Forced oil lubricated high-speed rolling bearing test bench

Abstract

The invention discloses a forced oil lubricated high-speed rolling bearing test bench. The forced oil lubricated high-speed rolling bearing test bench is composed of a base, a filter, an oil pump, an oil tank, oil pipes, tee interfaces, a motor, a coupling, a rotation shaft, flat keys, positioning shaft sleeves, bearings, a loading bearing, a test bearing, oil spray rings, bearing block lower parts, bearing block upper parts, a loading bearing block, snap rings, a round nut, bearing end covers, felt collar oil seals, a threaded loading rod, a bracket, a washer, a fastening bolt and the like. According to the forced oil lubricated high-speed rolling bearing test bench, a structure according to which two pairs of bearings are arranged side by side to support the rotation shaft is adopted; the oil pump is adopted to provide lubricating oil for the high-speed rolling bearing test bench; the filter is adopted to purify the lubricating oil; and therefore, the high-speed and stable operation of the test bench can be realized; and the cooling cyclic utilization of the lubricating oil is realized, so that the lubrication performance of the lubricating oil can be improved. Compared with an existing bearing test bench device, the device of the invention has the advantages of reliable performance in high-speed operation, convenient disassembly and simple and convenient operation, and is especially suitable for high-speed rolling bearing tests and other conditions where bearings generate a lot of heat.

Description

technical field [0001] The invention relates to a rolling bearing test stand, in particular to a pressure lubricated high-speed rolling bearing test stand. Background technique [0002] Rolling bearing is one of the important basic parts in industrial machinery and equipment, and its working performance directly determines the operation performance of the whole machine. Rolling bearings are usually composed of four parts: outer ring, inner ring, rolling element and cage. Its function is to support the rotating parts in the machine to reduce the friction in its motion and ensure the rotation accuracy of the rotating parts. With the continuous improvement of various mechanical precision, rapidity and reliability requirements, it is particularly important to conduct experimental research on rolling bearings, so it is necessary to design a rolling bearing test bench that can adapt to high-speed conditions. [0003] At present, most of the rolling bearing test benches on the mar...
