Exploration of Maintenance of Flywheel Device Used in HS-X Hydraulic Dynamometers
During engine testing, the flywheel device installed in HS-X hydraulic dynamometers underwent a bearing temperature alarm failure. The flywheel device was decomposed, inspected and tested for failure, repaired, assembled and adjusted. It was found that the main causes of overtemperature of flywheel device bearing were bearing damage and unqualified size. By replacing the bearing, readjusting the bearing fit of the flywheel device, and adjusting the runout of the rotor assembly and dynamic balance, the domestic independent maintenance support of the flywheel device is completed.
