Industrial gearboxes are mechanical drives designed to reduce rotational speed and increase torque from an electric motor to an actuator. Cylindrical single- and double-stage gearboxes (Ц2У, 1Ц2У) — efficiency 96–98%, for conveyors, mixers, elevators. Worm gearboxes (Ч, 2Ч) — compact, self-locking, gear ratio up to 80, for conveyors, valves, mixers. Bevel gearboxes (К, КЦ) — for changing the axis of rotation by 90°. Planetary gearboxes — for high torque in a compact housing (robots, extruders). Torque range: 100–500,000 N·m. Compliant with GOST 20758-75 "General-purpose gearboxes".
