Background

The coupling is a mechanical component which rotates two shafts or a shaft and a rotating part together in the process of transmitting motion and power and transmits motion and torque.

The squeezer and the reducing gear box are generally connected by adopting a traditional rigid or square shaft coupler in the current sugar squeezing field, when the squeezing quantity fluctuation of the squeezer exceeds the assembly data of the outlet and the inlet of the squeezer, the lifting of the top roller can be increased, in the lifting process, the radial force formed by the coaxiality deviation of the output shaft of the reducing gear box and the top roller is offset by relying on the bearing of the reducing gear box and the bolt of the box cover, the top roller offsets the stress of the coaxial deviation by relying on the oil pressure of an oil pressure head, particularly, the coupler and the reducer of the squeezer are easy to damage when the load suddenly changes, and great equipment hidden. The hidden danger can cause the breakage of the western shaft diameter of the top roller of the squeezer, the cracking of the positioning boss of the east bearing bush, the shifting of the reduction gearbox of the squeezer to the motor direction caused by the back jacking of the undersize compensation range of the relative displacement of the coupler, the outward inclination of the rack on the east side of the squeezer and the like, so that the accidents are easily caused. Especially in the season of squeezing, the yield of the squeezed sugar is large, and the traditional coupling is difficult to avoid the problems, so that the pressure of a sugar mill in the maintenance process of equipment in the season of squeezing is huge, and the productivity is influenced. The steel wire rope flexible coupling has great advantages in the field of sugar pressing, and can effectively protect the application advantages of the speed reducer, the main shaft of the squeezer and the bearing stability.

Although the rope is adjusted to be at the optimal stress angle by adjusting the length of the floating block, the rope is only temporarily at the optimal stress angle, and the rope can be stressed and deformed after being subjected to impact force in the long-term transmission process, so that the situation that the whole rope is locally tightened and loosened on the coupler is caused, and the length of the whole rope is basically fixed on the coupler, therefore, the rope is easily subjected to fatigue pressure damage due to the fact that the rope and the supporting block are in hard contact because the rope directly acts on the coupler or the supporting block of the floating block, the strength is gradually reduced, and the service life of the rope is finally influenced.
