Modelling and Simulation of Dual-Pinion Driving Systems for Backlashes Elimination

Abstract

This paper develops a dynamic model for the dual-pinion system. A dual-pinion system consists of two driving pinions and a loading gear, which is often used in the power train of high-powered machine to share the load and the precision manufacturing machine to take up the backlashes. To consider the complicated effects of backlashes and non-linear mesh stiffness between the pinions and the gear, an average dynamic model of a spur gear-pinion pair is constructed at first. Then, the dynamic model of the dual-pinion system is developed, wherein the backlashes and average Hertzian mesh stiffness are included. The derived models are believed to be useful in designing an intelligent controller for the dual-pinion system.

Key Words:

• Dual-pinion
