Increase in wear resistance of misaligned screw mechanisms by the technological procedures

A model experiment is planned and realised to determine an effective procedure to manufacture the parts of misaligned screw mechanisms. The experiment is based on comparing the wear resistance of the threaded profiled parts that were thermally processed and then grinded, with the knurled profiles operating under similar conditions. The experimental data are presented substantiating the advantages of manufacturing the parts by the thread rolling method as compared with traditional procedure combining the thermal processing with subsequent thread grinding.
