Universal Joint Coupling Manufacturer In China

Rokee is a professional manufacturer of universal joint couplings from china, which are crucial connecting devices in the field of mechanical transmission. They can achieve reliable transmission of torque and rotational motion even when the two axis lines do not coincide and there is an angle between them.

The universal joint coupling uses its special hinge structure to position the power transmission point on the bisector of the angle between the two axes. This design principle is derived from the constant velocity meshing model of bevel gears, ensuring that even if there is an angle between the shafts, the driving shaft and the driven shaft can maintain the same instantaneous angular velocity. When the driving shaft rotates, the motion is transmitted to the driven shaft through the intermediate hinge mechanism, and the hinge components can freely adjust the angle to adapt to the misalignment of the axis.

The cross axis universal joint is a widely used universal joint coupling, which is mainly composed of two universal joint forks and a cross axis. The four journals of the cross shaft are equipped with needle roller bearings, and two universal joint forks are connected to the two pairs of journals of the cross shaft, forming a hinged structure that can rotate in multiple directions.

Structural subdivision: According to the different fork structures, the cross axis universal joint can be divided into several main forms:

1. SWC type: integral fork head structure with strong load-bearing capacity, suitable for heavy-duty equipment with a turning diameter of up to 1600mm;

2. SWP type: Split fork design, easy to install and maintain, commonly used for applications with a rotation diameter of less than 1200mm;

3. SWZ type: Integrated bearing seat structure with better sealing performance;

4. WS/WSD type: small cross shaft coupling, suitable for light load applications with limited space.

The correct selection and configuration of universal joint couplings are crucial for ensuring the reliable operation of mechanical transmission systems.
