  1. 21. The technology of processing antimony-bearing ores

    Författare :Thomas Lager; []
    Nyckelord :;

    Sammanfattning : Several aspects of the process technology for treatment of antimony-bearing ores have been studied. The feasibility of separating contaminant antimony minerals as early as the mine planning stage is discussed. LÄS MER

  3. 22. Mechanical behaviour of a roller bearing steel : Strength differential effect, low temperature creep and propagation of short cracks

    Författare :Irene Linares Arregui; Bo Alfredsson; Nils-Gunnar Ohlson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Fatigue cracks in bearings either initiate from the surface or from an inclusion below the rolling contact surface. Then, short cracks start to propagate. Short crack grow at considerably faster rates than long cracks subjected to a nominally equivalent stress intensity factor range. LÄS MER

  4. 23. Slender precast systems with load-bearing façades

    Författare :Karin Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : .... LÄS MER

  5. 24. Tribology of Rolling-Sliding Contacts under Mixed Lubrication : With focus on a Crankshaft Roller Bearing Application

    Författare :Aleks Vrček; Pär Marklund; Roland Larsson; Amir Kadiric; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : A continuous increase in environmental legislation to reduce CO2 emissions is forcing engineers and scientists to develop more efficient and durable mechanical components, i.e. bearings, crankshafts, gears, etc. LÄS MER

  7. 25. Tribological Behaviour of Pb-free Engine Bearing Materials

    Författare :Daniel Gebretsadik; Donald McCarthy; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Engine bearings are amongst the most critical components of an internal combustion engine that support and allow smooth rotation of the crankshaft. They are designed to operate under hydrodynamic lubrication condition where the bearing and shaft surface are separated by a thick lubricant film. LÄS MER
