Oil injection lubrication analysis of a silent chain drive system

Abstract

Previous investigations on oil lubrication have mainly focused on gear transmission systems. There has been little research on injection lubrication of silent chain drive systems. In this study, a high-fidelity 3D model of a silent chain drive system is established, and the stability of the model is verified through simulation analysis. Using the moving particle semi-implicit (MPS) method, the flow field distribution of the silent chain drive system under the coupling of multiple fields is obtained through co-simulation with RecurDyn and Particleworks. The effects of key parameters, including sprocket speed, injection quantity, lubricant viscosity, and injection angles, on the lubrication performance of the silent chain drive system are investigated. These results provide a reference for future practical application and theoretical research of oil injection lubrication for chain drive systems.
