摘要

Rotation torque, to reduce the stirring resistance of oil and roll viscous drag, is realized through setting roller filling 0. by reducing7-0.92 range and ratio roller length and the range of roller diameter are 1.1-1.7. In addition, to reduce rolling viscous drag, by application convex surface processing rotation torque where outer ring convex surface machined parameters (=RCO/LRO) be 30-150 and inner ring parameter (=RCI/LRI) is 50-260, with RCO by outer ring convex surface radius of machining, length LRO outer ring raceways, RCI inner rings convex surface radius of machining, the length inner ring raceway of LRI.
