Lubricant Replacement Frequency for Worm Gear Reducers

Importance of Lubricant Replacement:

Regular lubricant replacement is the most critical maintenance measure for worm gear reducers. It directly protects the expensive worm and wheel components from abnormal wear, high-temperature binding, and contamination-induced corrosion by providing continuous lubrication, heat dissipation, and cleaning. This practice effectively prevents sudden failures and unplanned downtime, serving as the essential "lifeline" for ensuring long-term, reliable equipment operation and avoiding costly repairs and production losses.

Key Considerations for Lubricant Replacement:

1. Initial Use & Interval: The reducer is pre-filled with lubricant upon shipment. All our worm gear reducers should have their lubricant replaced after the first 800 hours of operation.
2. Temperature Monitoring: Keep the reducer surface clean to facilitate heat dissipation. If the operating temperature exceeds allowable limits, stop the machine immediately to inspect the oil level and condition.
3. Abnormal Operation: In case of any abnormal noises or performance during operation, shut down the machine promptly for a thorough inspection.
4. Seal & Oil Level Maintenance: If oil leakage occurs due to aging or wear of rubber seals, replace them immediately. Operating with insufficient or no lubricant is strictly prohibited. The recommended lubricant type is shown in the chart below.
