The utility model aims to overcome the not enough of above-mentioned prior art, provide the fan transmission shaft of vapour overflow dyeing machine, long service life, intensity is high, and transmission power stability is good.
For realizing above-mentioned purpose, the utility model provides a fan transmission shaft of vapour overflow dyeing machine, including main shaft, axle sleeve and movable sleeve, the both ends of main shaft are equipped with the bearing seal, be equipped with the keyway on the bearing seal, the one end cover of main shaft is equipped with a plurality of axle sleeves, the axle sleeve is big axle sleeve and little axle sleeve respectively, the one end at the main shaft is established to little axle sleeve cover, big axle sleeve cover is established on little axle sleeve, is equipped with the step between big axle sleeve and the little axle sleeve, another pot head of main shaft is equipped with the movable sleeve, the movable sleeve can be at round trip movement between axle sleeve and bearing seal, be equipped with keyway two on the movable sleeve.
The spindle can be fixed by arranging the spindle sleeve, the movable sleeve is arranged and arranged on the spindle, and the movable sleeve is fixedly connected with the impeller spindle through the key groove II, so that friction between the spindle and the impeller spindle is reduced, the service life of the spindle is prolonged, and the cost is reduced.
Preferably, a plurality of holes are formed in the movable sleeve, and leakage in the machine can be discharged through the holes, so that the bearing is prevented from being damaged, and the operation failure frequency of the machine is reduced.
Preferably, the holes are circular or square.
Preferably, a gland is arranged on the step, and the tightness and the stability of connection between the large bearing and the small bearing are improved by arranging the gland.
Preferably, the main shaft and the shaft seal are integrally formed, the small shaft sleeve is connected with the main shaft through a bolt and a gasket, the integrally formed main shaft and the shaft seal are good in stability and high in strength, the bolt connection of the small shaft sleeve is detachable, and the service life of the whole body is prolonged.
The utility model has the advantages that: the utility model has the advantages that the movable sleeve is arranged to protect the main shaft, so that the friction force between the main shaft and the impeller main shaft is reduced, the service life of the main shaft is prolonged, and the use cost is reduced; the small holes arranged on the movable sleeve can discharge the leaked liquid in the machine, thereby reducing the operation failure of the machine; the main shaft and the shaft seal that the integral type set up to and detachable axle sleeve have improved holistic joint strength, have prolonged life.
