worm gear / shaft
SUMITOMO (SHI) Cyclo Drive Germany GmbH
Sumitomo centrifugal gear drives are ideal for all types of screen centrifuges and decanters with screw conveyor for solids transport.
A wide variety of options, an extensive product range, high gear ratios, high shock resistance and the possibility of customized special designs make these the most widely used gear drive system for centrifugal applications.
Sumitomo centrifugal gear generate the differential speed between the bowl and the conveyor and the torque on the screw. The precise balanced housing is connected to the drum and rotates with the drum speed.
The output shaft of the centrifuge is connected to the worm gear, and transmits the torque required for the transport of solids. The drive shaft can be kept with a torque arm or operated with a back drive motor, to produce the required rotational speed difference.
