Title:
THRUST BEARING TESTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/221291
Kind Code:
A1
Abstract:
A thrust bearing testing machine, relating to the technical field of test equipment. A main body structure comprises a rack (1) consisting of an upper table top (101), a lower table top (102), and vertical columns (103) connecting the upper table top (101) and the lower table top (102), an optical system (2) and a rotary system (3) provided on the upper table top (101), a loading system (4) provided on the lower table top (102), and a main shaft system (5) passing through the upper table top (101) to be connected to the rotary system (3) and the loading system (4), such that the thickness of a lubricating oil film can be collected under a high-speed working condition in a state that the movement of a retainer (200) is limited, the friction torque between rolling bodies (100) and a glass disc (301) can be measured in a state that the movement of the retainer (200) is not limited, and a conventional weight loading mode is abandoned; the main shaft system (5) is pressed upwards by means of a jack (401), such that the large-range interference between the rolling bodies (100) and the glass disc (301) is realized, so as to obtain the film thickness and the friction torque under different operating parameters; the present invention is simple in structure, convenient to operate, accurate in measurement data, and high in measurement result repeatability, and facilitates quantitative analysis and research on higher pair contact tribological characteristics.
