Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Gearbox backlash and wear
Cause: Inadequate lubrication, contamination ingress, or excessive cyclic loading leading to pitting, spalling, and increased positional error
Encoder or resolver signal degradation
Cause: Electrical noise interference, thermal drift, mechanical misalignment, or aging of optical/ magnetic components causing loss of positional feedback accuracy
Maintenance Indicators
  • Unusual grinding, clicking, or whining noises from joints during motion, indicating gear wear or bearing failure
  • Erratic or 'jumpy' arm movement, drift from programmed positions, or servo fault alarms suggesting feedback or drive system issues
Engineering Tips
  • Implement condition-based lubrication with high-purity, manufacturer-specified greases and monitor particle counts in gearbox oil to prevent abrasive wear
  • Regularly calibrate and align encoders/resolvers, ensure proper shielding and grounding of feedback cables, and maintain stable ambient temperature to preserve positional accuracy
