Patent

CA 2342197

Rope-holding characteristics of a winch drum (2) are determined by a staggered array of pyramidal protuberances (12, 14, 17, 19) on its surface. The staggering is such that there is no true circular path round the drum within the array, and a rope wound on it in the hoop direction is deflected sinusoidally.

Les caractéristiques de maintien du cordage, d'un tambour de treuil (2) sont déterminées par un groupe superposé de protubérances pyramidales (12, 14, 17, 19) sur sa surface. La superposition est conçue de manière qu'il n'y ait pas de chemin circulaire véritable autour du tambour, dans ledit groupe de protubérances, et qu'une corde enroulée autour de ce dernier dans le sens de rotation du tambour soit défléchie de manière sinusoïdale.
