Abstract:
Gears are an interesting application for pressed and sintered applications, and having accurate fatigue data is often a pre-requisite for starting a new gear design. Ideally gear fatigue strength is tested on gears, but that is not always possible. At the same time standard bending fatigue data are often more readily available. Therefore, it’s interesting to have reliable methods for going from, for instance, bending fatigue strength on a test bar to tooth root fatigue strength of a gear. This paper investigates how gear fatigue strength can be calculated from test bar data and the results are compared with pulsator testing of gears.
