Electromechanical Actuator with a Planetary Roller-Screw Mechanism for the Electrochemical Machine with an Oscillating Tool Electrode

This article deals with the questions of modernization of the electromechanical drive of translational movement with a planetary roller screw actuator developed for the previously implemented design of the electrochemical machine EKhS–5000. The machine was designed for manufacturing thin-walled spatial aerodynamic blade profiles of gas turbine engines. The purpose of the modernization was to increase the accuracy of shaping and the quality of processing complex high-strength surfaces of turbine blades by creating vibration of the tool electrode in the direction of the main feed that forms the interelectrode gap. Based on the calculation of the required amplitude and vibration frequency of the tool electrode, a comparative analysis was performed to evaluate the capabilities of the linear electric motor and two variants of the electromechanical drive of translational motion with a planetary roller screw actuator based on the stepping or the synchronous motor. It is shown that the electromechanical actuator based on the synchronous electric motor FXM14 and the planetary roller-screw mechanism 52.8х1х60 with long threaded rollers with the coaxial arrangement of the drive and a cylindrical guide of the working head satisfies the requirements to the machine EKhS-5000 the most. According to the calculation results, such electromechanical drives can guarantee vibration of the tool electrode with the required frequency from 50 Hz to 10 Hz and the corresponding range of oscillations from 0.016 mm to 0.380 mm.
