A clutch assembly for a UV module shutter, comprises a shutter shaft, a shutter drive arm, a clutch plate, at least one ball, a clutch thrust washer, and a spring assembly. The shutter shaft has a flange, the flange having a plurality of radially positioned flange detents. The shutter drive arm includes a drive pin, a drive arm cavity, and a receiver slot opening into the drive arm cavity, the drive pin disposable in a drive slot of a shutter end cap. The clutch plate may be disposed in the clutch plate cavity, may have a tab disposed in the receiver slot and a plurality of clutch plate detents. Each of the ball(s) may extend from one of the flange detents and may be partially disposable in one of the clutch plate detents. The spring assembly may exert a bias against the clutch plate and the thrust washer. The shutter shaft may extend through the shutter drive arm, the clutch plate, and the clutch thrust washer.
A clutch assembly for a UV module, comprising:
A method of assembling a clutch assembly for a UV module, comprising:
A method of configuring a UV module clutch between an engaged position and a disengaged position, the clutch comprising a shutter shaft, a plurality of balls, a clutch plate, and a spring assembly, the shutter shaft having a shutter shaft flange, a plurality of shutter shaft detent holes present in the shutter shaft flange, the detent balls disposed in, and extending from, the shutter shaft detent holes, the clutch plate having a plurality of clutch plate detents, each clutch plate detent having a diameter smaller than a diameter of each of said balls, the spring assembly axially biasing the clutch plate and balls against the shutter shaft flange, the method comprising exerting a breakpoint torque on the shutter shaft flange or the clutch plate, thereby displacing the clutch plate from the balls and thereby configuring the clutch from the engaged position to the disengaged position,
