Title:
FLEX SPLINE FOR STRAIN WAVE GEAR DEVICE, AND STRAIN WAVE GEAR DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/169060
Kind Code:
A1
Abstract:
Provided is a flex spline having a novel structure, with which the intended rotational output can be obtained with superior durability and reliability, and the direction in which the rotational output is extracted can be selected with a greater degree of freedom. Also provided is a strain wave gear device using this flex spline. In this flex spline 12 for a strain wave gear device 10, a cylindrical part 40 equipped with external teeth is formed by multiple pin members 18 adjacent to each other in the circumferential direction. The periphery of the cylindrical part 40 is partially pressed and expanded toward the outer circumference by a wave generator 16 and the pin members 18 engage internal teeth 44 of a circular spline 14, and at another portion of the periphery of the cylindrical part 40 the pin members 18 are retained by a retaining means 42 without engaging the internal teeth 44 of the circular spline 14. In addition, an output member 66 or a securing member 64 is attached to a first pin support member 20 and/or a second pin support member 22 supporting both ends of the pin members 18.
