Definitions

  • the invention relates to the field of engineering, in particular to gears with a large gear ratio in the drives of various mechanisms.
  • planetary-cycloid and planetary-pinion gearboxes are known (see, for example, [1] - Litvin F.L. Gear theory, 2nd ed., M., 1968 and [2] - EV Muravyov. Planetary-pinion gearboxes and gearmotors. Gearboxes and drives. 2005, 4,5.).
  • the gear design of the analogue [4] with involute gearing is devoid of the disadvantages of cycloid and pinion gears, as it is made with a standard cutting tool and allows for a large gear ratio in small dimensions, and also has a simpler and more technological design.
  • the disadvantage of the analogue is the limited load capacity of the transmission at a given diameter, which does not allow to increase the maximum load on the transmission without increasing its diameter.
  • the disadvantage of the prototype is the limited load capacity of the transmission at a given diameter, which does not allow to increase the maximum load on the transmission without increasing its diameter.
  • the task of the invention is to eliminate the disadvantages of the prototype and increase the load capacity of the transmission without increasing its diameter.
  • cranks are installed on the drive shaft, offset from each other by an angle of 360 °: n or close to n him, where the number n for a given outer diameter of the gear is selected taking into account the maximum load, the diameters of the necks of the cranks are made decreasing sequentially from the middle necks to the edges, on the cranks, except for the central ones, compensating bushes with the same outer diameter are mounted with the possibility of removal, and the values of all transmission eccentricities are less than z times the specified radius of the centroid (initial circle) of the wheel with internal teeth.
  • the gear design is easier to design and allows the gears to be run in gear at the specified design diameter of the centroid and constant contact of the gear teeth in all gears.
  • Compensating bushings 16, 17, 18, 19 are installed during assembly sequentially on each neck of the corresponding crank 2, 4, 8, 11 and have the same outer diameter equal to the diameter of the neck of the middle crank 6, which allows the use of the same bearings to install the corresponding gears 3, 5, 9, 10 and make the inner diameters of the indicated wheels the same, and also unify and reduce the cost of the transmission structure.
  • the eccentricities of all elements, as in the prototype, are oriented during assembly in such a way as to ensure constant contact of the teeth of the wheels in all gears.
  • the work of the proposed gear transmission is as follows.
  • the gears 3, 5, 7, 9, 10 make a circular instantaneous progressive motion together with the shaft 1 so that when the shaft 1 is rotated, the gear wheel 12 with the internal teeth is rotated one revolution and with it the output shaft 13 by an angle proportional to the angle determined by the difference between the teeth of the wheels in the internal gearing, that is, in this case, by the angle corresponding to rotation by one tooth, thereby realizing a large gear ratio equal to the number of teeth z of the wheel with internal teeth.
  • the torque acting on the transmission is distributed to n teeth of the wheel with internal teeth and n teeth of different gears on the drive shaft, which allows to increase the bearing capacity of the transmission at a given diameter.
  • a new positive technical result is to increase the load capacity of the gear without increasing its outer diameter

Abstract

L'invention se rapporte au domaine du génie mécanique et concerne notamment des transmissions dentées ayant un rapport de transmission élevé dans des actionneurs de divers mécanismes. Le but de l'invention est d'éliminer les insuffisances du prototype et d'augmenter la capacité de charge de la transmission sans augmenter son diamètre. A cette fin, la transmission dentée de la présente invention comprend un arbre moteur avec des manivelles et des roues dentées montées sur les manivelles de manière à pouvoir tourner et présentant une excentricité, chacune ayant un nombre de dents de z-1, un arbre entraîné sur lequel est fixée une roue dentée avec des dents internes au nombre de z et dont l'axe de rotation est excentré par rapport à l'axe de l'arbre moteur et qui est fixé par des inserts excentriques à l'arbre moteur; sur l'arbre moteur se trouvent n manivelles décalées les unes des autres d'un angle de 360°:n ou presque, le nombre n lors d'un diamètre externe donné de la transmission étant choisi en tenant compte de la charge maximale, les diamètres des flancs des manivelles vont en diminuant successivement depuis les flancs médians vers les extrémités; sur les manivelles, sauf les centrales, sont disposés de manière amovible des inserts de compensation ayant un même diamètre, et les valeurs de toutes les excentricités de la transmission sont inférieures de z fois au rayon donné des barycentres (circonférence initiale) de la roue avec les dents internes.
