The KAF37-KAF157 Hard Gear Flange Output Reducer stands as a cornerstone in heavy-duty industrial power transmission, engineered to deliver high torque transmission (up to 50,000 N·m) and precise motion control across demanding operational environments. Its flange-mounted design is meticulously crafted to ensure stable installation on various machinery frames, minimizing operational vibration through optimized weight distribution and rigid structural support. This makes it an ideal choice for equipment where compact dimensions must coexist with robust performance, such as automated production lines and heavy material handlers.
At the core of its performance lies a set of hardened helical gears, which undergo a rigorous carburizing and quenching process. This thermal treatment elevates their surface hardness to 58-62 HRC—a benchmark that ensures exceptional wear resistance even under continuous high-load operation. By combining helical and bevel gear configurations, the series achieves a right-angle output that enables efficient power transfer in space-constrained settings, eliminating the need for bulky auxiliary transmission components. Its modular design further enhances versatility, supporting seamless integration with AC motors, servo motors, and asynchronous motors, while accommodating multiple mounting orientations to adapt to diverse industrial layouts.
The reducer’s cast iron housing is engineered with reinforced ribbing to withstand extreme mechanical stress, while its carburized gears feature a hardened surface layer (0.8–1.2mm depth) that resists pitting and tooth deformation. The heat-treated output shaft, crafted from 42CrMo alloy steel, undergoes tempering to achieve optimal toughness, enabling it to withstand radial loads up to 50,000 N and axial loads up to 20,000 N without permanent deformation—critical for applications like rolling mills and mining conveyors.
Advanced CNC grinding technology ensures gear tooth profiles with a surface finish of Ra 0.8μm, while computer-aided profile correction minimizes meshing interference. This precision reduces backlash to ≤20 arcmin, ensuring smooth motion transitions and consistent output accuracy—qualities indispensable for robotics, packaging machinery, and other precision-driven equipment. The integration of vibration-absorbing gaskets between housing components further lowers operational noise to ≤68 dB, creating a more worker-friendly environment.
A professional airtightness test (conducted at 0.6MPa pressure) guarantees oil-tight performance across all seal interfaces, preventing lubricant leakage even in inclined or vertical mounting positions. The reducer is pre-filled with high-performance industrial gear oil, and its design supports extended maintenance intervals (6–12 months under standard conditions), reducing unplanned downtime and operational costs. A built-in oil sight glass and drain plug simplify lubricant level checks and replacement procedures.
The KAF series excels in adaptability, offering multiple mounting positions (horizontal, vertical, or inclined) to suit complex machinery layouts. Its motor compatibility spans NEMA and IEC standard motors, with optional adapter flanges for non-standard models. The inclusion of shrink disc and splined hollow shaft options eliminates the need for time-consuming keyway machining, enabling quick and secure coupling with driven equipment such as pumps, mixers, and conveyors.
Metallurgy: Essential for rolling mills (controlling strip tension), continuous casting machines, and coil handling systems
Mining: Powers crushers (jaw, cone, and impact types), ore processing equipment, and underground conveyor belts
Chemical Industry: Drives mixers for high-viscosity materials, reactor agitators, and chemical transfer pumps
Food & Beverage: Integrates with packaging lines (carton formers, fillers), bottling machines, and food-grade conveyors
Automation: Supports robotics (pick-and-place arms), material handling systems, and automated storage retrieval units
