Abstract

The utility model is related to a kind of except oiling roller sealing structure, except oiling roller both sides bearing outside is spacing by jump ring, inner sleeve is spacing by axle sleeve, there is gap between the gland and axle sleeve of bearing, between axle sleeve and axle, parallel " O " type sealing ring of coaxial package two on axle, two sealing rings are located on the space between axle sleeve and axle, and groove is set on the corresponding gland position of above axle sleeve, and an axle envelope coaxial with axle sleeve is embedded in groove.Two measures of the utility model are sealed of both adding, and solve over the problem of not sealing, and effectively can be separated bearing operation environment and external environment, reduction bearing damage, are reduced expenses.

Description

One kind removes oiling roller sealing structure

Technical field

The utility model belongs to cold-rolling equipment field, especially a kind of to remove oiling roller sealing structure.

Background technology

In original cold-rolling mill production, 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, cause the liquid such as rolling emulsion, water to enter bearing operation environment, it is long Phase soaks bearing, and bearing is easily damaged.It need to often change, labor intensive material resources, cause to waste.

Utility model content

The purpose of this utility model is that overcome can be effectively by bearing operation ring there is provided one kind in place of the deficiencies in the prior art What border and external environment were separated removes oiling roller sealing structure.

The utility model solves its technical problem and takes following technical scheme 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 There is gap between the gland and axle sleeve that hold, between axle sleeve and axle, parallel " O " type sealing ring of coaxial package two on axle, Two sealing rings are located on the space between axle sleeve and axle, groove are set on the corresponding gland position of above axle sleeve, recessed One axle envelope coaxial with axle sleeve of setting-in in groove.

Moreover, the groove set on the gland position is to be fixedly mounted with or make one on the corresponding gland position of above axle sleeve The lateral wall formation groove of the coaxial annular pressing plate with axle sleeve, the pressing plate and gland.

Advantage of the present utility model and good effect are：

Original axle sleeve is processed by the utility model, and two O-rings of increase can effectively prevent bearing as sealing Interior outflow of lubrication oil, while can prevent that water or other high-temp liquids in external environment condition from flowing into, causes bearing damage；Separately Outside, gland is re-worked, rear increase by one can be filled after the water jacket of axle envelope, increase axle envelope, what is rotated at a high speed except oiling roller When, preferable rotatory sealing effect can be reached, can grease-proof and waterproof；Two measures are sealed of both adding, and are solved The problem of past does not seal, effectively can separate bearing operation environment and external environment, reduce bearing damage, reduce expenses.

Brief description of the drawings

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

Fig. 2 be the utility model in remove oiling roller side bearing assembling structure schematic diagram (axis section view).

Embodiment

Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment, following examples are to retouch The property stated, be not limited, it is impossible to limit protection domain of the present utility model with this.

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

The groove set on gland position is that to be fixedly mounted with or make one on the corresponding gland position of above axle sleeve same with axle sleeve The lateral wall formation groove of the annular pressing plate 4 of axle, the pressing plate and gland.

The assembly process of said structure is：

Axle sleeve and gland are processed, twice "O"-ring groove will be increased inside axle sleeve and be set with " O " type sealing ring, pressed The outside of lid increases an axle envelope mounting groove, and its step is：

First bearing is installed in place, then by 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 compress bearing inner sleeve；

Finally axle envelope is installed in the gland water jacket processed, it is ensured that axle envelope, which is installed in place, to come off.

Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, those skilled in the art can be with Understand：Do not departing from the utility model and spirit and scope of the appended claims, it is various replace, change and modifications all be can Can, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.

Claims

1. one kind removes oiling roller sealing structure, 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, between axle sleeve and axle there is gap, it is characterised in that：Coaxial package two parallel " O " on axle Type sealing ring, two sealing rings are located on the space between axle sleeve and axle, are set on the corresponding gland position of above axle sleeve Groove, is embedded in an axle envelope coaxial with axle sleeve in groove.

2. according to claim 1 remove oiling roller sealing structure, it is characterised in that：The groove set on the gland position is The outside of an annular pressing plate coaxial with axle sleeve, the pressing plate and gland is fixedly mounted with or made on the corresponding gland position of above axle sleeve Wall formation groove.
