ABSTRACT:
A low drag air clutch for use in power transmission systems includes a rotating housing containing a clutch plate, a pair of spaced apart friction disks disposed on opposite faces of the clutch plate and a pneumatic operator assembly. One of the friction disks is fixedly retained in the housing. The other is coupled to the housing through arrays of helical splines which permit limited axial and rotational movement. The pneumatic operator assembly is disposed adjacent, engages and axially translates the movable friction disk. The clutch plate is coupled to a shaft member through arrays of helical splines. Activation of the pneumatic assembly engages the clutch elements. When deactivated, the rotation of the clutch elements and contact therebetween causes the helical spline arrays to urge the clutch plate and friction disks apart in order to eliminate partial mechanical coupling, i.e., drag, through the clutch.
