Question

How Does A Centrifugal Clutch Work In A Chainsaw? Can anyone explain me?

Answer 1

The centrifugal clutch found on a chainsaw is a safety device that disengages the engine at high revs. The centrifugal clutch incorporates a pulley and weights that rotate with the engine shaft. At the end of the shaft is a device that releases the clutch when the engine reaches a predetermined rpm. When the clutch is engaged, the pulley on the pulley on the clutch connects the engine to the saw blade. The centrifugal clutch is used in conjunction with a kickback brake on many chainsaws. The primary function of the kickback brake is to protect the operator from kickback by cutting through on the kickback on the flyback on the return stroke.

Answer 2

A centrifugal clutch works on the principle of centrifugal force. The clutch consists of an inner hub with engaging teeth and an outer hub with disengaging teeth. The teeth on the inner hub are narrower than the teeth on the outer hub. As the blade of the saw turns, it pushes on the inner hub, creating centrifugal force. This disengages the inner tooth on the outer hub, allowing the blade to spin without turning on the motor. The centrifugal clutch on chainsaws is controlled by a trigger on the saw's handle. When the blade hits something, the centrifugal force is overcome by the force of the object hitting the blade. This triggers the centrifugal clutch so the engine turns off.
