A shaft drive (10), which may be produced without problem and easily—even in a cascade—assembled, may be achieved, whereby the support ring (18) produced such as to be floating relative to the housing is rotationally fixed on the front side to a housing base plate (12) and enclosed by a housing cover (20), similarly fixed to the base plate (12), in which the drive shaft (25) for the crowned drive ring (27), which may rotate relative to the support ring (18), has a floating bearing. The inner wheel (28), extending through both rings is however not supported in the housing, but rather mounted on the drive shaft (14) extending coaxially into the housing (11) through the base plate (12), by means of the wave generator drive core (30), the base plate (12) being non-rotationally mounted in front of the bearing plate (32) of the above.
A harmonic drive (10) having a housing baseplate (12) with a central hole and having a wave generator drive core (30) in a revolvingly radially deformable internal geared wheel (28), which extends axially through a radially dimensionally stable support ring 18), which is fixed to the housing, into a cap-shaped, radially dimensionally stable driven ring (27) mounted using its driven shaft (25) in the housing (11), each of somewhat greater internal diameter than the non-deformed internal geared wheel external diameter, characterized in that a housing-independent support ring (18) is mounted on its face on the baseplate (12) and is overlapped by a housing cup (20), whose bottom (23) is equipped with the bearing (24) for the driven shaft (25) and whose front edge, opposite the bottom (23), is rigidly connected to the baseplate (12).
The harmonic drive according to the preceding claim, characterized in that the baseplate (12) is equipped with a profiled edge region (16) for form-fitting accommodation of the support ring (18) and the housing cup (20).
The harmonic drive according to the preceding claim, characterized in that the hollow-cylindrical wall (21) of the cup (20) is equipped with spring hooks (22) for engaging behind the baseplate (12).
The harmonic drive according to one of the preceding claims,
The harmonic drive according to one of the preceding claims,
The harmonic drive according to one of the preceding claims,
The harmonic drive according to the preceding claim,
The harmonic drive according to the preceding claim,
The harmonic drive according to one of the preceding claims,
