1. Gear Surface Machining for Noise Suppression
Sammanfattning : 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. Influence of running-in on gear efficiency
Sammanfattning : The general trend in gear industry is an increased focus on gear transmission efficiency. This thesis focuses on the understanding of how different gear manufacturing methods – particularly the contribution of the running-in process – affect the surface characteristics and friction response, with the purpose of increasing gearbox efficiency.

3. On the running-in of gears
Sammanfattning : The general trend in gear industry, today, is an increased focus on gear transmission efficiency. Gear transmission efficiency losses arise from loaded and unloaded gear contacts, seals, lubricant and bearings. One way of minimising the losses is to lower the lubricant viscosity. This will reduce the speed dependent losses. LÄS MER
