Product Description

Momentum Wheel and Its Subassembly

      The momentum wheel is a key component of the satellite attitude control system. The bearing subassembly is the core component of the momentum wheel. The momentum wheel and its subassembly are applied in all the satellites, of which the reaction-torque produced by the gyroscopic stability and the variation is used to stabilize or change the attitude of a satellite. The service life, precision and reliability of the momentum wheel and its subassembly have a great influence on the service life, precision of controlling and reliability of a satellite.

     Through researches, with a rotating speed of 4,600rpm, the friction torque has been lowered from 180g.cm to 140g.cm, and the fluctuation has been lowered from 10% to 5% by our company. The precision has been raised from P4 to P2 (the highest level in the world). The service life has been increased from 2 years to 5 years. More than 100 bearing subassemblies of 4 types have already been applied in the satellite momentum wheels of several models, which are all working normally. Some of the bearing subassemblies have passed the working life examinations.
