Competition in high-end robot reducers is not just about lifespan length but about accuracy retention after long-term operation. For harmonic, RV, and other transmission systems, contact stress, manufacturing deviations, and lubrication conditions all directly affect performance degradation.
Industry Characteristics
- Numerous contact pairs with high local stresses
- Accuracy and service life are highly correlated
- Assembly deviations and process errors have significant impact
Core Analysis Scope
- Tooth flank contact stress and transmission error analysis
- Fatigue assessment of critical components such as bearings, pins, and flexsplines
- Torsional stiffness and backlash variation trend analysis
- Verification of lubrication and thermal effects on service life
Recommended Practices
Reducer simulation should not only examine static contact results under rated load, but also incorporate cyclic loading, manufacturing errors, and temperature rise factors. Only then can the accuracy degradation trend after long-term operation be evaluated.
Key Deliverables
The topic should output high-risk contact zones, primary life-controlling factors, stiffness variation trends, and process-sensitive parameters to directly support product optimization.
