Abstract

La présente invention est relative à un dispositif d'accouplement comportant une sécurité. Elle concerne en particulier un accouplement de sécurité pour deux organes tournant autour d'un même axe, ces deux organes étant reliés l'un à l'autre par une goupille à cisaillement, caractérisée par le fait que ladite goupille est portée par l'un desdits organes et attelée à des moyens provoquant son déplacement, par rapport à celui-ci de façon à ce qu'elle vienne s'engager sur l'autre organe, de telle sorte que, en fonctionnement normal, les deux organes soient liés en rotation, que la rupture de la goupille les désolidarise l'un de l'autre et que le déplacement de la goupille, après rupture les resolidarise à nouveau.The present invention relates to a coupling device comprising a safety. It relates in particular to a safety coupling for two members rotating around the same axis, these two members being connected to each other by a shear pin, characterized in that said pin is carried by one said members and coupled to means causing its displacement, relative to the latter so that it comes to engage with the other member, so that, in normal operation, the two members are linked in rotation , that the breakage of the pin separates them from one another and that the displacement of the pin, after breaking, resets them again.
