Abstract

Organes de transmission. Le dispositif comporte : une première courroie 5 passant sur une poulie motrice 6 solidaire de l'arbre moteur 1 et sur une première poulie intermédiaire 7 portée par un support mobile 9; une deuxième courroie sans fin 12 passant sur une poulie de marche avant 13 solidaire de l'arbre récepteur 2 et sur une deuxième poulie intermédiaire 14 solidaire de l'une des deux poulies sur lesquelles passe la première courroie 5; une poulie de marche arriere 27 solidaire de l'arbre récepteur 2 et contre laquelle peut être pressé le dos de la première courroie 5 pour une position correspondante du support mobile 9; et des moyens 7 de tension de la première courroie 5 ainsi que des moyens 16 de tension de la deuxième courroie 12. Applicable à l'accouplement débrayable de deux arbres, avec ou sans inversion de leurs sens respectifs de rotation.Transmission organs. The device comprises: a first belt 5 passing over a driving pulley 6 integral with the driving shaft 1 and over a first intermediate pulley 7 carried by a movable support 9; a second endless belt 12 passing over a forward pulley 13 integral with the receiver shaft 2 and over a second intermediate pulley 14 integral with one of the two pulleys over which the first belt 5 passes; a reverse pulley 27 integral with the receiver shaft 2 and against which can be pressed the back of the first belt 5 for a corresponding position of the movable support 9; and means 7 for tensioning the first belt 5 as well as means 16 for tensioning the second belt 12. Applicable to the disengageable coupling of two shafts, with or without inversion of their respective directions of rotation.
