Title (EN) AN IMPROVED PAWL AND RATCHET CLUTCH AND METHOD
(FR) EMBRAYAGE A CLIQUETS ET A ROCHET AMELIORE ET PROCEDE
Abstract:
(EN) In a pawl and ratchet clutch (60) for an air turbine starter, a single torsion shaft (110) simultaneously forces each of a plurality of pawls (80) into engagement with the ratchet (65). The torsion shaft (110) is coupled to a cam (100) having radially extending arms each with an involute surface (105) in contact with an involute surface (86) on a radially extending member of one of the pawls (80). The torsion shaft (110) is co-axially disposed within the clutch so as to be readily accessible, which permits its twist to be adjusted without dismantling the starter.
(FR) Dans un embrayage à cliquets et à rochet (60) pour démarreur de turbine à air, un seul arbre de torsion (110) force simultanément chaque cliquet d'une pluralité de cliquets (60) à venir en prise avec le rochet. L'arbre de torsion (110) est accouplé à une came (100) dotée de bras s'étendant radialement et pourvus chacun d'une surface à développante (105) en contact avec la surface à développante (86) d'un élément s'étendant radialement d'un des cliquets (80). L'arbre de torsion (110) est disposé coaxialement dans l'embrayage de manière à être facilement accessible, ce qui permet de régler sa torsion sans démonter le démarreur.
