How to Reactivating A Planetary Gearbox After Long-term Storage?

When dealing with a planetary gearbox that has been in long-term storage, there are several important considerations to ensure its proper functioning:
 

Visual Inspection

Carefully inspect the gearbox for any signs of corrosion, rust, or physical damage.
Check for any signs of moisture, condensation, seal deterioration or leakage.
 

Pre-use Check

Clean the entire gearbox thoroughly.
Perform a test run at low speed for about half an hour before full operational use.
Check for unusual noise, vibration, or heat during initial operation.

Long-term or extended storage of the planetary gearbox without use may cause lubricant degradation, where the oil or grease inside the gearbox deteriorates over time. This can lead to increased friction, wear, and stress on key components such as pinion inside the gearbox, and result in damage in a short time. Running the gearbox with low speed before installation in such case helps redistribute the lubricant throughout the gearbox, ensuring it properly coats all moving parts and reducing the risk of dry starts. Additionally, test run allows for the detection of any early signs of mechanical issues such as unusual noise, vibration, or overheating that could point to internal problems.

By taking these preventive steps, you can minimize the risk of future failures and ensure the gearbox operates smoothly even after extended periods of storage. Besides, the planetary gearbox storage conditions does matter. If it is stored in a dry, climate-controlled environment, chances of good preservation are higher. Humid or extreme temperature conditions increase risk of internal degradation. If stored in challenging conditions, more extensive inspection and potential repair might be necessary.
