<p>Disclosed is a reduction device (51) for transmitting motion to a crusher, with a first and a second driven shaft (53, 55) parallel with each other and which can be coupled to crushing tools (U1, U2) of the crusher. The device comprises an arrangement of reduction stages (67; 79; 89) in series with one another, between a coupling interface (69A, 69B) with one or more motors (MA; MB; MC; MD) and the driven shafts of the device. The output of the last stage of the series of reduction stages is coupled to a first driven shaft, to transmit thereto the necessary torque supplied by the motor or motors interfaced with the input of the first reduction stage. The second driven shaft receives torque through a transmission (101, 103) from the output of the last reduction stage. <IMAGE></p> |
