Abstract
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.

A device for converting a rotary movement into an oscillating movement comprising a rotatable driving shaft, a fly-wheel rigidly secured thereto, an oscillatorily driven body oscillating about an axis crossing the axis of the driving shaft and a coupling element pivoted to said body and journalled eccentrically in the fly-wheel, the bearing of the coupling element in the fly-wheel being displaceably arranged for varying the eccentricity and hence the amplitude of the oscillatory movement, and the fly-wheel bearing of the coupling element being eccentrically accommodated in a supporting member, which can be disposed in more than one angular position in the fly-wheel.
A device for converting rotary motion to oscillating movement comprising, in combination:
- a drive shaft rotatable about a first axis, and a flywheel fixed to said drive shaft;
- a driven shaft rotatably supported for oscillating movement about a second axis perpendicular to said first axis, said first and second axes intersecting at a point spaced from said flywheel;
- a coupling member pivotally connected at one end to said driven shaft about a third axis which is perpendicular to said first and second axes and intersects therewith at said point, and bearing means journalling the other end of said coupling member in said flywheel at a position radially displaced from said first axis whereby said coupling member extends from said point to said position at an acute angle with respect to said first axis, said bearing means comprising a bearing receiving said other end of the coupling member and a support member for said bearing and carried by said flywheel;
- and
- means for adjusting said support member relative to said flywheel to vary the radial disposition of said bearing and thereby change the location of said position.
