timing belt and timing belt transmission

摘要

the invention relates to a belt.the teeth have a certain height of the head h and the hips are incurvati form convex in cross section of the profile. it is alsoa transmission belt, formed from straps of this kind and sprockets.the invention proposes to aim to extend the useful life of the belt, with reference to broadcast to belt type fast, at least not worse in this regard.the noise level.to this end, it is proposed according to the invention, the hips of the belts are incurvati convex in shape.at least in the radial field between 25% and 80% of the height (h) of the head of the teeth in such a way that all the centers of curvature of the area of the side of the belt itself isradially outside the line primitive.
