Research on failure simulation of the feeding system considering transmission gear wear

Abstract

The feeding process of the feeding system in the power transmission chain was a high-speed, high impact, non-stationary process, and easy to detect functional faults, aimed at the problem, based on nonlinear multi-body dynamics and Dubowsky contact modeling theory, a gear transmission modeling method including backlash was proposed. A dynamic simulation model of the feeding system injected with gear wear fault was established, and the system dynamic performance under different wear levels was analyzed. The research results show that due to the wear of the gear teeth, the contact force between the teeth increased by about 70%. When the wear of a single tooth pair increased to 0.2mm, there would be jamming faults caused by delayed chain throwing. The research results provided support for the optimization and improvement of the feeding system.
