Abstract

1,141,217. Drilling machine. DONETSKY NAUCHNO-ISSLEDOVATELSKY UGOLNY INSTITUT. 5 July, 1967, No. 30947/67. Heading B3C. [Also in Division H2] A mining drill comprises a tool 6, Fig. 1, connected to a screw 2 at 7, the screw being driven by the rotor 5 of an electric motor, through gears 3 and clutch 4, and a nut 8 driven at a slower speed by a rotor 9, rotatably mounted on the shaft of rotor 5, through gearing 10. In operation, with rotors 5, 9, in series, the nut and screw are rotated at different speeds, tool 6 rotates and is fed up to the work. When the tool abuts the work, an axial force is transmitted to the nut by the screw, and the nut is accelerated, owing to friction between the members. Rotor 9 is now driven by the nut, and the power generated is passed through the magnetic flux of the stator, to thus increase the efficiency of rotor 5. In a modification, rotor 9, Fig. 3, drives screw 2 through gearing 15, and rotor 5 drives tool 6, and also nut 8, through gearing 16 and dog clutch 17.
