Slow-speed heavy-load fibrage composite self-lubricating bearing strip performance test machine

Abstract

The invention discloses a performance tester for a low-speed heavy-load self lubrication liner of fibrage compound. The invention is characterized in that a rotating shaft (37) is installed on the wall of an enclosed box body (14) through a bearing, an outer sphere (35) with an inner hole is fixedly connected in the middle of the rotating shaft (37), a first fibrage compound self lubrication liner (12) and a second fibrage compound self lubrication liner (15) are matched with the outer sphere (35), the shaft end of the rotating shaft (37) is connected with a torsionmeter (29) through a coupling (28), the torsionmeter (29) is connected with a reduction gear (31) through a coupling (30), and the reduction gear (31) is connected with the output shaft of a servo motor (33) through a coupling (32). The performance tester can simulate the real operating mode condition of the low-speed heavy-load self lubrication liner of fibrage compound to perform frictional wear test, abrasion fatigue test and performance optimization test for the low-speed heavy-load self lubrication liner of fibrage compound, and the change of the abrasion condition and the friction force of the low-speed heavy-load self lubrication liner of fibrage compound can be monitored in real time, and meanwhile, the performance tester has the advantages of compact structure, artistic appearance and convenient operation and maintenance.

Description

technical field [0001] The invention relates to a low-speed heavy-duty fiber braided compound self-lubricating liner performance testing machine. Background technique [0002] Self-lubricating spherical plain bearings have broken through the limitations of traditional spherical plain bearings. With many outstanding advantages such as self-lubricating, maintenance-free, small size, and light weight, they have attracted extensive attention from people in the industry at home and abroad. bigger. Especially in the field of national defense and aerospace, self-lubricating spherical plain bearings are paid more and more attention both domestically and internationally. The comprehensive performance of high-quality self-lubricating spherical plain bearings for national defense and aviation has become a measure of the flight performance of helicopters and fighter jets in various countries. One of the key indicators of performance, service performance and cost performance. [0003] ...

AI Technical Summary

Problems solved by technology

The quality, performance and quality of domestic fiber braided composite self-lubricating liners cannot fully meet the requirements of high-quality self-lubricating joint bearings for national defense and aviation in my country, and its test methods and conditions are seriously behind

In terms of the performance test of the fiber braided composite self-lubricating liner, at present, our country still stays on conventional test methods and general test methods. etc. are still blank
