Abstract
The utility model relates to a kind of static and dynamic sealing waterproof construction of bearing, comprise by the bearing of bearing holder device in roll shaft end, the lateral means of bearing has bearing outer ring gland, the outer side surface of bearing outer ring gland is with central channel and the labyrinth annular groove being positioned at side, central channel outer ring, and in described central channel, device has the outside framework oil seal being placed on roll shaft outer wall; The side of bearing outer ring gland is provided with the waterproof ring being installed on roll shaft outer wall, and the side of waterproof ring is with the labyrinth bulge loop with described labyrinth ring slot fit, and waterproof ring and roll shaft interference fit, the width of labyrinth annular groove is greater than the width of labyrinth bulge loop.The utility model adopts outside framework oil seal to realize the dust-proof grease proofing of bearing and waterproof ring and seals relative to the static waterproof sealing of roll shaft and the dynamic water-proof between waterproof ring with bearing outer ring gland and combine, effectively prevent water from immersing in bearing, improve working life and the operation stability of bearing, decrease maintenance and the after cost of bearing.
Description
Technical field
The utility model relates to the technical field of sealing technology of bearing, particularly relates to the waterproof sealing technology of bearing.
Background technique
At present, the dust sealing technology for bearing is quite ripe, generally adopts dust-proof seal ring, but for the waterproof aspect of bearing, dust-proof seal ring cannot realize waterproof, and the working life of bearing is short, uses water-sealed bearing then its high cost.
Model utility content
The shortcoming that the applicant exists for above-mentioned prior art, carries out studying and designing, provides a kind of static and dynamic sealing waterproof construction of bearing, which raises bearing working life and operation stability, reduces bearing maintenance and after sales service expense.
The technological scheme that the utility model adopts is as follows:
A kind of static and dynamic sealing waterproof construction of bearing, comprise by the bearing of bearing holder device in roll shaft end, the lateral means of bearing has bearing outer ring gland, the outer side surface of bearing outer ring gland is with central channel and the labyrinth annular groove being positioned at side, central channel outer ring, and in described central channel, device has the outside framework oil seal being placed on roll shaft outer wall; The side of bearing outer ring gland is provided with the waterproof ring being installed on roll shaft outer wall, and the side of waterproof ring is with the labyrinth bulge loop with described labyrinth ring slot fit, and waterproof ring and roll shaft interference fit, the width of labyrinth annular groove is greater than the width of labyrinth bulge loop.
Further improvement as technique scheme:
The cross section of described labyrinth annular groove and labyrinth bulge loop is triangular structure.
Described labyrinth annular groove and labyrinth bulge loop include two circles.
The beneficial effects of the utility model are as follows:
The utility model adopts outside framework oil seal to realize the dust-proof grease proofing of bearing and waterproof ring and seals relative to the static waterproof sealing of roll shaft and the dynamic water-proof between waterproof ring with bearing outer ring gland and combine, effectively prevent water from immersing in bearing, improve working life and the operation stability of bearing, decrease maintenance and the after cost of bearing.
Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present utility model.
Fig. 2 is the assembly structure figure of bearing outer ring gland and waterproof ring.
In figure: 1, bearing support; 2, bearing; 3, bearing outer ring gland; 31, central channel; 32, labyrinth annular groove; 4, outside framework oil seal; 5, waterproof ring; 51, labyrinth bulge loop; 6, roll shaft.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, the static and dynamic sealing waterproof construction of the bearing of the present embodiment, comprise the bearing 2 being installed on roll shaft 6 end by bearing support 1, the lateral means of bearing 2 has bearing outer ring gland 3, the outer side surface of bearing outer ring gland 3 is with central channel 31 and the labyrinth annular groove 32 being positioned at side, central channel 31 outer ring, and in central channel 31, device has the outside framework oil seal 4 being placed on roll shaft 6 outer wall; The side of bearing outer ring gland 3 is provided with the waterproof ring 5 being installed on roll shaft 6 outer wall, the side of waterproof ring 5 with the labyrinth bulge loop 51 coordinated with labyrinth annular groove 32, waterproof ring 5 and roll shaft 6 interference fit, waterproof ring 5 and roll shaft 6 keep static sealing; The width of labyrinth annular groove 32 is greater than the width of labyrinth bulge loop 51, and to guarantee that reaching the two can realize contact friction, namely the relative bearing outer ring gland 3 of waterproof ring 5 keeps dynamic seal (packing).
The cross section of labyrinth annular groove 32 and labyrinth bulge loop 51 is triangular structure, and labyrinth annular groove 32 and labyrinth bulge loop 51 include two circles.
Waterproof ring in the utility model is supported by corrosion-resistant material.
The utility model adopts outside framework oil seal to realize the dust-proof grease proofing of bearing and waterproof ring and seals relative to the static waterproof sealing of roll shaft and the dynamic water-proof between waterproof ring with bearing outer ring gland and combine, effectively prevent water from immersing in bearing, improve working life and the operation stability of bearing, decrease maintenance and the after cost of bearing.
Above illustrated embodiment is better embodiment of the present utility model, only be used for conveniently the utility model being described, not any pro forma restriction is done to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristics, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristics content of the present utility model, all still belong in the scope of the utility model technical characteristics.
