Problems solved by technology

[0006] However, there are still deficiencies in Patent Document 4, that is, it does not distinguish the modulus on the neutral line (circle) of the flexspline from the modulus on the indexing circle, resulting in an impact on the trajectory of the flexspline relative to the rigid spline. It also affects the inclination phenomenon of the tooth profile, which has an important impact on the final tooth profile and the transmission performance of the gear

Abstract

The invention discloses a harmonic gear device adopting a non-interference and wide range meshing tooth profile. The harmonic gear device adopting the non-interference and wide range meshing tooth profile comprises a steel wheel having internal tooth, a flexible gear arranged in the steel wheel and having external tooth, and a wave generator mounted in the flexible gear; the internal tooth is meshed with the external tooth, the tooth profile of the internal tooth and the external tooth can be obtained by following formula: the formula is as shown in specification; the harmonic gear device adopting the non-interference and wide range meshing tooth profile has more reasonable tooth profile and can meet better tooth profile meshing performance.

Description

technical field [0001] The invention relates to a harmonic gear device, in particular to a harmonic gear device with non-interference and large-range meshing tooth profiles. Background technique [0002] Harmonic gear transmission is a transmission method that relies on the elastic deformation of flexible gears to transmit force and motion. A typical harmonic reducer consists of three components: a flex spline, a rigid spline and a wave generator. Usually, the rigid spline is fixed, and the wave generator is an elliptical component, which is installed inside the flexspline, forcing the flexspline to deform radially at the end of the long axis into an ellipse according to certain rules. When the wave generator is driven to rotate, the flexible spline is forced to continuously deform. During the deformation process, the flexible spline gradually enters between the rigid spline teeth, meshes with the rigid spline teeth, and then gradually withdraws until it is completely disen...
