Definitions

  • the invention relates to a crank mechanism.
  • a lever arm is firmly connected at one end to a shaft and at the other end of the lever with a rotatably mounted crank pin.
  • the counter pressure point (2) becomes the fulcrum of the lever (1).
  • the lever (1) describes a circle.
  • the lever passes through two points on this circular arc of 360 degrees:
  • the invention is based on the object of creating a new principle for the crank mechanism.
  • the crank mechanism has at least one rotatably mounted ring (21) with at least one rotating element (12) for the introduction of force and at least one operative connection (10) for constant transmission of force on the rotatable ring (21) to a lever (11).

Abstract

L'invention concerne une transmission à manivelle. Le principe usuel de fonctionnement d'une transmission à manivelle consiste à transmettre des forces, agissant de manière linéaire et développant une pression relativement constante, à un levier tournant à un angle de 360 degrés. Le point de contre-pression devient alors le point d'appui du levier, qui décrit un cercle. Sur l'arc de cercle fermé à 360 degrés, le levier passe par deux points, notamment un situé à 90 degrés et un situé à 270 degrés, où il est en mesure de transmettre le maximum de la force maximale qu'il a reçu. Ce qui revient à dire que ledit levier ne fonctionne pas de manière efficace sur 358 degrés de l'arc de cercle parcouru. L'invention vise donc à créer un nouveau principe de fonctionnement pour une transmission à manivelle. A cet effet, ladite transmission à manivelle comprend au moins un anneau (21) monté pivotant, lui-même doté d'au moins un élément de rotation (12) pour l'induction de la force et d'au moins une liaison active (10) pour la transmission permanente de la force à l'anneau (21) sur le levier (11).
