Bucket elevator gearbox design takes into consideration the special requirements of bucket elevators in the grain and bulk handling industry.
Bulk bucket elevators are vertical bulk materials handling equipment used in the transfer of grain and fertiliser between storage systems. There are differing styles, but the primary elevator is known as the Centrifugal Discharge Elevator. The very nature of bucket elevator design requires a relatively high speed, which creates specialist demands for the mechanical power transmission required to drive them.
Bucket Elevator Gearbox
Gearboxes for bucket elevator applications have certain design requirements:
- Relatively high speed for standard operation
- Auxiliary drive for inching (positioning)
- Shrink disc on hollow output
Bevel-helical designs have become the preferred choice over the years, with either a wormbox or secondary bevel-helical as the gearbox used for low-speed positioning duties.
