Bearing Torque Test Device

Abstract

The invention relates to a bearing torque testing device which comprises a bottom plate, a drive unit, a testing unit, an on-line observation unit and a loading unit. The drive unit is fixedly arranged on the bottom plate. The testing unit is connected to the drive unit, and is powered by the drive unit. The on-line observation unit comprises a sensor, and one end of the sensor is connected with the testing unit. The loading unit is connected with the other end of the sensor and is used for loading a tested bearing.

Description

technical field [0001] The invention relates to a bearing torque testing device, in particular to a bearing torque testing device capable of bearing axial load. Background technique [0002] Bearings are indispensable key components in various fields of aviation, heavy industry and advanced manufacturing equipment. According to statistics, about 90% of the bearings currently in use are lubricated with grease. Grease lubrication has incomparable advantages over oil lubrication, namely low friction coefficient, low consumption and no need for additional circulation supply devices. In most cases, grease-lubricated bearings have a longer re-greasing cycle, which greatly reduces manufacturing and operation and maintenance costs as well as energy consumption. The mechanism of grease lubrication is very different from oil lubrication, and grease is more suitable for harsh working conditions such as heavy load and high temperature. Extremely harsh working conditions will lead to ...

AI Technical Summary

Problems solved by technology

For example, the patent No. 201110417343.4 discloses a horizontal bearing friction torque measuring device with a horizontal structure, and realizes loading in two directions at the same time, which can more closely simulate the actual working conditions of the bearing; for example, the patent No. 201310517828.X Disclosed is a test device and method for friction torque under actual working conditions of bearings. Using the characteristics of the micro-friction torque of the air flotation platform to test the friction torque under actual working conditions (different preloads) of bearings, it solves the problem of existing bearing friction. The technical problem that the torque testing instrument cannot fully simulate the friction torque of the bearing in the actual working condition

[0004] Although the test equipment in the above disclosed patents can further simulate the actual working conditions of the bearings, most of the bearing test benches have complex and large structures at present, and are not easy to disassemble, which affects the measurement accuracy and cannot perform in-situ inspection of the lubricant in the bearing after work. sampling
