The research of common factors in reaching a physical and mechanical condition of driveshaft crosspiece pins in feed centreless grinding in experimental and production modes

Blurtsyan D.R., Blurtsyan R.S., Blurtsyan I.R.

The paper presents the research data on establishing common factors in reaching a physical and mechanical condition of driveshaft crosspieces pin surfaces after in-feed centerless grinding both in the experimental and production modes. The assessment technique of physical and mechanical condition of the surfaces is developed. The elements of cutting modes in the context of a basic manufacturer are identified. Experimental cutting conditions providing enhanced physical and mechanical condition of the crosspiece pin surface are proved. The results of comparative tests of experimental and production grinding modes are achieved. The biggest surface tempering is provided during production grinding modes. The surface tempering almost never happens in experimental grinding mode. There are minor burns and lack of cracks in experimental grinding modes while production grinding modes cause cracking and major burns on crosspiece pin sets. Microhardness of experimentally ground subsurface increases in all horizons compared to the production mode.
Keywords: crosspieces, centerless grinding, experimental modes, production modes, microhardness.
