Working Principle Of Cross Axis Universal Coupling

The cross axis universal coupling consists of two fork joints (universal coupling forks), a cross axis, and needle roller bearings.

Core Principle

  1. Power transmission path: The driving shaft drives the cross shaft to rotate through the universal coupling fork, and the other end of the cross shaft drives the driven shaft universal coupling fork to rotate.

  2. Angle compensation capability: The four necks of the cross shaft are connected to two universal coupling forks through needle roller bearings, allowing power transmission between the two shafts within a range of 5 ° -45 ° angles.

Double cross shaft couplings are commonly used in industry to counteract speed fluctuations and ensure consistent input/output shaft speeds through specific installation methods.

The SWC type adopts an integral fork head to enhance rigidity and is suitable for heavy-duty scenarios with a torque of up to 10000KN · m; SWP type split fork is easy to maintain and is commonly used in metallurgical equipment.

Typical applications

  1. Automotive industry: Connecting the transmission and drive axle to adapt to suspension motion during driving.

  2. Metallurgical machinery: The main drive shaft of the rolling mill compensates for the axis deviation caused by the lifting of the rolling mill rolls.

  3. Construction machinery: The slewing mechanism of the crane transmits power to the walking device.

The cross axis universal coupling achieves non collinear shaft power transmission through a unique hinge structure, and its dual design solves the problem of speed fluctuations. The advancement of materials and bearing technology further expands its application boundaries in heavy-duty and high-speed fields.
