Welded Cardan Shaft

Welded cardan shaft is an important type of cross axis universal joint, which belongs to rigid movable joint. It fixedly connects the coupling components through welding, utilizing its unique mechanical characteristics to enable continuous rotation of the two shafts connected without being on the same axis or having an axis angle, and reliably transmitting torque and motion.

The characteristics of a welded cardan shaft are its large angular compensation capability, compact structure, and high transmission efficiency. The allowable angle between the two axes of welded universal joints with different structural forms varies, generally between 5 ° -45 °. According to specific structure and usage requirements, welded universal joints can be divided into various models, including SWC-CH type long telescopic welding, SWC-BH type standard telescopic welding, SWC-WH type non telescopic welding, etc.

Welded universal joints are widely used in industries such as metallurgy, lifting, engineering transportation, mining, petroleum, shipbuilding, coal, rubber, paper machinery, etc., especially suitable for heavy machinery equipment and occasions that require high torque transmission. Its reliable performance and flexible adaptability make it an indispensable and important component of modern industrial transmission systems.

The core structure of a welded universal joint coupling mainly consists of fork head components, cross shaft assemblies, and connecting components. Compared with ordinary universal couplings, its uniqueness lies in the use of welding to fix key components instead of bolted connections. The integral fork head design is a typical feature of welded universal joints, which connects the fork head to other components through welding processes, significantly improving overall strength and reliability. In terms of bearing fixation methods, welded designs usually do not require bolts, simplifying the structure and reducing potential failure points.
