Research on Pulley Deformation of Metal Belt CVT

Abstract

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.

摘要：

带轮变形是影响金属带式无级变速器传动效率的众多因素之一。它会导致金属带的偏斜,加剧变速器各部件间的磨损,缩短变速器使用寿命。采用ANSYS软件对带轮变形进行分析,确定NDIV编号为20时的网格划分模式,分析结果表明,随着传动比的增大,主动轮变形减小、应力则是先减小后增大,从动轮变形和应力增大。分析结果在一定程度上与其他学
