Study Of On-Line Inspection Method Of Oversize And High Precision Bearing

摘要

According to high precision and oversize bearing's characteristics of large size, heavy weight and high precision, on-line inspection method based on contact measuring method is proposed. This inspection method uses contact double rotation probe and separates rotation error of machine tool through error separation technology, which realizes the continuous on-line measurement of inner and outer diameters, roundness and cylindricity of oversize bearing. Take the spindle bearing of large-scale CNC horizontal lathe for example, the inspection result shows that the precision meets the P4 standard, which satisfies precision test as well as provides theoretical foundation and technique support for the improvement of the accuracy of the oversize bearing.
