Rolling bearing performance test equipment for turbine pump

Abstract

The invention relates to rolling bearing performance test equipment for a turbine pump. The rolling bearing performance test equipment comprises a tested rolling bearing assembly, a shaft system assembly and a shell assembly. According to the tested rolling bearing assembly, installation of a tested rolling bearing, a pre-tightening element wave spring and a bearing sleeve is achieved, a lubricating and cooling channel of the tested rolling bearing is achieved through a hole formed in an assembly shell, and radial load loading of the tested rolling bearing is achieved by conducting spring loading on the assembly shell. The shaft system assembly realizes high-speed operation of the whole test equipment, is driven by an axial-flow turbine, sequentially transmits power to the tested rolling bearing assembly through a shaft system, is mounted and supported on the shell assembly through a rolling bearing on the shaft system, and is lubricated and cooled through oil mist or oil gas, and is axially pre-tightened through the wave spring; the shell assembly provides a mounting space, the axial-flow turbine is driven by the supersonic nozzle on the shell assembly, and the radial load loading of the tested rolling bearing assembly is realized by the loading spring on the shell assembly.

Description

technical field [0001] The invention relates to a rolling bearing performance testing device, in particular to a rolling bearing performance testing device for a turbo pump. Background technique [0002] In the process of product acceptance and bearing performance testing for rolling bearings used in aerospace servo turbo pumps, it is often necessary to conduct helium blowing tests through assembly process turbo pumps to test bearing performance. This requires not only process turbo pumps, but also supporting hydraulic source and other process equipment. , and once the process turbine pump is assembled and debugged, it can no longer be disassembled. During the bearing performance assessment process using the process turbine pump, the axial preload and radial load of the rolling bearing cannot be controlled at any time. The performance parameters of the bearings under the conditions cannot be measured, and in the assembly of the turbo pump, the rolling bearing and the mechani...
