Abstract
The utility model discloses a shield is glued in area of three lip rubber of internal diameter, including being the annular skeleton of circle, rubber circle, thin rubber, lasso, hem 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 hem is on the external diameter of skeleton, 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 from spilling over from the overcoat, three lip limits of skeleton internal diameter, the outside seal lip that is close to the skeleton is used for preventing external pollutant to get into the bearing, ensures that the bearing is intact, the grease was excessive in inboard seal lip was used for preventing the bearing, compare with prior art, processing simply, the shaping is easy to 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 of band glue dust cover of 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 of internal 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 internal diameter three lip rubber, comprise in circular skeleton, rubber ring, thin rubber, lasso, flanging 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, and described flanging is on the external diameter of skeleton.
As preferably, described 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, the flanging of described skeleton external diameter and bearing drive fit, the thin rubber under flanging and lasso fit tightly, and described thin rubber is in the below of lasso.
As preferably, the arranged outside of described sealing lip inner edge breach.
As preferably, the outer wall of described lug boss is outer little interior large toroidal surface structure.
As preferably, described bearing having axle inner ring and axle outer ring, matches with skeleton in described axle inner ring and axle outer ring.
The beneficial effects of the utility model: the utility model passes through the flanging of skeleton external diameter and bearing drive fit, thin rubber under flanging and lasso fit tightly, and prevent bearing grease from overflowing from overcoat, three lip limits of skeleton internal diameter, outboard seal lip near skeleton enters bearing for stoping environmental contaminants, guarantee that bearing is intact, the sealing lip of inner side is used for preventing grease in bearing excessive, 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.
