  1. 11. Performance Analysis of Environmentally Adaptable Grease in Large open gears

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Victor Ogunmoye; [2022]
    Nyckelord :Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

    Sammanfattning : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. LÄS MER

  3. 12. Optimisation of tribology of Alfa Laval separator screw gear systems

    Master-uppsats, Luleå tekniska universitet/Maskinelement

    Författare :Anurag Singh; [2022]
    Nyckelord :Screw gears; Tribology; Wear; Lubrication; Materials; Surface; Roughness; Twin disc tribometer;

    Sammanfattning : Gears are machine elements essential for mechanical transmission. Wear of gear teeth can causechanges in their profile geometry, causing vibration, noise, and subsequent gear failure. In this thesisproject, a twin disc tribometer has been used to mimic the actual Alfa Laval separator screw gearsystems. LÄS MER

  4. 13. Tribology of Polymer Composite with Low Load Application for Automotive Industries

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Asuquo; [2022]
    Nyckelord :;

    Sammanfattning : In recent times, there has been an increased interest in replacing conventional metals and synthetic fiber composites in various automobile parts with natural fiber polymer composites. These natural fiber composites offer benefits over conventional materials in terms of reduction in weight, lower cost, comparable high specific properties such as specific stiffness and strength, low abrasion property, and availability of these materials.

  5. 14. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Rabia Arshad; [2022]
    Nyckelord :Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Sammanfattning : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. LÄS MER

  7. 15. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :William Tönnberg; [2022]
    Nyckelord :Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Sammanfattning : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. LÄS MER
