Abstract

Les chaînes d'entraînement du rabot et de la bande du transporteur à raclettes sont soulagées des efforts d'allongement qui leur sont imposés dans l'art antérieur. Le guide du rabot est constitué de segments de guidage, et le couloir est constitué de tronçons. A chaque tronçon 4 correspond un triplet de segments 6, 7, 8. Les surfaces d'aboutement 12 des segments extrêmes 6, 8 de chaque triplet déterminent des taquets 11 saillant au-delà des extrémités des tronçons entre lesquelles ils maintiennent un débattement S, de sorte que les réactions des moyens de traction ne sont supportées que par les segments. Application au matériel minier, notamment pour charbonnage.
