ABSTRACT:
A pawl and ratchet clutch and an air turbine starter having such a clutch is provided in which a single, torsion shaft simultaneously forces each of a plurality of pawls into engagement with the ratchet. The torsion shaft is coupled to a cam having radially extending arms with involute surface portions. Each pawl has a radially extending member that has an involute surface. The pawls and cam are disposed within the clutch so their respective involute surfaces are in rolling contact with each other. The torsion shaft is coaxially disposed within the clutch so as to be readily accessible, which permits its twist to be adjusted without dismantling the starter.
