When honing gears, different contact conditions exist locally depending on the gear geometry and the process control. The local contact conditions directly influence the process forces and the machine excitation. The correlations have not yet been adequately described. Therefore, no statement can be made about the process stability during gear honing. The objective is derived from these general conditions.
The aim of the research project is the prediction of the excitation causes and the vibration behaviour of the gear honing process and a mapping of possible self-excited vibrations. For this purpose a process model and a machine model will be developed. Depending on the cause and form of the critical vibrations, a model of the machine is coupled with the process model. As a basis for the process model and the excitation, the contact conditions of the gear honing are transferred to an analogy process. For the tooth flank in contact, an analogy process is performed for discrete points of the involute profile of the tooth flank. The local process forces are determined. Based on this data, the honing process can be analyzed locally and temporally resolved over the tooth flank.
