Title:
WAVE SPEED REDUCER HAVING SELF-LOCKING FUNCTION AND COMPOSITE TYPE REDUCER DEVICE
Document Type and Number:
Japanese Patent JP2017020643
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wave speed reducer having self-locking function and a composite type speed reducer device.SOLUTION: A wave speed reducer having a self-locking function includes a mechanism for outputting and rotating a bearing or a socket wheel at a specific reduction ratio by driving a roller by a cam. A convex arc of the cam is designed to have a self-locking function restricting reverse rotation of the roller. A composite type speed reducer having a multi-stage speed reducing function and formed by combining the wave speed reducer and a planetary gear set, is further included. Thus, this invention solves a problem in a conventional speed reducer that transmission accuracy is not excellent at a small rotation angle, as the self-locking function is not provided.SELECTED DRAWING: Figure 4
