摘要
基于金属带式无级变速器(MB-CVT)的基本结构,通过引入无接头钢丝绳和改变金属块形状,设计了一种新型金属带式无级变速器,即Wire Rope-CVT(WR-CVT)。通过对比分析了两种CVT钢带环/钢丝绳在6个自由度方向上的约束情况,认为WR-CVT具备MB-CVT稳定的工作状态。获得了WR-CVT钢丝绳与金属块圆弧槽接触时横向正压力计算公式,分析了WR-CVT钢丝绳与金属块圆弧槽纵向接触和非接触时的作用力关系,为WR-CVT的进一步研究奠定了基础。
The basic structure based on metal belt CVT （Metal Belt Continuously Variable Transmission, referred to as MB - CVT） , through the introducing the jointless wire rope and changing the metal block shape, a new type of metal belt CVT is designed, namely the Wire Rope - CVT （ WR - CVT）. Through the compara- tive analysis the constraint condition of two kinds of CVT metal belt ring and wire rope in six degrees freedom, the result shows that the WR - CVT has a stable working state of MB - CVT. The formula of calculating lateral pressure of WR - CVT wire rope and metal block arc groove contact is obtained, the analysis of WR - CVT wire rope and metal block arc groove longitudinal contact and non -contact the relationship of force are carried out, the foundation for the further study of WR - CVT is provided.
