10は、例えば、トランスミッションにおけるギヤなどの回転支持部に用いられる軸受装置として使用され、従来構造の図18及び図19も参照して、内輪101と外輪102との間に複数の転動体103が配設された転がり軸受104と、該転がり軸受104をハウジングHに固定すべく、転がり軸受104の外輪102の外周面に嵌合される円形穴部13を有する固定プレート11と、を備える。なお、本発明は、固定プレート11の構成が従来構造と主に異なるため、以下の説明では、固定プレート11と、該固定プレートが取り付けられる転がり軸受104の外輪102とを中心に説明する。
(First embodiment)
1 is a perspective view of a bearing device according to a first embodiment of the present invention, FIG. 2 is a central longitudinal sectional view of the bearing device of FIG. 1, and FIG. 3 (a) is a section III of FIG. FIG. 3B is an enlarged cross-sectional view of FIG. 3B, and FIG. 4 is a perspective view of a fixed plate of the bearing device.
The bearing device 10 of the present embodiment is used as, for example, a bearing device used for a rotation support portion such as a gear in a transmission, and also between the inner ring 101 and the outer ring 102 with reference to FIGS. 18 and 19 of the conventional structure. A rolling plate 104 provided with a plurality of rolling elements 103, and a fixing plate 11 having a circular hole 13 fitted to the outer peripheral surface of the outer ring 102 of the rolling bearing 104 in order to fix the rolling bearing 104 to the housing H. And comprising. In the present invention, since the configuration of the fixed plate 11 is mainly different from the conventional structure, the following description will focus on the fixed plate 11 and the outer ring 102 of the rolling bearing 104 to which the fixed plate is attached.

図1及び図2に示すように、外輪102の軸方向の端部外周部には、固定プレート11が嵌合される小径段部106が形成されており、該小径段部106の外周面の軸方向内側寄りには、係止溝109が周方向全周に沿って形成されている。   As shown in FIGS. 1 and 2, a small-diameter step portion 106 into which the fixing plate 11 is fitted is formed on the outer peripheral portion of the outer ring 102 in the axial direction, and the outer peripheral surface of the small-diameter step portion 106 is formed. On the inner side in the axial direction, a locking groove 109 is formed along the entire circumference in the circumferential direction.

一方、固定プレート11は、図4に示すように、中央に円形穴部13を有すると共に、外形が略三角形のフランジ状をなしており、三角形状の3つの頂点側にはボルト(不図示)の挿通穴19が形成されている。   On the other hand, as shown in FIG. 4, the fixing plate 11 has a circular hole 13 at the center and has a substantially triangular flange shape, and bolts (not shown) are provided on the three apex sides of the triangular shape. The insertion hole 19 is formed.

また、図2〜図4に示すように、固定プレート11の円形穴部13の内周部には、外輪102の小径段部106に形成された係止溝109に係止される係止部16が径方向内側に突出して形成されている。この係止部16は、本実施形態では、円周方向に略等間隔で3箇所形成されており、それら3箇所の係止部16は、固定プレート11の三角形状の3つの頂点側にそれぞれ配置されている。また、円形穴部13の内周面には、係止部16が形成される円周方向位置の円周方向両側に亘って、凹部20が形成されている。   As shown in FIGS. 2 to 4, on the inner peripheral portion of the circular hole portion 13 of the fixing plate 11, a locking portion that is locked to a locking groove 109 formed in the small diameter step portion 106 of the outer ring 102. 16 is formed projecting radially inward. In the present embodiment, the locking portions 16 are formed at three locations at substantially equal intervals in the circumferential direction, and the locking portions 16 at the three locations are respectively provided on the three apexes of the triangular shape of the fixed plate 11. Has been placed. Moreover, the recessed part 20 is formed in the inner peripheral surface of the circular hole part 13 over the circumferential direction both sides of the circumferential direction position in which the latching | locking part 16 is formed.

係止部16の欠けや軸受に対する固定プレート11の中心度の確保の理由から、固定プレート11の外輪102に対する径方向案内は係止部16で案内するよりも、小径段部106の軸方向内側の平面部D、軸方向外側の平面部Eで案内した方が良い。このため、3つの係止部16と係止溝109との各径方向すきまをAとし、平面部Eにおける固定プレート11の円形穴部13の内周面と小径段部106の外周面106aとの径方向すきまB、平面部Dにおける固定プレート11の円形穴部13の内周面と小径段部106の外周面106aとの径方向すきまをCとすると、その場合のすきま設定は、「すきまA>すきまB、すきまA>すきまC」となる。
平面部D、平面部Eにおいては、基本的にどちらで案内しても構わない。しかし、例えば外輪102の掛かり径(外径)が、径方向内側か径方向外側で同径という前提のもと、固定プレート11をプレス加工する上では「すきまB>すきまC、又は、すきまB=すきまC」となり、径方向内側に段差がないタイプの軌道輪形状であれば、「すきまA>すきまB」だけでよい。
For securing the center of the fixed plate 11 with respect to the chipping of the locking portion 16 and the bearing, the radial guide to the outer ring 102 of the fixed plate 11 is more inward in the axial direction of the small diameter step portion 106 than the locking portion 16. It is better to guide by the flat surface portion D and the flat surface portion E outside in the axial direction . Therefore, each radial clearance between the three locking portions 16 and the locking groove 109 is A, and the inner peripheral surface of the circular hole portion 13 of the fixed plate 11 and the outer peripheral surface 106a of the small-diameter step portion 106 in the plane portion E when radial clearance B of the radial gap between the outer peripheral surface 106a of the inner peripheral surface of the circular hole 13 of the fixing plate 11 in the flat portion D and the cylindrical portion 106 is C, clearances set in that case, “Clearance A> Gap B, Clearance A> Clearance C”.
In the plane part D and the plane part E, you may guide by whichever fundamentally. However, for example, takes the diameter of the outer ring 102 (outer diameter), on the assumption that the same diameter radially inside or radially outside, "clearance B> clearance C is a fixed plate 11 in order to press working, or the gap B = Clearance C ”, and if the shape of the raceway is a type having no step on the radially inner side, only“ clearance A> clearance B ”is required.

図5(a)〜(e)は、本発明に係る軸受装置の固定プレート11の内周部に係止部16を形成する工程を説明する図である。   FIGS. 5A to 5E are views for explaining a process of forming the locking portion 16 on the inner peripheral portion of the fixed plate 11 of the bearing device according to the present invention.

図5(a)に示すように、第1工程では、固定プレート11に、後工程に控える段差成形に備えて、肉逃し用の予備穴14をあける。   As shown in FIG. 5A, in the first step, a spare hole 14 for escaping meat is made in the fixed plate 11 in preparation for the step forming to be kept in the subsequent step.

図5(b)に示すように、第2工程では、第1工程で加工された固定プレート11に、係止部16が形成される径方向位置まで潰し加工する。   As shown in FIG. 5B, in the second step, the fixing plate 11 processed in the first step is crushed to a radial position where the locking portion 16 is formed.

図5(c)、(d)に示すように、第3工程では、第2工程で加工された固定プレート11に、係止部16の形成のための打ち抜き加工をする。ここで、打ち抜き方向は、固定プレート11の軸方向外側面から軸方向に向かって、すなわち、図5(c)では手前から奥に向かって、打ち抜いたほうが良く、打ち抜いた後は、図5(d)のように円形穴部13の内周面と係止部16が成形される。なお、図5(d)に示すように、打ち抜き加工した際には、係止部16には、せん断面17と破断面18が形成されるが、後の平面研磨で寸法精度の良いせん断面17を残し、破断面18は除去される。また、破断面18が残っていても、破断面18はテーパー状となるため、外輪102への圧入の折に、固定プレート11の位置をある程度安定させる効果が期待できる。   As shown in FIGS. 5C and 5D, in the third step, the fixing plate 11 processed in the second step is punched to form the locking portion 16. Here, the punching direction is preferably punched from the outer surface in the axial direction of the fixed plate 11 toward the axial direction, that is, from the front to the back in FIG. 5 (c). As shown in d), the inner peripheral surface of the circular hole 13 and the locking portion 16 are formed. As shown in FIG. 5D, when the punching process is performed, a shearing surface 17 and a fracture surface 18 are formed in the locking portion 16, but a shearing surface with good dimensional accuracy by subsequent planar polishing. 17 and the fracture surface 18 is removed. Even if the fracture surface 18 remains, since the fracture surface 18 is tapered, the effect of stabilizing the position of the fixed plate 11 to some extent can be expected when the outer ring 102 is press-fitted.

図5(e)に示すように、第4工程では、第3工程で加工された固定プレート11に、固定プレート11の軸方向内側面、すなわち図5(e)では手前側から、係止部16の周辺を、たとえば平面研削などで、除去加工する。この除去加工は、固定プレート11の軸方向の真ん中付近に係止部16を形成した場合や、係止部16の剛性を下げたい場合、また、外輪102の軌道面が変形するのを抑制するための接触点緩和などの目的で行なわれる。なお、この除去加工により形成される凹部20がプレス成形でつくれる場合は、第2工程時に同時加工、または第2工程と第3工程の間で行なえば良い。   As shown in FIG. 5E, in the fourth step, the fixing plate 11 processed in the third step is moved from the axially inner side surface of the fixing plate 11, that is, from the front side in FIG. The periphery of 16 is removed by surface grinding, for example. This removal process suppresses the deformation of the raceway surface of the outer ring 102 when the locking portion 16 is formed near the center of the fixing plate 11 in the axial direction, when the rigidity of the locking portion 16 is to be lowered. This is done for the purpose of relaxing the contact point. In addition, when the recessed part 20 formed by this removal process can be made by press molding, it may be performed simultaneously in the second step or between the second step and the third step.

なお、図5(a)〜図5(e)を用いて説明した工程は、固定プレート11を製造するための説明であるため、固定プレート11のボス部や外郭については、説明を分かり易くするため予め完成形状イメージで示しており、実際の製造では、ボス成形や外郭の打ち抜き加工は内径形状成形工程の前後あるいはその中間など、精度を確保する上で必要と思われるタイミングで施されればよく、内径以外の成形工程タイミングは限定されない。
そして、このように構成された固定プレート11は、従来にないプレス加工を用いて係止部16が形成されるため、安価に、安定的且つ高い精度で、係止部16の突起形状を成形することができるばかりでなく、第2工程の潰し加工で潰す量の調整と、第4工程の除去加工で除去する量の調整とを組み合わせれば、係止部16の軸方向で形成される位置も軸方向両側から制御することができる。
Note that the steps described with reference to FIGS. 5A to 5E are descriptions for manufacturing the fixed plate 11, and therefore the bosses and the outline of the fixed plate 11 are easy to understand. Therefore, it is shown in the completed shape image in advance, and in actual manufacturing, if boss molding or outer punching processing is performed at the timing considered necessary to ensure accuracy, such as before and after the inner diameter shape molding process, or in the middle Well, the molding process timing other than the inner diameter is not limited.
The fixing plate 11 configured in this manner is formed with a locking portion 16 using unprecedented press processing, so that the protruding shape of the locking portion 16 can be formed inexpensively, stably and with high accuracy. If the adjustment of the amount to be crushed in the crushing process in the second step and the adjustment of the amount to be removed in the removal process in the fourth step are combined, the locking portion 16 is formed in the axial direction. The position can also be controlled from both axial sides.

このように構成された固定プレート11は、係止部16を外輪102の軸方向の端部から係止溝109までの外周面を弾性変形しながら乗り越えさせ、係止溝109に係止させ、固定プレート11の円形穴部13を外輪102の外周面に嵌合させる。   The fixed plate 11 configured in this manner allows the locking portion 16 to get over the outer peripheral surface from the axial end of the outer ring 102 to the locking groove 109 while elastically deforming, and locks the locking portion 109 to the locking groove 109. The circular hole 13 of the fixed plate 11 is fitted to the outer peripheral surface of the outer ring 102.

以上説明したように、本実施形態の軸受装置10によれば、外輪102の軸方向の端部外周部には、固定プレート11が嵌合される小径段部106が設けられるとともに、該小径段部106の外周面に円周方向に延びる係止溝109が形成され、固定プレート11の円形穴部13には、径方向内側にそれぞれ突出し、プレス打ち抜き工程を用いて成形される複数の係止部16が設けられ、係止部16が、外輪102の軸方向の端部から係止溝109までの外周面を、弾性変形又は塑性変形しながら乗り越えて、係止溝109に係止される。これにより、固定プレート11の係止部16を安価に、安定して、精度良く成形することができ、軸受装置10の組立作業の効率を高めることができ、生産性の向上を図ることができる。   As described above, according to the bearing device 10 of the present embodiment, the outer diameter of the outer ring 102 is provided with the small-diameter step portion 106 to which the fixing plate 11 is fitted, and the small-diameter step portion. A locking groove 109 extending in the circumferential direction is formed on the outer peripheral surface of the portion 106, and a plurality of locking holes protruding inward in the radial direction in the circular hole portion 13 of the fixed plate 11 and formed using a press punching process. A portion 16 is provided, and the locking portion 16 gets over the outer peripheral surface from the axial end of the outer ring 102 to the locking groove 109 while being elastically deformed or plastically deformed, and is locked to the locking groove 109. . Thereby, the latching | locking part 16 of the fixed plate 11 can be shape | molded cheaply, stably and accurately, the efficiency of the assembly operation | work of the bearing apparatus 10 can be improved, and productivity can be aimed at. .

なお、上記実施形態では、凹部20の軸方向側面は、径方向に沿って形成されているが、図6に示す第1変形例のように、凹部20の軸方向側面が径方向に対して傾斜して形成されてもよい。なお、テーパ面の傾斜角度は、外輪102の小径段部106の外周面106aの縁部106bにおける面取り角度と同じくすることが、組立性の観点から好ましい。   In the above embodiment, the axial side surface of the recess 20 is formed along the radial direction. However, as in the first modification shown in FIG. It may be formed to be inclined. Note that the inclination angle of the tapered surface is preferably the same as the chamfering angle at the edge 106b of the outer peripheral surface 106a of the small-diameter stepped portion 106 of the outer ring 102 from the viewpoint of assembling.

また、上記実施形態では、係止部16は、弾性変形により小径段部106の外周面を乗り越えて、径方向に延出して係止溝109内に配置されているが、図7(a)や図8(a)に示すように、折れ曲がった形状で係止溝109内に配置されてもよい。   Moreover, in the said embodiment, although the latching | locking part 16 overcame the outer peripheral surface of the small diameter step part 106 by elastic deformation, it extends to radial direction and is arrange | positioned in the latching groove | channel 109, FIG. Or as shown to Fig.8 (a), you may arrange | position in the latching groove | channel 109 in the bent shape.

また、図1〜5に示す上記実施形態では、係止部が弾性変形して係止溝に係合する場合について説明したが、塑性変形により折り曲げさせながら組み込むようにしてもよい。
即ち、本発明において、固定プレート11を外輪102の小径段部106に組み込む方法としては、以下の(A−1)、(A−2)、(B−1)、(B−2)、のパターンがあり、係止部16の各種形状と、適宜、組み合わせて組み込みを行なうことができる。
(A−1):組付ける前に予め係止部16を組み込み易い形に傾斜して形成しておき、弾性変形で組み込む(パチン挿入)。
(A−2):組付ける前に予め係止部16を組み込み易い形に傾斜して形成しておき、塑性変形(折り曲げ)させながら組み込む。
(B−1):打ち抜き加工したときの形状のまま、軌道輪の掛かり径を乗り越える方法で、弾性変形で組み込む。
(B−2):打ち抜き加工したときの形状のまま、軌道輪の掛かり径を乗り越える方法で、塑性変形(折り曲げ)させながら組み込む。
In the above-described embodiment shown in FIGS. 1 to 5, the case where the locking portion is elastically deformed and engages with the locking groove has been described, but it may be incorporated while being bent by plastic deformation.
That is, in the present invention, the following (A-1), (A-2), (B-1), and (B-2) are methods for incorporating the fixed plate 11 into the small diameter step portion 106 of the outer ring 102. There is a pattern, and it can be incorporated in combination with various shapes of the locking portion 16 as appropriate.
(A-1): Before assembling, the locking portion 16 is inclined in advance so as to be easily assembled, and incorporated by elastic deformation (pachin insertion).
(A-2): Before assembling, the locking portion 16 is inclined in advance so as to be easily assembled and assembled while being plastically deformed (bent).
(B-1): Incorporating by elastic deformation by a method that overcomes the contact diameter of the raceway with the shape when punched.
(B-2): Incorporate while deforming plastically (bending) by the method of getting over the contact diameter of the raceway ring with the shape when punched.

例えば、図7に示す第2変形例においては、図7(b)に示すような径方向に延出する係止部16を、上記(B−2)のように、小径段部106の外周面106aを乗り越える際に塑性変形させて係止溝109に組み込んでもよい。或いは、図7(c)に示すような予め傾斜した係止部16を、上記(A−1)のように、小径段部106の外周面106aを乗り越える際に弾性変形させて係止溝109に組み込んでもよい。   For example, in the second modified example shown in FIG. 7, the locking portion 16 extending in the radial direction as shown in FIG. 7B is used as the outer periphery of the small-diameter stepped portion 106 as shown in (B-2) above. When climbing over the surface 106a, it may be plastically deformed and incorporated into the locking groove 109. Alternatively, the locking portion 16 inclined in advance as shown in FIG. 7C is elastically deformed when getting over the outer peripheral surface 106a of the small-diameter stepped portion 106, as in (A-1), and the locking groove 109 is obtained. It may be incorporated into.

また、図8に示す第3変形例においては、図8(b)に示すような傾斜した係止部16を、上記(A−2)のように、小径段部106の外周面106aを乗り越える際に塑性変形させて係止溝109に組み込んでもよい。或いは、図8(c)に示すような軸方向まで折り曲げた係止部16を、上記(A−1)のように、小径段部106の外周面106aを乗り越える際に弾性変形させて係止溝109に組み込んでもよい。   Further, in the third modification shown in FIG. 8, the inclined locking portion 16 as shown in FIG. 8 (b) gets over the outer peripheral surface 106a of the small-diameter step portion 106 as described above (A-2). At this time, the retaining groove 109 may be plastically deformed. Alternatively, the locking portion 16 bent in the axial direction as shown in FIG. 8 (c) is elastically deformed when the outer peripheral surface 106a of the small-diameter step portion 106 is moved over as in (A-1). It may be incorporated in the groove 109.

また、図9に示す第4変形例のように、固定プレート11の凹部20は、上記実施形態に比べて浅く形成され、係止部16は軸方向内側面寄りに形成されてもよい。   Further, as in the fourth modified example shown in FIG. 9, the concave portion 20 of the fixed plate 11 may be formed shallower than in the above embodiment, and the locking portion 16 may be formed closer to the inner surface in the axial direction.

さらに、図10及び図11に示す第5変形例のように、第4変形例のような固定プレート11が用いられた場合には、係止溝109は、小径段部106の軸方向端面まで形成されればよい。この変形例においても、3つの係止部16と係止溝109との各径方向すきまをAとし、固定プレート11の円形穴部13の内周面と小径段部106の外周面106aとの径方向すきまをBとすると、A>Bを満たすように形成されている。   Further, as in the fifth modification shown in FIGS. 10 and 11, when the fixing plate 11 as in the fourth modification is used, the locking groove 109 extends to the end surface in the axial direction of the small diameter step portion 106. It may be formed. Also in this modification, the radial clearances between the three locking portions 16 and the locking grooves 109 are A, and the inner peripheral surface of the circular hole portion 13 of the fixing plate 11 and the outer peripheral surface 106a of the small-diameter step portion 106. When the radial clearance is B, the gap is formed so as to satisfy A> B.

また、図12に示す第6変形例のように、固定プレート11は凹部20を設けずに固定プレート11と係止部16とが面一となるように形成されてもよい。この固定プレート11も、外輪102の係止溝109の軸方向内側寄りに段部がない場合に適用される。   Further, as in the sixth modification shown in FIG. 12, the fixing plate 11 may be formed so that the fixing plate 11 and the locking portion 16 are flush with each other without providing the recess 20. This fixing plate 11 is also applied when there is no step portion on the inner side in the axial direction of the locking groove 109 of the outer ring 102.

In addition, the shape of the latching | locking part 16 shown in FIG.14 (d) is an example, and is not limited to the shape.

この第2実施形態のように、固定プレート11の内周面を構成する薄肉部21と、係止部16とを同時に形成することで、内周面と係止部16との同心度を向上することができ、組立精度をさらに向上することができる。
なお、その他の構成及び作用については、第1実施形態と同様である。
As in the second embodiment, the concentricity between the inner peripheral surface and the locking portion 16 is improved by forming the thin portion 21 constituting the inner peripheral surface of the fixed plate 11 and the locking portion 16 at the same time. As a result, the assembly accuracy can be further improved.

FIG. 15A is a front view of FIG. 15A, and FIG. 15D is an enlarged view of the IX portion of FIG. 15C.
In the present embodiment, the notch 12 is formed in a substantially fan shape when viewed from the axial direction on at least one position in the circumferential direction in phase with the locking portion 16 on the outer peripheral surface near the end of the small diameter step portion 106 of the outer ring 102. Has been.
As described above, when the outer ring 102 and the fixed plate 11 are assembled, the phases of the notch 12 and the locking portion 16 can be matched more smoothly.
If the locking portion 16 is incorporated from the notch 12 on the outer peripheral surface near the end of the small-diameter step portion 106 of the outer ring 102, the notch 12 is not only used when elastically deformed but also when incorporated plastically. Compared with incorporating from the outer peripheral surface having no twelve, the amount of plastic is less, and a stronger holding effect can be obtained.

外輪102と固定プレート11の一般的な組み込み方法として、たとえば、図15(c)に見えるように、3個の切り欠き12を設けた外輪102に、該切り欠き12と円周方向同位相に3個の係止部16が設けられた固定プレート11を組み込む方法が挙げられる。
