SWC-CH Long Telescopic Welded Universal Coupling

The SWC-CH Long Telescopic Welded Universal Coupling is a high-performance mechanical transmission component, specially designed for applications requiring large angle transmission and axial displacement. It is widely used in heavy-duty and high-impact industrial environments. Its core advantage lies in combining the strength of a welded structure with the long telescopic compensation function, ensuring efficient and stable power transmission in complex working conditions.
The coupling features a modular design, with core components including a flange connection end, telescopic spline set, cross universal joint, welded body, and lubrication system. These components work in precise coordination to ensure efficient power transfer and excellent adaptability. Notably, the welded body design significantly improves the coupling's rigidity and torsional strength compared to traditional bolted connections. It also enhances sealing performance, effectively preventing connection loosening, and reducing the risk of equipment failure.
The long telescopic feature of the SWC-CH coupling is its standout characteristic. By precisely aligning the telescopic spline set, it can flexibly compensate for axial deviations caused by thermal expansion, installation errors, or dynamic displacement during operation, avoiding stress concentration and premature component failure. The telescopic structure uses an involute tooth profile with precise gap control, ensuring smooth axial extension while improving wear resistance and extending the service life.
The cross universal joint, which serves as the core power transmission component, is made from high-strength alloy steel and undergoes precision heat treatment and surface strengthening. This ensures stable torque transmission within a large angle deflection range. The angle compensation typically ranges from 15° to 25°, and when used in a double-stage series, the compensation capacity is further enhanced. This effectively resolves power transmission issues in cases of misalignment and large axis angle, ensuring stable and reliable performance during prolonged high-load operations.
