Study on contact angle of double-decker bearing with consider of centrifugal expansion

Improving the precision of numerical calculation double-decker bearing is basis exploring its potential application value. This paper takes as research object, a modified quasi-statics model was established by considering influence centrifugal expansion inner and middle ring at high speed solve it with soft Matlab. The on contact angle analyzed. results show that caused under can not be ignored, has greater than outer bearing. dynamic properties different materials different, change ceramic steel. It provides for more accurate analysis design
