The SWC-WD Cardan Shaft, especially the SWC-WD non telescopic short cross shaft universal coupling, is a key component widely used in various mechanical transmission systems.

The SWC-WD Cardan Shaft is mainly used to connect two shafts (active shaft and passive shaft) in different mechanisms, so that they can rotate together and transmit torque. This type of coupling is particularly common in the main and auxiliary transmission of rolling mills, and is also widely used in lifting, mining, engineering, vehicle transportation, petroleum, shipbuilding, papermaking machinery, and other heavy machinery industries.

Main Features

Angle compensation capability: The SWC-WD Cardan Shaft has a large angle compensation capability, which allows it to maintain continuous rotation and reliably transmit torque and motion even when there is a certain angle between the two shafts. This characteristic makes it perform well in application scenarios that require dealing with complex transmission conditions.
Compact and reasonable structure: The coupling adopts an integral fork head design, which is compact and reasonable in structure. This not only improves its reliability for transportation, but also makes it more convenient for installation and maintenance.
Large bearing capacity: Compared with other types of couplings with the same rotational diameter, the SWC-WD Cardan Shaft transmits greater torque. This makes it have a wider range of compatibility in mechanical equipment with limited rotation diameter.
High transmission efficiency: Its transmission efficiency can reach 98%~99.8%, which can bring significant energy-saving effects in high-power transmission.
Smooth transportation and low noise: This coupling exhibits good stability and low noise characteristics during operation, which helps to improve the performance and user experience of the entire transmission system.

The SWC-WD Cardan Shaft has various structural types, such as cross shaft type, ball cage type, etc., among which the most commonly used is the cross shaft type. The angle between the two axes of universal couplings with different structural types is not the same, generally between ≤ 5 ° and 45 °. This flexibility enables it to adapt to various complex transmission conditions.

The SWC-WD Cardan Shaft plays an important role in mechanical transmission systems due to its unique advantages and wide application fields.
