Embodiment Construction

[0012] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0013] Such as figure 1 As shown, a harmonic reducer has a wave generator, a flexible spline 2 and a rigid spline 3, and the wave generator is installed inside the flexible spline 2. Due to the elliptical structure of the wave generator itself, the flexible spline 2 produce flexible deformation. The middle part of the wave generator is connected to the input shaft, and the input shaft drives the wave generator to rotate. Therefore, the flexible spline 2 deforms periodically with the rotation of the wave generator. In addition, if figure 2 As shown, the outer side of the flexspline 2 has external meshing teeth 21 through which the flexspline 2 meshes with the rigi...

Abstract

The invention discloses a harmonic reducer which comprises a wave generator, a rigid wheel and a flexible wheel. The wave generator comprises a flexible bearing and a cam mechanism. The cam mechanism comprises a first cam and a second cam. The first cam and the second cam are coaxially arranged and equal in size and thickness, and an angle is formed between the first cam and the second cam and is 0-45 degrees.

Description

technical field [0001] The present invention relates to a reducer, in particular to a harmonic reducer. Background technique [0002] Motion accuracy is an important indicator of the harmonic reducer. Generally speaking, the motion accuracy can be improved by matching processing and improving the processing accuracy. However, the processing accuracy of the machine tool is limited, and it is very difficult to improve it to a certain extent. Therefore, in view of this technical problem, a more optimized design is needed to solve the above problems and further improve the motion accuracy. The movement accuracy can be improved by reducing the meshing gap between the rigid spline and the flexible spline, so a mechanism is needed to effectively reduce the meshing gap between the rigid spline and the flexible spline. Contents of the invention [0003] The present invention provides a harmonic reducer, including a wave generator, a rigid spline, and a flexible spline, wherein the...
