Research on Pulley Deformation of Metal Belt Continuously Variable Transmission 2010-01-1977

Pulley deformation is one of the factors(the belt's deflection, power lose of hydraulic and lubrication) affect transmission efficiency of metal belt CVT. It leads to the cause of the metal belt deflection, intensifies whole-Part wear and reduces the life-span of the CVT. In this paper, the pulley deformation has been analyzed by finite element software, and the results indicate that with the increase of transmission ratio, the driver pulley deformation decreases, stress is increases after reduces for a while, and the driven pulley deformation and stress increase. These results from finite element analysis are in agreement with those from others experimental data, whereby demonstrating that the established finite element model is rational and that the analysis results are reliable.
