Problems solved by technology

The test bearing of this testing machine is installed in the middle of the main shaft, and it is inconvenient to disassemble the bearing. The rotation and swing angle of the main shaft needs to be measured and controlled by an angle encoder in real time, and the degree of automation is not high enough. Rotation and swing, resulting in inconvenient clamping of the temperature sensor

Abstract

The invention relates to a frictional wear life testing machine for a self-lubricating joint bearing. The testing machine comprises a testing machine bottom plate, a mounting bottom plate, a supporting base, a frictional wear system, a power transmission system, a loading system and a data acquisition and processing system. The power transmission system penetrates through the testing machine bottom plate, the mounting bottom plate and the supporting base from bottom to top. The frictional wear system is fixed to the top of the supporting base, the loading system is installed on the mounting bottom plate, and the frictional wear system is connected with the loading system through a traction rope. A signal line of the data acquisition and processing system is connected with the frictional wear system and the loading system. According to the invention, a test basis can be provided for accurate prediction of the life of a bearing, and a data basis is provided for establishment of a self-lubricating joint bearing life model.

Description

technical field [0001] The invention belongs to the field of bearing performance and life testing, and in particular relates to a friction and wear life testing machine capable of testing the service performance and running life of self-lubricating joint bearings. Background technique [0002] Joint bearings are slewing support mechanical parts widely used in aerospace, heavy machinery and other fields. Because self-lubricating joint bearings have the advantages of self-aligning and no need to add lubricants, the requirements for their performance and operating life have become more stringent in practical applications in recent years. In order to predict the performance and service life of joint bearings before they are put into use, domestic joint bearing-related manufacturers and research institutes have developed a number of joint bearing performance testing machines, joint bearing life testing machines, etc., but the existing joint bearing testing machines All need to b...
