  4. 2. Transient elastohydrodynamic lubrication : Effects of geometry, surface roughness, temperature, and plastic deformation

    Author : Tobias Hultqvist; Roland Larsson; Pär Marklund; Wassim Habchi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The urgent need to reduce greenhouse gas emissions in combination with an increased use of sustainable energy resources have led to immense efforts on improving energy efficiency of mechanical systems. Consequently, modern machine elements are typically lubricated with low viscosity oils and designed to endure an increasingly high power density. READ MORE

  5. 3. Water-based hydraulic fluids : rheology and elastohydrodynamic lubrication

    Author : Ove Isaksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Maskinelement; Machine Elements;

    Abstract : Experiments have been carried out to measure traction, antiwear and rheological properties of water-based hydraulic fluids. Four types of fluids have been examined, emulsions, micro-emulsions, synthetic solutions and water-glycols. READ MORE

  6. 4. Friction in Elastohydrodynamic Lubrication

    Author : Marcus Björling; H. P. Evans; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Today, with increasing demands on industry to reduce energy consumption and emissions, the strive to increase the efficiency of machine components is maybe bigger than ever. This PhD thesis focus on friction in elastohydrodynamic lubrication (EHL), found in, among others, gears, bearings and cam followers. READ MORE

  7. 5. Grease in elastohydrodynamic lubrication

    Author : Henrik Åström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The rheology of soap thickened greases has been investigated in a cone and plate rheometer and a model that includes base oil viscosity and temperature has been suggested and fitted to the results. With the use of a bouncing ball apparatus, the pressure coefficient of the limiting shear stress of the greases was determined. READ MORE
