AI Technical Summary

Technical Problem

The special-shaped tapered rollers used for processing the central flange of offshore wind turbines have experienced a decline in fitting accuracy due to wear and the entry of impurities during long-term use, which affects the rolling effect and increases maintenance costs.

Method used

A special-shaped rolled conical roll for the bottom flange of a wind turbine is designed. By setting an annular groove on the inner wall of the conical roll sleeve to embed solid lubricating blocks, and by using structures such as convex rings, retaining rings, and reinforcing rings, the conical roll shaft and the conical roll sleeve can be quickly and accurately positioned and uniformly lubricated, preventing impurities from entering the gap.

Benefits of technology

It improves the connection between the tapered roller sleeve and the tapered roller shaft, extends service life, reduces wear and maintenance frequency, and simplifies the operation process.
