Abstract
A harmonic drive including a housing component (4) and a drive element (18) which is held on the housing component, can be deformed by a wave generator (14), is in the form of a flanged bushing and has a toothing region (17) having a cylindrical basic shape and a disc section (19) which adjoins the toothing region (17). Adjoining the disc section (19) there is a bushing section (20) which is concentric to the toothing region (17), overlaps the latter in the axial direction and is held interlockingly between a cylindrical edge section (21), which is thick-walled in comparison with the bushing section (20), of the housing component (4) and an intrinsically rigid component (22) which is likewise solid in comparison with the flanged bushing (18).
Claims18
A harmonic drive, comprising:
- a housing component;
- a drive element held on said housing component, said drive element is deformable by way of a wave generator, is configured as a flanged bushing, and has a toothing region with a cylindrical basic form and a disk section which adjoins the toothing region;
- a bushing section adjoins the disk section, the bushing section is concentric with respect to the toothing region, overlaps the toothing region in an axial direction, is held in a positively locking manner between a cylindrical, thick-walled, in comparison with the bushing section, edge section of the housing component and a solid, in comparison with the flanged bushing, inherently rigid component, and is adapted to permit a relative rotation in the case of high torques up to a positively locking connection between the bushing section and the housing component or the rigid component.

- a bushing section adjoins the disk section, the bushing section is concentric with respect to the toothing region, overlaps with the toothing region in an axial direction, is held in a frictionally locking manner, in case of low torques, between a cylindrical, thick-walled, in comparison with the bushing section, edge section of the housing component and a solid, in comparison with the flanged bushing, inherently rigid component, and is adapted to permit a relative rotation in case of high torques up to a positively locking connection between the bushing section and the housing component or the rigid component.
