Abstract
Mécanisme convertisseur de mouvement rotatif en mouvement linéaire alterné ou vice versa conçu pour être appliqué dans bon nombre de machines utilisant actuellement des manivelles et des vilebrequins. Cette invention est formée d'une pièce coulissante (1) de p0ofil rectangulaire et avec des demi-cercles à ses extrémités, possédant sur sa largeur une voie intérieure perpendiculaire au profil en ligne droite à partir d'une centre du demi-cercle de la pièce coulissante jusqu'au centre de l'autre demi-cercle. Parallèlement à cette voie se trouve une surface extérieure dont la géométrie est définie conformément à la géométrie de surface de la roue (des roues) qui va (vont) glisser sur elle, de façon à rendre la transmission possible. La pièce coulissante décrit un mouvement de translation autour de la roue (des roues); leur contact, leur fixation ainsi que l'alignement à des fins de transmission sont assurés par un guide composite (2) formé d'un guide de fuite du mouvement rotatif, soutenu par l'arbre de la roue (des roues), en contact avec la pièce coulissante, accouplée parallèlement et au-dessus à un guide de mouvement rectiligne, dans lequel glisse la voie intérieure de la pièce coulissante.Rotary motion converter mechanism in alternating linear motion or vice versa designed to be applied in many machines currently using cranks and crankshafts. This invention is formed of a sliding piece (1) of rectangular profile and with semicircles at its ends, having on its width an inner track perpendicular to the profile in a straight line from a center of the semicircle of the piece sliding to the center of the other semicircle. Parallel to this path is an outer surface whose geometry is defined in accordance with the surface geometry of the wheel (wheels) which will (will) slide on it, so as to make transmission possible. The sliding part describes a translational movement around the wheel (wheels); their contact, their fixing as well as the alignment for transmission purposes are ensured by a composite guide (2) formed by a leakage guide of the rotary movement, supported by the wheel shaft (wheels), in contact with the sliding part, coupled parallel and above to a rectilinear movement guide, in which the internal track of the sliding part slides.
Description
ALTERNATE MOVEMENT OR VICE-VERSA
TECHNICAL FIELD
This invention relates to a converter mechanism of rotatory movement in linear alternate movement or vice versa, intended to be ""i applied in many machines, that uses presently cranks and crankshafts.
5 BACKGROUND ART
The conversion of the linear alternate movement in rotatory movement, .done presently by cranks and crankshafts has efficiency of
50%, not considering the loss due to friction. The conversion of the rotatory movement, done also by cranks and crankshafts, has irregular 10 speed and needs large areas for the cranks rotation and/or the crankshafts rotation, when linear alternate movements of large extent of motion is needed.
The present invention converts the linear alternate movement to rotatory movement with an efficiency much bigger, and converts the 15 rotatory movement in linear alternate movement with constant speed and occupies smaller area.
DISCLOSURE OF INVENTION
The converter mechanism of rotatory movement in linear alternate movement or vice versa is constituted for a slide piece that through a
20 composite guide works touching the wheel (s) that is in contact, describing a linear alternate movement, that makes possible a forces transmission with constant efficiency along of its extent of motion, being the variable efficiency only in the extremities of the slide piece, when it changes its direction.
25 % BRIEF DESCRIPTION OF DRAWINGS
The figure 1 constitutes the global representation of the present mechanism. The slide piece(l) coupled in the transmission wheel through the composite guide(2), which is coupled also in the wheel shaft.
The figure 2 constitutes a sideface view of the slide piece. The 30 figure 3 constitutes the composite guide composed by a trailing guide j' of rotatory movement and one guide of the rectilineal movement.
BEST MODE OF CARRYING OUT THE INVENTION The figure-2 constitutes a sideface view of the slide piece, that has the shape of a rectangle added by semicircles in its extremities 35 with the diameter equal to the height of the rectangle having its center at the extremities of the rectangle in the heigh h/2 of it.
The slide piece is emptied in its width from the center of the semicircle till this center of the other, creating it track for the
compos te gu e of the figure 3, be possible to cause the deslocation o the slide piece contacted at the wheel (s) in rotation.
This composite guide according to the figure 3 is constituted by a trailing guide of the rotatory movement(l) mounted around the shaft of the wheel (s) coupled with the present mechanism that direct a guide of the rectilineal movement coupled on it, above and parallelly. his guide of the rectilineal movement will act on the inside track of the slide piece. The composite guide has also the function to guarantee the adjustment of the slide piece at the wheel(s) contacted in it, in order that an efficient transmission be occured. This composite guide describes an intermittent rotatory movement of one turn to each complete movement of translation of the slide piece and in the di ection of this movement. The sideface of the slide piece of the opposite side where is the composite guide is destined to the coupling of pieces or gadgets, that makes possible the drive of the present .mechanism to the movement reception and force transmitted by it, being this side an extremity of the gadget shaft or machine in which the present mechanism is coupled.
INDUSTRIAL APPLICABILITY
Converter mecanism of rotatory movement in linear alternate movement or vice versa. In accordance with the invention has a wide industrial application, it is intended to be used in vehicles set in motion by linear alternate movement of the pedals, also to .the most part of machines endowed by cranks and crankshafts and also is proposed to motors.
OMPI
Claims
