The purpose of this utility model is to provide a kind of drive shaft sealing structure of nano coating screw vacuum spraying equipment, comprise transmission shaft, outward flange, stuffing box bearing, described transmission shaft surface is provided with several hollow slots, in the hollow slot at two ends, be provided with O RunddichtringO, in middle hollow slot, be provided with y-type seal ring, described adjacent y-type seal ring direction is relative, described stuffing box bearing is positioned at the outside, two ends of transmission shaft, transmission shaft and outward flange are tightly connected, described stuffing box bearing arranged outside has dust cover, between dust cover and transmission shaft, is provided with dust ring.
Further improvement of the utility model is: position corresponding with O RunddichtringO on described outward flange is also provided with seal groove, and O RunddichtringO is embedded between hollow slot and seal groove.O RunddichtringO is embedded between transmission shaft and outward flange, after O RunddichtringO packs into, can effectively improve the good seal between the two.
Further improvement of the utility model is: between the y-type seal ring of two of described centres, be provided with guidance tape, described guidance tape is positioned at the groove being opened on transmission shaft, setting up of guidance tape, active force to seal ring in the time of can alleviating transmission shaft action, when reducing the wearing and tearing of seal ring, can seal transmission shaft and outward flange, improve the motive sealing performance of the two.
Further improvement of the utility model is: between the afterbody of described y-type seal ring and hollow slot, be provided with back-up ring.For y-type seal ring is close in hollow slot, ensure the seal action of y-type seal ring.
The beneficial effects of the utility model: by offer hollow slot on transmission shaft, seal ring is located in hollow slot, ensure the barycentre steadiness of transmission shaft, make transmission shaft operating state lower seal can be stressed evenly, can ensure the sealing of transmission shaft and outward flange inwall, the poor sealing of avoiding indivedual ring wears seriously to cause, by y-type seal ring being set by centre, the multi-layer sealed circle body that two ends arrange the formation of O RunddichtringO is, y-type seal ring can bear larger pressure, resistance is little, the sealing surface of O RunddichtringO is larger, the combination of the two can ensure that seal ring system has stronger anti-pressure ability, can ensure that again seal ring system has wider sealing surface, thereby can ensure the motive sealing between transmission shaft and outward flange, can also reduce the resistance of transmission shaft in movement process, the wearing and tearing of minimizing to seal ring, improve transmission efficiency, improve the working life of seal ring, simultaneously by dust cover and dust ring are set, when preventing that seal shaft from bearing dirt, can ensure that the operation of transmission shaft is smooth and easy, resistance is little, reduces the wearing and tearing to seal ring, further strengthens the sealability of transmission shaft.
The utility model is simple in structure, and the sealability in the time of can effectively improving transmission shaft action ensures that the stressed of seal ring evenly reduces the stressed of seal ring, reduces the rate of depreciation of seal ring, thereby improved greatly the motive sealing performance of transmission shaft.
