Advanced Design of a Novel Needs-Based Lubrication Method for Gears
- Lehrstuhl für Maschinenelemente
- experimentell theoretisch konstruktiv
Different lubrication methods such as oil injection lubrication are used in geared transmissions to lubricate tribocontacts and to dissipate frictional heat. To improve resource and energy efficiency, novel needs-based lubrication methods like the dropondemand lubrication are being developed. It is based on an ink-jet nozzle driven by a piezo element to generate picoliter droplets injected to tribocontacts.
First investigations have shown the feasibility of such drop-on-demand lubrication of gears. On this basis, the goal of the project is to investigate the optimal injector position and droplet frequency for gear lubrication. Therby, the influence of air flow around rotating gears needs to be considered. As part of your work you will work with drop-on-demand printing systems in the lab. Useful measurement technology and simulation tools are available.
