Definitions

  • the present invention relates to a torque multiplying device which operates by utilizing centrifugal forces .
  • the object of the present invention is to utilize the centrifugal force of rotating masses to create and increase an output torque of a shaft of the device .
  • - Figure 1 is a cross sectional view of the torque multiplying device
  • - Figure 2 is a longitudinal sectional view of the device as taken along line I-I of Figure 1;
  • FIG. 3 and 4 schematically show the operation of the device in two operating conditions .
  • numerals 1 and 2 designate two plates which form, with an annular band 3 , the case 4 of the device .
  • a hub 5 is attached to the plate 1 and supports , through two bearings 6 and 7 , a driven shaft 8 which is connected by means of a free wheel 9 to an electric motor 10 flanged to said hub 5.
  • a first disk 11 is mounted to the driven shaft 8, and has five slots 12 arranged radially and equally angularly spaced relative to the axis of the driven shaft 8 .
  • Each of said slots has a roller 13, mounted on a pin 14, freely sliding therein, which is supported by a swinging mass 15 pivoting about a pin 16 supported by two flanges 16a and 16b which are integral with an output shaft 22 fastened to a second disk 17 by the screws 18.
  • the second disk 17 is fastened by screws 18 to the flange 16a.
  • the plate 2 has a hub 19 attached thereto, which is offset with respect to the hub 5 and is adapted to support, through bearings 20 and 21, an output shaft 22 which is in turn offset by A with respect to the driven shaft 8.
  • the second disk 17 is mounted to the drive shaft 22.
  • Numerals 23 and 24 designate the two axes of rotation of the output and driven shafts respectively, which are at a distance A from each other.
  • Five swinging masses 15 are provided, which are hinged at 16 to a second disk 17 whose axis of rotation is offset with respect to the axis of rotation of the first disk 8.
  • the disk 17 acts as a phase shifting member between the driving and driven shafts , as it has five holes 25, a roller 26 carried by a pin 27 attached to the disk 11 being free to slide along the wall of each hole.
  • the holes 25 shall be at least three in number, arranged at 120° from each other, but the greater their number the smoother is phase shifting with no rattling.
  • the phase shifting member for the two shafts may- consist, in a possible variant embodiment, of a chain 40 which meshes with pinions 41 and 42 mounted to the driven shaft and the output shaft respectively.

  • Each mass 30 has a slot 33 within which a roller 34 supported by the pin 14 can slide.
  • the centrifugal forces of the five swinging masses are radially oriented and pass through their respective centers of gravity thereby creating a torque which depends on the distance of the swinging masses from the center of rotation of the swinging masses, said distance or length being designated as B .
  • the total torque will be the summation of the five centrifugal forces for the respective lengths .

Abstract

L'invention concerne un dispositif de multiplication de couple ayant un premier disque (11) amené à tourner par un arbre entraîné qui est entraîné en rotation par un moteur électrique. Des fentes (12) sont disposées sur le premier disque, pour qu'une broche (13) coulisse à l'intérieur de celles-ci, cette broche étant portée par un bras oscillant (15) articulé sur un deuxième disque (17) monté sur un arbre de sortie (22). L'axe des fentes est décalé de façon angulaire par rapport à la position du centre de rotation du bras oscillant, de telle sorte que les forces centrifuges produites par les bras oscillants tournants créent des couples dépendant de la distance du centre de rotation des bras par rapport au centre de gravité des bras. Un élément de décalage de phase est prévu pour régler la position angulaire relative des deux arbres.
