  2. 1. Gear Surface Machining for Noise Suppression

    Author : Naser Amini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.
