Abstract
The invention relates to an in-furnace cantilever roll, in particular to an in-furnace cantilever roll with a good cooling effect, and belongs to the technical field of cantilever rolls. The cantilever roll comprises a base, a gear motor and a roll shaft, wherein the gear motor is fixed on the base; the output end of the gear motor is connected with the roll shaft. The roll shaft adopts a hollow shaft; a cooling water hole is formed in the interior of the roll shaft; a water outlet and a water inlet are formed in the tail end of the roll shaft; the water inlet of the roll shaft is connected with a water inlet connector; the water outlet of the roll shaft is connected with a water outlet connector; the right end of the roll shaft is connected with a roller. The cantilever roll has the advantages that the structure is simple, compact and reasonable, the cooling water hole is formed in the roll shaft, so as to cool the roll shaft, all components of the cantilever roll can be properly cooled, the service life is prolonged, and the maintenance cost is reduced.
Description
Technical field
The present invention relates to overhang roll in a kind of stove, overhang roll in the stove specifically with good cooling effect, belongs to overhang roll technical field.
Background technology
In stove, overhang roll is the visual plant for being transported to by the steel billet on feeding skid in stove, and it should carry the weight of steel billet, completes conveying again in hot environment.
In prior art, in stove, the roll shaft of overhang roll is mostly supported by the bearing and bearing block that are symmetricly set on roll shaft two ends, in the course of the work, near the parts of high-temperature area side, very easily cause lubricating oil to dryout by temperatures involved, bearing block burns out, or cooling water pipe explosion, bearing locking etc., bearing is changed in regular stopping production of for this reason having to, and has both affected normal production, and has increased maintenance cost and human resources again.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus overhang roll in a kind of stove is provided, in roll shaft, be provided with cooling water hole, each parts of overhang roll can be made well to be cooled, improve service life, reduce maintenance cost.
According to technical scheme provided by the invention, in stove, overhang roll comprises base, reducing motor and roll shaft, base is fixed clutch shaft bearing seat and the second bearing block, it is characterized in that: in clutch shaft bearing seat, be provided with clutch shaft bearing, the second bearing is provided with in second bearing block, roll shaft is through clutch shaft bearing seat and the second bearing block, and the clutch shaft bearing passed through in clutch shaft bearing seat and the second bearing common support in two bearing bracket; Reducing motor is fixed on base, and reducing motor output connects roll shaft; Described roll shaft is hollow shaft, and inside is provided with cooling water hole, and roll shaft end is provided with delivery port and water inlet, and the water inlet of roll shaft connects water supply connector, and the delivery port of roll shaft connects water out adapter, and roll shaft right-hand member connects roller.
Further, water supply connector is connected on the water inlet of roll shaft by the first locking nut locking.
Further, water out adapter is connected on the delivery port of roll shaft by the second locking nut locking.
Further, clutch shaft bearing is self-aligning roller bearing.
Further, the second bearing is self-aligning roller bearing.
Compared with the prior art the present invention has the following advantages:
