Centrifugal Clutch Design and Equations
Internally expanding friction shoes are held in contact, by the force due to rotation against the force of a light spring. The torque capacity increases as the speed increases.
Torque capacity (2 shoes)
ω = 2 π N
where:
m = mass of shoe
k = spring stiffness
x = deflection of spring
µ = coefficient of friction
F = radial force on drum
N = rotational speed
ω = angular velocity
