FLEX SPLINE FOR STRAIN WAVE GEAR DEVICE, AND STRAIN WAVE GEAR DEVICE USING SAME

摘要

Provided is a flex spline and a strain wave gear device using this flex spline. In this flex spline for a strain wave gear device, a cylindrical part equipped with external teeth is formed by multiple pin members adjacent to each other in the circumferential direction. The periphery of the cylindrical part is partially pressed and expanded toward the outer circumference by a wave generator and the pin members engage internal teeth of a circular spline, and at another portion of the periphery of the cylindrical part the pin members are retained by a retaining device without engaging the internal teeth of the circular spline. In addition, an output member or a securing member is attached to a first pin support member and/or a second pin support member supporting both ends of the pin members.
