Coupling testing device

Abstract

The invention provides a coupling testing device. The coupling testing device comprises a first tool and a second tool, wherein the first tool and the second tool are fixedly connected to two ends of a coupling respectively; the first tool comprises a first fixing rod and a first connecting piece; the first fixing rod is inserted in a first end of the coupling; the first connecting piece is connected with the first fixing rod and a torque spanner; the second tool comprises a second fixing rod and a second connecting piece; the second fixing rod is inserted in a second end of the coupling; the second connecting piece is connected with the second fixing rod and is fixedly connected with a bench clamp; and each of the first fixing rod and the second fixing rod is provided with a clamping column which can be in clamping connection with a corresponding fixing hole of the coupling. The clamping columns are in clamping connection with the fixing holes, so that the first fixing rod and the second fixing rod are fixed with the coupling. Compared with a coupling testing device of fixing a coupling by using screws and bolts in the prior art, the coupling testing device has the advantages that fixation and disassembly of the coupling are simplified, so that testing on the coupling is simplified, and the testing efficiency of the coupling is improved.

Description

technical field [0001] The invention relates to the technical field of shaft coupling testing, and more specifically, relates to a shaft coupling testing device. Background technique [0002] Couplings are mechanical parts used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In order to ensure normal transmission, it is necessary to test the coupling, usually the torque test is mainly performed on the rubber part of the coupling. [0003] At present, there are threaded holes at both ends of the coupling, rubber in the middle of the coupling, and fixing holes on the side walls at both ends of the coupling. Bolts and screws are usually used to fix the coupling. The fixing method of the coupling is as follows: insert the first bolt into the coupling from one end of the coupling, and then use the first screw to pass through the fixing hole at the end from the outside and insert the first bolt into the couplin...

AI Technical Summary

Problems solved by technology

[0004] Before each test of the coupling, the first screw and the second screw need to be manually tightened, and the first screw and the second screw need to be manually loosened after the test, which makes the test more cumbersome and makes the test efficiency lower

[0005] In addition, each test requires manual tightening and loosening of the first screw and the second screw, resulting in more workload for the staff and greater labor intensity

[0006] In addition, during the test, the threads at the ends of the first bolt and the second bolt are easily damaged, and the first bolt, the second bolt, the first screw and the second screw need to be replaced regularly to ensure a more accurate alignment of the coupling. testing, resulting in higher testing costs
