  1. 11. Stress Analysis Validation for Gear Design

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Md Asif Adnan; Ahmed Shehata; [2018]
    Nyckelord :Finite element analysis; Microgeometry modification; Misalignment; Tooth contact analysis;

    Sammanfattning : Gear stress analysis and understanding the effect of misalignment and microgeometry is important for gear designers and for those who work in gear maintenance. The misalignment can lead to the higher stress acting in one side of the gear tooth and the micro-geometry modification can improve the stress distribution in the gear teeth. LÄS MER

  3. 12. Generating gear grinding : An analysis of gringing parameters's effect on gear tooth quality

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

    Författare :Emma Domare; [2018]
    Nyckelord :Generating gear grinding; Barkhausen noise analysis; X-ray diffractometry; Grinding burn;

    Sammanfattning : Generating gear grinding is a method used for hard machining of gearbox gears. It facilitates a productive gear manufacturing with tight tolerances regarding surface roughness and geometrical accuracy. LÄS MER

  4. 13. Property Optimization of PM-gearing

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Marcus Söderberg Jansson; Oskar Lundkvist; [2017]
    Nyckelord :Gear; Powder Metallurgy; Property optimization; Egenskapsoptimering; Kugghjul; Pulvermetallurgi;

    Sammanfattning : The purpose of this bachelor thesis is to design and optimize a powder metal gear through FEM-analyzes. The moment of inertia and weight of the gear shall be reduced at the same time as the demands on tension and bending stiffness are met. LÄS MER

  5. 14. Advanced hybrid manufacturing process for high precision ring of a planetary gear – main focus on Abrasive Waterjet Machining

    Master-uppsats, KTH/Industriell produktion

    Författare :BOGDAN GOTIA; JORGE LOYA MUCINO; [2016]
    Nyckelord :Abrasive waterjet machining; AWJM; precision gear; gear manufacturing; Hybrid manufacturing;

    Sammanfattning : Under år 2008 uppskattades den totala produktionen av kugghjul inom bilindustrin till 2000 – 2500 miljoner detaljer, varav 1000 - 1400 miljoner av dessa är av hög kvalité [1]. För precisionskugghjul med modul under 1 mm kan tidsbegränsning och kostnader kopplade till design av skärverktyget elimineras genom att tillämpa en flexibel tillverkningsmetod som tillexempel abrasiv vattenskärning (AWJM).

  7. 15. 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
