Description:

The coupling is mainly connected with the shaft of the motor, the reducer and the working machine, the shaft hole type, connection type and size mainly depend on the type and size of the connected shaft, product designers are generally designed according to the cylindrical and conical shaft extension standard, we will share the diaphragm shaft hole and keyway for you.

The diaphragm coupling consists of at least one diaphragm and two bushings. The diaphragm is fastened to the bushing with pins generally without loosening or causing recoil between the diaphragm and the bushing. Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and both sides are connected to the shaft sleeve. The difference between single diaphragm coupling and double diaphragm coupling is the difference in the ability to handle various deviations, in view of the need for complex bending of the diaphragm, so the single diaphragm coupling is not suitable for eccentricity. The double diaphragm coupling can be bent in different directions at the same time to compensate for the eccentricity.

Applications:

Widely used in shafting transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission system, steam turbine, piston power mechanical transmission system, tracked vehicles, As well as the high-speed, high-power mechanical transmission system of the generator set, it has been widely used in high-speed transmission shafting after dynamic balance.

The assembly of diaphragm coupling is a relatively simple maintenance process in mechanical maintenance. In the coupling assembly, the key is to master the assembly of the wheel hub on the shaft, the alignment of the two shafts connected by the coupling, the inspection of parts and the assembly of the coupling according to the requirements of the drawing.

Coupling is a type of more complex transmission products, due to the different needs of different customers, we need to order the use of couplings according to our actual needs, to plan and integrate the type of coupling suitable for our use, so many types of couplings, we should go to how to distinguish the choice?

Coupling model type distinction:

Although there are many types of coupling models, from the perspective of coupling, the total number of types of coupling is rigid coupling and flexible coupling.

The so-called flexible coupling has the ability to compensate for the relative deviation of the two axes, which varies greatly with the model. Where the coaxiality of the two axes is not easy, flexible couplings should be selected. Among the coupling models, there are many types of flexible couplings. Commonly used types are elastic couplings, gear couplings, drum gear couplings and so on.
