conveyor drive assemblies

Continental screw conveyors rely on drive assemblies.

Continental Conveyor Ltd. has succeeded for decades with high-end industrial material-handling systems and related products. The lineup includes screw conveyors – which rely on such accessories as conveyor drive assemblies to function properly. The Continental team offers various combinations and types of drives for screw conveyors, both inclined and vertical.

Screw-conveyor drives, shaft-mounted reducers, and gear-motor drives are among the frequently used drives and mechanical arrangements available for these drive assemblies.

Blending reducer output shaft

A screw-conveyor drive is a kind of drive assembly that includes a modified shaft-mounted reducer complete with a V-belt drive and motor mount in an integral unit. This assembly blends the reducer output shaft, conveyor thrust bearing, end seal, and adapter flange for mounting integrally to the trough end. The electric motor can be mounted in either the horizontal or vertical plane, adding to the versatility of these Continental conveyor drive assemblies.

Essentially very similar to a screw-conveyor drive, a shaft-mounted reducer requires the use of a thrust bearing, a drive shaft, and a seal assembly. As with a screw-conveyor drive, the motor mount can be integrally blended with the reducer unit and transmit power through a V-belt drive. Shaft-mounted reducers are usually employed in tasks that need special sealing arrangements on the conveyor shafts, such as packed gland seals, or transmission of very high horsepower that is outside the parameters of the screw-conveyor drive.

Yet another kind of conveyor drive assemblies from the Continental crew is gear-motor drives. Each one is used to power a conveyor through either direct, low-speed couplings mounted to the conveyor drive shaft or through the roller-chain drive. The couplings are usually mounted on scoop bases attached to the trough ends, while the roller-chain drive is mounted directly on top of the conveyor or an adapter base, or a base plate beside the conveyor. Gear-motor drives are common when users are transmitting high horsepower, or when variable-speed gear motors are used to change metering screws’ feed rates.

Other methods of driving screw conveyors: variable-speed DC motors with SCR rectifiers; hydraulic drives; and variable pitch sheaves.
