Abstract

A mechanism to set in motion the rectilinear transfer of a moving body sliding in relation to a support is disclosed. A servomotor drives a shaft in rotation. The rotation is transformed by pulleys and belts. Two belts are staggered along the shaft axis and are wound on two pulleys of the same diameter. A first end of each of these belts is attached to the corresponding pulley, while the second end of each of these belts is attached to the moving body, the winding directions being opposite so that each rotation in one direction or the other of the shaft causes the winding of one of the belts and the unwinding of the other. Application is to Cartesian displacement robot arms and devices of rectilinear transfer with cross-motions back and forth and up and down.
