The floor scrubber gearbox is a core transmission component for handheld scrubbers, commercial walk-behind scrubbers, and scrubbing robots. Featuring a fully sealed, waterproof, and dustproof design, it withstands conditions involving wastewater, moisture, and dust. It ensures stable power output for brush discs and roller brushes, delivering powerful scrubbing and cleaning performance while enabling compact, space-saving machine designs.
1. Speed Reduction & Torque Amplification: Reduces high motor speeds and multiplies output torque, ensuring stable rotation of roller brushes or brush discs under downward pressure. It effectively handles oily and stubborn stains while preventing stalling or slippage.
2. Overload Shock Protection: Features a built-in torque buffering structure that absorbs shock from overloads—such as hair entanglement or jams caused by hard objects—thereby protecting the motor and gears and reducing the overall failure rate.
3. Sealed Protection for Wet/Wastewater Environments: Utilizes a fully enclosed housing and oil seal structure to block water, moisture, dust, and wastewater splashes, making it ideal for the wet operating conditions of floor scrubbers.
4. Low-Noise, Smooth Transmission: Precision gear meshing ensures smooth power transmission, reducing operational noise and enhancing the user experience.
5. Compact Structure for Space Efficiency: Highly integrated, compact design fits into the tight brush cavities of handheld scrubbers and serves effectively as the brush drive unit for commercial scrubbers.
6. Maintenance-Free & Long Lifespan: Pre-lubricated with long-lasting grease, eliminating the need for manual lubrication and supporting the equipment's long-duration, continuous operation.
✅ High Torque Output & Stall Resistance: Optimized for ground friction and hair entanglement scenarios; maintains stable speed under heavy loads and delivers strong scrubbing power without easily stalling or shutting down.
✅ High IP-Rated Sealing for Wet/Wastewater Environments: Specialized oil seal structure effectively prevents the ingress of wastewater, foam, and dust into the gear assembly, minimizing rust and wear to withstand harsh operating conditions.
✅ Low-noise operation for an excellent user experience: Precision gear grinding ensures smooth meshing and quiet operation, making it suitable for both residential and commercial applications.
✅ High transmission efficiency for energy savings and extended runtime: Minimal transmission and power losses reduce energy consumption, thereby extending the floor scrubber's operating time.
✅ Maintenance-free with high reliability: Pre-filled with specialized grease at the factory, requiring no lubrication throughout its service life and lowering after-sales maintenance costs.
✅ Customizable design: Gear ratio, output torque, output speed, mounting interface, and protection rating can all be tailored to fit various models, including handheld residential units, commercial walk-behind scrubbers, and robotic sweepers/scrubbers.

Worm Gear Set (Bronze Worm Gear)
As core components for precision power transmission, metal gears transmit torque and regulate rotational speed through tooth-surface meshing.
Our precision plastic gears are manufactured via injection molding using high-performance engineering plastics such as POM, PA66, PA46, and PEEK.
This is a helical plastic gear featuring internal threads. Precision-molded from engineering plastic, it combines a helical gear profile on the outside with an integrated threaded hole on the inside, serving as a composite structural transmission component.
These precision injection-molded parts are designed for automotive seat adjustment motors. The complete set supports the DC motors used for forward/backward and height adjustments, serving as critical structural plastic components within the vehicle body actuation system.
Harmonic drives are widely used in industrial automation robotic arms, offering features such as high reduction ratios, high precision, compact size, lightweight design, high load capacity, low noise, and high output torque.
