Description

technical field [0001] The invention relates to a test structure of a shaft coupling, in particular to a static load test bench for a shaft coupling, which belongs to the field of mechanical transmission and is widely used for performance testing of various shaft couplings. Background technique [0002] With the continuous improvement of the mechanical industry and scientific research level, higher and higher requirements are put forward for the testing and testing methods of mechanical transmission products. Coupling is a common mechanical transmission equipment in modern industrial engineering. Static load test bench is an experimental device for coupling manufacturers or scientific research institutes to test parameters such as maximum torque and static torsional strength of couplings. [0003] Chinese patent 201110230470.3 discloses a test bench for testing shaft couplings. The characteristics of the test bench are: the coupling is driven to rotate by the power mechanism...

AI Technical Summary

Problems solved by technology

The advantage of this test bench is that the test bench is small in size and can realize multi-working condition testing. However, its disadvantage is that it cannot test heavy-duty and super-heavy-duty couplings, and when there is an inclination test, if the test object ( Coupling) has no axial displacement compensation function, and it is impossible to use this test bench for testing, that is, the types of couplings suitable for testing on this test bench are extremely limited

[0004] At present, there are no relevant reports on the structure of the super-heavy-duty coupling test bench at home and abroad.
