“…Designed to impart torque to the working body when drilling vertical and inclined wells in hard rocks (up to 20 on the scale of Prof. M.M. Protodyakonov) with a roller bit to a depth of up to 40 m in open-pit mining of ferrous and non-ferrous metallurgy, as well as in mining and chemical quarries industry and enterprises of the building materials industry, over the entire operating speed range of the DC drive electric motor DPV-52 (Figure 2) [5,6,11,[18][19][20]. The developed new design of the rotary-feeding mechanism, the kinematic and hydraulic diagram of the machine (Figure 2) gives it the properties of a hydraulic drive and allows you to significantly change the dynamic characteristics of the entire drilling rig during setup and operation, as well as gain new advantages over the traditional hydraulic drive, namely:…”

This article substantiates and describes the design and operating principle of an electrohydromechanical rotator, presents the results of experimental studies of a prototype, shows ways to reduce dynamic loads and recommendations for improving the rotary-feeding mechanism of a drilling rig of the SBSh-250MNA-32 type. An improved kinematic and hydraulic diagram of an electrohydromechanical rotary-feeding mechanism and installation of a feed pump with a drive electric motor in the machine room of a drilling rig are presented. A design has also been developed for the electrohydromechanical rotary-feeding mechanism of the drilling rig, which can significantly reduce transmission vibrations, increase durability, and, as a result, the productivity of the machine.
