An industrial gearbox is a system assembled from gears that transmits mechanical energy from a prime mover to an output device; typically, during this transmission process, it alters the speed, direction, or torque of the input energy.

Industrial gearboxes feature a modular design that allows for the integration of backstops to enable unidirectional transmission, as well as the configuration of auxiliary transmission units in series. The power transmission range spans from 0.12 kW to 200 kW, offering precise transmission ratios covering a selectable range of 3.77 to 281.71. The gears undergo high-precision grinding on specialized machines, ensuring smooth transmission, low noise levels, and an inter-stage efficiency of up to 98%. Specifically designed for applications requiring extremely low speeds, a specialized dual-unit reducer configuration is available that can extend the overall transmission ratio-when paired with a compatible geared motor-up to 31,434.

The primary materials used in these industrial gearboxes include: the housing, which is typically constructed from cast iron; the gears, which are made from 20CrMo steel and undergo carbon-nitrogen co-nitriding treatment (maintaining a tooth surface hardness of HRC60 and a hardened layer depth of >0.5 mm after precision grinding); and the parallel keys, which are made from 45 steel.

Common mounting configurations include horizontal mounting, vertical mounting, shaft mounting, and mounting utilizing a locking disc.
