Abstract
The utility model relates to the technical field of rolling conveying devices, in particular to an anti-falling rubber covered roller which comprises a roll shaft, a roller body and a rubber skin. The roll shaft is located on the axis of the roller body, the rubber skin wraps the outer surface of the roller body, locking bolts are arranged on the roller body, and screw holes and blocking plugs are arranged on the rubber skin. The locking bolts are connected to the circumferential face of the roller body through threads and are inserted into the screw holes, so that the rubber skin and the roller body are tightly attached, the rubber skin is prevented from being thrown away due to centrifugal force generated by high-speed rotation, the rubber skin is effectively prevented from swelling and falling, springs can exert continuous and stable elastic pre-tightening force to counteract centrifugal force, the rubber skin is prevented from loosing, the overall performance and using effect of the rubber covered roller are improved, and service life is prolonged. Friction bars are arranged on the outer surface of the rubber skin, sliding friction between the rubber skin and the outside is changed to rolling friction, abrasion is lowered, and rolling conveying efficiency is improved.
Description
Technical field
The utility model relates to roll extrusion load transfer device technical field, especially a kind of anticreep rubber covered roll.
Background technology
In industries such as metallurgy, electric power, mine, printing, weaving, printing and dyeing, chemical industry, rubber covered roll is widely used.Rubber covered roll, also referred to as rubber coated roll shaft, is made columniform gyro-rotor with metallic material, is then coated one deck elastomeric material on the surface of cylindrical gyro-rotor.At present, the rubber covered roll of producing is both at home and abroad all at the outside rubber that directly covers of smooth roller, vulcanizes, when the rubber covered roll of this structure uses at the scene, especially in the working environment of High Rotation Speed, produce larger centnifugal force, rubber cover is outwards thrown away, and easy and roller departs from, produce bulge shelling phenomenon, and come off under long-term extruding, affect service life and the result of use of rubber covered roll, in addition, rubber cover smooth surface easily produces cliding friction, affects roll extrusion laser propagation effect.
Utility model content
Easily come off in order to overcome existing rubber covered roll rubber cover, service life is short, and cliding friction is large, affects the deficiency of roll extrusion laser propagation effect, and the utility model provides a kind of anticreep rubber covered roll.
The utility model solves the technical scheme that its technical matters adopts: a kind of anticreep rubber covered roll, comprise roll shaft, roller and rubber, roll shaft is positioned on the axis of roller, and rubber is wrapped on the outside face of roller, roller is provided with lock bolt, and rubber is provided with screw and shutoff plug.
According to another embodiment of the present utility model, further comprise that lock bolt is inserted in screw, bottom is threaded on the periphery of roller.
According to another embodiment of the present utility model, further comprise that screw is two-stage hierarchic structure, higher level aperture is large compared with subordinate aperture.
According to another embodiment of the present utility model, further comprise that the top cover of lock bolt has pad and spring.
According to another embodiment of the present utility model, further comprise that pad is pressed on the interior step of screw, spring is pressed on pad.
According to another embodiment of the present utility model, further comprise that shutoff plug is embedded in the aperture of screw.
According to another embodiment of the present utility model, further comprise that the outside face of rubber is provided with fricting strip.
The beneficial effects of the utility model are, lock bolt is threaded on the periphery of roller, lock bolt is inserted on rubber in the stair-stepping screw of two-stage, be stuck in by pad on the interior step of screw rubber is applied to coupling mechanism force, rubber and roller are fitted tightly, centnifugal force the casting aside rubber of avoiding High Rotation Speed to produce, effectively prevent the bulge of rubber, come off, the spring being pressed on pad can be implemented continual and steady elasticity predetermincd tension, offset centnifugal force, prevent that rubber is loosening, shutoff plug is embedded in the aperture of screw, combine together with screw, both lock bolt had been encapsulated in to rubber inside, integraty and the planarization on rubber surface are ensured again, overall performance and the result of use of rubber covered roll are improved, extend service life.The outside face of rubber is provided with fricting strip, can change rubber and extraneous cliding friction into friction of rolling, has both reduced wearing and tearing, has improved again roll extrusion transmission efficiency.
