Abstract: |
In this research, the strength increasing effect of nitriding was investigated on a small series of spur gears with a module of 1 mm. The nitriding process was simulated in ANSYS FEM software with DANTE heat treatment external add-on. Only a simplified transient heat treatment model was created to study the basics and the effects of nitriding on spur gears. As a result, the nitrogen distributions, the hardness of the gear tooth flanks, the residual stresses and deformations were calculated with DANTE. Approximate surface endurance limit could be calculated analytically for the analysed spur gears according to the local endurance limit formula of Kloos and Velten. As the surface endurance limit value increased because of the nitriding process, the calculated allowable torque of the driving gear also increased. Even though the higher allowable torque and the initial residual stress increased the contact stress of the gear pairs, the calculated contact stress remains acceptable. |
