  2. 1. Sustainable Lubrication and Tribotronics enabled by Ionic Materials

    Author : Akepati Bhaskar Reddy; Sergei Glavatskih; Mark W. Rutland; Nicholas Spencer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable lubrication; ionic liquid; tribotronics; lubricating grease; neutron reflectance; Machine Design; Maskinkonstruktion;

    Abstract : Developments in machine design play a crucial role in the global endeavor towards sustainability. The potential for energy conservation and emission reduction has pushed lubrication research to the forefront, with the lubricant considered to be a vital machine component. READ MORE

  4. 2. On tribological design in gear tooth contacts

    Author : Ellen Bergseth; Ulf Olofsson; Karsten Stahl; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction; gear contact; gear manufacturing; surface boundary layers; surface topography; wear;

    Abstract : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.
