This paper is focusing on the performance enhancement of the tapered roller bearings supporting the transfer shaft in a push belt type Continuously Variable Transmission (CVT). It also provides an objective comparison, based on test results, with the fixed/floating ball bearings alternative arrangement. The influence of different design parameters such as cup and cone race profile, roller length / diameter ratio, surface finish etc., is quantified in the analytical and experimental investigation. The bearings power loss is calculated and measured for operating conditions that are relevant in a vehicle fuel economy cycle. Additional specific aspects related to the use of tapered roller bearings, such as setting and mounting procedures, are discussed under similar considerations. The paper contains a system analysis of the transfer shaft interacting with the variator output shaft and with the differential.
