DRIVE OF ACTUATOR OF EXCAVATION MACHINE (OPTION) Russian patent published in 1996 - IPC

FIELD: mining. SUBSTANCE: drive of actuator of excavation machine has electric motor, reduction gear box, gear box off mechanism with toothed coupling on power shaft and off shaft kinematically linked to the coupling secured to the case parallel to power shaft axis. A roller engaging toothed sleeve of the coupling through slots and ledges made on their lateral surfaces is put to off shaft end, and may be revolved. Coupling toothed sleeve is connected to power shaft through spline connection and may be moved in axial direction about toothed holder secured to one end of reduction gear toothed wheels. The reduction gear is installed on power shaft and may be revolved. As for another option, kinematic link between the sleeve and off shaft is carried out through additional sleeve and screw-nut coupling installed inside off mechanism sleeve.
