Description

Technical Field

[0001] The utility model relates to the technical field of test and detection equipment, and more specifically to a loading running-in test bench. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads, playing the role of overload protection. During the production process of couplings, performance tests are often required on a loading and running-in test bench, and they can only be put into use after passing the test.

[0003] Based on the above, the inventors found that most of the existing loading and running-in test benches have the problems of inconvenient adjustment and poor applicability, and are unable to perform three-dimensional spatial movement. They are usually only suitable for experiments on a single coupling. Couplings of different sizes cannot be connected to the loading mechanism and the driving mechanism, and running-in experiments on multiple couplings cannot be realized. Therefore, in view of this, the existing structure is studied and improved, and a loading and running-in test bench is provided, in order to achieve the purpose of having more practical value.
