Device for cooling and stabilizing the cured tyre

A device for cooling and stabilizing a cured tyre, comprising:

• a beam that comprises at least one non-movable element;
• at least one movable element;
• at least one guide to enable movement of the movable element along the beam;
• at least one actuator arranged to move the movable element relative to the beam;
• wherein one of the non-movable element and the movable element comprises a shaft having at its end at least one spline, and a first disc in the axis of which the shaft is positioned;
• and the other of the non-movable element and the movable element comprises a closing mechanism comprising:
• a second disc with a threaded axial opening,
• a main electric motor;
• and
• a securing socket having a cylindrical shape with a thread at least at a portion of the height;
• wherein the closing mechanism is configured to cooperate with the shaft by means of the securing socket corresponding to the shape of the at least one spline and to adjust the size of the tyre through sliding, along the axis, of the second disc, and the main electric motor is coupled with the securing socket so that it enables rotation of the securing socket, and on the securing socket, on the threaded portion, the second disc is mounted so that rotation of the securing socket causes sliding of the second disc along the axis of the securing socket;
• and the closing mechanism is configured to enable adjustment of the second disc in parallel to the axis of the beam,
• wherein an overstroke limitation unit is mounted to the non-movable element and comprises an additional electric motor and a pinion, a toothed wheel is secured to the first disc at the side of the non-movable element, and positioned on the axis of the first disc and in the axis of the shaft, to cooperate with the pinion, the shaft has a thread on the outer surface of at least a portion of the height of the shaft,
• and the additional electric motor is coupled with the pinion so that the overstroke limitation unit is configured to adjust the distance to the first disc, and the pinion is coupled with the toothed wheel so that the rotation movement of the pinion causes a plane motion of the first disc in parallel to the axis of the beam.
