COMPLEX METHOD OF THE ANALYSIS OF GEOMETRICAL ACCURACY OF CYLINDERS DURING THE ASSEMBLING OF SHIP LOW-SIZED DIESEL ENGINES
Geometrical accuracy of cylinders bushings from the cylinder-piston group of ship low-sized diesel engine is investigated in the paper. The permanent factors resulting in deviations of geometrical accuracy of cylinders are determined. The technique of a complex experimental research of geometrical accuracy of cylinders bushings, formed while the assembling of ship low-sized diesel engines, is developed. The way to receive visual characteristics of contact pressure on supporting ledges of cylinders bushings influencing their elastic deformations, is developed and applied for the first time. Methods helping to reduce shape defects of cylinders apertures - known in design-technological practice, and some new, demanding to carry out special research to confirm their efficiency, are shown.
