Shaft Design - conveyor drive pulley

Shaft example 2012 Shaft Design - conveyor drive pulley A Problem description A shaft has to be designed to suit a drive pulley of a conveyor belt system. The overall dimensions are shown on the diagram below. From experience the customer requires that the inclination of the shaft at the keyways be no more than 1/1200 (tangent or radians). From past installations it has

CONVEYOR PULLEY SELECTION GUIDE

Conveyor pulleys are designed for use on belt conveyor systems as a means to drive, redirect, provide tension to, or help track the conveyor belt. Conveyor pulleys are not designed for the same application intent as conveyor rollers. Conveyor rollers are designed to be used in the bed of a conveyor as a support for the conveyed product and often under the conveyor bed in the return section to support the return side of the conveyor belt.

Comparison of shaft designs for conveyor pulleys and idler ...

The shaft for pulley and the idler must be designed to handle stress and deflection criteria. The deflection criteria are needed to provide ample life for the product carried by the shaft, not necessarily the shaft itself. This is and will remain the case unless one uses a connection system that will align itself dynamically to the shaft. References Conveyor Equipment Manufacturers Association ...
