Slip Differential Shaft
It is a device that realizes constant tension control of multiple rolls of materials through a slip differential shaft. Slip Differential Shaft, also known as a friction shaft, uses the slip characteristics of the slip differential shaft to automatically adjust the tension of the rolls, ensuring that the multiple rolls of materials maintain a constant tension during the winding or unwinding process to avoid uneven tension or uneven end surfaces. It is particularly suitable for slitting multiple strips of materials with uneven thickness, ensuring uniform tension for each roll of material, thereby improving product quality.
The Slip Differential Shaft consists of a shaft core, a friction component, and multiple sets of differential rings, each of which can slip independently. The size of the friction force is adjusted by the size of the air pressure filled. By controlling the central air pressure or the pressure transmitted from the side, the tension of each coil from the inner diameter to the outer diameter can be kept constant and uniform.
In equipment such as slitting machines, due to the thickness error at each point of the entire material, the diameter of each coil will produce a large accumulated error during the strip winding process, resulting in a speed tension difference between the coaxial coils, uneven tightness, uneven end faces, and some coils are stretched and deformed due to excessive tension. The differential ring of the differential shaft of the air shaft accessory can slip with a certain slip torque, which just compensates for the speed difference, accurately controls the tension of each roll of material, ensures that the material is tensioned, realizes constant tension winding and unwinding, and makes the winding end face neat. The running speed of the slitting machine can be greatly improved, thereby improving the overall production efficiency and reducing costs.
