Advanced Gearboxes for Machine Tools

Dongguan Fubao Precision Reducer Co., Ltd., a company specializing in the research and sales of high-precision reducers, is the only manufacturer in the world that produces cycloidal structures in harmonic dimensions.

Established in 2015, the company has applied for international patents for its micro cycloidal high-precision reducers. These reducers are widely used in various fields such as robotics and automation, machine tool manufacturing, medical systems, and research institutions.

The WF reducer adopts the cycloidal pinwheel principle and eliminates the planetary gear stage in the RV structure. It integrates high-strength crossed roller bearings, offering advantages such as high precision, low backlash, high rigidity, and compact size.

Fubao micro cycloidal reducers have the following features:

1. Low backlash

2. Ultra-high precision (transmission loss ≤ 1 arcmin)

3. Low starting torque

4. Integrated design for electromechanical integration, allowing direct connection with motors

5. Single-stage structure with large speed ratio (15~121)

6. Lightweight and compact size (starting from φ 32 mm)

Planetary gearboxes have become a key component in high-performance CNC machine tools including milling machines, lathes, grinders, drills, and machining centers. The planetary gear systems provide smooth and accurate speed/torque conversion to match the power and precision needs of various machining processes.

The compact, concentric planetary gear arrangement allows very high torque capacity within a small space envelope. This is crucial for fitting gearboxes into tight machine tool frames. Planetary gearing generates less friction and noise compared to parallel axis gears, resulting in reduced heat and vibration for smoother machining performance.

Advanced planetary gearbox technologies provide the high indexing accuracy and repeatability required for precise CNC tool positioning and contouring control. Feature sets like low backlash and high torsional stiffness enable precise start/stop, reverse, and variable load capacity – important in milling, turning, and grinding operations.

Our application-optimized planetary gearboxes are engineered for reliability and durability under harsh machine tool environments. Robust housing designs, premium bearings, and hardened steel gears ensure long service life for continuous use in high-production manufacturing.

We offer customized planetary gearbox solutions tailored to specific machine tool requirements. Our engineering expertise helps machine builders select the optimal gearbox configurations to maximize machining efficiency, precision, and productivity.

WF series - Flange Type Planetary Gear Reducer.

This gear reducer's unique design allows the load to directly act on the output flange or housing, enabling direct connection with the motor.

WFH series - Hollow Type Planetary Gear Reducer.

The distinguishing feature of this gear reducer is that wires, compressed air pipelines, drive shafts, etc., can pass through the hollow shaft.

Comparison of Fubao Gear Reducers with other manufacturers' gear reducer products:

Harmonic Gear Reducers from other manufacturers: Harmonic gear reducers are compact due to their intricate structure, but their load-bearing capacity is generally limited. They require additional bearings and have lower rigidity compared to RV gear reducers. Sliding friction exists between the wave generator, flex spline, and circular spline, resulting in significant accuracy loss and decreasing rigidity over time.

Planetary Gear Reducers from other manufacturers: Planetary gear reducers have excellent load-bearing capacity, but they are relatively larger in size. The minimum transmission loss achievable with planetary gear reducers is around 3 arc minutes. Traditional gear transmissions in planetary gear reducers involve sliding friction, leading to higher noise levels.

Fubao is the only global manufacturer that has achieved a harmonic size with the cycloidal structure of gear reducers. Our cycloidal gear reducers have the following characteristics: high rigidity, compact size, high precision, large load capacity, and long service life!
