Common failures of couplings
Common failures of couplings
In the daily use of geared couplings, the coupling manufacturer will show you that the coupling often has the following failures: 1. The coupling has broken teeth. 2. The axial displacement of the coupling gear is relatively large, even unable to mesh. 3. The gear surface of the coupling is severely damaged. 4. Coupling butt...

Technical advantages of flexible diaphragm coupling
Technical advantages of flexible diaphragm coupling
1. Dry couplings, non-lubricated flexible diaphragm couplings rely on metal diaphragms to transmit torque and absorb deformation. There is no relative movement between components. Gear couplings are rigid movable couplings that rely on tooth surfaces. The relative slip between the two axes...

Coupling requirements and optimized design structure
Coupling requirements and optimized design structure
The torque transmission of the coupling is mainly to set the nominal torque requirement of the transmission system.When the torque transmission element is overloaded, the torque transmission element is separated from the two half couplings to realize the protection of the main transmission system at both ends.On the one hand, the coupling is a coupling...
