Industrial gear reducers are mechanical transmissions used to decrease rotational speed and increase torque from an electric motor to an actuator. Cylindrical single- and double-stage (C2U, 1C2U) have an efficiency of 96–98% and are used for conveyors, mixers, and lifts. Worm gear reducers (Ch, 2Ch) are compact and self-locking, with a gear ratio of up to 80, suitable for conveyors, valves, and mixers. Bevel gear reducers (K, KC) are used to change the axis of rotation by 90°. Planetary gear reducers are designed for high torque in a compact housing (robots, extruders). Torque range: 100–500,000 N·m. GOST 20758-75 "Reducers for General Engineering Applications". Products are of Russian manufacture.
