Title:
WAVE GEAR DEVICE HAVING UNIT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/087316
Kind Code:
A1
Abstract:
A cup-type wave gear device (20) having a unit structure and having: a stationary-side member comprising a unit housing (22) and an internal gear (23); a driving-side member comprising an output member (25) and an external gear (26); and a sliding bearing (28) supporting the interval between the stationary-side member and the driving-side member from the radial direction and the thrust direction in a state in which relative rotation is possible. The sliding bearing (28) comprises a cylindrical bushing (28a) mounted in a radial gap, and annular bushings (28b, 28c) mounted respectively in thrust gaps. Thus, it is possible to provide an advantageous wave gear device having a unit structure that is more lightweight and compact than when a rolling bearing is used.
