Title:
OUTER CYCLOID PLANETARY GEAR CAM OF CYCLOID TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2017015229
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an outer cycloid planetary gear cam of a cycloid transmission device capable of converting a rotational motion of a driving shaft into a linear motion of an output device and outputting it.SOLUTION: In this invention, an outer cycloid planetary gear is arranged in an inner fixed ring gear of a fixed housing. An eccentric ring driving shaft is connected to the prescribed driving shaft and at the same time it is freely rotated in an eccentric ring fixing hole of the outer cycloid planetary gear. When the driving shaft is rotated, the eccentric ring driving shaft is rotated in cooperation with the outer cycloid planetary gear in the inner fixed ring gear. The outer cycloid planetary gear has a cam track on it and both a cam follower pin connected to the output device and a follower roller ball are arranged on the cam track. When the outer cycloid planetary gear is rotated, the prescribed cam follower pin is moved up and down due to variation of a depth of a recessed part of the cam track, thereby it is connected to the output device to cause the output device to be moved.SELECTED DRAWING: Figure 1
