Abstract
The utility model discloses a there is area of three lip rubber of lateral lip limit internal diameter to glue shield, including being the annular skeleton of circle, rubber circle and seal lip, its characterized in that the inner off -plate of skeleton reason has an inward bellying, and interior terminal surface inner edge has an outside recess, 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, there is a side direction rubber lip limit on the skeleton internal diameter, the utility model discloses a with the hem of skeleton external diameter and bearing tight fit, the hem thin rubber down closely laminate with the lasso, prevents that oil of axle bearing follow overcoat from spilling over, three lip limits of skeleton internal diameter, seal lip are used for preventing external pollutant to get into the bearing, ensure that the bearing is intact, prevent simultaneously that the interior grease of bearing is excessive, a side direction rubber lip limit of skeleton internal diameter department cooperates with the retaining ring, and greatly increased seals the effect, compared with the prior art, processing is simple, and the shaping is easy, and it is good to have intensity, the sealed splendid characteristics of effect.
Description
[technical field]
The utility model relates to the technical field of Bearing fittings, particularly a kind of technical field having the band glue dust cover of lateral lip limit internal 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 having lateral lip limit internal diameter three lip rubber is proposed, the grease in bearing can be made not easily excessive, outside serious pollution thing and dust are difficult to invade inside, substantially increase the working life of bearing in serious pollution substance environment, 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 having lateral lip limit internal diameter three lip rubber, comprise in circular skeleton, rubber ring and sealing lip, it is characterized in that the interior edge face outer rim of described skeleton has inside lug boss, 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, described skeleton internal diameter has a side direction rubber lip limit.
As preferably, the female portion is equipped with terraced steps, and rubber ring tightly fits in above-mentioned terraced steps.
As preferably, state flanging and the bearing drive fit of skeleton external diameter, the thin rubber under the flanging on described skeleton external diameter and lasso fit tightly, and a side direction rubber lip limit of described skeleton inner radius coordinates with back-up ring, greatly increases sealing effect.
As preferably, described three circle sealing lips are in the outside being axially in above-mentioned lug boss.
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 the flanging of skeleton external diameter and bearing drive fit, and the thin rubber under flanging and lasso fit tightly, and prevent bearing grease from overflowing from overcoat; Three lip limits of skeleton internal diameter, sealing lip enters bearing for stoping environmental contaminants, guarantees that bearing is intact, prevents grease in bearing excessive simultaneously; A side direction rubber lip limit of skeleton inner radius coordinates with back-up ring, greatly increases 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.
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 plan view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is enlarged section of the present utility model.
In figure: 1-skeleton, 2-rubber ring, 3-sealing lip, 4-side direction rubber lip limit, 5-reentrant part, 6-protrude into portion, 7-outer wall.
[embodiment]
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of band glue dust cover having lateral lip limit internal diameter three lip rubber of the utility model, comprise in circular skeleton 1, rubber ring 2 and sealing lip 3, it is characterized in that the interior edge face outer rim of described skeleton 1 has inside lug boss 6, interior edge face inner edge has outside reentrant part 5, in the female portion 5, drive fit socket arranges circular rubber ring 2, the inwall of described rubber ring 2 is radial extended three circle sealing lips 3, described skeleton 1 internal diameter there is a side direction rubber lip limit 4, the female portion 5 is equipped with terraced steps, rubber ring 2 tightly fits in above-mentioned terraced steps, the flanging of described skeleton 1 external diameter and bearing drive fit, thin rubber under flanging on described skeleton 1 external diameter and lasso fit tightly, a side direction rubber lip limit 4 of described skeleton 1 inner radius coordinates with back-up ring, greatly increase sealing effect, described three circle sealing lips 3 are in the outside being axially in above-mentioned lug boss 6, the outer wall 7 of described lug boss 6 is in outer little interior large toroidal surface structure.
Utility model works process:
The utility model is a kind of has the band glue dust cover of lateral lip limit internal diameter three lip rubber in the course of the work, the flanging of skeleton 1 external diameter and bearing drive fit, thin rubber under flanging on skeleton 1 and lasso fit tightly, prevent bearing grease from overflowing from overcoat, reentrant part 5 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 lip limits of skeleton 1 internal diameter, three circle sealing lips 3 enter bearing for stoping environmental contaminants, guarantee that bearing is intact, prevent grease in bearing excessive simultaneously, a side direction rubber lip limit 4 of skeleton 1 inner radius coordinates with back-up ring, greatly increase 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.
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.
