| Objective: | The aim of the project is to enable the design of tooth flank breakage test gears. |
| Approach: | For the design of tooth flank breakage test gearing, the main influencing variables on flank breakage are to be made available as accurately as possible in a holistic gearing model. With the shear intensity hypothesis, an equivalent to a local tooth flank breakage safety is to be calculated. The input variables of local hardness and residual stress are generated simulatively from FE models whose meshes are generated in BECAL. When the external results are available, they can be fed back to BECAL to calculate the tooth flank breakage hazard according to the current state of the art. This is to be realized for cylindrical gears as well as for bevel gears and similar gears. |
