ABSTRACT:
A pneumatic clutch/brake comprising an input shaft having a structure defining a pneumatic conduit. A pair of pistons having opposed faces is drivably connected with the input shaft and is axially movable along and with respect to the input shaft. A totally enclosed housing is rotatably carried and supported by the input shaft. A method of clutching/braking in a clutch/brake zone from a rotating power shaft while simultaneously preventing any matter including contaminants from entering or leaving the clutch/brake zone. The method comprises the steps of securing a shaft having a pneumatic passageway to the power shaft, and mounting a pair of opposed pistons on the shaft in the clutch/brake zone so that the pistons can be rotated by the shaft and axially movable thereon. The clutch/brake zone including the pair of opposed pistons are totally enclosed by rotatably supporting a totally enclosed housing on the shaft such that the totally enclosed housing restricts or limits the axial movement of the pistons while simultaneously preventing any matter including contaminants from entering or leaving the clutch/brake zone.
