AI Technical Summary

Technical Problem

In the narrow space of the ship, the rust problem of the transmission shaft system or pin shaft is difficult to effectively solve by traditional methods, especially when chemical reagents cannot be used to remove rust, grinding and rust removal work is time-consuming and laborious and of poor quality.

Method used

A marine adaptive grinding and polishing device is designed, including a telescopic connecting rod, a rotating arm, a vertical swing arm and a belt tensioning component. Through the cooperation of these components, adaptive grinding of the surfaces of different diameters and curvature shafts is achieved.

Benefits of technology

This device can efficiently polish and polish the shaft in a narrow space, reduce the elastic demand for belts, ensure the quality of the grinding, and adapt to the surface of the shafts of different curvatures, improving the grinding efficiency.
