Abstract

The utility model relates to a supporting roller, in particular to a seepage-proof supporting roller. The supporting roller comprises a roller body, a roller core and roll shafts. The roller core is arranged in the roller body, the roll shafts are arranged at the two ends of the roller core, a seepage-proof shell is fixedly connected to the roller body and are cylindrical, the roll shafts penetrate through the seepage-proof shell, a fixing plate is welded to each open end of the seepage-proof shell and is fixedly connected with the roller body through bolts, embedding grooves are formed in the roll shafts, the edges of open holes of the seepage-proof shell are arranged in the embedding grooves, and the seepage-proof shell is a ceramic body. According to the supporting roller, sealing performance of the roller body and the roll shafts can be enhanced, the service life of the seepage-proof supporting roller can not be shortened due to seepage of external objects, cost is saved, and efficacy is improved.

Description

Antiseepage type backing roll

Technical field

The utility model relates to a kind of backing roll, especially antiseepage type backing roll.

Background technology

Backing roll is help roll conventional on a kind of milling train, backing roll plays very important effect in Rolling Production, therefore improve backing roll quality, extend its life-span key and be the structural strength of backing roll, because sealing between the two ends roll shaft of existing backing roll and roll body is poor, easily by sewage or dust, infiltrated, cause shorten its service life.

Utility model content

In order to overcome the poor deficiency of existing backing roll sealing, the utility model provides antiseepage type backing roll.

The utility model solves the technical scheme that its technical problem adopts: antiseepage type backing roll, comprise roll body, roller core and roll shaft, and roller core is placed in roll body, roller core two ends are provided with roll shaft, on roll body, be fixedly connected with antiseepage shell, antiseepage shell is cylindrical shape, and roll shaft is through antiseepage shell.

According to another embodiment of the present utility model, further comprise that antiseepage shell opener end has been welded to connect fixed head, fixed head is fixedly connected with roll body by bolt, and roll shaft is provided with embedded groove, and the tapping edge of antiseepage shell is placed in embedded groove.

According to another embodiment of the present utility model, further comprise that antiseepage shell is ceramic body.

The beneficial effects of the utility model are that this backing roll can be strengthened the sealing of roll body and roll shaft, makes it can not save cost because foreign object infiltrates reduction of service life, has improved effect.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the structural representation of antiseepage type backing roll;

1. roll bodies in figure, 2. roller core, 3. roll shaft, 4. antiseepage shell, 5. fixed head, 6. bolt, 7. embedded groove.

The specific embodiment

If Fig. 1 is the structural representation of antiseepage type backing roll, antiseepage type backing roll, comprises roll body 1, roller core 2 and roll shaft 3, roller core 2 is placed in roll body 1, roller core 2 two ends are provided with roll shaft 3, are fixedly connected with antiseepage shell 4 on roll body 1, and antiseepage shell 4 is cylindrical shape, roll shaft 3 is through antiseepage shell 4, antiseepage shell 4 openends have been welded to connect fixed head 5, and fixed head 5 is fixedly connected with roll body 1 by bolt 6, and roll shaft 3 is provided with embedded groove 7, the tapping edge of antiseepage shell 4 is placed in embedded groove 7, and antiseepage shell 4 is ceramic body.

First roll shaft 3 is passed to antiseepage shell 4, then the fixed head 5 on antiseepage shell 4 openends is fixedly connected with to the side of upper roll body 1 by bolt 6, after fixing, on the perforation edge of antiseepage shell 4 is just in time placed in embedded groove, so just can structurally shut sewage dust completely and extend into the possibility in gap, this backing roll can be strengthened the sealing of roll body and roll shaft, makes it can not infiltrate reduction of service life because of foreign object, save cost, improved effect.
