A non-circular sprocket component comprises a rotor (11) having a plurality of teeth (16) arranged around the perimeter of the rotor, each tooth having a crown (9), and each pair of adjacent teeth having a valley (8) therebetween. The crowns of the teeth lie on a curved envelope forming the perimeter of the rotor. The perimeter has a non-circular profile having at least two protruding portions (22, 23) alternating with receding portions (24, 25). The distance between the midpoints (V) of the crowns (9) of each pair of adjacent teeth is substantially the same. The profile of the valley (8) between each pair of adjacent teeth is substantially the same. The distance between the midpoint (V) , of each crown (9) and the axis (A) of the rotor varies around the perimeter to produce the said non-circular profile.
L'invention concerne un constituant de roue dentée non circulaire, qui comprend un rotor (11) possédant plusieurs dents (16) placées autour du périmètre du rotor, chaque dent possédant une couronne (9), et chaque paire de dents adjacentes étant séparées par un creux (8) situé entre les deux. Les couronnes des dents se situent sur une enveloppe incurvée formant le périmètre du rotor. Ce périmètre possède un profil non circulaire avec au moins deux parties en saillie (22, 23) en alternance avec des parties en retrait (24, 25). La distance entre les points médians (V) des couronnes (9) de chaque paire de dents adjacentes est sensiblement la même. Le profil du creux (8) situé entre chaque paire de dents adjacentes est sensiblement le même. La distance entre le point médian (V) de chaque couronne (9) et l'axe (A) du rotor varie autour du périmètre pour former le profil non circulaire.
