Abstract

The harmonic gear cold rolling process is an effective method to solve mass production. However, tooth profile quality problems greatly hinder the development of the process. Based on engagement theory, the dynamic characteristics of the rolling process and flexible wheel rolling tooth profile errors caused by the changes of the number of contact points were analyzed and studied, and the process methods were put forward to eliminate or reduce tooth profile errors in this paper, which has an important significance in analysis of rolling tooth profile errors, modification shape of the rolling wheel, optimization of process parameters and improvement of gear rolling quality.
