  • Patent number: 5971137
    Abstract: A cantilevered roller assembly for a conveyor system includes a non-rotating shaft, a sprocket, a roller, a sleeve, and a clutching spring. The non-rotating shaft has a first end with a first retention feature and second end with a second retention feature. The sprocket is rotatably disposed over the shaft. The roller is rotatably disposed over the shaft adjacent the sprocket. The sleeve is slidably and rotatably disposed over the non-rotating shaft. The sleeve has a first end in non-rotatable engagement with one of the sprocket and the roller on a first end and has a second end with an adjusting nut threadably disposed thereover. The clutching spring is axially disposed between the second end of the sleeve and the second end of the shaft. The clutching spring induces a clutching load between the sprocket and the roller. Rotation of the nut varies the clutching load between the sprocket and the roller.
