Structural Design and Reliability
The two-axis servo gantry system features a semi-enclosed modular overhead structure composed of the gantry frame, drive units, lubrication system, and protective assemblies. High-quality steel profiles and plates are welded, heat-treated, and precision-machined to ensure long-term rigidity and structural stability under continuous operation.
The gantry drive system integrates AC servo motors and precision planetary gearboxes, transmitting motion through high-precision helical rack-and-pinion gears. Linear guide rails ensure smooth gantry travel and accurate robot positioning along both axes.
An automatic lubrication system supplies lubricant to critical motion components, reducing wear and extending service life. Powder-coated sheet-metal covers protect internal components from welding spatter, dust, and debris, ensuring reliable operation in demanding industrial environments.
