Embodiment Construction

[0056]In order to solve the aforementioned problems, according to an embodiment of the present invention, a circular but non-continuous thin groove is cut on the body of the flexspline cylinder. When the wave generator is placed in the inner hole of the flexspline cylinder, the flexspline cylinder The body is constrained by the outer contour of the wave generator, so that the cylinder body is in the shape of a flared bell mouth at the long axis of the wave generator. At this time, due to the presence of ring-row fine grooves in the flexspline body, a discontinuous elastic deformation occurs at the groove position of the flexspline body, which slows down the outward expansion inclination angle of the flexspline body. , thus achieving the effect of increasing the meshing area of ​​the rigid-flex gear teeth. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, wherein the same reference numerals will be used to identify the s...

Abstract

The invention provides a harmonic gear speed reducer. The harmonic gear speed reducer comprises a rigid gear, a flexible gear and a wave generator, the rigid wheel is provided with a plurality of inner teeth, the flexible gear is arranged in the rigid gear and comprises a cylinder body and a plurality of outer teeth, the outer teeth are connected to a first side of the cylinder body and engaged with the inner teeth, the wave generator is arranged in the flexible gear, moreover, a plurality of grooves are formed in the cylinder body and are arranged in at least one row, and the grooves in the at least one row discontinuously surround the periphery of the cylinder body. According to the harmonic gear speed reducer, discontinuous elastic deformation is generated at the positions of the grooves, the external expansion inclination angle of the cylinder body of the flexible gear is slowed down, and the effect of increasing the meshing area of the tooth parts of the rigid gear and the flexible gear is achieved.

Description

technical field [0001] The invention relates to a harmonic gear reducer, in particular to a harmonic gear reducer with an improved flex spline. Background technique [0002] Harmonic gear reducer is a kind of transmission device with high precision, small backlash, high reduction ratio, light weight, small size, large carrying capacity, high efficiency, etc. It has been widely used in aerospace, robots, machine tools, optical instruments And other precision machinery. In addition, solar rotating structures can also be applied. [0003] figure 1 An exploded view of a known harmonic gear reducer is shown. Such as figure 1 As shown, the known harmonic gear reducer 100 mainly includes a rigid spline 101 , a flexible spline 103 and a wave generator 102 (or wave generator). The inner annular surface of the rigid wheel 101 includes an internal tooth portion 111 formed with a plurality of internal teeth. The outer annular surface of the flexspline 103 includes an external toot...
