  1. 1. Optimization of case-hardening depth for small gears

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Johannes Nyman; [2019]
    Nyckelord :;

    Sammanfattning : The optimization of case hardening depth for small gears was investigated with the use of Abaqus and the subroutine DANTE to simulate the formation of the microstructural phases, resulting in residual stresses and increased hardness. This was done with a step wise increment of the carburizing time, resulting in a theoretical maximum for compressive residual stresses at the surface. LÄS MER

  4. 3. DETERMINATION OF THE STRESSES PRESENT IN A HY-VO CHAIN SPROCKET USING MULTIBODY SIMULATION AND FINITE ELEMENT ANALYSIS

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Henrik Larsson; [2018]
    Nyckelord :Hy-Vo; chain; sprocket; simulation; ADAMS; fatigue; Technology and Engineering;

    Sammanfattning : In this master thesis, a new way of approaching the dynamic loads on a Hy-Vo chain sprocket was investigated and analyzed. Though the approach was not new on the market, it was new to BorgWarner, whose calculations on the matter to this date have been based on approximations. LÄS MER

  5. 4. Utveckla en FE-modell för att studera effekten av presspassning på en hypoid växelsats

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Maadhav Padmanabhan; [2017]
    Nyckelord :Hypoid gears; HFM; transmission 3D; MSC Marc; FE analysis; root bending stresses; Hypoid växlar; HFM; transmission 3D; MSC Marc; FE analys; rotböjspänningar;

    Sammanfattning : Gears are an integral part of devices ranging from simple wrist watches to complex systems like automotive and wave energy converters. They play a very important role in the transfer of torque. There are several types of gears to be chosen from, depending on the application. This thesis work deals exclusively with hypoid gears.

  7. 5. Correlation study between FEA and physical testing for a hypoid gear set

    Master-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Carl Gregefors; [2016]
    Nyckelord :;

    Sammanfattning : This thesis describes a correlation study of gear tooth bending stresses between physical testing and Finite Element modelling. It was conducted after a discovery at GKN that there were inconsistencies between the measured and calculated tooth root stresses for a hypoid gear set. LÄS MER
