Hydraulic telemotor reversing drive

摘要

The invention relates to a hydraulic telemotor reversing drive, the primary-side hydraulic generator of which can be driven by a stroke mechanism and the secondary-side hydraulic motor of which is designed as a piston/cylinder unit and is connected to a rectilinearly reversible tool carrier. The aim of the invention is stroke-length adjustment of the tool carrier without machine stoppage and manual work, favourable loading conditions of the crank drive and dynamic stroke-length adaptation. According to the object the stroke-length change is realised at constant crank radius of a stroke mechanism (mounted on multiple supports) in such a way that it can be integrated in an infinitely adjustable manner for automated working sequence. According to the invention, the primary-side hydraulic generator is formed from at least two piston/cylinder units, the cylinders of which are connected to one another in such a way as to act in the same direction, and the primary-side piston/cylinder units are infinitely adjustable in the phase position of their movement by means of a phase-displacement device. An electronic positive-control means or a differential mechanism is provided as the phase-displacement device. <IMAGE>
