Cardan Shafts

Cardan Shaft is an important mechanical transmission component, which utilizes its structural characteristics to enable continuous rotation of the two shafts connected without being on the same axis and with an axis angle, and reliably transmit torque and motion. The biggest feature of Cardan Shaft is its large angular compensation ability, compact structure, and high transmission efficiency. The angle between the two axes of universal couplings of different structural types is not the same, generally between 5 ° -45 °.

There are various structural types of universal joint 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 cross Cardan Shaft consists of two fork shaped joints and a cross axis. The fork shaped joint is connected to the cross shaft through bearings and can rotate around the central axis of the cross shaft. This structure enables the Cardan Shaft Coupling to have a large angular compensation capability and can withstand large torques and axial forces. The ball cage Cardan Shaft is composed of an inner ball cage and an outer ball cage, which are connected by steel balls. This structure enables the ball cage Cardan Shaft to have better angular and axial compensation capabilities, making it suitable for high-speed and large angle transmission applications.

In practical applications, universal couplings are classified into heavy, medium, light, and small types based on the magnitude of the transmitted torque. A mechanical component used to connect two shafts (active shaft and passive shaft) in different mechanisms to rotate together and transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, vibration reduction, and improving the dynamic performance of the shaft system.

Different types of universal couplings are suitable for different transmission scenarios. For example, cross axis universal couplings are widely used in fields such as automobiles, agricultural machinery, and industrial machinery; The ball cage Cardan Shaft is more suitable for high-speed and large angle transmission applications, such as the drive shaft of a sedan.

When selecting a Universal Shaft coupling, factors such as the transmitted torque, shaft speed, relative position of the two shafts, and working environment need to be considered. At the same time, it is also necessary to pay attention to the quality and reliability of the Cardan Shaft, and choose products produced by legitimate manufacturers to ensure the stability and safety of the transmission.

When installing a Cardan Shaft, it is necessary to ensure that the axes of the two shafts are in the same plane and the angle does not exceed the specified range. At the same time, it is also necessary to pay attention to the lubrication and sealing of the bearings to prevent dust and moisture from entering the interior of the bearings and affecting their service life.

Universal couplings require regular maintenance and upkeep during use. This mainly includes checking the wear, lubrication, and sealing performance of the bearings. If severe bearing wear or decreased sealing performance is found, it should be replaced or repaired in a timely manner to ensure the stability and safety of the transmission.

Cardan Shaft as an important mechanical transmission component, has a wide range of applications in various fields. Understanding the structural characteristics, classification and usage, as well as the knowledge of selection and installation, is of great significance for the correct selection and maintenance of universal couplings.
