Definitions

  • the present invention relates to devices for transforming rotary motion into oscillatory motion using three parallel shafts and five spur gears, wherein a pair of gears is fixed to the two shafts each and meshed with each other operating as "link gears" and another a pair of gears is also fixed to the said two shafts, respectively, and the remaining one is fixed to the third shaft meshing with the second pair of gears. Except link gears one or two gears, at least, must be partially toothed gears having teeth in sector. The shaft having this partially toothed gear rotates drivingly in a certain direction meshing with other gear and transmits the gear action intermittently. Through link gears these intermittent actions are combined in an oscillatory motion.
  • crank and connecting link mechanism The most wide using mechanism to transform rotary motion into oscillatory motion at present is the crank and connecting link mechanism.
  • this normal simple crank and link mechanism has several defects. By this mechanism, it is almost impossible to get more than 90 degrees of oscillation, even not allowing to set the shaft supporting devices on both sides and giving unequal half cycle time. But it can not be neglected that the latter fuction is contributing to us as "quick return mechanism" in many kinds of machineries.
  • the objection of this invention is to settle the above mentioned defects and to provide a wider angular movement such as 180° including an intermittent oscillatory motion and also, in case of requiring, two opposite oscillating movement at same time.
  • Fig. 1 and 2 are a schematic front view and a side view showing a shaft having a partially toothed gear rotates, the other two shafts having a large gear and a smaller gear on each oscillate in opposite directions.
  • Fig. 3 and 4 are the same view as Fig. 1 and 2 except the cross sections of the three shafts are not lined in a row.
  • Fig. 5 and 6 are a schematic front view and a side view showing two shafts having a partially toothed gear and an ordinary gear on each rotate in opposite directions, the third shaft having a gear oscillates.
  • Fig. 7 is showing a set of plate cam.
  • Fig. 8 is a schematic fragmental view showing the action starting point.
  • Fig. 9 is showing a different action starting point to Fig. 8.
  • Fig. 10 is a schematic fragmental view showing one of the stub tooth on the driven gear.
  • Fig. 11 is showing one of the skewed stub tooth on the driven gear.
  • a 1 is a rotating input shaft and b 1 , b 2 are the oscillating shafts paralleled to a 1 .
  • A is a partially toothed gear having teeth in sector and is fixed to shaft a 1
  • a pair of gears B 1 and B 2 is fixed to shaft b 1 and D 2 , respectively, meshing with the gear A in turn when it rotates to R direction.
  • Another pair of big gears C 1 and C 2 meshing with each other is fixed to the shaft b 1 and b 2 , too.
  • Z A the total number of teeth (or the number of circular pitches) could be made on the gear A and Z B that of the gear B 1 or B 2 .
  • ⁇ is the number of remained teeth on gear A and ⁇ is the ⁇ egrees of the center angle both indicating the number of teeth (or the number of circular pitches) in the intercepting range between to the addendum circles of the gear A and B.
  • the oscillating angle ⁇ is also indicated by in the number of teeth or the number of circular pitches.
  • the two parallel shafts a 1 and a 2 having a pair of meshing gear C 1 and C 2 , as link gear, on each shaft and rotate in the opposite directions.
  • a pair of partially toothed gear A 1 and A 2 which size is equal or smaller to that of the link gears, is fixed.
  • the arrangement of gear A 2 is, after rotating A 1 gear to 180° around the shaft a 1 symmetrizing to the line vertical to a 1 - a 2 line and passing through to the center of the shaft b 1 .
  • the oscillating gear B is fixed to this shaft b 1 which is parallel to the rotating shafts a 1 and a 2 , meshing with the two gears A 1 and A 2 in turn.
  • the cross sections of the three shafts form a triangle. First the teeth on gear A 1 meshes with the teeth on gear B, turning it to Lo direction and then the teeth on A 2 meshes with the teeth on gear B, turning it to Ro direction.
  • ⁇ x is the maximum number of the remained tooth on the rotary input gears A 1 and A 2 , and can be obtained from the same equation, as said,
  • the action starting point would be either S 1 in Fig. 8 and S 2 in Fig. 9 or a point between these two points.
  • This invention is good to apply for the relatively low speed and light load because of the impact which arises at the action starting moment. It is also desired to reduce the stand still moment of inertia by using springs, cams and etc. To avoid the weakness of the first tooth on the gears, it is also suggested to rotate the input gear, which has the Geneva Stop cam, in the reverse direction.
  • this invention can easily be tried to apply to the wide range wiper brushes on automobiles, to the traditional wind fans oscillated by electric power, to the toys required various oscillatory motions and etc.

Abstract

Dispositif permettant d'obtenir un mouvement oscillatoire à rendement élevé avec un grand angle d'oscillation, une vitesse relativement faible et une petite charge en utilisant trois arbres et cinq engrenages droits. Une paire d'engrenages ordinaires fixés sur deux arbres sont en prise l'un sur l'autre en tant qu'engrenages de liaison, tandis qu'une autre paire d'engrenages fixés sur les mêmes arbres, respectivement, sont en prise avec l'engrenage restant sur le troisième arbre des deux côtés. A l'exception des engrenages de liaison, au moins un ou deux engrenages doivent être partiellement dentés présentant des dentures divisées en secteurs. Lors de la rotation d'un arbre ne possédant qu'un engrenage partiellement denté, la paire d'arbres restants oscille. Lorsqu'une paire d'arbres possédant une paire d'engrenages partiellement dentés tournent dans des directions opposées, le troisième arbre ne possédant qu'un engrenage oscille. Pour garantir un mouvement fiable et sans à-coups, il est nécessaire d'utiliser un ensemble de cames faisant office d'un mécanisme d'arrêt par mouvement de Genève.
