Abstract

The invention relates to a rolling bearing dynamic performance testing machine and a general frame thereof. The general frame includes two installation bases which are arranged at interval in left and right directions and in detachable support scaffold prefabrication with a matching cantilever shafting and a bridge type shafting. The frame also includes two radial loading stations which are arranged in the left and right directions in turn and used for installing radial loading devices so as to apply the radial action force to a test bearing. One of the two radial loading stations is a middle loading station correspondingly arranged between the two installation bases, and the other is an end loading station correspondingly arranged at a left side of the two installation bases. Different shafting can be selected according to actual test requirements, and the radial loading devices are installed to corresponding positions. One set of the general frame can satisfy installation requirements of two sets of shafting, and the universality is good.

Description

technical field [0001] The invention relates to a rolling bearing dynamic performance testing machine and a universal frame thereof. Background technique [0002] Thin-walled bearings for robots are key supporting components of industrial robots. Thin-walled bearings are used in RV reducers on the wrists, elbows, and chassis of robots. With the development of robots in the direction of high precision, high efficiency and long life, the requirements for the running accuracy and reliability of thin-walled bearings for robots are getting higher and higher, and people are increasingly aware of the importance of bearing tests. In fact, the bearing test is an indispensable and important verification process in the bearing design and manufacturing process. On the bearing testing machine, according to the actual working conditions and actual operating conditions of the bearing, that is, the bearing speed, axial load, radial load and ambient temperature , Lubrication state, etc. are...
