Abstract

L'invention concerne les chaînes dans lesquelles les godets sont montés par deux anneaux ou oreilles solidaires du godet et mutuellement alignés sur chacun des deux côtés opposés du godet. Selon l'invention, le joint formé sur chaque anneau 1 présente des surfaces de portée non pas cylindriques, mais sphériques, sur les coussinets 10, 11. Cette conformation réduit l'usure et le bruit des joints et augmente la durée de service.The invention relates to chains in which the buckets are mounted by two rings or lugs integral with the bucket and mutually aligned on each of the two opposite sides of the bucket. According to the invention, the seal formed on each ring 1 has bearing surfaces that are not cylindrical, but spherical, on the bearings 10, 11. This configuration reduces wear and noise on the seals and increases the service life.
