  1. 6. 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

  3. 7. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Caroline Lejonklo; [2019]
    Nyckelord :Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Sammanfattning : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  4. 8. Modeling of a Gear Test Rig : An Investigation of Static Loads and Dynamic Excitation of Vibrations

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Albin Hugoh; [2019]
    Nyckelord :;

    Sammanfattning : Today the automotive industry is going through big changes and facing many new challenges due to the transformation to a sustainable transport solution in combination with tougher legal demands. Gears have been around for a long time and it is one of the most efficient ways of transferring rotary motion from one shaft to another. LÄS MER

  5. 9. Dynamic simulation of a planetary gear for robots

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Xiaohao Qin; Jiahao Cheng; [2019]
    Nyckelord :dynamic simualtion; robots; PGT; solidworks; MATLAB;

    Sammanfattning : Gear drives are widely applied in mechanical transmission systems and very accurate transmission systems are needed. In the robot industry, the planetary gear train (PGT) is commonly used to promote the torque transmission. One of the advantages of an ideal PGT is that the incoming torque is divided equally among the planet gear wheels. LÄS MER

  7. 10. Integrated generator for use in aircraft engines

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fredrik Andersson; [2018]
    Nyckelord :Integrated generator; aircraft engine; generator; aircraft generator; Technology and Engineering;

    Sammanfattning : In this paper the use of integrated generators for airplane engines is examined. In order to accomplish this goal a combination of MatLab with FEMM and ANSYS Maxwell is used to make incrementally more and more detailed analysis of the integrated generator concept. LÄS MER
