The Pulley Grooves Wear Interpret Analytical form Based on the Hertz Contact Theory and Finite Element Analysis
Zhu Qing, Shuisha Ling

Abstract
Using mechanics basic theory, the Hertz contact theory and finite element analysis ANSYS, the aim is to study the contact problem of wire rope and pulley, and establish the contact model of wire rope and pulley. The theory and simulation result are effective to explain the wear of pulley groove. According to the analysis results from the design and use of pulley, putting forward some measures on how to avoid pulley wear and wear indentation after processing method, which can effectively extend the service life of the pulley, as well as provide certain theoretical support for the pulley processing technology.
