Abstract

Abstract

A research work for developing aeroengine high-speed roller bearings with2. 5×10⁶ DN has been completed. At first, a front roller bearing of a turbine rotor on an existing engine was tested to expose its defects as its DN was enhanced. Then, a new bearing 5D2002832N W has been designed to eliminate the these defects, the comparative tests have been carried out. The results show that the new bearing can meet the requirements of the roller bearing working at 2. 5×10⁶ DN, when its design parameters are chosen reasonably.
