ABSTRACT:
A knife drive centrifugal pendulum vibration absorber for an agricultural combine harvester includes a wobble drive assembly 82 with an input drive shaft 132. A flywheel 188 is secured to the wobble drive input drive shaft 132. The flywheel has apertures 192 with walls that are arcs about an axis that are parallel to the axis of rotation of the flywheel 188. A roller 194 is inserted in each aperture 194. The rollers 194 roll along the walls of the apertures 194 in response to changes in the speed of rotation of the flywheel 188 and absorb vibrations induced in the drive shaft 132 by a reciprocating knife assembly 74.
