Abstract

The invention discloses a low-speed angular contact ball bearing friction moment measuring device and a loading measuring method and relates to bearing radial load, axial load, moment load, joint loadloading and friction moment measurement. The device is formed by a pedestal, a driving system, a radial load loading system, an axial load loading system, a moment load loading system and a frictionmoment measuring system. For a problem that other components interfere a loading load during an existing angular contact ball bearing friction measuring device load loading process, a closed-loop feedback control system formed by a six-dimensional force sensor, the radial load loading system, the axial load loading system and the moment load loading system is used to eliminate an interference. Inthe invention, a friction moment measurement problem under the continuous high-precision loading of an angular contact ball bearing joint load is solved and friction moment measurement is accurate.

Description

technical field [0001] The invention relates to the field of precision bearing friction torque measurement, in particular to an angular contact ball bearing friction torque measurement device and a loading measurement method, which can realize high-precision continuous loading of single and combined loads of radial load, axial load, and moment load. Background technique [0002] Bearings are an important part of contemporary mechanical equipment, and their precision and life play an important role in the performance of precision equipment. The frictional torque on the bearing is closely related to the life and precision of the bearing. As an important type of bearing, angular contact ball bearings are subjected to complex forces in actual working conditions, and most of them are combined loads, that is, the combination of two or three of radial load, axial load, and moment load. Therefore, it is of great significance to study the friction torque characteristics of bearings u...
