Abstract
The utility model relates to a sealing device of a fan bearing seat, comprising a main shaft, wherein a bearing seat, a bearing, a bearing seat end cover and a press cover are orderly mounted on the main shaft; the bearing seat end cover is provided with a felt; a first space is arranged between the bearing and the bearing seat end cover; an oil retaining ring and an oil containing ring are arranged in the first space; an internal hole of the oil retaining ring has conical degree; a second space is reserved between the oil retaining ring and the oil containing ring; and the first space is communicated with the second space. According to the sealing device of the fan bearing seat provided by the utility model, entire space is like a maze; a good deal of liquid oil thrown out by the bearing is contained by the oil containing ring at first, a small quantity of liquid oil flows through the second space, but the oil retaining ring has a damping action on the liquid oil, and the field further has a third sealing action so as to greatly increase sealing effect, avoid the phenomenon that the bearing seat leaks oil, save production cost and increase production efficiency.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates 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.
The model utility content
The utility model purpose is the bearing fan seal arrangement that a kind of good sealing effect is provided for the deficiency that overcomes existing technology.
For achieving the above object; The technological scheme that the utility model adopts is: 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; Be provided with first space between said bearing and bearing cover, be provided with flinger ring in said first space and connect 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 utility model compared with prior art has advantage:
The bearing fan seal arrangement of the utility model, 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 the utility model technological scheme 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 the bearing fan seal arrangement of the utility model;
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 and specific embodiment the utility model is done further to specify.
The described a kind of bearing fan seal arrangement of the utility model 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.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
