According to the invention, various low and high friction pairs in a contact zone can be tested online for frictional wear, energy consumption, vibration and material behaviors under the different loads, rotating speeds and lubrication conditions, and transmission parts and systems can be conducted with friction and transmission process experiments; when testing data is gathered, parts and systems to be tested can be analyzed for the following situations such as frictional wear, power consumption, stress and the service behaviors of transmission pairs, so that the behavior features, variation rules and failure mechanisms of research objects in the operating process can be obtained.

Description

technical field [0001] The invention belongs to a friction wear and transmission performance testing device, in particular to a multipurpose mechanical part transmission and friction test bench. Background technique [0002] The rotating transmission pair mechanism refers to the transmission mechanism for the purpose of transmitting torque, such as gears, cylindrical rollers, tapered rollers, special-shaped rollers, rolling friction wheels, belt transmission pairs, and sprocket transmission pairs. In order to improve the performance of the mechanism, it is necessary to use a test bench with a rotating transmission pair mechanism to study the surface morphology, contact form, and shape changes of the material. Tribological research is not limited to rotating pairs. The same experimental platform can have multiple functions. Different experiments can be carried out without changing the position of most of the structure of the machine, which is conducive to the analysis and com...

AI Technical Summary

Problems solved by technology

[0003] Existing test benches for rotary transmission mechanisms are generally designed specifically for performance testing of certain parameters of a certain mechanism. The type of test object is often relatively single, with fewer detection parameters and a relatively narrow measurement range.

For example, CN102261992A discloses a spiral bevel gear coupling transmission test bench structure with variable stiffness elastic support, which can only carry out spiral bevel gear coupling transmission experiments, and an overly long driving shaft will affect the transmission accuracy

For example, the rolling friction and wear tester disclosed in CN102419291A can only carry out rolling friction test, and the testing machine cannot guarantee the parallelism of the two main shafts during the loading process of force.
