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

点击翻译按钮获取中文摘要

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.).
