The Function of Cross Universal Coupling

Cross universal coupling is a mechanical component used to connect two shafts in different mechanisms to rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the effect of buffering vibration and improving the dynamic performance of the shaft system. The cross-joint universal coupling consists of two halves that are connected to the driving shaft and the driven shaft respectively.

The transmission mode of the universal cardan shaft adopts sliding transmission and rolling transmission. In the cardan driveshaft, the universal joint bears large torque and alternating load during operation. If it is damaged, the damage will mainly be in the form of wear or indentation of the cross journal and the needle roller bearing inside. Serious It may peel off, so maintenance is very important for the universal joint shaft.
