HUAKE
The K47 Spiral Bevel Gear Reducer is a compact, high-efficiency right-angle gearbox designed for light to medium industrial applications. Combining precision helical-bevel gearing with modular motor mounting, it offers reliable power transmission in a small footprint — ideal for packaging, conveyors, automation, and small mixing systems.
With 0.18–3 kW input power, torque up to 400 N·m, and efficiency around 97%, this model provides excellent performance for continuous or intermittent operation where space, efficiency, and noise control matter most.
Compact & Lightweight Construction
Only 20 kg, designed for easy installation in tight equipment layouts.
High Efficiency (~97%)
Spiral bevel gearing minimizes energy loss and reduces running costs.
Moderate Torque (400 N·m)
Perfect for light to medium load applications such as conveyors and mixers.
Flexible Gear Ratio (5.81–131.87)
Wide ratio range enables precise speed control and system optimization.
Low Noise & Smooth Transmission
Precision-machined gears and optimized tooth geometry ensure quiet operation.
Multiple Mounting Options
Compatible with foot-mounted, flange-mounted, or hollow-shaft configurations.
Versatile Motor Integration
Easily couples with AC, servo, or variable-frequency motors for automation and control systems.
Durable & Maintenance-Friendly
Rugged cast-iron housing and heat-treated alloy steel gears guarantee long service life.

The K47 series excels in systems where compact size, energy efficiency, and smooth transmission are key:
Conveyor & Packaging Systems – Precise speed control and quiet operation for continuous production lines.
Mixers & Agitators – Smooth low-speed performance ideal for light chemical or food blending equipment.
Automation & Robotics – Lightweight, right-angle drive ideal for compact mechanical modules.
Door & Gate Mechanisms – Stable, low-vibration operation ensures smooth opening/closing cycles.
Material Handling Systems – Reliable drive for small conveyors, rotary tables, and transfer units.
| Model | Input Power (kW) | Torque (N·m) | Efficiency | Application Focus |
|---|---|---|---|---|
| KA47 | 0.18–3 | 400 | ~97% | Light-duty automation, packaging |
| K77 | 0.37–7.5 | 1000 | ~96% | Medium-load conveyors |
| K97 | 1.1–30 | 4300 | ~97% | Heavy-duty mixing & lifting systems |
Summary:
KA47 stands out for compactness and energy efficiency, while higher models like K97 focus on torque and load capacity.
For users, K47 is ideal when space-saving, quiet performance, and stable torque are priorities.
| Application Condition | Recommended Configuration |
|---|---|
| Low-speed, precision control | Choose high-ratio (i > 100) version with servo motor for automation. |
| Continuous light-duty running | Use mid-range ratio (i = 30–60) with IE3 energy-efficient motor. |
| Limited installation space | Select flange or hollow-shaft mounting (KAF type). |
| Humid or dusty environment | Recommend IP65 protection or stainless steel shaft options. |
