Embodiment Construction

[0058] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0059] The object of the present invention is to provide a method for reverse active modification of the tooth profile of the RV reducer cycloid, such as figure 1 As shown, the method first obtains the modified cycloid gear tooth profile model according to the displacement, equidistant and rotation angle modification methods; then according to the modified cycloid gear tooth profile model and the unmodified pin gear tooth profile model, the cycloid The initial modification reference point of the wheel, calculate the initial rotation angle of the pin wheel and the cycloid wheel when the initial modification reference point meshes, and calculate the transmission error and return error according to the initial rotation angle; then the maximum transmission error value is the smallest, and the return error value is the smallest Objective, establish the...

Abstract

The invention provides a cycloidal gear of an RV reducer and a reverse active tooth profile modification method thereof. On the premise of comprehensive consideration of the actual transmission errorand hysterisis error requirements, reverse active profile modification design is carried out on a cycloidal gear tooth profile, a cycloidal gear design tooth profile more in line with the engineeringpractice is acquired while the meshed characteristics and movement precision are ensured, not only is the assembly manufacturability of an RV reducer cycloidal pin wheel set ensured, but also the interactive influence among the shape change of a cycloidal tooth profile, the meshed characteristics and the movement precision is comprehensively considered, so that the tooth profile modification quality and transmission quality are both effectively improved, and it is of great significance to the pre-control of the transmission performance and improvement of the movement precision of the RV reducer.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of a cycloidal wheel, in particular to a cycloidal wheel of an RV reducer and a tooth profile reverse active modification method thereof. Background technique [0002] RV (Rotary Vector) reducer is the core component of robot equipment, and its transmission quality directly affects the motion performance and repeat positioning accuracy of the robot. The robot requires high positioning accuracy and transmission accuracy, which mainly depends on the transmission error and return error requirements of the RV reducer. Among them, the cycloid pin wheel planetary transmission directly connected to the output shaft of the RV reducer has the greatest impact on the RV motion accuracy. The key technology involved is the design technology and manufacturing process of the cycloid pin wheel, and the tooth profile modification of the cycloid wheel The quality of shape design is difficult.
