Flywheel sickle drive mechanism
A releasable, eccentric drive mechanism is described, comprising: a first shaft extending along a central axis and presenting a generally cylindrical portion; a second shaft extending along a reference axis substantially parallel to the central axis in offset relation to the latter and having a generally cylindrical portion; a drive member having structure defining an opening including a first, generally cylindrical region receiving over one half of the circumference of the first shaft portion and a second, generally cylindrical region receiving over one half of the circumference of the second shaft portion, the second region being in side-by-side relationship to the first region and in open communication with the latter, the first shaft portion and the second shaft portion each including a substantially flat wall section extending in a plane substantially perpendicular to a reference plane passing through the central axis and the reference axis, each of the wall sections being inclined relative to the central axis in complemental, flat engagement with each other; and means coupled to one of the drive member and the second shaft for urging the first shaft in a longitudinal direction generally toward the second shaft in order to bring the wall section of the first shaft into a position of flat, wedging contact with the wall section of the second shaft and in contact with the structure defining the opening in order to securely interconnect the first shaft, the second shaft and the drive member.
