Abstract

The invention relates to the technical field of rollers, in particular to a roller fixing and sealing device; and the roller fixing and sealing device is simple in structure and excellent in fixing and sealing effect between roller bodies and bearings. The roller fixing and sealing device comprises two side roller bodies and a middle roller body, wherein the two side roller bodies are connected with bearings; the bearings are connected with a bearing base; bearing covers are respectively arranged at the two ends of the bearing covers; external sealing covers and internal sealing covers are respectively arranged between the bearing covers at the two ends of the bearings and the two side roller bodies, and are respectively in fixed connection with the two side roller bodies; the outer sides of the external sealing covers are connected with end covers; the end covers are connected with the bearings at two sides; and sealing rings are arranged between the outer sides of the internal sealing covers and the middle roller body.

Description

A kind of roller fixing seal device

Technical field

The present invention relates to roller technical field, be specially a kind of roller fixing seal device.

Background technique

In cold rolling mill technical field, milling train has the multiple types such as duo mill, three-high mill, four high stand, and roller is divided into back-up roll, intermediate roll and work roll etc., all can arrange fixing seal device between roll body and bearing, general fixing device is fixed insecure, and sealing effect is undesirable.

Summary of the invention

In order to solve the problem, the invention provides a kind of roller seal arrangement, its structure is simple, and between roll body and bearing, fixing seal is effective.

Its technological scheme is such: a kind of roller seal arrangement, it is characterized in that, it comprises both sides roll body and middle roll body, described both sides roll body connection bearing, described bearing coupling shaft bearing, described bearing support two ends arrange bearing cap respectively, between the described bearing cap at described bearing two ends and described both sides roll body, outside seal lid and inner sealing lid are set respectively, described outside seal lid is fixedly connected with described both sides roll body respectively with described inner sealing lid, end cap is connected outside described outside seal lid, described end cap connects two side bearings, outside described inner sealing lid and between described middle roll body, seal ring is set.

It is further characterized in that, arranges draw-in groove inside described outside seal lid, inner sealing lid, arranges the space ring lid coordinated with described bearing cap in described draw-in groove;

Between described bearing cap and described outside seal lid, inner sealing lid, back-up ring is set.

After adopting structure of the present invention, outside seal lid and inner sealing lid are set between the bearing cap at bearing two ends and both sides roll body respectively, outside seal lid is fixedly connected with both sides roll body respectively with inner sealing lid, end cap is connected outside outside seal lid, end cap connects two side bearings, arrange seal ring outside inner sealing lid and between middle roll body, compact overall structure is reasonable, and good fixing seal effect is played in the cooperation of the cooperation of outside seal lid and end cap, inner sealing lid and seal ring.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.
