Abstract
Inventia se refera la un echipament electrohidraulic utilizat la actionarea unitatilor de translatie sau rotatie cu precizie de pozitionare ridicata, cum ar fi robotii industriali, masinile-unelte, sistemele de directie etc. Echipamentul electrohidraulic, conform inventiei, realizeaza o miscare de rotatie într-un sens sau altul a motorului electric pas cu pas este transformata într-o miscare de translatie, în sensuri corespunzatoare ale sertarului prin intermediul unui cuplaj cu silfon care permite deplasarea axiala a surubului de comanda datorita însurubarii lui într-o piulita de reactie prevazuta cu un ax la care exista un moment rezistent creat de sarcina unui motor hidraulic, piulita de reactie rotindu-se într-un capac prin intermediulunor rulmenti, reglarea debitului de fluid fiind functie de o sectiune de deschidere dintre sertar si bucsa, sectiune rezultata datorita defazajului dintre miscarea de deschidere transmisa sertarului de motorul electric pas cu pas si miscarea de închidere transmisa sertarului prin arborele piulitei de reactie din motorul hidraulic.The invention relates to electrohydraulic equipment used to drive translation or rotation units with high positioning accuracy, such as industrial robots, machine tools, steering systems, and the like. The electrohydraulic equipment according to the invention makes a rotational movement in one way or the other of the electric motor step by step is transformed into a translational movement in corresponding directions of the drawer by means of a sleeve coupling which allows axial displacement of the screw the control due to its screwing into a reaction nut provided with an axle at which there is a torque created by the load of a hydraulic motor, the reaction nut being rotated in a cap by means of bearings, the adjustment of the fluid flow being a function of a section opening between the drawer and the bush, resulting section due to the phase shift between the opening movement transmitted to the drawer by the stepper electric motor and the shutter movement transmitted to the drawer via the hydraulic drive shaft spindle shaft.
