Investigations on Oil Flow Rates Projected on the Casing Walls by Splashed Lubricated Gears

الملخص EN

In order to investigate the oil projected by gears rotating in an oil bath, a test rig has been set up in which the quantity of lubricant splashed at several locations on the casing walls can be measured.

An oblong-shaped window of variable size is connected to a tank for flow measurements, and the system can be placed at several locations.

A series of formulae have been deduced using dimensional analysis which can predict the lubricant flow rate generated by one spur gear or one disk at various places on the casing.

These results have been experimentally validated over a wide range of operating conditions (rotational speed, geometry, immersion depth, etc.).
