Abstract
Hydrodynamic journal bearings are essential power transmission elements for industrial rotating machineries. Continuously growing of specific power allows more compact and efficient machines, to be obtained by reducing the environmental footprint of production plants. The aim of the work is to design an innovative pad for Tilting Pad Journal Bearings with an embedded cooling circuit to limit the oil-film temperature. Heat exchange has been relevantly increased using bioinspired gyroid lattice. The complete thermo-mechanical study is performed with numerical and experimental analysis. Such a complicated geometry has been manufactured by Bound metal deposition, an innovative Metal 3D printing technology| File | Dimensione | Formato | |
