  1. 1. Intelligent fault diagnosis and predictive maintenance for a bearing ring grinder

    Author : Muhammad Ahmer; Pär Marklund; Fredrik Sandin; Kim Berglund; Martin Gustafsson; Peter Krajnik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analysis; grinding machines; diagnostics; predictive maintenance; condition monitoring; intelligent fault diagnosis; Maskinelement; Machine Elements;

    Abstract : Predicting the failure of any structure is a difficult task in a mechanical system. However complicated and difficult the prediction might be, the first step is to know the actual condition of the system. READ MORE

  2. 2. On the effects of surface roughness in lubrication

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

    Abstract : Tribology is a multidisciplinary field defined as the science and technology of interacting surfaces in relative motion, and embraces the study of friction, wear and lubrication. A typical tribological application is the rolling element bearing. READ MORE

  3. 3. Rough surface elastohydrodynamic lubrication and contact mechanics

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

    Abstract : In the field of tribology, there are numerous theoretical models that may be described mathematically in the form of integro-differential systems of equations. Some of these systems of equations are sufficiently well posed to allow for numerical solutions to be carried out resulting in accurate predictions. READ MORE

  4. 4. Modelling of wear and tribofilm growth

    Author : Joel Andersson; Rob Bosman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Wear is a consequence of nature which becomes costly if uncontrolled. Basic wear protection is provided by lubrication which will decrease the severity of the contact between asperities. READ MORE

  5. 5. Grease lubrication in radial lip seals

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

    Abstract : Rolling element bearings contain seals to keep lubricant inside and contamination outside the bearing system. These bearings are more often lubricated with grease rather than oil. Much knowledge is available on oil lubricated seals but a good understanding of grease lubricated seals is lacking. READ MORE
