Geared compressed air starter

摘要

A geared compression air starter having a lead rotor, a driven rotor and a hollow shaft. A driven trunnion of the driven rotor engages with external teeth thereof into external teeth of the hollow shaft to connect the driven rotor with the hollow shaft. A freewheeling unit couples the hollow shaft with an axially displaceable engagement shaft so that the central axes of the engagement and of the hollow shaft can be positioned coaxially with respect to a central axis of the lead rotor. An engagement cylinder is connected with the engagement shaft by means of a piston rod which extends through the lead rotor, and the engagement cylinder is integrated into an end cover of the starter housing.
