Abstract
The invention provides a sealed bearing seat. To the bearing seat in a bad working environment, impurities easily enter the bearing seat to cause corrosion and influence transmission, and therefore the smooth running of production is directly influenced. The sealed bearing seat comprises a bearing shell (1), wherein one end of the bearing shell is connected with a blank cap (2), and the other end of the bearing shell is connected with a sealing gland (4) through a labyrinth seal (3). Sealing gaskets (5) are respectively arranged between the bearing shell and the blank cap and the bearing shell and the sealing gland, and a shaft sleeve (6) is installed in the bearing shell. A shaft head (7) is installed in the bearing sleeve, a flange (8) is installed outside the shaft head, and the outer surface of the flange is connected with a flange gland (9). The bearing seat has the advantages of reliability in sealing, simple process, small abrasion and long service life.
Description
Technical field
The present invention relates to a kind of sealed bearing, belong to mechanical Component manufacturing technology field.
Background technique
Bearing support is mounted in and on steam turbine body or basis, is used for the member of spring bearing, bearing support is the cleaning to bearing support mold joint in use, very bothersome, also be easy to ignore, operator applies kerosene and thoroughly bearing support mold joint is cleaned one time, not only can prevent that bearing support from can not crush injury, and through cleaning, can, being got through by the air vent of the residue of releasing agent or the obstruction of other dirt on bearing support, be conducive to the discharge of the medium-sized intracavity gas of injection process.Bearing support also should enter comprehensive cleaning inspection before installing.Bearing support inner chamber is scraped off foul with scraper, with cloth, dip in gasoline or solvent is cleaned foul, watched flawless and sand holes, to prevent from being in operation, occur oil impregnate.Bearing cap and bearing support mating face, bearing support should grind to scrape with bearing oil deflector junction plane and coordinate, and checks that with clearance gauge ，Qi gap must not be greater than 0.03 millimeter.Place the backplate surface of bearing support and also will clean out, do not have damage, corrosion and burr.
For the bearing support being in severe working environment, impurity very easily immerses, and causes corrosion, affects transmission, thereby directly impact production carries out smoothly.
Summary of the invention
The object of the invention is provides a kind of sealed bearing for the problem of above-mentioned existence, can effectively avoid impurity to invade the obstruction causing, thereby improve the working life of step for the bearing support being in for a long time in severe working environment, increases its repair cycle.
Above-mentioned object is achieved through the following technical solutions:
Sealed bearing, comprise bearing case, described bearing case one end connects stifle, the other end connects sealing gland by labyrinth sealing, between described bearing case and described stifle and described sealing gland, have respectively sealing gasket, axle sleeve is installed in described bearing case the inside, and spindle nose is installed in described axle sleeve the inside, described spindle nose outside mounting flange, described flange outside adpting flange gland.
Described sealed bearing, has stuffing box packing between described spindle nose and described axle sleeve.
Described sealed bearing, has sealing layer between described axle sleeve and described bearing case.
Beneficial effect:
1. in sleeve end of the present invention and sealing gland formation labyrinth sealing ，Qi gap, be full of the synthetic complex aluminium base grease with good water resistance and better mechanical stability, form first sealing.In the formed space of labyrinth seal groove and axle sleeve and bearing case, be full of the synthetic complex aluminium base grease with good water resistance and better mechanical stability.Fully guarantee sealing effect.The present invention seals reliably, and technique is simple, and wearing and tearing are few, long service life.
2. further, the present invention forms second by sealing layer again and seals between axle sleeve and bearing case, because axle sleeve material is filled polytetrafluoroethylene, in teflon, adds sealing layer, makes its friction factor reduce wear resistance simultaneously and is improved.Therefore between axle sleeve and sealing material, wear and tear less, the life-span extends greatly.After two seals, sealing effect is very reliable.Bearing case two ends are connected with sealing gland with stifle respectively, add respectively sealing gasket to seal therebetween, and owing to being static seal, sealing is reliable.
Accompanying drawing explanation
Fig. 1, structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Embodiment 1:
As shown in Figure 1, sealed bearing of the present invention, comprise bearing case 1, described bearing case one end connects stifle 2, and the other end is by labyrinth sealing 3 connection sealing glands 4, between described bearing case and described stifle and described sealing gland, has respectively sealing gasket 5, axle sleeve 6 is installed in described bearing case the inside, spindle nose 7 is installed in described axle sleeve the inside, described spindle nose outside mounting flange 8, described flange outside adpting flange gland 9.
Embodiment 2:
Described sealed bearing, has stuffing box packing 10 between described spindle nose and described axle sleeve.
Embodiment 3:
Described sealed bearing, has sealing layer 11 between described axle sleeve and described bearing case.
Claims (3)
1. a sealed bearing, comprise bearing case, it is characterized in that: described bearing case one end connects stifle, the other end connects sealing gland by labyrinth sealing, between described bearing case and described stifle and described sealing gland, have respectively sealing gasket, axle sleeve is installed in described bearing case the inside, and spindle nose is installed in described axle sleeve the inside, described spindle nose outside mounting flange, described flange outside adpting flange gland.
2. sealed bearing according to claim 1, is characterized in that: between described spindle nose and described axle sleeve, have stuffing box packing.
