非圆齿轮无级变速器力矩特性分析

Analysis of Moment Characteristic of Non-circular Gear Continuously Variable Transmission

针对传统无级变速器无法适应高转速、大转矩的工作环境,给出了一种无内部循环力矩的加法器式非圆齿轮无级变速传动方案。分析了变速器在相对恶劣工况下的力矩特性和非圆齿轮轮齿载荷情况;推导了此类齿轮组结构惯性力矩、负载力矩及发动机驱动力矩的计算通式,为该型无级变速器的优化设计和生产加工提供了理论参考。

Considering traditional continuously variable transmission cannot adapt to the working environment of high speed and high torque,an adder-type non-circular gear continuously variable transmission scheme without internal circulating torque is given. The torque characteristics and load conditions of non-circular gear teeth under relatively harsh working conditions are analyzed. General formulas for calculating the inertia moment,load moment and engine driving moment of this type of gear set are deduced,which provide a theoretical reference for optimal designs,production and processing of this type of continuously variable transmission.
