CY AIR DIFFERENTIAL SHAFT---Introduction to CY Air Differential Shaft

The side pressure air differential shaft is a high-performance device designed to control tension by transmitting axial pressure. It applies mechanical or pneumatic side pressure to the slip rings, generating friction force when the slip ring end faces slip and deflect during the rotation of the shaft core, thus producing a stable friction torque. The magnitude of the friction torque varies with the axial pressure, meeting different production process tension requirements.

There are two main types of side pressure differential shafts:

A. Mechanical Side Pressure Air Differential Shaft

This type uses compression springs at both ends to apply pressure to the slip rings. Its simple and stable structure makes it suitable for low-speed winding and rewinding processes. However, since the spring force is fixed, tension cannot be adjusted in real time, making it ideal for applications with relatively stable tension demands.

B. Pneumatic Side Pressure Air Differential Shaft

The pneumatic type uses a planar cylinder at the transmission end to press the slip rings. The air pressure can be adjusted in real time as needed, achieving precise control of constant tension or taper tension. This design greatly improves system flexibility and automation and is widely used in high-speed winding and production lines with strict tension control requirements.

Advantages and Disadvantages

The greatest advantage of the side pressure differential shaft is its ability to generate large torque and friction tension, making it suitable for high-tension winding applications. However, because the pressure is transmitted stepwise through the slip rings, there is a pressure reduction phenomenon between rings, which may affect uniformity to some extent. Proper design and adjustment can maximize its performance benefits.
