According to the structure of the intermediate shaft and the link form of the shaft fork, there are seven types of universal joint cross.

1. BH type, standard telescopic welded universal joint coupling
2. BF type, standard telescopic flange type universal coupling
3. DH type, short telescopic welded universal coupling
4. CH type, long telescopic welded universal coupling
5. WH type, non-telescopic welded universal coupling
6. WF type, without telescopic flange universal coupling
7. WD type, non-retractable short universal coupling

Cross shaft universal couplings can be widely used in metallurgy, lifting, factory transportation, mining, petroleum, shipbuilding, coal, rubber, paper machinery and other mechanical shafting transmission torque in the heavy machinery industry.

The main feature of the cross shaft universal joint is that it has a large angle compensation capability. The SWC type axis can be folded up to 1525, and the SWP type can reach about 10. Stable transportation, low noise, convenient assembly and disassembly and maintenance, and high transmission efficiency. Its transmission efficiency is 98-99.8%. It is used for high-power transmission with obvious energy saving effect and compact and reasonable structure. SWC type adopts integral fork head, which makes the carrying more reliable and large carrying capacity. Compared with the unique type of coupling with the same rotation diameter, the torque transmitted by it is greater. This has a more superior range of matching for mechanical equipment with restricted rotation diameter of 5-7126X 6H2577 universal joint.
