Description
特許文献1に記載の技術では、一対のキャリア体を連結する内ピンが中央の大径部と軸方向両端の小径部とを有しており、小径部の外周面に形成された雄ねじがキャリア体に締結される。そして、大径部から小径部に縮径する段差部分がキャリア体の表面と当接している。この構造では、締結による軸方向の圧縮応力と車重による曲げ応力とが内ピンに作用する。そのため、高い圧縮応力がキャリア体の当接面に作用し、当接面が座屈してしまうするおそれがある。 In the technique described in Patent Document 1, pin inner connecting a pair of carrier body has a small diameter portion of the large diameter portion and both axial ends of the central, external thread formed on the outer peripheral surface of the small diameter portion Fastened to the carrier body. And the level | step-difference part diameter-reduced from a large diameter part to a small diameter part is contact | abutted with the surface of a carrier body. In this structure, axial compressive stress due to fastening and bending stress due to vehicle weight act on the inner pin. Therefore, high compressive stress may act on the contact surface of the carrier body, and the contact surface may be buckled.
図3を参照すると、従来技術に係る減速機10’のキャリアピン42’は、外歯歯車24、26に挿通される大径部42B’と、第1キャリア体34’に挿入される小径部42D’との間に段差部分42C’が形成されており、この段差部分42C’が第1キャリア体34’の反車体側にある座面34B’と当接している。外歯歯車24、26に形成されるキャリアピン孔24B’、26B’の直径は、内ピンと外歯歯車間の伝達トルクを確保するために容易に拡大することはできないため、キャリアピン42’の大径部42B’の直径も制限される。このため、キャリアピン42’と第1キャリア体34’の座面34B’との当接面積が非常に小さくなっている。 Referring to FIG. 3, the small diameter 'carrier pin 42' reducer 10 according to the prior art, 'and, the first carrier member 34' the large diameter portion 42B to be inserted into the external gear 24, 26 is inserted into A stepped portion 42C ′ is formed between the portion 42D ′ and the stepped portion 42C ′ is in contact with the seating surface 34B ′ on the side opposite to the vehicle body of the first carrier body 34 ′. Since the diameters of the carrier pin holes 24B ′ and 26B ′ formed in the external gears 24 and 26 cannot be easily increased in order to secure the transmission torque between the inner pin and the external gear, the carrier pin 42 ′ The diameter of the large diameter portion 42B ′ is also limited. For this reason, the contact area between the carrier pin 42 'and the seating surface 34B' of the first carrier body 34 'is very small.
