Cardan Shaft Couplings

Cardan Shaft Coupling is a mechanism that utilizes the characteristics of its mechanism to enable continuous rotation of the two shafts connected without being on the same axis and with an angle between the axes, and to reliably transmit torque and motion. It has a large angular compensation capability, compact structure, and high transmission efficiency. There are various structural types of Cardan Shaft Couplings, such as cross shaft type, ball cage type, ball fork type, convex block type, ball pin type, ball joint type, ball joint plunger type, three pin type, trident rod type, three ball pin type, hinge rod type, etc. Among them, the most commonly used is the cross axis type, followed by the cage type. The core component of the cross axis Cardan Shaft Coupling is the cross axis, which allows the two shafts to rotate continuously at equal angular velocities within a large range of angles. The ball cage Cardan Shaft Coupling achieves two axis transmission through components such as the outer ring of the ball cage, the inner ring of the star shape, the cage, and the transmission steel ball. It is suitable for working conditions with large inclination angles and limited radial dimensions.

According to the magnitude of the transmitted torque, Cardan Shaft Couplings can be classified as heavy, medium, light, and small. Different models of Cardan Shaft Couplings are suitable for different mechanical transmission systems. Cardan Shaft Couplings are widely used in metallurgy, heavy machinery, petrochemicals, engineering machinery, rail transportation, agricultural machinery, industrial machinery and other fields. For example, in steel rolling machinery, Cardan Shaft Couplings are used to connect rollers and transmission systems, achieving reliable torque transmission; In heavy transportation equipment, it is used to connect the wheels and transmission shaft, ensuring that the vehicle can travel smoothly in various road conditions.

Cardan Shaft Couplings have significant angular compensation capabilities and can adapt to changes in the angle between two shafts. Compact structure, small footprint, easy to install and maintain. The transmission efficiency of Cardan Shaft Couplings is high, which can reduce energy loss and improve the overall performance of mechanical transmission systems. Using high-quality materials and advanced manufacturing processes, the Cardan Shaft Coupling has high reliability and durability.

When selecting a Cardan Shaft Coupling, factors such as the magnitude of the transmitted torque, the speed of the shaft, and the magnitude and direction of the relative displacement between the two shafts need to be considered. At the same time, it is necessary to refer to the characteristics of various types of couplings and choose a suitable type of coupling. For the Cardan Shaft Couplings that have already been selected, regular maintenance and upkeep are required. For example, regular lubrication can extend its service life; When disassembling and reinstalling, it is necessary to pay attention to adjusting the position of the cross axis to balance wear and tear; In addition, it is necessary to regularly check the wear of the coupling and replace damaged components in a timely manner.
