Universal coupling

The universal coupling utilizes the characteristics of its mechanism to make the two shafts not on the same axis, and when there is an angle between the axes, it can realize the continuous rotation of the connected two shafts and transmit torque and motion simultaneously.The characteristics of the universal coupling are: its structure has a large angular compensation capability, a compact structure, and a transmission.The angle between the two axes of universal joints of different structures is different, generally between 5°-45°.The choice of universal coupling mainly considers the speed of the required transmission shaft, the size of the load, the installation accuracy of the two connected parts, the stability of rotation, the price, etc., refer to the characteristics of various couplings, choose one Suitable coupling type.

The cross-shaft universal coupling is a large universal coupling, and the bearing is a vulnerable part of the cross-shaft universal coupling.The main difference between several large cross-shaft universal joints is the change of the bearing seat and the cross fork to form different structural forms.For the synchronization of the main and driven shafts, the double-connected form is adopted in practical applications. The double-connected connection method is nothing more than welding or flange connection by bolts. The change in the length of the middle can take many forms.

The cross head components of the cross shaft universal coupling have the following forms: SWC type integral fork cross shaft universal coupling (JB/T 5513-2006), SWP type partial bearing seat cross shaft universal coupling Shaft (JB/T 3241-2005), SWZ type integral bearing seat cross shaft universal coupling (JB/T 3242-1993), WS type small double cross shaft universal coupling (JB/T 5901 -1991), WSD type small single cross shaft universal coupling (JB/T 5901-1991), SWP type cross shaft universal coupling with cross bag (JB/T 7341.1-2005), WGC type cross shaft Cross bag for universal joint (JB/T 7341.2-2006).The above heavy and small cross-shaft universal couplings are all universal. Different models in the automotive industry have their own cross-shaft universal couplings or other types of universal couplings.For example, a car uses a ball cage universal coupling.In addition, agricultural machinery, industrial machinery and other sports machinery products also have universal couplings, and cross-shaft universal couplings are mostly used for lifting.
