Patent ID: 8783177

Claim:
A system for oscillating a working roller disposed between first and second gudgeons slidably and rotatably disposed on a non-rotatable shaft, comprising: an oscillating assembly disposed for oscillation and rotation on said shaft; and an oscillation mechanism disposed for rotation on said shaft and connected to said oscillating assembly, wherein said oscillation mechanism comprises: at least one tie rod connecting said first and second gudgeons; at least one oscillation pin connected to said tie rod and extending radially inwards from said tie rod toward said shaft, an oscillation cam rotatable on said shaft and including a first timing element; wherein the oscillating assembly is oscillated by the oscillation pin in cooperation with the oscillation cam; and wherein said oscillation mechanism includes a reduction transmission having a plurality of timing elements rotationally connected in an arrangement to yield a desired rotation ratio between said oscillating assembly and said oscillation mechanism.
