This page is a continuation of How to Design a Flat Belt Drive [Step-by-step Tutorial] – Page 2.
Maximum velocity of belt (V) can be found out using the following equation:
d → Diameter of the smaller (driving) pulley in m
N1 → Speed of the driving pulley in rpm
There are two types of belts from which you can select from. They are:
- Dunlop “HI – SPEED” 878 g duck belting – Used in light and medium duty applications with high belt velocity.
- Dunlop “FORT” 949 g duck belting – Used in heavy duty applications with medium belt speeds.
For design power < 20 kW and belt velocity > 16 m/s, select Dunlop “HI – SPEED” 878 g duck belting.
For design power > 20 kW and belt velocity < 16 m/s, select Dunlop “FORT” 949 g duck belting.
Note: If you are using PSG design data book, refer page no. 7.52 (May 2012 reprint) for selecting the right flat belt.
The number of plies can be determined using the maximum belt velocity and the minimum pulley diameter from the following table.
Table (iv) – Determination of number of plies using maximum belt velocity and minimum pulley diameter
In the above table, the values given in italics are the values of minimum pulley diameter in mm.
Note: If you are using PSG design data book, refer page no. 7.52 (May 2012 reprint) for the above table.
