Torsionally Stiff Clutch Pneumastar

The Pneaumastar is a torsionally stiff double cone friction clutch. The clutching components consist of 2 inner and 2 outer friction cones of which the inner ones are pneumatically pressed against the outer tapered friction faces vi a clutching cylinder. Rubber sleeve springs form the torsionally stiff portion of the clutch. As the clutching components are moved over the rubber sleeve springs during the actuation of the clutch, a wear-causing axial sliding movement between the various contacting parts is avoided. Pneumatic operation of the clutch enables speedy and precise manoeuvring which is prerequisite to qualify the clutch for use in marine applications.
