Abstract

Une lisse d'usure rectangulaire et auto aiguisante pour un ski de motoneige: elle comprend une lame centrale rectangulaire encastrée au milieu d'un support aussi rectangulaire et mince. La dureté du support est inférieure à celle de la lame centrale au carbure, qui peut glisser sur une surface dure comme celle d'un chemin asphalté, alors qu'elle peut creuser un sillon profond pour procurer de la conduite, de l'adhérence pour tourner sur la glace et pour protéger le support contre l'usure lors du glissement sur des chemins asphaltés ou sur des chemins de gravier gelé ou abrasif. Le support s'use lors du passage sur les chemins de gravier gelé et entremêlés à la neige mais après qu'il a une certaine protection par le carbure. Il y a toujours une différence d'usure par rapport à la différence de dureté et de hauteur entre la lame et le support, sur toute la profondeur de la lisse d'usure, la rendant ainsi auto aiguisante jusqu'à l'usure complète du carbure (30).A rectangular, self-sharpening wear strip for a snowmobile ski: it includes a rectangular central blade embedded in the middle of such a rectangular and thin support. The hardness of the carrier is less than that of the central carbide blade, which can slide on a hard surface such as that of an asphalt road, while it can carve a deep groove to provide ride, grip for turn on ice and to protect the substrate from wear when sliding on asphalt roads or on frozen or abrasive gravel roads. The backing wears out when going over frozen gravel paths and interspersed with snow but after that it has some protection by the carbide. There is always a difference in wear compared to the difference in hardness and height between the blade and the support, over the entire depth of the wear bar, thus making it self-sharpening until the wearer is completely worn out. carbide (30).
