Abstract:

Pulley deformation is one of the factors affecting transmission efficiency of metal belt CVT. It leads to the cause of the metal belt deflection, intensifies whole-part abrasion and reduces the life-span of the CVT. The pulley deformation was analyzed by finite element software ANSYS herein, determined the mesh partition mode when NDIV No. of element division is 20, the results indicate that with the increase of transmission ratio, the driving pulley deformation decreases, stress is increases after reduces for a while, and the driven pulley deformation and stress increase. The results from finite element analysis are in agreement with those from other’s experimental data, whereby demonstrating that the established finite element model is rational and that the analysis results are reliable.
