LARGE AMPLITUDE LINEAR DISPLACEMENT DEVICE PRODUCED BY A CREW OF MECHANICAL MODULES COMBINABLE TO WILL AND MUS BY A SAME ROTARY ENERGY SOURCE.

摘要

The invention relates to the field of mechanics and more particularly to large amplitude displacement and load immobilization devices. The invention achieves the objective by a plurality of identical and elongate members (3), forming a crew (4), moving simultaneously relative to each other, according to their longitudinal axes parallel to each other (5), of the same fraction (6) of this amplitude, being all slaved to each other and by any one of them to a same rotary energy source (7) by an identical power transmission device for each of the members of the crew, designed to connect them to each other without a solution of continuity, including in particular a threaded shaft (8) carrying at least one keyway (9) over the entire length of its thread, and this shaft drives a first gear, said fixed (14) and a second toothed wheel, (17) whose key allows it to slide in the groove (9) of the shaft (8), driven by the captive nut (26) complementary to the threaded shaft , and the device also includes at least one third gear wheel (29), said free, also slaved to the nut (26), capable of binding the rotations of the toothed wheel (14) of the shaft (8) of a member (3) and the wheel sliding tooth (17) of the shaft (8n) of the next member (3n). A rigid connection of the nut (26) and the member (3n) causes the longitudinal displacement of the latter. Application to the realization of moving floors and walls and all types of mobile suspension bridges.
