Definitions

  • the invention relates to an infinite speed transmission.
  • Multiple speed transmissions are well known in on road and off road vehicles and industrial applications.
  • the two main types of transmission are the lay shaft with a synchronizing unit for ratio changing and the automatic using epicyclic gearing and mu!tipiate clutches. Both require a high number of parts.
  • the infinite speed transmission shown has a small number of parts and only two gears for changing speed.
  • an infinite speed transmission as defined in the claim.
  • the invention includes an input shaft driving a gear in turn driving a cone gear connected to an output shaft.
  • the cone having multiple spiral gear teeth along its outer surface.
  • the angle of the spiral gearing is determined by the cone ratio of small diameter to the large diameter and also the cone length. Reducing the cone length will increase the teeth contact angle. Increasing the cone length reduces the teeth contact angle.
  • the transmission has an input shaft 1 driving one or more gears 2 attached to a splined shaft 3 rotating parallel to the outside of the cone gear 4 a gear S able to slide axially on splined shaft 3 mating with cone gear 4 attached to the output shaft 6.

Abstract

Dans la présente invention, un appareil moteur entraîne un arbre d'entrée entraînant à son tour un arbre cannelé tournant parallèle à l'extérieur d'un engrenage conique. L'arbre cannelé comporte un engrenage pouvant coulisser en sens axial en prise avec le cône fixé à l'arbre de sortie, augmentant ou diminuant sa vitesse sans aucune interruption de puissance.
