Abstract

The invention provides an integrated type double-rigid-wheel harmonic speed reducer without an inner and outer ring rolling needle type flexible bearing. A new wave generator, a new inner ring, a new outer ring, a new flexible wheel, a rolling needle, rigid wheel end covers and a deep groove ball bearing are included; the new wave generator is composed of a wave generator body and a rolling needle flexible bearing inner ring; the new flexible wheel is composed of a flexible wheel body and a rolling needle flexible bearing outer ring; the new inner ring is composed of a fixed rigid wheel and a crossed roller bearing inner ring; the new outer ring is composed of an output end rigid wheel and a crossed roller bearing outer ring; and the new wave generator, the new inner ring, the new outer ring and the new flexible wheel are all integrated parts. In the technical field of harmonic speed reducers, the problems that a gap is likely to exist in the radial direction of the speed reducer, transmission is not stable, and rigidity is poor exist, and the double-rigid-wheel harmonic speed reducer which is small in body type, small in weight, compact in structure and high in rigidity is provided.

Description

technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to an integrated double rigid wheel harmonic reducer without inner and outer ring needle roller flexible bearings. Background technique [0002] The double rigid wheel harmonic reducer is a reducer mainly composed of a wave generator, two flexible bearings, and two rigid wheels. The rigid wheel and the flexible wheel at the fixed end mesh with the same number of teeth, and the rigid wheel and the flexible wheel at the output end For differential tooth meshing, the transmission obtains a reduction ratio. [0003] Chinese patent CN205877115U discloses a harmonic reducer with an improved structure, including cross roller bearings, an elliptical wave generator, a flexible bearing mounted on the elliptical wave generator, and a circular flexwheel and a flexwheel installed on the flexible bearing The rigid wheel is mounted on the outside; the flexible bearing is a cylindrical r...
