ABSTRACT:
In order to improve rigidity and stability, shorten a whole length, reduce the number of component parts and assembling steps in an inscribed meshing planetary gear construction, a flange part 114 of an output shaft 102 inner pins 107 and support ring 117 are supported at both ends by bearings 115a and 115b, and then a reduction mechanism part is assembled between bearings 115a and 115b. Axial position of the inner pins 107 are set by inner rings 124a and 124b of the bearings 115a and 115b. Subsequently, with respect to inner pins 107, it is not necessary to provide any shoulder or treading, and the shape is allowed to be simplified, so that machining for high hardness and high accuracy can be realized at low cost, and then a predetermined quality can be secured together with both supporting structures without requiring any expensive inner rollers. This constitution can also be applied in the inscribed meshing planetary gear construction having a carrier pin 116.
