The Durability and Reliability of Variators for a Dual-cavity Full-toroidal CVT

摘要

A full-toroidal CVT has been expected as a new generation of transmission. However, high contact pressure is needed to generate traction force and temperature due to shear in contact areas becomes very high. Therefore, the fatigue life of variator is insufficient. This paper describe the application of developed Bearing steel to improve the fatigue life of the varitator.
