Industrial robot project

I. Project Overview

A Brazilian automotive parts manufacturer deployed multiple six-axis robotic workstations for tasks including metal casting loading/unloading, workpiece grinding, and finished product palletizing/transfer. The factory environment features high dust levels and significant load fluctuations; the robots operate with frequent high-speed directional changes and impact loads. All robot joint drives are equipped with our company's heavy-duty Planetary Gearboxes.

II. Project Pain Points

1. The original gearboxes lacked sufficient rigidity, causing vibration and deviation during high-speed oscillation and directional changes; this resulted in inaccurate workpiece positioning and inconsistent grinding quality.

2. Casting handling involves instantaneous impact loads; standard gears suffered from rapid tooth surface wear, leading to frequent equipment failures and high spare part replacement costs.

3. The dusty South American factory environment overwhelmed the gearboxes' dust protection capabilities; dust ingress accelerated internal wear, resulting in a heavy maintenance workload.

4. The original gearboxes were too bulky; the robot's compact structure limited installation space, making it difficult to modify the overall equipment layout.

III. Solution

1. High-rigidity, integrated planetary gear architecture with minimal backlash suppresses high-speed motion vibration and ensures repeatable positioning accuracy.

2. Reinforced heavy-duty, impact-resistant gear materials enhance instantaneous overload capacity, making them suitable for the impact-heavy conditions of casting handling.

3. High-protection sealing structure blocks workshop metal dust from entering the internal gear assembly, extending the service life of internal components.

4. Compact design with high torque density offers a smaller footprint for the same torque output, fitting perfectly into the robot's tight joint installation spaces without requiring structural modifications to the robot itself.

IV. Project Value

1. Robots operate smoothly without vibration; precision in gripping and grinding processes is consistent, reducing the number of defective workpieces.

2. Impact-resistant and wear-resistant structures significantly reduce gearbox failure rates, leading to substantial savings on spare parts and maintenance labor.

3. Dust-proof sealing adapts to harsh workshop conditions, ensuring stable year-round operation and continuous factory production.

4. The compact structure simplifies the robot's overall design, shortens the implementation cycle for equipment upgrades, and enhances the market competitiveness of the customer's equipment.
