Abstract
The utility model discloses a shield is glued in area of three lip rubber of external diameter, including being the annular skeleton of circle, rubber circle, hem, lasso, thin rubber and bearing, the inner off -plate reason of skeleton has inward bellying, the terminal surface inner edge has outside recess in the skeleton, the tight fit is cup jointed and is set up the annular rubber circle of circle in the recess, the radial extension of inner wall of rubber circle is provided with three rings of seal lips, the utility model discloses a with skeleton internal diameter and bearing tight fit, thin rubber under the hem closely laminates with the lasso, prevent that oil of axle bearing from spilling over from the endotheca, lip limit rubber on three rings of seal lips of skeleton external diameter, prevent that outside pollutant from getting into the bearing, prevent again that the inside grease of bearing is excessive, play fine sealed effect, compared with the prior art, machining is simple, the shaping is easy, and it is good to have intensity, the sealed splendid characteristics of effect, the service life of the bearing is in serious pollution thing environment is prolonged.
Description
[technical field]
The utility model relates to the technical field of Bearing fittings, particularly a kind of technical field of band glue dust cover of external diameter three lip rubber.
[background technique]
Dust cover is the critical component that bearing runs well in rugged environment, and it plays protection bearing from erosion and pollution, and bearing can be worked in good clean lubrication environment.And the inside of bearing is due to a large amount of grease lubrication of needs, if sealing effect is bad, can grease be produced excessive, affect the running of bearing.There is following shortcoming in conventional dust cover and seal ring: 1, dust cover assembles rear intensity better on bearing, but sealing effect is not good; 2, on bearing, after assembling, sealing effect is better, but intensity is not good.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of band glue dust cover of external diameter three lip rubber is proposed, the grease of bearing can be made not easily to leak, outside foreign material and dust are difficult to invade inside, greatly improve the working life of bearing, processing is simple, easily shaping, intensity is good, and sealing effect is splendid.
For achieving the above object, the utility model proposes a kind of band glue dust cover of external diameter three lip rubber, comprise in circular skeleton, rubber ring, flanging, lasso, thin rubber and bearing, the interior edge face outer rim of described skeleton has inside lug boss, described skeleton interior edge face inner edge has outside reentrant part, in the female portion, drive fit socket arranges circular rubber ring, and the inwall of described rubber ring is radial extended three circle sealing lips.
As preferably, the female portion is equipped with terraced steps, and rubber ring tightly fits in above-mentioned terraced steps.
As preferably, described three circle sealing lips are in the outside being axially in above-mentioned lug boss.
As preferably, described skeleton internal diameter and bearing drive fit, described flanging is on rubber ring, and the thin rubber under described flanging and lasso fit tightly, and described thin rubber is above lasso.
As preferably, described bearing having axle inner ring and axle outer ring, matches with skeleton in described axle inner ring and axle outer ring.
As preferably, the outer wall of described lug boss is outer little interior large toroidal surface structure.
The beneficial effects of the utility model: the utility model passes through skeleton internal diameter and bearing drive fit, thin rubber under flanging and lasso fit tightly, prevent bearing grease from overflowing from inner sleeve, lip limit rubber on three circle sealing lips of skeleton external diameter, prevent outside pollutant from entering bearing, prevent again Bearing inner grease excessive, play good sealing effect, compared with prior art, processing is simple, easily shaping, and it is good to have intensity, the feature that sealing effect is splendid, improves the working life of bearing in serious pollution substance environment.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is enlarged section of the present utility model;
Fig. 3 is the structural representation that the utility model is applied to bearing.
In figure: 1-skeleton, 2-rubber ring, 3-sealing lip, 4-recessed portion, 5-lug boss, 6-outer wall, 7-flanging, 8-lasso, 9-thin rubber, 10-bearing, 11-axle inner ring, 12-axle outer ring.
[embodiment]
Consult Fig. 1, Fig. 2 and Fig. 3, the utility model comprises in circular skeleton 1, rubber ring 2, flanging 7, lasso 8, thin rubber 9 and bearing 10, the interior edge face outer rim of described skeleton 1 has inside lug boss 5, described skeleton 1 interior edge face inner edge has outside reentrant part 4, in the female portion 4, drive fit socket arranges circular rubber ring 2, the inwall of described rubber ring 2 is radial extended three circle sealing lips 3, the female portion 4 is equipped with terraced steps, rubber ring 2 tightly fits in above-mentioned terraced steps, described three circle sealing lips 3 are in the outside being axially in above-mentioned lug boss 5, described skeleton 1 internal diameter and bearing 10 drive fit, described flanging 7 is on rubber ring, thin rubber 9 under described flanging 7 fits tightly with lasso (8), described thin rubber 9 is above lasso 8, described bearing 10 there are axle inner ring 11 and axle outer ring 12, match with skeleton 1 in described axle inner ring 11 and axle outer ring 12, the outer wall 6 of described lug boss 5 is in outer little interior large toroidal surface structure.
Utility model works process:
The band glue dust cover of a kind of external diameter three of the utility model lip rubber in the course of the work, skeleton 1 internal diameter and bearing 10 drive fit, thin rubber 9 under flanging 7 fits tightly with lasso 8, thin rubber 9 is above lasso 8, prevent bearing grease from overflowing from inner sleeve, reentrant part 4 is equipped with terraced steps, the outer wall of rubber ring 2 and the sidewall interference fit of terraced steps, rubber ring 2 is made to combine closely in skeleton 1, three circle sealing lips 3 on rubber ring 2 overlap upper lip rubber, prevent outside pollutant from entering bearing 10, prevent again bearing 10 internal grease excessive, compared with prior art, processing is simple, easily shaping, and it is good to have intensity, the feature that sealing effect is splendid, improve the working life of bearing in serious pollution substance environment.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
