Definitions

  • the invention is a mechanism that is designed to create an alternative to the existing mechanisms that convert rectilinear motion to circular motion or circular motion to rectilinear motion.
  • the invention is an alternative mechanism that is designed to be used directly or indirectly in the mechanisms that can be controlled by any kind of drive system such as manual, electrical, pneumatic, hydraulic etc.
  • the systems converting rectilinear motion to circular motion or circular motion to rectilinear motion are used extensively, especially in all the processing machines, test machines, automotive, automation, robot technologies for power, force, or motion transfer.
  • the actuator is an electric motor
  • these systems are widely used in the cases where the circular motion received needs to be transformed into a rectilinear motion at the desired speed and direction, or if the motion element is a pneumatic or hydraulic cylinder causing rectilinear motion, where the rectilinear motion needs to be converted into a circular motion.
  • the first one of the existing systems is the gear systems, which is also known as racks.
  • gear systems which is also known as racks.
  • a pinion gear and a gear rack transfer the force, motion, moment, or rotation. If the circular motion is requested to be converted into rectilinear motion, the rotational motion on the pinion gear is transferred to the gear rack that is matched and housed in a body, and the motion is converted to rectilinear motion with a ninety- degree direction change. Similarly, the rectilinear motion from the gear rack is converted into circular motion via the pinion gear.
  • Rack gears are overcosting systems because it is compulsory to produce the teeth via special machines with very precise tolerances.
  • the most economical and easily producible form is the spur gear structure of the teeth of both the pinion gear and gear rack. Due to the fact that this structure is noisy and not very sensitive, this disadvantages can be eliminated by producing gear structures as helical gear or conical gear; however, in this case, the production of the gears increases the costs quite much.
  • the above figure shows a rack mechanism with spur teeth.
  • the system is operated when the force and motion could not be converted on the same axis, but only the circular motion is perpendicular to the rectilinear motion.
  • the third one of the existing systems is the threaded rod mechanisms.
  • These mechanisms have various structures and names according to the screw thread form.
  • the most common screw form is known as the trapezoid screw mechanism that has a trapezoidal form.
  • Circular motion or rectilinear motion is performed by means of balls or various bearing elements that are placed in the same helical channels opened inside a slot that can be called as sleeves or nuts with helical channels that are opened on a spindle.
  • the mechanism of invention will work with less friction, it will eliminate the need for the motors consuming less energy, thus, there will be less energy consumption. Also, the mechanism will operate in the areas where it is sufficient to be operated at lower speeds without a need for any bearing system. Special bearings can be used in special cases such as high power transfer and high-speed operation as in other systems.
  • Helical Channels (2) are located on the Helical Channeled Pipe (1) and the Drive Pin (5) is passed inside the Helical Channels (2) via the Helical Channeled Pipe.
  • the Drive Pin (5) is assembled in such a way that both ends form a linear bedding and both ends of the Helical Channeled Pipe (1) protrudes from both sides.
  • the Helical Channeled Pipe (1) can be circularly bedded by means of the Upper rod of the Helical Channeled Pipe (3) and the Lower Rod of the Helical channeled pipe (4) at both ends.
  • the Drive Pin (5) which is located in the Helical Channels (2) and is linearly bedded from both ends, moves forward or backward according to the left or right rotational motion.
  • the Helical mechanism will convert the circular motion into rectilinear motion and an object that is attached to the Drive Pin (5) will have performed its rectilinear motion.

Abstract

L'invention concerne un mécanisme qui est conçu pour créer une alternative aux mécanismes existants qui convertissent un mouvement rectiligne en un mouvement circulaire ou un mouvement circulaire en un mouvement rectiligne. L'invention peut être conçue pour être utilisée directement ou indirectement dans les mécanismes qui peuvent être commandés par n'importe quel type de système d'entraînement, tel qu'un entraînement manuelle, électrique, pneumatique, hydraulique etc.. L'invention concerne un mécanisme qui peut être diversifié conformément au lieu d'utilisation et ne nécessite aucun palier supplémentaire à faible vitesse et petites charges, et dont les procédés de production sont plus économiques par rapport à ceux des mécanismes fabriqués avec divers engrenages et broches hélicoïdales. En particulier, ce mécanisme constitue une alternative aux mécanismes existants, comprenant les avantages d'économie et d'assemblage facile, en tant que mécanisme qui va activer un mouvement rectiligne en un mouvement circulaire ou un mouvement circulaire en un mouvement rectiligne dans les technologies d'aujourd'hui d'automatisation et de robotique croissantes.
