CA 2729836

An article for use in a torque transmitting system which has a drive surface configuration having side and end surfaces is disclosed. The end surface tapers upwardly and outwardly from a lowermost point provided along a longitudinal axis to the side surface. The end surface defines a plurality of identically configured lobes that extend from a first point to a second point. The first point of one lobe is identical to the second point of an adjacent Jobe. The first and second points of each lobe are provided along an imaginary circle having its center along the longitudinal axis. Each lobe extends from the first point to the second point by a series of edges that are straight, concave and/or convex. Two of the edges are tangential to the imaginary circle. The side surface extends upwardly from the edges defining the plurality of lobes.

La présente invention concerne un article destiné à être utilisé dans un système de transmission de couple qui comporte une configuration de surface dentraînement qui possède des surfaces latérale et dextrémité. La surface dextrémité seffile vers le haut et vers lextérieur à partir dun point le plus bas prévu le long dun axe longitudinal jusquà la surface latérale. La surface dextrémité définit une pluralité de lobes configurés de façon identique qui sétendent dun premier point à un second point. Le premier point dun lobe est identique au second point dun lobe adjacent. Les premier et second points de chaque lobe sont prévus le long dun cercle imaginaire dont le centre se trouve le long de laxe longitudinal. Chaque lobe sétend du premier point au second point selon une série de bords qui sont droits, concaves et/ou convexes. Deux des bords sont tangentiels par rapport au cercle imaginaire. La surface latérale sétend vers le haut à partir des bords qui définissent la pluralité de lobes.
