Description

本発明は、内輪が分割された複列転がり軸受に関する。   The present invention relates to a double-row rolling bearing in which an inner ring is divided.

車軸に外嵌された車軸管の外径面に装着され、車輪のハブを回転自在に支持する車輪軸受装置等に使用される複列転がり軸受には、分割された内輪を連結環で連結し、内輪の連結部を密封リングで密封したものがある（例えば、特許文献１参照）。   A double-row rolling bearing used in a wheel bearing device or the like that is mounted on an outer diameter surface of an axle tube that is externally fitted to an axle and that rotatably supports a hub of a wheel has a divided inner ring connected by a connecting ring. In some cases, the inner ring connecting portion is sealed with a sealing ring (see, for example, Patent Document 1).

この種の複列転がり軸受では、例えば、図５に示す複列円錐ころ軸受のように、一体の外輪５１と対向する分割された内輪５２が、内径面に設けられた環状溝５４に装着された連結環５５で連結され、内輪５２の連結部を密封する密封リング５６が、内輪５２の外径面に設けられた環状凹部５７に装着される。   In this type of double-row rolling bearing, for example, as in the double-row tapered roller bearing shown in FIG. 5, a divided inner ring 52 facing the integral outer ring 51 is mounted in an annular groove 54 provided on the inner diameter surface. A sealing ring 56 that is connected by the connecting ring 55 and seals the connecting portion of the inner ring 52 is attached to an annular recess 57 provided on the outer diameter surface of the inner ring 52.

特開２００１−９９１７２号公報JP 2001-99172 A

特許文献１に記載された従来の複列転がり軸受は、連結環が内輪の内径側に装着され、連結部の密封リングが内輪の外径側に装着されているので、例えば、図５に示した複列円錐ころ軸受を組み立てる際には、まず、図６（ａ）に示すように、外輪５１に一方の内輪５２と円錐ころ５３を組み込んだ状態で、この内輪５２の外径面の環状凹部５７に密封リング５６を取り付け、この後、図６（ｂ）に示すように、他方の内輪５２と円錐ころ５３を外輪５１に組み込み、さらに、図６（ｃ）に示すように、内輪５２の内径側を連結環５５で連結する必要がある。このため、組み立て工程が３工程となって手間がかかる問題がある。また、内輪５２の連結部で、連結環５５を装着する環状溝５４と密封リング５６を装着する環状凹部５７とを、内輪５２の内径面と外径面とに別々に設ける必要があり、内輪５２の加工に手間がかかる問題もある。   In the conventional double row rolling bearing described in Patent Document 1, the connecting ring is mounted on the inner diameter side of the inner ring, and the sealing ring of the connecting portion is mounted on the outer diameter side of the inner ring. When assembling the double row tapered roller bearing, first, as shown in FIG. 6A, the inner ring 52 and the tapered roller 53 are incorporated in the outer ring 51, and the outer diameter surface of the inner ring 52 is annular. A sealing ring 56 is attached to the recess 57, and then, as shown in FIG. 6B, the other inner ring 52 and the tapered roller 53 are incorporated in the outer ring 51, and further, as shown in FIG. It is necessary to connect the inner diameter side of each of them with a connecting ring 55. For this reason, there exists a problem which an assembly process becomes a 3 process and takes time. Further, it is necessary to separately provide an annular groove 54 for mounting the connection ring 55 and an annular recess 57 for mounting the sealing ring 56 at the connecting portion of the inner ring 52 on the inner diameter surface and the outer diameter surface of the inner ring 52. There is also a problem that it takes time to process 52.

そこで、本発明の課題は、内輪が分割された複列転がり軸受の組み立てと、分割された内輪の加工を簡素化することである。   Accordingly, an object of the present invention is to simplify the assembly of a double row rolling bearing in which an inner ring is divided and the processing of the divided inner ring.

上記の課題を解決するために、本発明は、一体の外輪と分割された内輪との間に転動体を複列に配列し、前記分割された内輪を内径側に装着される連結環で連結して、内輪の連結部を密封リングで密封した複列転がり軸受において、前記連結環の両側に、中央側に向けて外径側へ立ち上がる複数の切起こしを設け、前記分割された内輪の内径面の連結部の両側に設けた環状溝に、前記切起こしを嵌め込むとともに、前記連結部を密封する密封リングを前記内輪の内径側に装着して、前記連結環で保持する構成を採用した。 In order to solve the above-mentioned problems, the present invention has a structure in which rolling elements are arranged in a double row between an integral outer ring and divided inner rings, and the divided inner rings are connected by a connecting ring mounted on the inner diameter side. In the double-row rolling bearing in which the inner ring connecting portion is sealed with a sealing ring, on both sides of the connecting ring, a plurality of raised parts rising toward the outer diameter side toward the center side are provided, and the inner diameter of the divided inner ring Adopting a configuration in which the cut and raised portions are fitted into annular grooves provided on both sides of the connecting portion of the surface, and a sealing ring for sealing the connecting portion is mounted on the inner diameter side of the inner ring and held by the connecting ring. .

すなわち、連結部を密封する密封リングを内輪の内径側に装着して、連結環で保持することにより、密封リングと連結環を内輪の内径側へ同時に装着可能とするとともに、内輪の連結部での内径面の加工を不要とし、内輪が分割された複列転がり軸受の組み立てと、分割された内輪の加工を簡素化できるようにした。   That is, by attaching a sealing ring for sealing the connecting portion to the inner diameter side of the inner ring and holding it with the connecting ring, the sealing ring and the connecting ring can be simultaneously attached to the inner diameter side of the inner ring. The inner surface of the inner ring is not required to be processed, and the assembly of the double row rolling bearing with the divided inner ring and the machining of the divided inner ring can be simplified.

前記密封リングを前記連結環の外径面に一体に装着することにより、軸受の組み立てをさらに簡素化することができる。   By assembling the sealing ring integrally with the outer diameter surface of the connecting ring, the assembly of the bearing can be further simplified.

上述した各複列転がり軸受は、車軸に外嵌された車軸管の外径面に装着され、車輪のハブを回転自在に支持するものに好適である。   Each of the above-described double row rolling bearings is suitable for a bearing that is mounted on an outer diameter surface of an axle tube that is fitted on an axle and rotatably supports a wheel hub.

本発明の複列転がり軸受は、連結部を密封する密封リングを内輪の内径側に装着して、連結環で保持するようにしたので、密封リングと連結環を内輪の内径側へ同時に装着可能とするとともに、内輪の連結部での内径面の加工を不要とし、内輪が分割された複列転がり軸受の組み立てと、分割された内輪の加工を簡素化することができる。   In the double row rolling bearing of the present invention, the sealing ring for sealing the connecting portion is mounted on the inner diameter side of the inner ring and is held by the connecting ring, so the sealing ring and the connecting ring can be simultaneously mounted on the inner diameter side of the inner ring. In addition, it is not necessary to process the inner diameter surface at the connecting portion of the inner ring, and the assembly of the double row rolling bearing in which the inner ring is divided and the machining of the divided inner ring can be simplified.

前記密封リングを連結環の外径面に一体に装着することにより、軸受の組み立てをさらに簡素化することができる。   By assembling the sealing ring integrally with the outer diameter surface of the connecting ring, the assembly of the bearing can be further simplified.
