1. Gear Surface Machining for Noise Suppression
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.

2. Gear tribology : friction and surface topography
Abstract : The quest for energy efficiency leads to the development of highly efficient power transmissions for vehicles. Gears are some of the most rugged and durable torque transmitters among machine elements. Friction between sliding surfaces at gear teeth is one major source of power loss. READ MORE

3. On tribological design in gear tooth contacts
Abstract : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.
