4. Analyses of Spur and Helical Gears
Abstract : 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. READ MORE
