Engineering Guide: Slew Ring Drive Selection & Maintenance
5-Step Selection Process
1. Load Analysis
Formula: P0 = Fa + 2.5Fr
Where Fa = Axial load, Fr = Radial load
2. Environmental Factors
Offshore: ISO 12944 C5-M coating
Mining: Hardened gear teeth (60+ HRC)
Arctic: -50°C lubricants
Predictive Maintenance Techniques
- Vibration Analysis: Detect gear pitting at early stage
- Oil Debris Monitoring: ISO 4406 particle count
- Thermography: Identify abnormal friction points
