An apparatus for changing a rotating moving subject to a forward-moving subject and tilbagegaende

摘要

The invention relates to a device for converting a rotary movement into an oscillating movement frequently employed in agricultural implements, comprising a rotatable driving shaft, a fly-wheel rigidly secured thereto, an oscillatorily driven body adapted to oscillate about an axis crossing or intersecting the driving shaft axis and a coupling element pivoted to said body and journalled eccentrically in the fly-wheel; to adjusting in a simple manner the magnitude of the oscillating movement or the amplitude thereof, the device is adapted in that the bearing of the coupling element in the fly-wheel is arranged in a displaceable manner for varying the eccentricity and hence the amplitude of the oscillatory movement.
