The body (1) containing a material to be treated and moving about two non-intersecting axes (39, 40) and having different directions owing to a Cardan suspension (35 to 40). The body (1) effects a transfer and oscillation motion due to the rotation in opposite directions of two parallels shafts (21, 22) engaging each the Cardan suspension. Each shaft (21, 22) comprises a pair of discs (26, 27) intended to compensate for the variation of the rotation torque, of which the driving disc (26) may rotate freely with respect to the shaft and is connected to a driving wheel, whereas the driven disc (27) is integral with the shaft. An annular channel (262, 272) provided between the two discs (26, 27) encloses energy accumulators in the form of helical compression springs (53) alternating with balls (52), which bear onto two stops, one being integral with one disc and the other one with the other disc. When the disc (26, 27) rotate one relative to the other, the springs (53) accumulate energy which will then be released. |
