Screw Conveyor Drive Arrangements
KWS utilizes a variety of drive arrangements and gear reducer manufacturers. Each drive arrangement shown below provides unique advantages for specific applications. KWS designs each drive with a minimum of 1.4 service factor (Class II) to ensure long life and reduced maintenance. Spare parts are available through authorized power transmission distributors all across the U.S. and Canada.
Screw Conveyor Drive
Screw conveyor drives are the most common drive arrangement utilizing a screw conveyor adapter that bolts to the trough end of a screw conveyor. The gear reducer is flange mounted directly to the trough end to provide a simple, rigid assembly.
Bulkhead
Bulkhead trough ends are used in applications where there is a need to locate the drive away from the trough end. When conveying bulk materials at high temperatures, the drive must be located away from the source of heat to prevent drive failure. Also, if a special shaft seal is required, bulkhead trough ends provide clearance for the seal. Flanged gland, split gland and mechanical seals are typically used with bulkhead trough ends.
Torque Arm
Torque arm trough ends allow shaft-mounted reducers to ”float” to handle shaft run-out. A pillow block bearing is required to support the screw when using a torque arm trough end. Similar to bulkhead trough ends, torque arm trough ends are used in special applications where there is a need to locate the drive away from the trough end. Flanged gland, split gland and mechanical seals are typically used with torque arm trough ends.
