Quality Control for the GWA Series Range

KUKA GWA gearboxes present specific verification challenges due to their multi-stage planetary architecture and integrated encoder interfaces. DriveKNMS applies the following test protocol to all GWA units prior to dispatch. Dimensional inspection confirms flange bolt-circle diameter (ISO 9409-1 compliance) and shaft runout within ±0.01 mm tolerance. Backlash measurement is performed using a calibrated torque arm at rated load; acceptable backlash for GWA.180 is ≤3 arcmin, GWA.210 ≤2.5 arcmin, GWA.240 ≤2 arcmin. Bearing noise analysis is conducted via vibration spectrum measurement (10 Hz–10 kHz) to detect early-stage race fatigue. Seal integrity is verified by pressurizing the gearbox cavity to 0.5 bar and monitoring for pressure drop over 10 minutes. For units with integrated resolver or RDC encoder interfaces, electrical continuity and insulation resistance (≥100 MΩ at 500 VDC) are confirmed. Each unit ships with a serialized test certificate traceable to the inspection record.
