is an easy to use pulley shaft calculation program provided to perform conveyor
pulley shaft size calculations. The program requires pulley and shaft dimensions
as well as conveyor belt tensions for starting and running.
This program is based on Australian Standard AS 1403
- Design of rotating steel shafts.

The program allows the user to open a new project file
and then quickly add new pulleys to the list. Enter dimensions and belt tensions,
select the shaft material and locking element types and then press calculate to
obtain the shaft sizes required at the locking element and bearing. You can quickly
and easily add new pulleys and rationalise the sizes required in order to minimise
capital and spares holding cost.
The main input data required is as shown in the images
Main Shaft Input Form
Easy to use inputs are provided on a compact form with
drop down boxes for materials, shaft sizes, locking elements etc. Choose a trail
diameter and press Calculate to see if the shaft you selected is OK. In addition
to AS 1403 requirements, the program also calculates the shaft deflection and provides
warnings if the deflection exceeds recommended values.
Easy to understand inputs prompt the user to enter the required data for drive shafts
so that overhung loads etc. can be calculated.
Stress Raising Correction Factors are calculated
AS1403 Stress Raising Correction factors are automatically
looked up and calculated for you
Lookup Data for Shaft Materials, Bearings, Locking elements is provided
