Abstract
A clutched driven device () having a clutch assembly () with a first rotary clutch portion (), a second rotary clutch portion (), a bearing (), a wrap spring () and an actuator (). The first rotary clutch portion has an interior clutch surface (). The first and second rotary clutch portions are rotatably disposed about a rotary axis () of the clutched driven device. The bearing is received between the first and second rotary clutch portions and supports the first rotary clutch portion for rotation on the second rotary clutch portion. The wrap spring is disposed radially inwardly of the bearing and has a plurality of helical coils () that are received against the interior clutch surface. The actuator is configured to selectively initiate coiling of the wrap spring to cause the helical coils of the wrap spring to disengage the interior clutch surface to a predetermined extent.
