Abstract
The utility model provides a fan bearing sealing device, belongs to the technical field of bearing sealing, and solves the problems of environmental pollution caused by leakage of lubricating oil in the conventional fan bearing box, downtime maintenance of a fan and the like. The fan bearing sealing device is characterized in that a bearing is arranged at a bearing installation position of a fan shaft through a bearing seat; the bearing seat comprises a base, an upper cover, and left and right end covers which are sleeved on the fan shaft; the base, the upper cover, the left and right end covers and the fan shaft enclose a closed bearing installation space; oil slingers which are used for preventing leakage of the lubricating oil are arranged between the bearing and the end covers; and the inner side of each end cover has a labyrinth structure that an arc-shaped oil return groove is formed on the inner side of each end cover, which is opposite to each oil slinger. The fan bearing sealing device is good in sealing effect and high in stability.
Description
Technical field
The utility model belongs to the bearing seal technical field, refers in particular to a kind of fan bearing seal arrangement.
Background technique
At present, what most fan bearing casees adopted is the sealing of felt formula, and the felt circle is installed on the two end cap of bearing housing; Utilize the felt circle to intercept the outside cascading water of lubricant oil, but the working life of felt is not long, follows the string behind the immersion oil easily; Cause seal failure; Lubricant oil rushes down outward environment has been caused pollution, and blower fan needs often to shut down maintenance simultaneously, has brought great inconvenience to use.
Summary of the invention
The purpose of the utility model provides good sealing effect, the good fan bearing seal arrangement of stability.
The purpose of the utility model is achieved in that the fan bearing seal arrangement; Through bearing support bearing is installed on the Bearing Installation position of blower fan axle; Described bearing support comprises base, loam cake and is sleeved on the left and right sides end cap on the blower fan axle; Base, loam cake, left and right sides end cap and blower fan axle surround the Bearing Installation space of a sealing; It is characterized in that: between bearing and end cap, be provided with and intercept the disc that rushes down outside the lubricant oil, the inboard of described end cap is a maze-type structure, and described maze-type structure is for to be provided with the arc oil-return groove at end cap and the corresponding inboard of said disc.
Change the bearing cover sealing part into labyrinth structure, and add disc at the main shaft place, the corresponding inboard of end cap and disc is provided with the arc oil-return groove, and both combinations can effectively seal, and efficiently solve the leakage of oil problem.
In above-mentioned fan bearing seal arrangement, described disc is an annular solid, and disc is extended with bulge loop towards the outer ring of the one side of end cap to the end cap side, and bulge loop extends to the upside of arc oil-return groove.
In above-mentioned fan bearing seal arrangement, Spielpassung between described arc oil-return groove and the bulge loop.
The utility model is compared the outstanding and beneficial technical effects of existing technology:
1, the end cap of the utility model adopts maze-type structure, and sealing effect is better.
2, the disc of the utility model cooperates with end cap, and disc is wrapped oil-return groove, and both combinations can effectively seal, and efficiently solves the leakage of oil problem of bearing housing.
3, the utility model is simple in structure, and stability is strong.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:
The fan bearing seal arrangement; Through bearing support bearing is installed on the Bearing Installation position of blower fan axle 4, described bearing support comprises base 1, loam cake 2 and is sleeved on the left and right sides end cap 3 on the blower fan axle 4 that base 1, loam cake 2, left and right sides end cap 3 and blower fan axle 4 surround the Bearing Installation space of a sealing; It is characterized in that: between bearing and end cap 3, be provided with and intercept the disc 5 that rushes down outside the lubricant oil; The inboard of described end cap 3 is a maze-type structure, and described maze-type structure changes bearing cover 3 sealing part into labyrinth structure for being provided with arc oil-return groove 6 in end cap 3 and said disc 5 corresponding inboards; And add disc 5 at blower fan axle 4 places; End cap 3 is provided with arc oil-return groove 6 with disc 5 corresponding inboards, and both combinations can effectively seal, and efficiently solve the leakage of oil problem.
At above-mentioned disc 5 are annular solids, and disc 5 is extended with bulge loop 7 towards the outer ring of the one side of end cap 3 to end cap 3 sides, and bulge loop 7 extends to the upside of arc oil-return groove 6.
Spielpassung between above-mentioned arc oil-return groove 6 and bulge loop 7.
The foregoing description is merely the preferred embodiment of the utility model, is not the protection domain that limits the utility model according to this, so: the equivalence that all structures according to the utility model, shape, principle are done changes, and all should be covered by within the protection domain of the utility model.
