  1. 16. Design of a Tribometer to Study Friction inThreaded Fastener Interfaces

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Zhan-Jun Lin; [2020]
    Nyckelord :tribometer; friction coefficient; tightening; pin-on-disc; tribometer; friktionskoefficient; åtdragning av skruvförband; pin-on-disc;

    Sammanfattning : Bolts and nuts are one of most common joining methods since they are simple and low-cost to connect parts. Appropriate clamp force from bolted joint remains resultant joints secured, but higher/lower preload on bolted joint increases risk of the failure of mechanism. LÄS MER

  3. 17. Mechanical dry grinding process of saw chain

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Dennis Svensson; Tobias Falk Svärd; [2019]
    Nyckelord :dry grinding; abrasive; grinding wheel; grinding disc; grinding wheel; friction; energy; work; chainsaw; saw chain; cutting link; cutting edge;

    Sammanfattning : The cutting links on chainsaws needs to be sharpened regularly to retain its sharpness. The most effective way is to use a machine wheel grinder. However, due to high friction there is a high risk of tempering the steel and damaging the sustainability to wear, resulting in a dull cutting edge. LÄS MER

  4. 18. Evaluering av självlåsande gängor

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Anton Olofsson; [2019]
    Nyckelord :;

    Sammanfattning : Thread-locking adhesive is a common component for many manufacturers, due to its protection against vibrations and slipping in screw joints. However, this does not work as desired on stainless steel materials. LÄS MER

  5. 19. Evaluations of Vibrations in a Wet Clutch

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :David Sandlund; Oskar Wintercorn; [2019]
    Nyckelord :Haldex; BorgWarner; Friction; Vibrations; Wet Clutch; Tribology; 4wd; four wheel drive; all wheel drive; awd;

    Sammanfattning : BorgWarner Powerdrive Systems is constantly developing the performance of wet clutches used in passenger car all-wheel drive systems. The Haldex limited slip coupling, LSC, is the trade name of the all-wheel drive system sold and developed by BorgWarner Powerdrive Systems. LÄS MER

  7. 20. Influence of ANS Triboconditioning on friction and fatigue in rolling contact configurations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Björn Hedmark; Per Wallgren; [2019]
    Nyckelord :Tribology; friction; fatigue; micropitting; surface engineering; twin-disc; triboconditioning; LTU;

    Sammanfattning : The automotive industry is constantly being challenged by customers and authorities to enhance the efficiency of the internal combustion engine (ICE) in order to achieve improved fuel consumption and reduced emissions. There are several interfaces within the design of an ICE that causes frictional losses, one of them is the valvetrain. LÄS MER
