Abstract: There is proposed a converter, comprising a body set up in a trunnion ring with trunnions on which multimotor drives are mounted with the gear hub of a low-speed reducer, with at least one trunnion being provided on the side of the multimotor drive with a bush and with said gear hub having a socket adapted to be joined with said bush, whose external surface is adjusted to fit in shape and size the corresponding surface of the socket, through which the trunnion is coupled with the gear hub of the low-speed reducer by means of a flexible joint.
