SWP-B Universal Joint Shaft Coupling

 

SWP-B Universal Joint Shaft Coupling


文章附图

SWP-B Universal Joint Shaft Coupling


The SWP-B universal joint shaft coupling is a cross-shaft type universal joint coupling featuring a telescopic (lengadjustable) design. It is widely used in various types of heavy machinery.


The SWP-B universal joint shaft is mainly composed of two universal joint yokes, a cross shaft, bearing housings, and other components. It boasts a compact structure and high transmission efficiency, enabling it to connect two transmission shaft systems with different axes, thereby achieving angle compensation and axis offset adjustment. Meanwhile, this coupling is also equipped with a telescopic function, allowing it to adapt to axial displacements within a certain range.


The SWP-B coupling is suitable for rolling machinery, lifting and transportation machinery, and other heavy machinery that requires connecting two transmission shaft systems with different axes.

When installing the SWP-B cross-shaft universal joint coupling, it is necessary to ensure the cleanliness of the flange joint surface and avoid impurities such as anti-rust grease. At the same time, the flange connection bolts must be tightened according to the specified tightening torque to ensure the stability and reliability of the coupling.

During the operation of the SWP-B cross-shaft universal joint coupling, long-term overloading should be avoided to prevent operational accidents.


During working operation, it is essential to frequently check the universal joint coupling for abnormal radial runout, bearing overheating, and other phenomena. Once such phenomena are detected, the machine should be shut down promptly for inspection and maintenance.


The SWP-B cross-shaft type universal joint coupling is a heavy machinery transmission component with a compact structure, high transmission efficiency, and a wide range of applications. During installation and maintenance, operations must be carried out strictly in accordance with regulations to ensure its normal operation and extend its service life.

Key Terminology Explanation (for clarity in engineering context)

swp universal joint shaft coupling.png

  • Universal joint coupling: A mechanical component used to transmit torque between two shafts that are not collinear (have misaligned axes).


  • Cross-shaft type: A common design of universal joint where a cross-shaped shaft (cross shaft) connects two yokes, enabling angular movement.


  • Telescopic function: The ability of the coupling to adjust its length, accommodating axial (along the shaft) displacements between connected shafts.


  • Tightening torque: The specific rotational force required to fasten bolts, ensuring secure assembly without damaging components (critical for mechanical stability).
