Switch operating mechanism for railway infrastructure, has ball screw maintained in translation along directions by bearings interdependent of stages and transmitting energy multiplied in translatory movement along directions with trolley

摘要

The mechanism has an electrical motor (8) and a mechanical assembly actuated with two exit arms (9, 10) that are connected with a needle and a manual device. The electrical motor in rotation is installed on a frame (1) through a safety clutch. A reducing pinion from a set of reducing pinions (6a-6c) is interdependent of a ball screw. The screw is maintained in translation along two directions by two oblique contact bearings interdependent of stages (1b). The screw in rotation transmits an energy multiplied in a translatory movement along directions with a trolley through a ball nut (4b).
