  4. 2. Gearbox noise : Correlation with transmission error and influence of bearing preload

    Author : Mats Åkerblom; Sören Andersson; D. Houser; KTH; []
    Keywords : gear; gearbox; noise; vibration; transmission error; bearing preload; Mechanical engineering; Maskinteknik;

    Abstract : The five appended papers all deal with gearbox noise and vibration. The first paper presents a review of previously published literature on gearbox noise and vibration. The second paper describes a test rig that was specially designed and built for noise testing of gears. READ MORE

  5. 3. Gear Surface Machining for Noise Suppression

    Author : Naser Amini; Chalmers University of Technology; []
    Keywords : gear grinding; gear shaving; gears; undulation; surface topography; noise; automotive gearboxes; ghost harmonics; gear honing;

    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.

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

    Author : Mattias Svahn; Maskinelement; []
    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

  7. 5. Simulation of contact, friction and wear in gears : a finite element approach

    Author : Olle Lundvall; Linköpings universitet; []
    Keywords : Gears; Gear noise; Contact mechanics; Simulation; Friction; Wear; Transmission error;

    Abstract : In this thesis, resent methods in computational contact mechanics is brought into the process of gear design. The finite element method is used to model two elastic bodies in contact. By defining a contact interface between these two bodies, constitutive laws, regarding normal contact, friction and wear, are included. READ MORE
