Description

technical field [0001] The invention relates to a bearing performance simulation test device and a test method, in particular to a spiral groove gas dynamic pressure thrust bearing performance simulation test device and a test method. The invention belongs to the technical field of aerospace bearing testing. Background technique [0002] The spiral groove gas dynamic pressure thrust bearing generates gas dynamic pressure through high-speed rotation, and forms a gas film between the two working surfaces to realize gas lubrication and ensure safe and reliable operation of the bearing. According to different application environment requirements, the gas lubrication medium of this type of bearing can be air, nitrogen, helium, hydrogen, etc. Under the action of high-speed gas lubrication, the gas dynamic pressure thrust bearing has the advantages of low friction, zero wear and long life. However, during the start-stop process of the bearing, the gas dynamic pressure effect is in...
