Universal Joint Shaft Couplings

Universal joint shaft coupling is a mechanical component that achieves non collinear shaft transmission through structures such as cross shafts and ball cages.

Core Features

1. Large angle compensation capability: allows the angle between the two axis lines to vary within the range of 5 ° -45 °, such as cross axis compensation angle of over 25 ° and cage type compensation angle of up to 45 °.
   

2. Efficient transmission: Made of alloy steel or composite materials (such as 42CrMo, 45 forged steel), the transmission efficiency exceeds 98%, and the torque transmission capacity of some heavy-duty models can reach 1250kN · m.
   

3. Modular design: including SWC (welded type), SWP (split bearing seat type) and other series, supporting expansion spline structure to compensate for axial displacement (such as SWC350 type with an expansion of 130mm).

Mainstream types and application scenarios

1. Cross axis type (SWC series)
   Heavy duty transmission: used for steel rolling mills and lifting machinery, with a nominal torque of 16-1250kN · m and strong impact resistance.
   Automotive industry: Suitable for truck drive shafts with flange design.

2. Cage style
   Precision field: Car drive shafts use constant velocity universal joints to eliminate speed fluctuations.

3. Micro universal joint (WSD series)
   Light industry equipment: small couplings with an outer diameter of 20mm, suitable for multi axis linkage systems such as drilling and tapping machines.

The universal joint shaft coupling is developing towards high precision and integration, becoming a key transmission component of intelligent manufacturing equipment.
