AI Technical Summary

Technical Problem

The existing wind turbine gearbox oil collecting box cannot effectively filter impurities and metal debris in the oil, resulting in reduced gear oil performance and increased wear.

Method used

A wind turbine gearbox oil collecting box is designed, which includes a ring-shaped oil collecting module, a filter box placement rack, a heating wire and an anti-clogging needle. It can filter out metal particles and impurities in the lubricating oil and prevent the lubricating oil from solidifying and clogging in low temperature environments.

Benefits of technology

Effectively remove metal particles and impurities in the lubricating oil, reduce the frequency and cost of oil changes, prevent the oil box from clogging, ensure the lubricating oil flows smoothly into the gearbox, reduce the risk of leakage, and keep the gearbox clean.
