Research of the Innovative Method of Using Gear Gears

Abstract

The present thesis is a summary of research result on an innovative manufacturing method for production of PM gears for application in heavy vehicle. The method uses a powder metal densifications process route to ensure full density.
The thesis addresses three research questions. First the feasibility of reaching full density for a gear constructed of standard modules relevant for heavy vehicles is investigated. Then the effect of gear geometry on the PM processing is studied. It is revealed that gear geometry influences the density distributions hence the final result. Therefore, the part of the research focusing on the relationship between gear dimensions and the densification results is conducted.
