Band Brake Design Equations
Machine Design and Application
In the simple band brake a force is applied through a lever to a band wrapped part of the way around a drum. This produces tensions in the band and the difference between these multiplied by the drum radius gives the braking torque.
Where:
T= braking torque
P = braking power
F = applied force
N = speed of rotation
a = lever arm
r = drum radius
c = distance from belt attachment to fulcrum
