AI Technical Summary
⚠Technical Problem
The heat dissipation capacity of grease is limited and its high viscosity makes it easy to accumulate impurities, leading to increased wear and maintenance frequency of the main shaft bearings of wind turbines.
⚗Method used
A lubrication device for the main shaft bearing of a wind turbine is designed. It is made of high-carbon chromium steel and undergoes quenching and low-temperature tempering treatment. It has an internal annular hollow part and ball structure, and oil slowly leaks through a narrow channel. Combined with a reinforced steel sleeve and a guide groove to collect dust, it ensures continuous flow of lubricating oil and heat dissipation.
🎯Benefits of technology
It improves lubrication, extends bearing life, reduces friction and wear, and simplifies maintenance.
