Abstract
The utility model discloses a fan bearing-seat sealing device which comprises a left flange (11) and a right flange (12), wherein the left flange (11) and the right flange (12) which can be disassembled are connected with a bearing seat (10) and are respectively used for positioning a left and a right bearings; a left screw sleeve (21) is fixedly arranged on the shaft neck of a transmission shaft outside the left bearing; a right screw sleeve (22) is fixedly arranged on the shaft neck of a transmission shaft outside the right bearing; the left screw sleeve (21) and the right screw sleeve (22) are provided with left screw teeth (23) and right screw teeth (24), and the screw directions of the left screw teeth (23) and the right screw teeth (24) are opposite. An air outlet hole (30) communicated with an oil storing cavity (13) is arranged on the bearing seat (10). The utility model has the advantages that an effective and reliable seal can be realized between the bearing seat and the transmission shafts, the utility model has good sealing performance and effectively suppresses the raising of the temperature of the oil storing cavity in the bearings and the bearing seat. Thus, the service live of the bearing is prolonged and the failure of lubrication oil is avoided.
Description
Technical field
The utility model relates to a kind of seal arrangement, especially the seal arrangement of bearing fan.
Background technique
At each field extensive use centrifugal blower and induced draught fans such as forging, smelting, heat treatment, boiler, deduster and mass transport, because of its application is wide, so domestic have quite a lot of blower fan to make the special manufacturer.At present, the sticking formula of tradition hair is adopted in the sealing of bearing fan more, mainly has the defective of following several aspects, and sealing effect is poor, and leakage of oil is comparatively serious, and during the blower fan start, not noting slightly will oil starvation, needs often to refuel, otherwise easily causes bearing burnt and stop production; The high temperature that produces during because of fan operation, caused inner with the extraneous temperature difference and the pressure of bearing support that bigger difference is all arranged, the inner fluid of bearing support is along with the bearing support temperature raises, oily failure phenomenon easily takes place, inner higher pressure is extruded bearing support with fluid, also can cause the bearing support oil starvation and damages; Continual oil leaking pollution production environment, leakage of oil infilters concrete pedestal, if things go on like this can cause whole concrete pedestal to scrap because of bull pine.Because the problems referred to above that the bearing fan sealing exists can't solve, enterprise is the normal operation of assurance equipment, often has only the equipment configuration number cover impeller of blower measure of operation in turn of adopting.
The model utility content
Technical problem to be solved in the utility model provides a kind of bearing fan seal arrangement that good seal performance is arranged.
The technological scheme that its technical problem that solves the utility model adopts is: bearing fan seal arrangement of the present utility model, comprise the left flange plate, the right flange plate that removably connect with bearing support and be respectively applied for left and right bearing location, it is characterized in that: be set with the left hand screw cover on the transmission shaft axle journal outside the described left bearing, be set with the right-hand screw cover on the transmission shaft axle journal outside the described right bearing; Described left hand screw cover, right-hand screw cover have the opposite left hand screw tooth of Hand of spiral, right-hand screw tooth.
After taking abovementioned technology, during fan operation, left hand screw cover, right-hand screw cover rotate with transmission shaft, the left hand screw tooth that Hand of spiral is opposite on it, right-hand screw tooth produce the air-flow in the bearing support oil storage chamber, stop lubricant oil to leak outside, between bearing support and transmission shaft, realize sealing effectively reliably.
As improvement of the technical scheme, for suppressing the rising of bearing, store oil cavity temperature, on bearing support, offer the air outlet hole that communicates with oil storage chamber, the air-flow that left hand screw cover, right-hand screw cover produce is entering oil storage chamber after this air outlet hole is discharged, and the heat that the bearing high speed rotating is produced is taken out of simultaneously.
The beneficial effects of the utility model are, can between bearing support and transmission shaft, realize sealing effectively reliably, have good seal performance, and can also suppress the rising of oil storage chamber temperature in bearing, the bearing support effectively, thereby improve the working life of bearing and avoid lubricant oil oil to lose efficacy.
Description of drawings
This specification comprises following three width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model bearing fan seal arrangement;
Fig. 2 is the plan view of left hand screw cover in the utility model bearing fan seal arrangement;
Fig. 3 is the plan view of right-hand screw cover in the utility model bearing fan seal arrangement;
Component, position and numbering among the figure: bearing support 10, left end flange plate 11, right-hand member flange plate 12, oil storage chamber 13, left hand screw cover 21, right-hand screw cover 22, left hand screw tooth 23, right-hand screw tooth 24, air outlet hole 30, oil cleaner screen 31.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, bearing fan seal arrangement of the present utility model comprises that removably connect and be respectively applied for left flange plate 11, the right flange plate 12 of left and right bearing location with bearing support 10.Be set with left hand screw cover 21 on the transmission shaft axle journal outside the left bearing, be set with right-hand screw cover 22 on the transmission shaft axle journal outside the right bearing.As Fig. 2, shown in Figure 3, left hand screw cover 21, right-hand screw cover 22 have the opposite left hand screw tooth 23 of Hand of spiral, right-hand screw tooth 24.During fan operation, left hand screw cover 21, right-hand screw cover 22 rotate with transmission shaft, the left hand screw tooth 23 that Hand of spiral is opposite on it, right-hand screw tooth 23 produces in oil storage chamber 13 air-flow, stops lubricant oil to leak outside, and realizes sealing effectively reliably between bearing support 10 and transmission shaft.
As shown in Figure 1, also can on bearing support 10, offer the air outlet hole 30 that communicates with oil storage chamber.The air-flow that enters oil storage chamber interior 13 is discharged oil storage chambers 13 through air outlet hole 30, and the heat that the bearing high speed rotating is produced is taken out of simultaneously, suppresses the rising of temperature in bearing and the oil storage chamber 13.For avoiding air-flow to take mist of oil out of, the oil cleaner screen 31 that covers air outlet hole 30 ports can be set in oil storage chamber 13.
It is to be noted, above the described principles more of the present utility model that just explain through diagrams, because the those of ordinary skill to constructed field is easy to carry out on this basis some modifications and change, therefore this specification be not be the utility model to be confined to shown in and in described concrete structure and the Applicable scope, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
