Problems solved by technology

However, this device cannot test the dynamic parameters of the bearing under different operating conditions such as rotating speeds.
[0006] It can be seen from the above that there is currently no experimental device to test the dynamic parameters of angular contact ball bearings under different rotational speeds and axial load conditions.

Description

technical field [0001] The invention relates to an experimental device for testing dynamic parameters, in particular to a testing device for dynamic parameters of angular contact ball bearings. Background technique [0002] With the development of high-end CNC machine tools in the direction of high precision, high speed and high efficiency, as the key functional components in the machine tool, the spindle and feed system must have good dynamic characteristics. Angular contact ball bearings are commonly used rotating support components for machine tool spindles and feed systems, and their dynamic parameters have an important impact on the characteristics of machine tool spindles and feed systems and the characteristics of the whole machine. [0003] At present, in terms of experimental analysis of dynamic parameters of angular contact ball bearings, many researchers have carried out multi-faceted and multi-level research, but most of them stay in the study of the influence of...
