Abstract
The utility model relates to a double-side driving roller, and the roller comprises a central spindle, bearing seats, two rollers, and a tooth-shaped belt pulley. Two ends of the central spindle are respectively provided with one bearing seat. Spindle bodies at two ends of the central spindle are fixedly disposed in bearing pieces of the bearing seats in a penetrating manner. The two rollers are fixedly disposed on the central spindle. The tooth-shaped belt pulley sleeves the spindle body, between the two rollers, of the central spindle. The tooth-shaped belt pulley is provided with a through hole along the axial direction. Two sides of the tooth-shaped belt pulley are respectively provided with a limiting ring. A blocking rod is disposed between the two limiting rings, and passes through the through hole of the tooth-shaped belt pulley. Two ends of the blocking rod are respectively in fixed connection with the two limiting rings. A plurality of gaskets are respectively disposed between the tooth-shaped belt pulley and the two limiting rings. The roller provided by the utility model is simple and reasonable in structure, and the rollers, the belt pulley and a rotating shaft are fixedly connected through expansion rings. A roller structure, the rollers and the belt pulley, which employ the above connection mode, can serve as independent spare parts, thereby reducing the cost of production and maintenance of rollers.
