Aiming at the high temperature rise of bearings in a flywheel device for test equipment during the operation, the many possible factors influencing the temperature rise of bearings are experimentally analyzed.The corresponding improvement measures are proposed.The experimental results after improvement show that the temperature rise of bear-ings is effectively reduced by increasing heat transfer area,improving air flow speed and changing seal structure,and the operating requirements of host are satisfied.
