Definitions

  • the invention relates to mechanical engineering, namely to gears for communicating rotational motion, and can be used on vehicles, in mechanical and electromechanical devices, where stepless speed control is necessary.
  • the torque from the driving cone to the driven one is transmitted through a ferromagnetic fluid supplied to the gap by means of a dispenser.
  • a dispenser moves along the generatrix of the cones and when the angle of its inclination changes, the ferromagnetic fluid solidifies and hard contact occurs between the cones. This changes the gear ratio of the variator.
  • the conical variator lacks reliable mechanical engagement of the shafts and automatic change of the gear ratio. But this transmission, due to its kinematic features, does not provide reversal. In addition, due to a decrease in the reduced radius of curvature of the contacting elements, the contact compression stresses increase, which leads to friction losses. In addition, the device has a complex structure and large dimensions.
  • the variator contains a driving cone with an outer working surface, a conical roller, selected from separate disks having a conical surface on the periphery, an intermediate cylindrical roller and a driven cone.
  • the driving cone rotates all the disks of the conical roller, which rotate at different angular speeds.
  • the cylindrical roller moving along the generatrix of the conical roller, comes into contact with part of the discs and transmits rotation to the driven cone.
  • the variator control range can be changed not only by changing the length of the generators of the drive and driven taper shafts, but also by changing the angles at the apex of the cones individually or simultaneously.
  • the device implements the principle of multithreading power transmission from the drive shaft to the driven shaft without increasing the size of the variator. In this case, it becomes possible to unload the shafts and their bearings from radial loads.
  • the closest in design and technical nature to the proposed technical solution is the variator presented in the patent of Ukraine N ° 54794, IPC 7 15/00, published March 17, 2003, Bull.JN ° 3, taken by the author as a prototype.
  • the variator comprises a conical drive shaft made in the form of a cylindrical rod, a drive shaft, an intermediate roller and a reverse shaft with a friction element freely mounted on it and in contact with the drive shaft.
  • the variator works as follows. The torque from the drive shaft through the friction element and the intermediate roller is transmitted to the driven shaft. When moving the roller along the axis of the driven shaft, the gear ratio of the variator is changed. If it is necessary to change the direction of movement, the reverse shaft enters the work.
  • This solution in comparison with the known, due to the implementation of the drive shaft in the form of a cylindrical rod, radically simplifies the design of the variator.
  • the presence of a reverse shaft with a friction element that is in contact with the drive shaft ensures its versatility.
  • the device can be used as a friction clutch or gearbox, as well as a starting and protective device.
  • the driven shaft can be made with grooves on its generatrix or worm shaft, depending on the purpose of use.
  • the disadvantage of the prototype is the difficulty of turning on the reverse mode associated with the need to tap the driven shaft from the reverse shaft, that is - a structural inconvenience.
  • An important factor in the operation of the variator - disabling the transmission of rotation to the driven shaft - is absent in the described variator.
  • the basis of the invention is the task of creating a variator, characterized by simplicity, compactness and versatility.
  • the problem is solved due to the fact that in the variator containing a conical drive shaft, a driven shaft with an intermediate roller mounted with axial movement and a reverse shaft with a friction element freely mounted on it, kinematically connected with the conical drive shaft, according to the invention, the drive shaft made in the form of a truncated cone.
  • the invention is illustrated in the drawing, where figure 1 shows the kinematic diagram of the variator.
  • the variator contains a drive shaft 1 in the form of a truncated cone, a driven shaft 2 with an intermediate roller 3 mounted axially movable, and a reverse shaft 4 with a friction element 5 kinematically connected with the conical drive shaft 1.
  • the principle of operation of the variator is as follows. The torque from the drive shaft 1 is transmitted through the intermediate roller 3 to the driven shaft 2. By moving the intermediate roller 3 along the axis of the driven shaft 2, the rotation speed of the driven shaft 2 is changed. If necessary, the reverse mode is activated. The friction element 5 is turned on. The torque of the drive shaft 1 transmit to element 5 and through the intermediate roller 3 to the driven shaft 2.
  • a prototype variator manufactured in accordance with the proposed technical solution has successfully passed the tests, confirming its technical and economic efficiency.

Abstract

L'invention appartient au domaine des constructions mécaniques et concerne plus particulièrement des transmissions destinées à communiquer un mouvement rotatif; elle peut s'utiliser dans des véhicules de transport et dans des instruments électromécaniques qui nécessitent une variation de vitesse sans pas. Selon l'invention, le variateur comprend un arbre conique d'entraînement, un arbre entraîné muni d'un rouleau intermédiaire, monté avec possibilité de déplacement axial, et un arbre d'inversion comportant un élément de frottement librement installé. L'arbre entraîné se présente comme un cône tronqué. L'invention permet d'obtenir une structure moins complexe et de construire un variateur simple et universel.
