Beschreibung
Zusammenfassung:	coal mining machines used in coal industry. SUBSTANCE: device has an electric motor, feed mechanism, reducing gear of actuating member drive. As distinguished from known devices for regulation of shearer load, claimed device is additionally provided with hydraulic system which consists of pump, regulated hydraulic motor and automatic regulator, and drive reducing gear of actuating member has a planetary mechanism including carrier, ring and sun gears. Carrier is connected to the electric motor, ring gear is output and pump is connected to sun gears. Hydraulic motor is made with positive feedback and connected to the electric motor shaft. Automatic regulator is connected to hydraulic pump of feed mechanism. EFFECT: increased productivity of shearer, improved granulometric composition of mined coal and reduced power consumption. 1 dwg
