某轻型高机动装备无级变速器皮带轴向偏移分析

CVT Belt Axial Offset Analysis of a Certain Light and High Mobility Equipment

阐述了橡胶带式无级变速器的调速原理，分析了该无级变速器皮带轴向偏移的原因和带来的危害，采用数值求解的方法求出了皮带轴向偏移的大小，提出了消减皮带轴向偏移的2种方法，有效地改善了皮带轴向偏移问题。结果可作为无级变速器传动设计、强度校核、变速控制的基础。

This paper described the variable speed control principle of the rubber belt continuously variable transmission （CVT）, analyzed the reason of the axial offset of the rubber belt CVT, and the harm caused by the offset, calculated the axial offset size of the belt using the method of the numerical solution, proposed two ways to reduce the axial offset of the belt which can effectively improve the problem of the axial offset. The results can be used as the basis of CVT transmission design, strength check and variable speed control.
