The power is transmitted to a third carrier 33 that supports the gears 28, 29, 30. The output shaft 20A is fixed to the third carrier 33.

ギヤケース２１は、一端側に開口２１Ａを有し、他端側に軸孔２１Ｂを有している。出力軸２０Ａは、軸受４０に軸支され、Ｏリング４１を介して、軸孔２１Ｂから突出しており、軸孔２１Ｂの外側では、ワッシャ４２を介してＥリング４３が係合されることで、抜け止めがなされている。   The gear case 21 has an opening 21A on one end and a shaft hole 21B on the other end. The output shaft 20A is supported by the bearing 40 and protrudes from the shaft hole 21B via the O-ring 41.

ギヤケース２１の開口２１Ａには、フランジ１４の外周が固定される。フランジ１４の外周面は、開口２１Ａ付近で、ギヤケース２１の内面にネジ止め或いは溶接などで固定される。   The outer periphery of the flange 14 is fixed to the opening 21 </ b> A of the gear case 21. The outer peripheral surface of the flange 14 is fixed to the inner surface of the gear case 21 by screwing or welding near the opening 21A.

フランジ１４の外周部には、弾性リング収容部５０が設けられている。弾性リング収容部５０は、角部を切り欠き状にしたフランジ１４の側面とギヤケース２１の開口２１Ａ付近の内面によって囲まれている。この弾性リング収容部５０に、ギヤケース２１内の防塵・防水を得るための弾性リング２が圧入されている。弾性リング２としては、Ｏリング、角リング、Ｘリング、Ｔリング、Ｄリングなどを用いることができる。   An elastic ring housing 50 is provided on the outer periphery of the flange 14. The elastic ring accommodating portion 50 is surrounded by a side surface of the flange 14 having a cut-out corner and an inner surface near the opening 21 </ b> A of the gear case 21. The elastic ring 2 for obtaining dust and water resistance in the gear case 21 is press-fitted into the elastic ring housing 50. As the elastic ring 2, an O ring, a square ring, an X ring, a T ring, a D ring, or the like can be used.

ギヤドモータ１の組み付け工程を説明すると、ギヤ機構部２０側は、開口２１Ａからギヤケース２１内に、Ｏリング４１と軸受４０を順に組み込み、更に、出力軸２０Ａが固定された第３キャリア３３を組み込み、その後は、遊星ギヤ２８，２９，３０、サンギヤ３５がキャリア軸３２Ａに固定された第２キャリア３２、遊星ギヤ２５，２６，２７、サンギヤ３４がキャリア軸３１Ａに固定された第１キャリア３１、遊星ギヤ２２，２３，２４の順に組み込んでいく。   The assembling process of the geared motor 1 will be described. On the side of the gear mechanism section 20, the O-ring 41 and the bearing 40 are sequentially installed in the gear case 21 from the opening 21A, and further, the third carrier 33 to which the output shaft 20A is fixed is installed. Thereafter, the planetary gears 28, 29, 30 and the second carrier 32 with the sun gear 35 fixed to the carrier shaft 32A, the planetary gears 25, 26, 27, the first carrier 31 with the sun gear 34 fixed to the carrier shaft 31A, the planets The gears 22, 23, 24 are assembled in this order.

これに対して、モータ本体１０側は、回転軸１１に駆動ギヤ１３を固定して、端面１２にフランジ１４を固定し、フランジ１４の外周部における弾性リング収容部５０に弾性リング２を挿入する。その後、ギヤケース２１の開口２１Ａに駆動ギヤ１３とフランジ１４を挿入して、開口２１Ａ付近のギヤケース２１をフランジ１４の外周面に溶接などで固定する。   On the other hand, on the side of the motor body 10, the drive gear 13 is fixed to the rotating shaft 11, the flange 14 is fixed to the end face 12, and the elastic ring 2 is inserted into the elastic ring receiving portion 50 on the outer periphery of the flange 14. . Thereafter, the drive gear 13 and the flange 14 are inserted into the opening 21A of the gear case 21, and the gear case 21 near the opening 21A is fixed to the outer peripheral surface of the flange 14 by welding or the like.

図３は、弾性リング収容部５０の断面図を示している。弾性リング収容部５０は、回転軸１１に対して一定角度で傾斜して、モータ本体１０の端面１２に対面する弾性リング圧接面５１を有している。弾性リング圧接面５１は、回転軸１１の周りに軸対称に設けられており、弾性リング収容部５０内に弾性リング２を押し込むと、弾性リング２は、押し潰された状態になり、弾性リング２の弾性反発力で弾性リング圧接面５１を押圧する。   FIG. 3 shows a cross-sectional view of the elastic ring accommodating portion 50. The elastic ring accommodating portion 50 has an elastic ring press contact surface 51 that is inclined at a fixed angle with respect to the rotation shaft 11 and faces the end surface 12 of the motor body 10. The elastic ring press contact surface 51 is provided axially symmetrically around the rotating shaft 11. When the elastic ring 2 is pushed into the elastic ring housing 50, the elastic ring 2 is crushed, The elastic resilient force of 2 presses the elastic ring pressing surface 51.

フランジ１４とギヤケース２１とを固定する前に、図３に示すように弾性リング収容部５０内に弾性リング２を押し込むと、回転軸１１に対して傾斜した弾性リング圧接面５１の反力で、弾性リング２を介してギヤケース２１がモータ本体１０側に引き寄せられることになり、回転軸１１に対してギヤケース２１の姿勢が適正に規制されて、ギヤケース２１の中心軸と回転軸１１の軸合わせがなされることになる。弾性リング２として、Ｏリングを用いることで、モータ本体１０とギヤケース２１に対して均一に圧力を掛けることができる。この状態で、ギヤケース２１をフランジ１４に固定すると、ギヤケース２１内面の固定内歯２１Ｂと回転軸１１に固定されている駆動ギヤ１３の軸合わせが適正になされることになるので、ギヤケース２１内の遊星歯車伝動機構は、片当たりの少ない回転駆動が可能になり、動作音の発生を抑制することができる。   Before the flange 14 and the gear case 21 are fixed, when the elastic ring 2 is pushed into the elastic ring receiving portion 50 as shown in FIG. 3, the reaction force of the elastic ring pressing surface 51 inclined with respect to the rotating shaft 11 causes The gear case 21 is drawn toward the motor main body 10 via the elastic ring 2, and the posture of the gear case 21 with respect to the rotation shaft 11 is appropriately regulated, so that the center axis of the gear case 21 and the rotation shaft 11 are aligned. Will be done. By using an O-ring as the elastic ring 2, pressure can be uniformly applied to the motor body 10 and the gear case 21. In this state, when the gear case 21 is fixed to the flange 14, the fixed internal teeth 21 </ b> B on the inner surface of the gear case 21 and the drive gear 13 fixed to the rotating shaft 11 are properly aligned. The planetary gear transmission mechanism enables a rotational drive with a small amount of contact, thereby suppressing the generation of operation noise.

以上説明したように、本発明の実施形態に係るギヤドモータ１は、フランジ１４とギヤケース２１との間に弾性リング２を介在させることで、ギヤケース２１内の防塵・防水が可能になり、動作音が大きくなる外的な要因を排除することができる。そして、弾性リング２を収容する弾性リング収容部５０において、回転軸１１に対して一定角度で傾斜して、モータ本体１０の端面１２に対面する弾性リング圧接面５１を設けることで、弾性リング２による防塵・防水効果に加えて、ギヤケース２１と駆動ギヤ１３の適正な軸合わせによる動作音低減効果を得ることができる。これによって、動作音が大きくなる機構的な要因も合わせて排除することが可能になる。   As described above, in the geared motor 1 according to the embodiment of the present invention, the elastic ring 2 is interposed between the flange 14 and the gear case 21, so that dustproof and waterproof inside the gear case 21 are possible, and the operation noise is reduced. External factors that increase the size can be eliminated. The elastic ring accommodating portion 50 for accommodating the elastic ring 2 is provided with an elastic ring press contact surface 51 that is inclined at a fixed angle with respect to the rotating shaft 11 and faces the end surface 12 of the motor body 10. In addition to the dustproof / waterproof effect, the operation noise can be reduced by properly aligning the gear case 21 with the drive gear 13. As a result, it is possible to eliminate a mechanical factor that causes the operating sound to increase.

図４は、本発明の実施形態に係るギヤドモータ１の適用例を示している。ギヤドモータ１は、図４（ａ）に示すように、スマートフォンなどの携帯情報端末１００の駆動部（カメラユニットや開閉カバーユニットなど）に組み込むことができ、また、図４（ｂ）に示すように、ロボット２００の関節駆動部などに組み込むことができる。本発明の実施形態に係るギヤドモータ１を備える携帯情報端末１００やロボット２００は、細かい塵や水分が存在する環境下で使用する場合であっても、動作音の少ない静穏な駆動部の動作を実現することができる。   FIG. 4 shows an application example of the geared motor 1 according to the embodiment of the present invention. As shown in FIG. 4A, the geared motor 1 can be incorporated in a driving unit (a camera unit, an opening / closing cover unit, and the like) of the portable information terminal 100 such as a smartphone, and as shown in FIG. , The joint drive unit of the robot 200 or the like. The portable information terminal 100 or the robot 200 including the geared motor 1 according to the embodiment of the present invention realizes a quiet operation of the drive unit with little operation noise even when used in an environment where fine dust and moisture are present. can do.

以上、本発明の実施の形態について図面を参照して詳述してきたが、具体的な構成はこれらの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。なお、前述した例では、弾性リング圧接面５１をフランジ１４側に設けているが、ギヤケース２１の内面側に、回転軸１１に対して一定角度で傾斜して、モータ本体１０の端面に対面する弾性リング圧接面を設けてもよい。   As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and a design change or the like may be made without departing from the scope of the present invention. The present invention is also included in the present invention. In the above-described example, the elastic ring pressure contact surface 51 is provided on the flange 14 side.
