Abstract
The invention discloses a sealing device of a fan bearing seat. The sealing device comprises a main shaft, wherein the main shaft is equipped with a bearing seat, a bearing, a bearing seat end cover and a gland in sequence; a felt is arranged on the bearing seat end cover; a first space is reversed between the bearing and the bearing seat end cover; an oil retainer and an oil catcher are arranged in the first space; the inner hole of the oil retainer is provided with a conical degree; a second space is reversed between the oil retainer and the oil catcher; and the first space is communicated with the second space. According to the invention, the whole space of the sealing device of the fan bearing seat is of a labyrinth shape; a great quantity of liquid oil threw out by the bearing can firstly be caught by the oil catcher, a small quantity of liquid oil flows past from the second space, however, the oil retainer can play the damping effect on the liquid oil and the felt can play the third sealing effect, so the sealing effect is greatly improved, the phenomenon of oil leakage of the fan bearing seat is avoided, the production cost is saved and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of seal arrangement, relate in particular to a kind of seal arrangement of bearing fan.
Background technique
Existing bearing fan seal arrangement reaches sealing effect through felt, shown in accompanying drawing 1, comprises main shaft 1, and bearing support 2, bearing 3, bearing cover 4 and gland 5 are installed on the main shaft 1 successively, and said bearing cover 4 is provided with felt 6.But, in use, find that the sealing effect of bearing fan seal arrangement is poor; Oil leakage phenomenon often takes place in bearing fan, has not only caused a large amount of wastes of lubricant oil, and often causes shutdown; Influenced manufacturing efficiency, analyzed its reason, be mainly following 2 points: 1, outside dust gets into felt; Make felt harden, thereby caused seal clearance to become big; 2, the high speed rotating of main shaft, the component wear on main shaft and the main shaft is serious, causes felt to damage.Therefore single pass through the bearing fan seal arrangement that felt reaches sealing effect and can not satisfy the production demand.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: the bearing fan seal arrangement that has proposed a kind of good sealing effect.
Technical solution of the present invention is achieved in that a kind of bearing fan seal arrangement; Comprise main shaft; Bearing support, bearing, bearing cover and gland are installed on the said main shaft successively; Said bearing cover is provided with felt, is provided with first space between said bearing and bearing cover, is provided with flinger ring in said first space and connects oil ring; The endoporus of said flinger ring has tapering; Said flinger ring and connect and leave second space between oil ring; Said first space communicates with second space.
Preferably, said flinger ring is near bearing; The said oil ring that connects is near bearing cover.
Preferably, be provided with fastening locknut in said first space; Said fastening locknut is near bearing.
Preferably, said flinger ring is near fastening locknut.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Bearing fan seal arrangement of the present invention, owing to be provided with flinger ring in first space and connect oil ring, the endoporus of flinger ring has tapering; Flinger ring and connect and leave second space between oil ring, first space communicates with second space, and whole space is labyrinth-like; A large amount of liquid oil that bearing throws away are at first connect oil ring and are caught, and a spot of liquid oil is from the second spatial flow mistake, but flinger ring plays damping function to liquid oil; Also have felt to play the effect of three seals, improved sealing effect greatly, avoided the generation of bearing fan oil leakage phenomenon; Practice thrift cost of production, improved manufacturing efficiency.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of the bearing fan seal arrangement of existing technology;
Accompanying drawing 2 is the structural representation of bearing fan seal arrangement of the present invention;
Wherein: 1, main shaft; 2, bearing support; 3, bearing; 4, bearing cover; 5, gland; 6, felt; 7, first space; 8, flinger ring; 9, connect oil ring; 10, second space; 11, fastening locknut.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of bearing fan seal arrangement shown in accompanying drawing 2; Comprise main shaft 1; Bearing support 2, bearing 3, bearing cover 4 and gland 5 are installed on the said main shaft 1 successively; Said bearing cover 4 is provided with felt 6, and 4 of said bearing 3 and bearing covers are provided with first space 7, is provided with flinger ring 8 in said first space 7 and connects oil ring 9; Said flinger ring 8 is near bearing 3; The said oil ring 9 that connects is near bearing cover 4; The endoporus of said flinger ring 8 has tapering; Said flinger ring 8 and connect 9 of oil rings and leave second space 10; Said first space 7 communicates with second space 10; Whole space is labyrinth-like, and a large amount of liquid oil that bearing throws away are at first connect oil ring 9 and catch, and a spot of liquid oil flows through from second space 10; But 8 pairs of liquid oil of flinger ring play damping function; Also have felt 6 to play the effect of three seals, good sealing effect has been avoided the generation of bearing fan oil leakage phenomenon.
Above-mentioned bearing fan seal arrangement can be provided with fastening locknut 11 in said first space 7; Said fastening locknut 11 is near bearing 3.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
