Precision Assembly and Adjustment Technology for Satellite Momentum Wheel Bearing Components
The preload force of the momentum wheel bearing component in satellite actuators is an important factor affecting the stiffness and fatigue life of angular contact ball bearings.The appropriate preload force and consistency selection of a certain type of bearing component are determined through Hertz stress to prevent excessive contact stress from causing bearing fatigue damage.By using axial displacement theory,the actual grinding amount of the inner and outer spacer rings has been corrected to improve the efficiency of bearing preloading configuration.Through the running in test of the bearing components,the motor current is stable and the friction torque is controlled to provide the technical support for the stable operation and long service life requirements of the satellites momentum wheels.
