Abstract

The invention discloses a bearing sealing waterproof structure, which comprises a roller drum. The roller drum is connected with a roller head through interference fit; the end part of the roller drum is an oblique plane in a horn mouth shape; the roller head is mounted on a bearing block through a bearing; a waterproof shaft sleeve and an end cover are respectively mounted on the left side and the right side of the bearing block; O-shaped sealing rings are mounted at stopping opening roots of the waterproof shaft sleeve and the end cover; and a first liquid collection tank, a labyrinth sealing tank, a second liquid collection tank, a water seal and a skeleton oil seal are sequentially arranged between the roller head and the waterproof shaft sleeve from left to right. The amount of water entering a roller is reduced as much as possible by a non-touch seal; a contact sealing ring plays a last waterproof role; by using the bearing sealing waterproof structure, the amount of the water reaching to the water seal is effectively reduced, so the service life of the sealing ring is prolonged, and the whole sealing waterproof effect is guaranteed.

Description

A kind of bearing seal waterproof construction
Technical field
The present invention relates to a kind of bearing seal waterproof construction.
Background technique
In metallurgical equipment, there are many rollers that are operated in the environment such as a large amount of cooling liquids, Lubricants and high pressure dephosphorization water, application at present has the seal ring of use and labyrinth sealing groove etc. more widely, but under the above-mentioned rugged environment of roller long-term work, a large amount of greasy filth is deposited in seal ring place, accelerate the aging, damaged of seal ring, water-tight lost efficacy, and water enters affects the lubricating to bearing damage of bearing after bearing.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of bearing seal waterproof construction, effectively reduce the water yield that arrives water seal place, thereby improved the seal ring life-span, ensure integral sealing waterproofing effect.
In order to achieve the above object, the technological scheme that the present invention takes is:
A kind of bearing seal waterproof construction, comprise roller 1, roller 1 is connected by interference fit with roller head 2, roller 1 end is the inclined-plane 10 of a horn mouth shape, roller head 2 is arranged on bearing support 8 by bearing 7, bearing support 8 left sides are provided with waterproof axle sleeve 4, bearing support 8 right sides are provided with end cap 9, waterproof axle sleeve 4 and end cap 9 seam roots are equipped with O RunddichtringO 5, are provided with successively from left to right collecting tank 11, labyrinth sealing groove 12, No. two collecting tanks 13, water seal 3 and outside framework oil seals 6 between roller head 2 and waterproof axle sleeve 4.
A described collecting tank 11 is positioned at 10 belows, inclined-plane of horn mouth shape, and No. two described collecting tanks 13 are located at labyrinth sealing groove 12 lower rights.
Described water seal 3 adopts abrasive rubber material.
Beneficial effect of the present invention is: reduce by noncontact seal the water yield that enters roller, contact sealing ring plays last one waterproof action as far as possible.Noncontact seal has utilized the centrifugal force of roller rotation generation and the gravity of water, and the path of labyrinth seal complexity and the inner air retaining thereof make the water in external environment be difficult to arrive seal ring position.Contact sealing ring is the water seal of pure glue end face and outside framework oil seal, can prevent that dust, powder, water and their mixtures from entering bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is Fig. 1 partial enlarged view.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
See figures.1.and.2, a kind of bearing seal waterproof construction, comprise roller 1, roller 1 is connected by interference fit with roller head 2, roller 1 end is the inclined-plane 10 of a horn mouth shape, roller head 2 is arranged on bearing support 8 by bearing 7, bearing support 8 left sides are provided with waterproof axle sleeve 4, bearing support 8 right sides are provided with end cap 9, waterproof axle sleeve 4 and end cap 9 seam roots are equipped with O RunddichtringO 5, are provided with successively from left to right collecting tank 11, labyrinth sealing groove 12, No. two collecting tanks 13, water seal 3 and outside framework oil seals 6 between roller head 2 and waterproof axle sleeve 4.
A described collecting tank 11 is positioned at 10 belows, inclined-plane of horn mouth shape, and No. two described collecting tanks 13 are located at labyrinth sealing groove 12 lower rights.
Described water seal 3 adopts abrasive rubber material.
Working principle of the present invention is:
Roller 1 end is the inclined-plane of a horn mouth shape, and in the time that roller 1 rotates, the water that enters chamfered region is subject to centrifugal action under the drive of roller 1, is thrown to roller 1 outside.
When in the situation that roller 1 rotating speed is lower or the external environment condition water yield is larger, if some water enters after spindle nose, this part water is pooled in a collecting tank 11 under the effect of gravity, and the water yield is no more than in protruding 4 the height situations in collecting tank 11 the right, and water flows down along a collecting tank 11.
Collecting tank 11 the right are a labyrinth sealing groove 12, and in roller head 2 High Rotation Speed situations, water is difficult to by labyrinth sealing groove 12.
Labyrinth sealing groove 12 lower rights are designed with collecting tank 13 No. two, and function is identical with a collecting tank 11.
Structure all adopts contactless friction sealed structure above, and reliable performance greatly reduces the possibility that arrives water seal 3 places by above-mentioned path.
Water seal 3 adopts abrasive rubber material, can prevent that dust, powder, water and their mixture and grease from entering into bearing.
Outside framework oil seal 6 can prevent that lubricant oil in bearing is to external leakage.
In addition, be designed with O RunddichtringO 6 at waterproof axle sleeve 4 and end cap 9 with bearing support 8 junction planes, anti-sealing is invaded bearing support from this position.
