Abstract
A harmonic drive comprises a wave generator, a resilient, geared transmission element that can be deformed by the wave generator, a connecting element on the housing side, and a connecting element on the output side. The resilient transmission element has two different tooth systems, a spline tooth system and a running tooth system; the spline tooth system is coupled along the entire circumference to one of the connecting elements for conjoint rotation therewith, and the running tooth system is provided for cooperation with the wave generator and partial engagement in a mating running tooth system on the other connecting element.
Claims19
A harmonic drive comprising:
- a wave generator,
- a flexible, toothed transmission element that can be deformed by the wave generator,
- a first connecting element on a housing side, and
- a second connecting element on an output side, and
- the flexible, toothed transmission element has a spline tooth system and a running tooth system, the spline tooth system coupled along a circumference of one of the first or second connecting elements for conjoint rotation therewith, and the running tooth system provided for interaction with the wave generator and partial engagement in a mating running tooth system on the other one of the first or second connecting element, and
- the spline tooth system and the running tooth system are nested radially within one another and overlap in an axial direction.
A harmonic drive comprising:
- a wave generator,
- a flexible transmission element deformable by the wave generator,
- a first connecting element on a housing side, and
- a second connecting element on an output side, and
- the flexible transmission element configured with a spline tooth system and a running tooth system, the spline tooth system coupled along a circumference of one of the first or second connecting elements for conjoint rotation therewith, and
- the running tooth system provided for interaction with the wave generator and partial engagement in a mating running tooth system on the other one of the first or second connecting element, and
- both the spline tooth system and the running tooth system are configured as external tooth systems.
A harmonic drive comprising:
