SWC-DH Short Telescopic Welded Universal Coupling

The SWC-DH Short Telescopic Welded Universal Coupling is a core component of heavy-duty transmission systems, featuring an innovative short telescopic design. It offers axial compensation ranging from 50-100mm, with an overall length reduced by 30% compared to the standard model. This coupling is particularly suitable for applications where installation space is limited, efficiently solving the axial displacement compensation and transmission needs, ensuring stable operation of equipment under heavy loads.
The core structure of this model consists of welded yokes, cross assembly, telescopic sleeve, bearing components, and a lubrication sealing system. Unlike traditional flange-connected couplings, the SWC-DH coupling adopts an integrated welded yoke design, simplifying the structure, reducing the number of components, and eliminating the stress concentration risks associated with bolt connections. This improves structural strength and operational reliability, reduces overall weight, and lowers energy consumption.
The short telescopic design is the highlight of the SWC-DH model. By precisely matching the telescopic sleeve with the spline, it ensures flexible compensation for axial displacement, with compensation ranging up to 5-8% of the total length. This design effectively addresses axial displacement caused by thermal expansion, vibration, or installation deviations, preventing transmission system jamming or damage. The telescopic sleeve is designed with precision guidance and undergoes special surface treatment to reduce the friction coefficient, ensuring smooth operation while extending service life.
