CN106369164A - Sealing structure of deoiling roller - Google Patents

Abstract

The invention relates to a sealing structure of a deoiling roller. The sealing structure is characterized in that a bearing outer sleeve arranged on two sides of a deoiling roller is limited by a clamp spring; an inner sleeve is limited by a shaft sleeve; gaps are formed between a gland of a bearing and the shaft sleeve as well as between the shaft sleeve and a shaft; two parallel O-shaped sealing rings coaxially sleeve the shaft, and are positioned in the gap between the shaft sleeve and the shaft; a groove is formed in the corresponding gland position above the shaft sleeve; and a shaft seal being coaxial with the shaft sleeve is embedded in the groove. The sealing structure provided by the invention has the advantages that two aspects of the sealing effect are added by adopting two measures, thereby solving the problem that the sealing effect is absent in the past; and the bearing operation environment can be effectively separated from the external environment, thereby reducing damage to the bearing and cutting down the expenditure.

Description

Except oiling roller sealing structure

Technical field

The invention belongs to oiling roller sealing structure is removed in cold-rolling equipment field, especially one kind.

Background technology

In original cold-rolling mill produces, except oiling roller both sides bearing outside is spacing by jump ring, inner sleeve is spacing by axle sleeve, pressure There is clear gap between lid and shaft room, axle sleeve and axle, lead to the liquid such as rolling emulsion, water to enter bearing operation environment, long Phase soaks bearing, and bearing easily damages.Need to often change, labor intensive material resources, cause to waste.

Content of the invention

It is an object of the invention in place of overcoming the deficiencies in the prior art, provide one kind can effectively by bearing operation environment with External environment separate except oiling roller sealing structure.

The present invention solves its technical problem and takes technical scheme below to realize:

One kind removes oiling roller sealing structure, and except oiling roller both sides bearing outside is spacing by jump ring, inner sleeve is spacing by axle sleeve, in axle Between the gland holding and axle sleeve, between axle sleeve and axle, there is gap, parallel " o " type sealing ring of coaxial package two on axle, This two sealing rings are located on the space between axle sleeve and axle, arrange groove, recessed on above axle sleeve corresponding gland position Setting-in one axle envelope coaxial with axle sleeve in groove.

And, on described gland position, the groove of setting is to be fixedly mounted with above axle sleeve corresponding gland position or make one The annular pressing plate coaxial with axle sleeve, this pressing plate forms groove with the lateral wall of gland.

And, the described assembling sealing patent laminated structure except oiling roller is to be processed axle sleeve and gland, inside axle sleeve Increase twice " o " type ring recess and be set with " o " type sealing ring, the outside of gland increases an axle envelope mounting groove, the steps include:

First bearing is installed in place, then by upper for gland pressure it is ensured that gland contacts compression with bearing outer ring, is fixed by jump ring Gland；

Axle sleeve with " o " type sealing ring is installed in place it is ensured that compressing bearing inner sleeve；

Finally axle envelope is installed in the gland water jacket processing it is ensured that axle envelope is installed in place can't come off.

Advantages of the present invention and good effect are:

Original axle sleeve is processed by the present invention, increases by two o type circles as sealing, can effectively prevent in bearing Outflow of lubrication oil, can prevent the water in external environment condition or other high-temp liquids from flowing into simultaneously, cause bearing damage；In addition, Gland is re-worked, rear increase a water jacket that can fill axle envelope, increase axle envelope after, except oiling roller high-speed rotation when Wait, preferable rotatory sealing effect can be reached, can grease-proof and waterproof；Two measures seal of both increased, and solve Go do not have Packed problem, can effectively bearing operation environment and external environment be separated, reduce bearing damage, reduce expenses.

Brief description

Fig. 1 is to remove oiling roller side bearing assembling structure schematic diagram (axis section view) in prior art；

Fig. 2 is to remove oiling roller side bearing assembling structure schematic diagram (axis section view) in the present invention.

Specific embodiment

The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following examples are descriptive , it is not determinate it is impossible to protection scope of the present invention is limited with this.

A kind of remove oiling roller sealing structure, pass through that jump ring 1 is spacing for except oiling roller both sides bearing outside 5, inner sleeve is limited by axle sleeve 3 Position, has clear gap 7, after external high temperature liquid enters, direct shadow between the gland 2 and axle sleeve of bearing, between axle sleeve and axle Ring this situation of service life of internal bearings, parallel " o " type sealing ring 6 of coaxial package two on axle, this two sealings Circle is located on the space between axle sleeve and axle, arranges groove on above axle sleeve corresponding gland position, is embedded in one in groove The axle envelope 8 coaxial with axle sleeve.

On gland position, the groove of setting is to be fixedly mounted with or make one on above axle sleeve corresponding gland position with axle sleeve together The annular pressing plate 4 of axle, this pressing plate forms groove with the lateral wall of gland.

The assembly process of said structure is:

Axle sleeve and gland are processed, twice " o " type ring recess will be increased inside axle sleeve and be set with " o " type sealing ring, pressure The outside of lid increases an axle envelope mounting groove, the steps include:

First bearing is installed in place, then by upper for gland pressure it is ensured that gland contacts compression with bearing outer ring, is fixed by jump ring Gland；

Axle sleeve with " o " type sealing ring is installed in place it is ensured that compressing bearing inner sleeve；

Finally axle envelope is installed in the gland water jacket processing it is ensured that axle envelope is installed in place can't come off.

Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage Solution: without departing from the present invention and spirit and scope of the appended claims, various replacements, to change and modifications be all possible, Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.

Claims (3)

1. one kind removes oiling roller sealing structure, and except oiling roller both sides bearing outside is spacing by jump ring, inner sleeve is spacing by axle sleeve, in bearing Gland and axle sleeve between, there is gap between axle sleeve and axle it is characterised in that: coaxial package two parallel " o " on axle Type sealing ring, this two sealing rings are located on the space between axle sleeve and axle, arrange on above axle sleeve corresponding gland position Groove, is embedded in an axle envelope coaxial with axle sleeve in groove.
