Abstract
The utility model provides a sealing structure of a sealing type four-row tapered roller bearing. The sealing structure consists of a sealing type four-row tapered roller bearing and a sealing ring. The sealing structure disclosed by the utility model has the beneficial effects that the contact area is increased; the loosening and the displacement of the intermediate sealing ring due to axial movement of two inner rings in the operation process of the bearing are avoided and the falling off due to play within axial axial play is avoided. The sealing structure has the advantages of convenience for use, simple structure and reduced cost.
Description
Technical field
The utility model belongs to the bearing seal field, especially relates to a kind of improvement of operation roll of mill sealed four row tapered roller bearing sealing means.
Background technique
The sealing of bearing will keep inner good lubricating status exactly, and stop cooling water, iron scale, impurity to immerse working surface, thereby reach the purpose in the working life that prolongs bearing, the operation roll of mill bearing all adopts the sealed four row tapered roller bearing, because bearing seal problem, often cause bearing because grease contaminated, loss, make the part time job surface abrasion, peel off even cracked.Existing bearing seal structure is complicated, and parts are more, and the effective dimensions of rubber parts is thinner, and comes off easily, and does not consider that bearing is reused and damage the problem of sealing when detachable.
Summary of the invention
Problem to be solved in the utility model provides a kind of bearing seal structure, especially is fit to the sealing of continuous hot-rolling mill workroll bearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of sealing configuration of sealed four row tapered roller bearing, and by bearing, seal ring forms, and sealing configuration is overall structure form.
Further, two erection opening have been added on the outer side guard plate of sealing.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, strengthened area of contact, avoided bearing in movement process, two inner rings have guaranteed that because moving axially the loosening and displacement that causes the intermediate seal circle play in the axial internal clearance scope is unlikely to come off; Avoid simultaneously dismantling bearing at every turn sealing is caused in various degree damage.Easy to use, simple in structure, cost.

Embodiment
As shown in Figure 1 and Figure 2, a kind of sealing configuration of sealed four row tapered roller bearing, by bearing, seal ring forms, and sealing configuration is overall structure form.
Seal and added two erection opening on the outer side guard plate.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (2)
1. the sealing configuration of a sealed four row tapered roller bearing, by bearing, seal ring forms, and it is characterized in that: sealing configuration is overall structure form.
2. the sealing configuration of sealed four row tapered roller bearing according to claim 1 is characterized in that: seal and added two erection opening on the outer side guard plate.
