A drum pulley arrangement for conveyor installations, comprising at least one drum pulley hub having a central opening and a bearing having a central opening aligned with the hub opening. A drum shaft extends through the hub opening and terminates with an end within the bearing opening. A sleeve surrounds a portion of the drum shaft and extends through the hub opening and bearing opening, the sleeve having an interior opening of a diameter adapted to rest on the drum shaft at least in some region of the shaft end. A tightenable tapered clamping assembly is provided for each drum pulley hub, the assembly serving when tightened to couple the sleeve to the drum shaft and to the hub for transmitting a drive torque from the sleeve to the hub and to the drum shaft. |
