Title
(EN) SPROCKET WITH HYDRODYNAMIC BEARING
(FR) ROUE DENTEE AVEC SUPPORT HYDRODYNAMIQUE
Abstract
(EN) A nose sprocket for a chain saw guide bar, where the bottom part of the teeth or the outermost part of the central region or both have indentations with softly inclined trailing edges, acting as hydrodynamical bearings to keep the sprocket centered between the side plates of the guide bar.
(FR) L'invention concerne une roue dentée destinée au nez d'une glissière de guidage d'une scie à chaîne. La partie inférieure de chaque dent, la partie extérieure de la zone centrale ou les deux sontdotées d'entailles aux bords arrière légèrement inclinés, ces entailles servent de support hydrodynamique pour garder la roue bien centrée entre la plaque latérale de la glissière de guidage.
