Abstract
A multi-functional cam system for controlling movement of a portion of a machine performing repetitive operations. A cam has a contour designed to control at least two different sequences of motion for a mechanism driven by the cam. The desired sequence of motion is obtained by registering the cam on its shaft to the position corresponding with that sequence of motion, then locking the position of the cam relative to the shaft. The mechanism that attaches the cam to the shaft includes a two-part hub, the two parts being axially clampable, a sleeve attached to the cam, the sleeve having a portion that is clamped between the hub parts, and a radially expandable locking device operating between the first hub part and the shaft. The clocking mechanism includes a sleeve tab extending axially from the sleeve, and at least two hub tabs extending radially from the first hub part. The sleeve tab and the hub tabs are designed and arranged to interfere with rotation of the sleeve relative to the first hub part and to locate one of the hub tabs adjacent the sleeve tab for each of the positions of the cam relative to the shaft.
