Forming of a Functionally Tailored Hybrid Pinion Gear (T02*)

TP T2的目的是将第一个资助期的TP B3和C1的结果应用于面向应用的动态高负载演示器，其初始几何形状对应于应用合作伙伴（NSK Europe Ltd.）产品组合中的小齿轮轴。小齿轮轴预成型件由钢铝摩擦焊接半成品通过冲击挤压生产。调查的中心焦点是通过负载和使用寿命测试以及由此产生的参数与生产特定变量（摩擦焊接几何形状、成形参数等）的相关性来表征混合小齿轮轴。

The aim of TP T2 is to apply the results of TP B3 and C1 of the first funding period to an application-oriented dynamically highly loaded demonstrator whose initial geometry corresponds to a pinion gear shaft from the product portfolio of the application partner (NSK Europe Ltd.). The pinion shaft preform is produced by impact extrusion of friction-welded steel-aluminium semi-finished products. The central focus of the investigations is the characterisation of the hybrid pinion shafts by means of load and service life tests and the correlation of the resulting parameters with the production-specific variables (friction welding geometry, forming parameters, etc.).
