  3. 3. Gear Surface Machining for Noise Suppression

    University dissertation from Chalmers University of Technology

    Author : Naser Amini; Chalmers tekniska högskola.; Chalmers University of Technology.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering mechanics; automotive gearboxes; gears; noise; surface topography; undulation; ghost harmonics; gear grinding; gear honing; gear shaving;

    Abstract : Gear noise in modern automobiles is unacceptable. It has different sources, such as design parameters and manufacturing errors. Manufacturing errors, for example, can be reduced using advanced grinding operations. However, sometimes grinding operations can introduce micro-geometry deviations that cause severe noise problems.

  4. 4. On the Machining of Involute Helical Gears - Prediction models on tool geometry, cut gear tooth surface topography, chip geometry, and tool cutting forces

    University dissertation from Chalmers University of Technology

    Author : Mattias Svahn; Lunds universitet.; Lund University.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gear hobbing; Gear milling; Chip geometry; Cutting forces; Surface topography; Tool wear;

    Abstract : The modern requirements on power transmissions focus on energy efficiency, low noise and dynamic vibrations, and power density. In order to meet these requirements, the gear wheels must be manufactured to very high precision. Additionally, it should be economical to manufacture these gears within the tight requested tolerances. READ MORE

  5. 5. Tooth Interior Fatigue Fracture&Robustness of Gears

    University dissertation from Stockholm : Maskinkonstruktion

    Author : Magnus MackAldener; KTH.; [2001]

    Abstract : The demands the automotive gear designer has to considerduring the gear design process have changed. To design a gearthat will not fail is still a challenging task, but now lownoise is also a main objective. Both customers and legalregulations demand noise reduction of gears. Moreover, thequality of the product is more in focus than ever before. READ MORE
