Definitions

  • the present system refers to an improved system for torque transmission between two axles whose centerlines can be inclined with respect to each other, incorporating special features which permit high torque transmission capa ⁇ city and constant angular velocity of the two axles.
  • the system uses a bell-shaped outer member fixed to one of the axles and a ball-shaped inner member fixed to the other axle.
  • Six uniformly distributed steel balls, wor ⁇ king within special shaped ball races in the outer and in ⁇ ner transmission members, are used to transfer the torque from the driving axle to the driven axle.
  • a ball cage is mounted between the outer and inner transmiis sion members in such a way that the plane formed by the cen- ters of the six balls always divides the angle formed by the axles in two equal parts.
  • Figure B represents the theoretical arrangement of one of the six balls, shown on an enlarged scale.
  • the arrows PI are representing the forces acting between the inner transmission member (2) and the balls; the arrows P2,the cor responding forces acting between the balls and the outer transmission member (1).
  • Figure B also shows that the lenght of the circular arcs, represented with heavy lines, are par- ticipating in transmitting those forces, due to the fact that in this theoretical arrangement the radius of the ball and the ball races of inner and. outer transmission members are exactly the same.
  • This invention presents a new and improved design for the form of the ball races, solving at the same time the problems due to elastic deformation and also the friction problem caused by the elevated speed and direction differen ⁇ ces and eliminating the reduction of transmitting capacity due to the point contact between balls and elliptical races.
  • the radius of the balls equal to (r).
  • the ball races of the outer member (1) and the in ⁇ ner one (2) are also formed as arcs of a circle with the cor responding lenght (tl) and (t2) and with the radius (r) exac tly the same as the radius of the balls, but their centers are displaced to the right and to the left of the center of the ball to a distance (S) .
  • the balls are in perfect contact with the ball ra ⁇ ces of the outer and the inner transmission member within the lenght (b) , making this contact along the lines of cir ⁇ cular arcs instead of points, as it is in the case with el- liptical races.

Abstract

Un système amélioré permet de transmettre des couples très élevés à une vitesse constante angulaire entre les deux axes et sans entraîner des usures, quelles qu'elles soient, des éléments de transmission de puissance. A cet effet, on utilise un contact linéaire le long des arcs des cercles au lieu du contact ponctuel d'usage dans des chemins elliptiques de roulements à billes. Ce système à arcs circulaires de contact entre les billes et leur chemin de roulement comprend l'utilisation de deux centres séparés pour les deux arcs circulaires à chaque chemin de roulement interne et externe. Les bords largement ouverts des chemins de roulement empêchent tout blocage de la cage du roulement à billes dû à des déformations élastiques des composants transmetteurs de puissance du système.
