Description
ケーシング12の内側には、2個のボールベアリング21,21を介して、中空筒状の入力軸14aが、内歯歯車11の軸線と同軸で、第1キャリア部材13a及び第2キャリア部材13bに回転可能に軸支されている。入力軸14aにおいて、ボールベアリング21,21の間には、外径及び偏心量δ1が互いに等しく、偏心方向が互いに180度異なる位相となる一対の偏心部22,22が隣接して形成されている。各偏心部22,22には、全周に亘って配設される横断面円形状の複数のころ23,23・・からなるニードルベアリング24が設けられて、ニードルベアリング24を介して、外歯歯車10,10がそれぞれ回転可能に外装されている。入力軸14aにおける軸方向の入力側の端面には、複数のボルト孔が形成されている。入力軸14aにおける軸方向の出力側の端面位置は、出力側のボールベアリング21における出力側の端面位置と、略同一の位置になっている。 Inside the casing 12, a hollow tubular input shaft 14a is coaxial with the axis of the internal gear 11 and is attached to the first carrier member 13a and the second carrier member 13b via two ball bearings 21 and 21. It is rotatably supported. In the input shaft 14a, a pair of eccentric portions 22, 22 having an outer diameter and an eccentricity δ1 equal to each other and having phases different from each other by 180 degrees are formed adjacent to each other between the ball bearings 21 and 21. .. Each of the eccentric portions 22, 22 is provided with a needle bearing 24 composed of a plurality of rollers 23, 23 ... The gears 10 and 10 are rotatably exteriorized, respectively. A plurality of bolt holes are formed on the end face of the input shaft 14a on the input side in the axial direction. The position of the end face on the output side in the axial direction of the input shaft 14a is substantially the same as the position of the end face on the output side of the ball bearing 21 on the output side.
また、第1減速機である直交軸減速機100と第2減速機である平行軸減速機200とでオイルシールの位置が同じであるため、出力部の形状が同じとなる。このため、同じ出力部の形状の減速機シリーズを提供することができる。 Further, since the position of the oil seal is the same between the orthogonal axis reducer 100 which is the first reducer and the parallel axis reducer 200 which is the second reducer, the shape of the output portion is the same. Therefore, it is possible to provide a speed reducer series having the same output unit shape.
