Service life verification tester for ceramic bearing

Abstract

The invention provides a service life verification tester for a ceramic bearing. The service life verification tester is characterized by comprising a transmission system, a loading system, an environment simulation system and a measuring system, wherein the transmission system is used for transmitting dynamic force and driving a test spindle (19) equipped with a test bearing (14) to rotate so as to calculate the service life of the test bearing (14); the loading system is used for loading the test bearing (14) according to actual loading conditions; the environment simulation system is used for simulating high temperature, no lubrication, helium gas and graphite dust in an actual operating environment; and the measuring system is used for measuring environmental parameters and status parameters of the test bearing (14) during a test process. The service life verification tester for the ceramic bearing has the advantages of being capable of verifying the service life of the ceramic bearing in the atmosphere with high temperature, no lubrication and helium gas, being good in reusability, being capable of performing verification tests on the service lives of ceramic bearings in various specifications, and saving cost.

Description

technical field [0001] The invention relates to the technical field of ceramic bearings, in particular to a life verification test device for ceramic bearings under high temperature, no lubrication, and helium atmosphere. Background technique [0002] The high-temperature gas-cooled reactor is a high-temperature reactor with graphite as the moderator and helium as the coolant. It is an advanced nuclear reactor with good inherent safety, high power generation efficiency, and extremely wide uses. The main helium blower, control rod drive mechanism, absorber ball shutdown system and fuel loading and unloading system in the primary circuit of the high-temperature gas-cooled reactor nuclear power plant all include moving equipment, which need to be supported by bearings. The reliability of the bearings is very important. However, some bearings of these four systems will work under high temperature, no lubrication, and helium atmosphere, and the working environment temperature of ...
