  1. 1. Effect of water contamination on the diffused content of hydrogen under stress in AISI-52100 bearing steel

    University dissertation from Lund University (Media-Tryck)

    Author : Tajammal Imran; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; materialteknik; Materiallära; Material technology; Hydrogen Diffusion; Rolling Element; Machine Elements; Tribology; Hydrogen Embrittlement; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Popular Abstract in Swedish Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. READ MORE

  2. 2. Analyses of Spur and Helical Gears

    University dissertation from Machine Elements, LTH, Box 118, 221 00 LUND

    Author : Anette Andersson; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; hydraulics; Teknik; Mechanical engineering; Technological sciences; misalignment; contact ratio; load distribution; transmission error; tooth contact analysis;

    Abstract : The thesis contains three papers that comprise studies of the dynamic behaviour of involute spur and helical gears, and one paper that describes a method to determine the influence of misalignment on the static helical gear tooth stress. In the first study, the influence of the contact ratio on the dynamic response of a spur gear was examined. READ MORE

  3. 3. On the Load Distribution and Design of a Chain Drive

    University dissertation from Machine Elements Division, P.O.Box 118,SE- 22100 Lund,Sweden

    Author : Ingvar Troedsson; Lunds universitet.; Lund University.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. READ MORE

  4. 4. Diesel Engnine Cam and Roller Follower Tribology

    University dissertation from Division of Machine Elements, Department of Mechanical Engineering, Lund Institute of Technology

    Author : Martin Olsson; Lunds universitet.; Lund University.; [2006]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Mechanical Analysis of Lubrication and Lubricants

    University dissertation from Division of Machine Elements, Department of Mechanical Engineering, Lund Institute of Technology

    Author : Jonas Ståhl; Lunds universitet.; Lund University.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; Maskinteknik; hydraulik; akustik; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering;

    Abstract : This thesis comprises three different topics within the field of tribology. First, design functions for analyses of slider bearings are developed. Second, a lubricant model applied to elastohydrodynamically lubricated (EHL) line contacts considering wall-slip is presented. READ MORE
