Abstract: A pneumatic stepper motor weight actuator (7) captures the advantages of polymeric harmonic gears while occupying less space and eliminating the problems associated with air entrapment in the stator grooves (31, 49). Air entrapment is eliminated by providing orificed air passages (47) from the bottom of the longitudinal stator grooves (31) to the center stator hole (45). Advantageously, the actuator (7) includes a rigid gear (23) comprising a toothed polymeric sleeve (61) adhesively bonded inside a metal cup (63).

Abstract: A two-speed stepper actuator (10) for rotationally driving a power nut (24) to adjust a slice lip spindle (20) linearly. A clamp for power nut (24) includes a bushing plate (32) driven by drive solenoid (D) which is mounted for rotation relative to power nut (24). A lever (40) is pivotally mounted on the bushing plate (32) and includes an eccentric locking cam surface (50) shaped for selective clearance of nut (24) when in the center or number 2 position and clamping engagement of nut (24) when in the opposite extreme 1 and 3 positions. A first amount of rotation of the lever (40) about its pivotal mounting (48) on said bushing plate (32) engages and locks lever end cam surface (50) against nut (24) and a second and additional rotation of the lever (40) then drives the nut (24). Three position solenoids (L) and (D) drive the bushing plate (32) and lever (40) independently and at different speeds due to an accommodation by spring (36) on pusher rod (34) of solenoid (L).

Abstract: Actuateur de poids entraîné par un moteur pas à pas pneumatique (7) utilisant les avantages des engrenages harmoniques polymères tout en occupant un espace plus restreint et en éliminant les problèmes liés à l'introduction d'air stagnant dans les rainures du stator (31, 49). On élimine le problème de la prise au piège d'air en formant des passages à trous pour l'air (47) qui s'étendent depuis le fond des rainures longitudinales (31) du stator jusqu'au trou central (45) du stator. L'actuateur (7) comprend avantageusement un engrenage rigide (23) comportant un manchon polymère denté (61) collé à l'intérieur d'un élément creux en métal (63).
