| Zusammenfassung: | The invention provides a high-speed ball bearing durability assessment test device which comprises a middle shaft, a turbine impeller, a turbine box and a heat shield, the periphery of the middle shaft is fixedly sleeved with the turbine impeller, the periphery of one end of the middle shaft is rotationally sleeved with the turbine box, and the heat shield is arranged on the inner ring of one end of the turbine box. One end of the experiment rotating shaft penetrates through the heat insulation cover and then is fixedly connected to one end of the middle shaft in a sleeved mode, the heat insulation cover is used for blocking the temperature between the interior of the turbine box and the experiment rotating shaft, and compressed air enters the turbine box from the other end of the turbine box and sequentially drives the turbine impeller and the experiment rotating shaft to rotate. According to the high-speed ball bearing durability assessment test device, high-speed running of the high-speed ball bearing can |
