Study of the possibility of using the electric motor of the main movement of the machine with a reduced number of steps of the gearbox and frequency converter

Modern methods of modernization of the drives of the main movement of lathes are considered. The optimization of the operation of the FT-11 screw-cutting lathe was carried out by simplifying the kinematic chain of the main movement drive and introducing frequency-controlled speed control. The optimization takes into account the capabilities of the motor bearings as well as the converter. In the mathematical environment MatLab & Simulink, a block diagram was built to calculate the critical moment brought to the spindle, as well as diagrams for constructing the mechanical characteristics required and those that can be provided on the machine spindle after simplifying its kinematic chain. An algorithm for reducing the number of gear box stages of the main drive is developed and presented.
