ABSTRACT:
A wave gear drive (1) has first and second end plates (2) and (3) arranged to rotate relative with each other by means of a cross roller bearing (4) positioned between the plates (2, 3). An inner race (41) of the cross roller bearing (4) is formed integrally on a circumferential Inner surface with an internal gear (11). The inner race (41) is directly fastened to the first end plate (2), while an outer race (44) of the cross roller bearing (4) is fastened to the second end plate in a manner such that a circular boss (17) of a flexible external gear is held between the outer race (44) and the second end plate (3). The internal teeth (11) are positioned approximately at a radially inner side of a raceway (47) of the cross roller bearing (4). Thus, the wave gear drive (1) is small and compact, and the rigidity is increased.
