Section 1: Installation Precautions
Base Preparation
Ensure mounting surface flatness ≤0.02mm/m
Bolt pre-torque sequence follows manufacturer's cross-pattern specification
Alignment Check
Use dial indicator to verify TIR (Total Indicator Reading) ≤0.05mm
Section 2: Daily Maintenance
Item | Frequency | Standard |
---|---|---|
Lubrication | 500hrs | NLGI Grade 2 lithium grease |
Bolt Inspection | Monthly | Torque variation ≤10% |
Section 3: Troubleshooting
Abnormal Noise: Check gear meshing clearance (0.1-0.3mm)
Vibration: Verify raceway surface roughness Ra ≤1.6μm
Section 4: Extended Service Life Techniques
Implement condition monitoring via vibration analysis
Use synthetic grease for -30℃~150℃ applications
