Regular Maintenance of Planetary Gearboxes

Regular maintenance is crucial to ensure the smooth operation and longevity of planetary gearboxes. Here are the key maintenance tasks to be carried out:

1. Cleaning and Inspection of Equipment

• Task: Regularly clean the planetary gearbox and its lubrication system.
• Details: Strictly adhere to the operating procedures. Promptly address minor issues such as loose fasteners or minor defects in the gearbox.
• Record-Keeping: Properly document maintenance activities and fill out the required operational logs. Ensure that handover protocols are followed during shift changes.

2. Vibration, Temperature, and Noise Checks

• Vibration: During inspections, check whether the planetary gearbox exhibits any abnormal vibration under normal load conditions.
• Temperature Monitoring: Ensure that all bearing temperature indicators are operating within the specified limits.
• Lubrication System: Verify that the oil supply pressure and flow rates meet the system’s requirements.
• Noise: Listen for any unusual noises from the gearbox. Unusual sounds could indicate internal issues such as wear or imbalance.
• Electrical and Mechanical Checks: Inspect electrical components and mechanical parts for any unusual odors, which may indicate overheating or other problems.

3. Inspection During Long-Term Shutdown

• Dust and Rust: For planetary gearboxes that remain idle for extended periods, pay special attention to dust ingress and potential rust formation. It is important to prevent moisture and contaminants from accumulating, as they can degrade the system.
• Monthly Start-Up: Start the gearbox at least once a month. Run it for about 1 hour to ensure the components are functioning correctly.
• Observation: Through the observation window and side cover, inspect the condition of gears and bearing supports for any signs of rust or wear.
