High presion Nishimura type differential slip shaft
Differential air shaft is mainly used for sub-section equipment that has high requirement on final products and fast speed.The differential ring on it can slip independently. Controlled by the tension system, let the compressed air which has a certain pressure come to axle core, so that it will produce friction torque between the friction parts and the slip ring, and realize constant tension coiling and it will help solve the unwinding problems and material damages caused by uneven thickness and tension of each roll material.
Description
Introduction
Known as slip shaft, differential shaft and friction shaft, it is mainly used as the winding shaft of the slitter and the unwinding shaft of special products. The friction force of the slip shaft is adjusted by the air pressure.
Differential air shaft is mainly used for sub-section equipment that has high requirement on final products and fast speed.The differential ring on it can slip independently. Controlled by the tension system, let the compressed air which has a certain pressure come to axle core, so that it will produce friction torque between the friction parts and the slip ring, and realize constant tension coiling and it will help solve the unwinding problems and material damages caused by uneven thickness and tension of each roll material.
Structure
Central air pressure differential shaft are made of core roll, differential ring, airbags, friction parts, sealing rings.

The Nishimura friction shafts is not only a vital part of the winder,such as drying machine, flexo printing machine, gravure machine, trademark printing machine, coating machine, leather machine, setting machine, embossing machine, slitting machine, die cutting machine, rewinding machine, paper tube machine, bag making machine, laminating machine, film blowing machine, foaming machine,embossing machine, paper machine, non-woven machine, cloth inspection machine, bronzing machine, battery device, and the like are all required. The quality of differential shaft is a good consideration for production.
