ABSTRACT:
A motion conversion apparatus 10 for converting continuous rotary motion into oscillatory, wide angle scanning motion is disclosed herein. The motion conversion apparatus 10 of the present invention includes a link 40 disposed to pivot about a pair of pivot points 33 and 35. The link 40 induces oscillation about a first axis of a member 11 coupled thereto thereby providing output oscillatory scanning motion. The apparatus 10 of the present invention further includes flywheel means 20 and 30 adapted to rotate about a second axis for causing the link 40 to pivot about the pivot points 33 and 35. A shaft 14 operatively coupled to the flywheel means 30 supplies input rotary motion.
