The KF37-KF157 High-efficiency Spiral Bevel Gear Reducer emerges as a premium solution for applications demanding precision motion control and high-power transmission in right-angle configurations. Its defining feature—spiral bevel gears—is engineered with a unique curved tooth profile that ensures gradual meshing, distributing load across multiple teeth to minimize stress and reduce noise. This design, paired with hardened tooth surfaces (58–62 HRC), delivers exceptional durability and smooth operation even in high-cycle industrial environments.

Product Overview


Designed with versatility in mind, the reducer features a flange-mounted design that provides stable installation on machinery frames, while its modular system allows customization of torque capacity, mounting orientation, and output shaft type to meet specific application needs. Whether powering precision robotics or heavy mining equipment, the KF series balances efficiency (94%–96%) and reliability, making it a preferred choice for industries where operational downtime is costly.


Product Features


Spiral Bevel Gear Technology

The spiral bevel gears are manufactured using five-axis CNC machining centers, ensuring tooth profiles with micron-level accuracy. Their curved design enables concurrent meshing of 2–3 teeth (compared to 1–2 teeth in straight bevel gears), distributing load evenly and reducing vibration. This technology minimizes backlash to ≤20 arcmin in standard models, making it suitable for high-speed applications (up to 3,000 RPM input) requiring precise positioning, such as CNC machine tools and robotic arms.


High Efficiency

With 94%–96% efficiency, the KF series outperforms traditional worm gear reducers by 15–30% in energy savings. Its low friction design—achieved through optimized gear geometry and high-precision bearings—reduces heat generation, extending lubricant life to 12–24 months under standard operating conditions. This efficiency translates to lower energy costs and reduced cooling requirements, particularly beneficial for continuous-operation facilities.


Sealed for Harsh Environments

The reducer features double-lip oil seals (made from nitrile rubber) that prevent lubricant leakage and block contaminants, while its IP65-rated housing provides protection against dust ingress and low-pressure water jets. This rugged sealing system makes it suitable for outdoor applications (e.g., construction machinery) and corrosive environments like chemical plants and coastal facilities. For extreme conditions, optional IP66/IP67 upgrades and stainless-steel components are available.


Easy Maintenance

The split housing design allows quick access to internal components (gears, bearings, seals) without removing the reducer from the machinery frame, significantly reducing inspection and repair time. A sight glass on the housing simplifies lubricant level checks, while a magnetic drain plug captures metallic debris to prevent gear contamination. Maintenance intervals are extended through the use of lifelong lubricated bearings and high-stability industrial gear oil.


Applications


Automotive: Powers testing rigs (durability, torque, and speed testing), assembly line conveyors, and robotic welding stations

Aerospace: Drives actuators for flight control systems, flight simulators, and component testing equipment

Pharmaceuticals: Operates mixing tanks (for drug formulation), tablet presses, and sterile packaging machinery

Mining: Equips ore crushers, conveyor drives, and mineral processing equipment in underground and surface mines

Robotics: Supports automated guided vehicles (AGVs), collaborative robots (cobots), and precision pick-and-place systems

Q: What is the backlash of the KF series?

A: Standard models feature backlash of ≤20 arcmin, suitable for most industrial applications. For precision-critical scenarios (e.g., CNC machining, robotics), we offer a low-backlash version with backlash ≤10 arcmin, achieved through tighter gear meshing tolerances and post-assembly lapping processes.

Q: Can the reducer be mounted vertically?

A: Yes, the KF series supports vertical mounting with specific lubrication adjustments. In vertical orientations, we recommend using a forced lubrication system or modifying the oil sump to ensure adequate gear and bearing lubrication. Contact our technical team for a customized lubrication plan based on your mounting angle and operating conditions.

Q: What is the temperature rise limit?

A: Under full-load operation, the maximum allowable temperature rise is 40°C (measured from ambient temperature). For applications with high duty cycles (≥80% continuous load) or ambient temperatures above 40°C, consider the KFZ series—equipped with enhanced cooling fins, larger oil capacity, and optional oil coolers to manage heat buildup.

Q: Are explosion-proof versions available?

A: Yes, we offer ATEX-certified models (II 2G Ex d IIB T4 Gb and II 2D Ex tD A21 IP65 T130°C) for hazardous environments containing flammable gases, vapors, or dust. These feature flameproof housings, non-sparking components, and thermal protection to prevent ignition sources. Provide your application’s hazard zone classification for a tailored quote.

Q: How to select the correct lubricant?

A: For standard conditions, use synthetic gear oil (ISO VG 220–460) with extreme pressure (EP) additives. In cold environments (-10°C to 0°C), ISO VG 220 ensures proper flow; in high temperatures (40°C+), ISO VG 460 maintains viscosity. For food-grade applications, NSF H1-certified lubricants are available to meet safety standards.
