Abstract
A device for moving a hollow cam relative to a driving shaft includes an intermediate member between a drive member fixed to the driving shaft and a driven member fixe to the hollow cam. A cam ring in the form of an eccentric cam is disposed between the driving shaft and the intermediate member to maintain eccentric rotation of the intermediate member relative to the driving shaft. A driver mechanism controls the angular position of the cam ring.
Claims12
A device for moving a cam relative to a driving shaft, comprising:
- a driving shaft having shaft axis;
- a hollow cam concentric with said driving shaft, said hollow cam 22 having one end portion and opposite end portion;
- a drive member fixed to said driving shaft;
- a driven member fixed said hollow cam at said one end portion thereof;
- an intermediate member having an axis and disposed between said drive and driven members;
- a first coupling connecting said drive member with said intermediate member at a first position spaced from said shaft axis;
- a second coupling connecting said driven member with said intermediate member at a second position spaced from said shaft axis and spaced in an angular direction, with respect to said shaft axis, from said first position;
- said intermediate member having a central bore through which said driving shaft extends;
- a cam ring disposed within said central bore between said driving shaft and said intermediate member, said cam ring supporting said intermediate member.
