1. On the influence of surface roughness on rolling contact forces
Sammanfattning : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.

2. Cam Roller Contact
Sammanfattning : The automotive industry and the design of engines are strongly ruled by performance andlegislation demands. First order aspects defining the main functions of a component are wellknown and new challenges appear at a lower scale. LÄS MER

4. On Rolling Variators, A study of power transmitting rolling variators when changing speed ratio
Sammanfattning : The introduction of the concept Rolling Variators is proposed for rolling contact continuously variable transmission.A theoretical study of rolling variators when changing the speed ratio during power transmission is presented. LÄS MER
5. Analyses of Spur and Helical Gears
Sammanfattning : The thesis contains three papers that comprise studies of the dynamic behaviour of involute spur and helical gears, and one paper that describes a method to determine the influence of misalignment on the static helical gear tooth stress. In the first study, the influence of the contact ratio on the dynamic response of a spur gear was examined. LÄS MER
