对承载能力和噪声性能的要求越来越高，导致在高性能应用中使用表面硬化齿轮。为了校正热处理引起的变形并满足几何要求，表面硬化圆柱齿轮被硬加工。对于硬精加工，有几种高性能的不确定切削刃的工艺可供选择。圆柱齿轮在工业应用中的主要加工工艺有珩齿、断续成形磨齿和连续展成磨齿，珩齿主要用于模数小于mn≤ 5 mm的中小型齿轮的硬齿面精加工。由于珩齿独特的表面结构和批量生产的高经济效益，珩齿在汽车工业中得到广泛应用。以前对齿轮珩磨的研究的目的是分析模数大于mn> 4 mm的齿轮的珩磨过程的效率。在某些过程设置中，由于激励而发生稳定性问题。激励导致的结论是，有一个缺乏知识的珩磨工艺，珩磨机和工艺机器的相互作用。针对这一不足，建立了珩齿过程力的数学模型。该过程力模型基于几何穿透计算。在几何穿透计算中，刀具-工件系统被视为刚性。但在早期的研究中，已经表明，刀具和工件的弹性对切削过程有影响。因此，本文的目的是建立一种用有限元法模拟珩齿过程中工件与刀具接触区弹性的方法，通过类比的方法降低珩齿过程的复杂性。在模拟过程中，测量发生的过程力，随后将其转移到有限元模拟中。可以确定工具和工件之间的接触中的力依赖性变形。基于力和产生的弹性变形体积，计算研究区域的恒定特征值。
The increasing requirements regarding load-carrying capacity and noise behavior have led to the use of case-hardened gears in high performance applications. In order to correct distortions from heat treatment and to meet the geometric requirements, case-hardened cylindrical gears are hard finished. For hard finishing, several high performance processes with undefined cutting edges are available. The dominating processes for cylindrical gears in the industrial application are gear honing, discontinuous profile gear grinding and continuous generating gear grinding.Gear honing is primarily used to hard finish small and medium sized gears with a module less than mn≤ 5 mm. Due to the unique surface structure and the high economic efficiency in series production, gear honing is widely used in the automotive industry. The objective of previous investigations on gear honing was to analyze the efficiency of the honing process for gears with a module larger than mn> 4 mm. In some process setups, stability problems occurred due to excitation. The excitation leads to the conclusion that there is a lack of knowledge of the honing process, the honing machine and the process machine interaction. To meet this lack of knowledge, the gear honing process force was modeled. This process force model is based on a geometric penetration calculation. In the geometric penetration calculation, the tool-workpiece system is regarded as rigid. But in earlier investigations, it was shown, that the elasticity of tool and workpiece has an influence on the cutting process. Therefore, the objective of this report is to develop an approach for modeling the elasticity within the contact zone between the workpiece and the tool in the gear honing process using the finite element method.The complexity of the gear honing process was reduced by means of an analogy process. In the analogy process, the occurring process forces were measured and subsequently transferred to a finite element simulation. A force dependent deformation in the contact between tool and workpiece could be determined. Based on the force and the resulting elastically deformed volume, a constant characteristic value was calculated for the investigated area.
