Characteristics Of Universal Shaft Coupling

The universal shaft coupling as a key component in mechanical transmission systems, has the following significant characteristics:

1. Large angle compensation capability
   By designing structures such as cross shafts and ball cages, an angle of 5 ° -45 ° between the two axis lines is allowed, which can effectively compensate for installation deviations or angular, radial, and axial displacements generated during operation. For example, the shaft offset caused by thermal deformation of the rolling mill in metallurgical equipment can be adaptively adjusted through universal couplings.

2. Non concentric shaft transmission
   The unique multi-directional articulated structure (such as a cross axis+bearing combination) enables power transmission between non collinear axes, making it suitable for space limited or dynamic motion scenarios such as excavator slewing mechanisms.

3. Efficient transmission
   The transmission efficiency can reach 98% -99.8%, especially suitable for high-power and heavy-duty working conditions. In heavy mining machinery, its torque transmission capacity is more than 30% higher than other couplings of the same size.

4. Dynamic adaptability
   Vibration reduction and buffering: Elastic components can absorb impact loads, reduce torsional vibrations, and protect downstream equipment.
   High speed stability: Models that have undergone dynamic balancing treatment (such as SWC-BH type) can operate smoothly at speeds above 3000rpm and are used for connecting the main shaft of wind turbines.

5. Compact design
   The integral fork head and modular structure (such as SWP split) save installation space.

The cardan shaft coupling, through its unique structural design and material technology, achieves efficient and reliable power transmission under complex working conditions, and is an indispensable core transmission component of modern industrial equipment.
