The image above represents diameter of driver pulley. To calculate the diameter of driver pulley, three essential parameters are needed and these parameters are Diameter of Driven Pulley (Db), r.p.m. of Driver Pulley (ra) and r.p.m. of Driven Pulley (rb).
The formula for calculating diameter of driver pulley:
Da = (Db x rb/ra
Where:
Da = Diameter of Driver Pulley
Db = Diameter of Driven Pulley
rb = r.p.m. of Driven Pulley
ra = r.p.m. of Driver Pulley
Let’s solve an example;
Find the diameter of driver pulley when the diameter of driven pulley is 12, the r.p.m of driven pulley is 24 and the r.p.m of driver pulley is 10.
This implies that;
Db = Diameter of Driven Pulley = 12
rb = r.p.m. of Driven Pulley = 24
ra = r.p.m. of Driver Pulley = 10
Da = (Db x rb/ra
So, Da = (12 x 24)/10
Da = 288/10
Da = 28.8
Therefore, the diameter of driver pulley is 28.8 m.
