T1 = Tension in the tight side of the belt
T2 = Tension in the slack side of the belt
V = Velocity of the belt in m/sec.
= πDN/60 m/sec, D is in meter and N is in RPM
P = Maximum power transmitted by belt drive
The effective tension or force acting at the circumference of the driven pulley is the difference between the two tensions (i.e., T1 – T2)
Effective driving force = (T1–T2)
Work done per second = Force X Velocity
= F X V N.m
= (T1–T2)X V N.m
Power Transmitted = (T1–T2).V/1000 Kw
(Here T1 & T2 are in newton and V is in m/sec)
1. Torque exerted on the driving pulley = (T1–T2).R
Where R1 = radius of driving pulley
2. Torque exerted on the driven pulley = (T1–T2).R2
Where R2 = radius of driven pulley.
