ABSTRACT:
A variable speed drive for a screw conveyor includes a mechanical adjustable variable speed belt drive and a torque-arm speed reducer. The belt drive is associated with the speed reducer through the combination of a mounting adapter and a mounting plate. A coupling shaft extends from the output discs of the belt drive through the mounting adapter and plate into driving relationship with the input of the speed reducer. The output shaft includes a mated splined output for receipt in a female splined input of the speed reducer. The speed reducer is outfitted with a CEMA standard flange for attachment to a screw conveyor with the screw conveyor drive shaft received in an output bore of the speed reducer. The mounting adapter and plate support the belt drive in a C-flow drive power configuration for minimizing space requirements, while avoiding damage to the screw conveyor mounting flange by controlling undesired bending forces thereat. The resulting variable speed drive for a screw conveyor is particularly useful in food industry applications where the ability to make fine adjustments of screw conveyor speeds is highly desirable.
