Abstract

L'invention concerne le domaine minier, et notamment les entraînements d'organes terminaux d'une haveuse destinée à l'extraction de minerais. L'invention concerne des moyens de protection des éléments de transmission d'un organe terminal d'une haveuse. Un élément de cisaillement est monté dans un bloc de sécurité supplémentaire et est constitué de deux demi-manchons cannelés connectés entre eux coaxialement de manière à pouvoir tourner l'un par rapport à l'autre et entrer en contact avec les éléments du schéma cinématique du réducteur ainsi que l'élément de cisaillement. Les demi-manchons cannelés sont reliés par leurs orifices axiaux à l'élément de cisaillement de sécurité de manière à pouvoir transférer le couple, et sont munis à leurs extrémités de couvercles portant des éléments pour l'extraction du bloc de sécurité. Le résultat technique consiste en la séparation dans le schéma cinématique de l'entraînement de l'organe terminal de la haveuse des fonctions d'amortissement (suppression) de l'amplitude des oscillations de torsion et la sécurisation de la transmission contre les charges admissibles maximales.
