  1. 1. Diesel Engnine Cam and Roller Follower Tribology

    Författare :Martin Olsson; Maskinelement; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Cam; Roller follower; Mechanical engineering; Damage progress; Running in; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : Surfaces subjected to rolling and sliding contacts may suffer from contact fatigue. The cam and roller follower mechanism is a typical rolling and sliding contact. LÄS MER

    Nyckelord :cam; follower; valuve train; diesel engine; friction; wear;

    Sammanfattning : .... LÄS MER

  4. 3. Elastohydrodynamic Lubrication of Cam and Roller Follower

    Författare :Mohammad Shirzadegan; Jonas Ståhl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Modelling and simulation of friction is a research issue that still requires an extensive amount of input from the scientific community. In a lubricated system, the dissipation of energy is connected to the direct contact between the surfaces, or more precisely the tribofilms, as well as of the shearing of the lubricant film. LÄS MER

  5. 4. Elastohydrodynamic Lubrication of Cam and Roller Follower Applications : Fast and Reliable Predictions of Friction

    Författare :Mohammad Shirzadegan; Daniele Dini; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : Modelling and simulation in tribology, and more specifically of friction in lubricated contacts, has gained increasing attention over the past years. In a lubricated contact, the dissipation of energy is due to the relative motion of the mating surfaces and arise due to direct contact as well as shearing of the lubricant film. LÄS MER

  7. 5. Wear resistant low friction coatings for engine components

    Författare :Per Lindholm; Sören Andersson; Rickard Larker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering materials; cam; roller follower; carbon coating; engine test; finite element method; Konstruktionsmaterial; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Engine development today is driven by cost, performance and government regulations. Customers want cars and trucks to consume less fuel, last longer, pollute less and be safer. Several of the requirements have tribological associations. For example, product longevity can be improved by lowering friction and using more wear-resistant components. LÄS MER
