PLANETARY GEAR SPEED REDUCER AND MACHINING METHOD FOR PLANETARY SUPPORTING

摘要

The method of processing the planetary gear reducer and the support pin for the planetary gear according to the present invention is to reduce the number of parts, to facilitate the assembly and to reduce the cost, and also to support the support pin so that the vertical part of the support pin with respect to the flange cross section can be easily obtained. Forging is made to be an integral part of the flange cross section. A plurality of support pins having a hollow cylindrical shape are extruded under the same angular pitch on the same circumference on the rear end face of the flange cross section integrally formed with the output rotating shaft. The front end face of the flange cross section has a recess cross section formed coaxially with the support pin. The outer diameter of the support pin is formed smaller than the inner diameter of the recess cross section. The remote end of the support pin is open and the hollow cross section of the support pin communicates with the recess cross section.
