Helix delta-D Pulley Shaft Design to AS1403 Standards

Helix delta-D 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.
A copy of the Australian Standard AS1403 may be obtained from http://www.saiglobal.com

Click the following link to see a sample calculation report based on the worked example given in AS1403 Appendix F on page 45 - Worked Example Calculation AS 1403 (PDF file 89kb)

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 below.

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.

Drive Details Input Form

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 automatically

AS1403 Stress Raising Correction factors are automatically looked up and calculated for you

Lookup Data for Shaft Materials, Bearings, Locking elements is provided

Quality Control

Disclaimer

This program has been developed specifically for the design of Conveyor Pulley Shafts and is not intended as a general shaft design tool. It must be used by qualified persons experienced in pulley shaft design as the use of the program, and the interpretation of the calculation results, requires an understanding of the shaft design process. The shaft sizes calculated are dependent on the dimensions entered and input data for belt tensions as well as the material properties and stress raising factors used and no guarantee or warranty is given to users of this program.
