  1. 1. TEMPERATURE MODELLING OF GEAR MESH

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ahsan Kadevalappil Ajilan; [2023]
    Nyckelord :Helical gear; Power loss; MATLAB; ANSYS; Spiralväxel; Strömförlust; MATLAB; ANSYS;

    Sammanfattning : Temperature control is an essential aspect of gear design. Continuous research is going on to improve the efficiency of gear systems. Power losses or energy losses in these systems typically manifest themselves as increased temperatures and thus reducing the lifetime and overall performance of the system. LÄS MER

  4. 3. An Investigation on the Suitability of Abrasive Waterjet Cutting for Hybrid Manufacturing of Gears in Automotive Industry

    Master-uppsats, KTH/Industriell produktion

    Författare :Vusal Babashov; Gunel Mammadova; [2015]
    Nyckelord :;

    Sammanfattning : Gears are components in mechanical assemblies used for transmitting power and motion. Gear form cutting (broaching, milling) and gear generating (shaping and hobbing) are two of the main gear manufacturing methods. Usually production involves three stages: (i) soft machining, (ii) heat treatment, and (iii) hard machining. LÄS MER

  5. 4. Meta Modeling of Transmission Error for Spur, Helical and Planetary Gears for Wind Turbine Application

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Muhammad Irfan; [2013]
    Nyckelord :Transmission error; Wind turbine; Meta-models; Abaqus 6.12-1; Spur gear; Helical gear; Planetary gear; Regression analysis.;

    Sammanfattning : Detailed analysis of drive train dynamics requires accounting for the transmission error that arises in gears. However, the direct computation of the transmission error requires a 3-dimensional contact analysis with correct gear geometry, which is impractically computationally intense. LÄS MER

  7. 5. Elastohydrodynamic lubrication in spur gear and helical gear contacts

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Sudeendra Chitta; [2012]
    Nyckelord :Gears; lubrication;

    Sammanfattning : The gears in a transmission are lubricated to prevent their premature failure as a result of pitting and wear on the tooth surfaces. Furthermore, the lubricant also limits the rise in surface temperature of the gears, which could otherwise lead to failure as a result of scuffing. LÄS MER
