Technical Field

The invention relates to a conical uniform-thickness flexible gear for harmonic gear transmission, and belongs to the technical field of harmonic gear transmission.

Background

The harmonic gear transmission is a gear transmission mode for transmitting motion or power by using controllable elastic deformation waves generated by a flexible gear, mainly comprises three basic components of a flexible gear, a rigid gear and a wave generator, and has the working principle that: when the wave generator rotates continuously, the wave generator forces the flexible gear to deform and shift continuously, the teeth of the flexible gear are sequentially engaged and shifted from the engaged direction to the disengaged direction, and then disengaged from the disengaged direction and engaged from the disengaged direction to the engaged direction, so that the flexible gear rotates along the opposite direction of the wave generator.

Disclosure of Invention

The invention aims to provide a conical uniform-thickness flexible gear for harmonic gear transmission, wherein after a cam wave generator with a flexible bearing is installed in the flexible gear, under the action of an expansion deformation inclination angle beta generated by the flexible gear in the long axis direction, gear teeth generate different deformation amounts along different axial sections, and the deformed flexible gear teeth and rigid gear teeth keep good meshing states in all axial sections, so that the defects of the prior art are overcome.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention relates to a conical uniform-thickness flexible gear for harmonic gear transmission, which comprises a flexible gear ring used for being installed with a cam wave generator, wherein a conical gear is arranged on the outer wall of the flexible gear ring.

In the conical uniform-thickness flexible gear, an included angle delta is formed between a gear tooth pitch circle line of the conical gear and a rotary central axis of the flexible gear ring; the included angle delta is the same as the camber deformation inclination angle generated by the flexible gear ring in the long axis direction after the cam wave generator is installed.
