Abstract

The method to analyze the dynamic characteristics of the inter-shaft bearing in the dual rotor system is presented. Under different radial loads, the distributions of minimum oil film thicknesses and contact loads between rollers and raceways are obtained. The results show that the rollers' spinning angular speed decreases and the number of loaded roller increases with the increase in the radial loads of inter-shaft bearing when the rotational directions of outer ring and inner ring are same. The minimum oil film thickness between each roller and inner raceway is thinner than that between each roller and outer raceway in loading region. The rollers' spinning angular speed increases with the increase in the rotational speeds of outer ring, and it decreases with the increase in the rotational speeds of inner ring.
