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

Abstract

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.
