Abstract

The invention discloses a bearing testing machine. The bearing testing machine comprises a testing bench, a bearing carrying mechanism, a pressure mechanism and an impact testing mechanism. The testing bench is arranged on the middle part of a machine frame. The bearing carrying mechanism comprises a tested bearing cover, a tested bearing seat and a bearing driving motor. The tested bearing cover is installed on the upper end of an inner ring of a tested bearing. The tested bearing seat is fixed on the testing bench and is connected with an outer ring of the tested bearing. The bearing driving motor is connected with the lower end of the inner ring of the tested bearing. The pressure mechanism comprises a pressing-down oil cylinder arranged above the testing bench, and a piston rod of the pressing-down oil cylinder is coaxial with the tested bearing cover. The impact testing mechanism comprises a grasping mechanism, a pair of lifting oil cylinders and a testing block. The grasping mechanism comprises a pair of grasping cylinders, and a pair of manipulators connected to piston rods of the pair of grasping cylinders. The pair of lifting oil cylinders is installed at two sides of the testing bench. The bearing testing machine provided by the invention is capable of well simulating a practical condition in which the bearing is impacted and well reflecting the practical service lifetime of the tested bearing.

Description

technical field [0001] The invention relates to a bearing testing machine. Background technique [0002] With the development of science and technology, there are more and more bearing products, and manufacturers have higher and higher requirements for bearing tests. People are also increasingly aware of the importance of bearing tests. In the stage of bearing product development, what is to be done is the test of the bearing structure. Whether the test product can meet the working conditions of its bearing is mainly the assessment of the bearing structure. After the product finalization test, it is mainly to assess the quality of the bearing, identify the quality level of the bearing product, and promote the improvement of the quality, so as to find the problem in a weak link such as the bearing structure, material, and manufacturing process, and control it. Therefore, the bearing test is an indispensable and important verification process in the bearing design and manufa...
