Abstract

Centrifugal clutch consists of a mild steel drum and a single piece cast Fe moulded rotor. The rotor comprises a cross-piece diametrically dispersed having a central hole, two weight pieces on each side of the cross-piece having a circular segment extending at least 90 degrees and having a dia. of at least 25% dia. of the rotor, and thin elastic pieces connected to opposite ends of the cross-piece and having circular form extending 30-50%. The elastic pieces ensure that the weight pieces are withdraw from the drum circumference when the rotor speed is below a critical speed.
