Abstract
The utility model relates to a kind of metallurgical roller with many sealings, comprise body, first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip, and be sheathed on the steel band of body periphery, first sealing lip outside is provided with open type annular spring groove, be arranged with an annular spring in the annular spring groove, body is formed by 85 ° of A nitrile butadiene rubber sulfurations, first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip is formed by 75 ° of A nitrile butadiene rubber sulfurations, body and described first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip is fixed together, and is provided with the elasticity bin cure layer of silica gel of bonding annular spring and annular spring groove inwall between annular spring and the annular spring groove inwall.The utility model metallurgical roller can improve the sealing lip wear resistance, strengthens the intensity of annular spring and make the annular spring difficult drop-off with many sealings.
Description
Technical field
The utility model relates to a kind of metallurgical roller with many sealings.
Background technique
General metallurgical roller is with many sealings, first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip that comprises body, protrudes out from body and the steel band that is sheathed on the body periphery, the body and first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip are structure as a whole, first sealing lip outside is provided with open type annular spring groove, is arranged with an annular spring in the annular spring groove.Body and sealing lip are by 85 ° of A nitrile butadiene rubber sulfidization moldings.There is following shortcoming in this metallurgical roller with many sealings: 1, annular spring ejects in the annular spring groove of first sealing lip easily, influences sealing effect; 2,85 ° of A nitrile butadiene rubber hardness height are not easy distortion relatively, can keep whole sealing as body, but its stretchability are not so good, and wearability is poor, and therefore first sealing lip to the, five sealing lips by its making damage easily.
Summary of the invention
The purpose of this utility model provides a kind of metallurgical roller that improves the sealing lip wear resistance with many sealings.
For achieving the above object, the utility model is taked following design proposal: metallurgical roller is with many sealings, comprise body, first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip, and be sheathed on the steel band of body periphery, described first sealing lip outside is provided with open type annular spring groove, be arranged with an annular spring in the described annular spring groove, it is characterized in that: described body is formed by 85 ° of A nitrile butadiene rubber sulfurations, described first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip forms described body and described first sealing lip by 75 ° of A nitrile butadiene rubber sulfurations, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip is fixed together.
Be provided with the elasticity bin cure layer of silica gel of described annular spring of bonding and described annular spring groove inwall between described annular spring and the described annular spring groove inwall.
The utility model has the advantages that:
1, the utility model metallurgical roller is with many sealings, because wherein body is formed by 85 ° of A nitrile butadiene rubbers sulfurations, its hardness height is not easy distortion relatively, to keep whole sealing, better effects if.And first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip are formed by 75 ° of A nitrile butadiene rubbers sulfurations, therefore first sealing lip, second sealing lip, the 3rd sealing lip, the 4th sealing lip, the 5th sealing lip stretchability are good, be easy to deformation, effectively replenish wearing and tearing, prolong the working life of the utility model metallurgical roller with many sealings.
2, be provided with the elasticity bin cure layer of silica gel of bonding annular spring and annular spring groove inwall between annular spring and the annular spring groove inwall, so both strengthened the intensity of annular spring, and annular spring is come off.
