Add oil circulation to Gear and Bearing sumps for greater reliability

摘要

The designs of many common machine mechanisms have not changed significantly in decades (centuries in some cases). This is especially true where lubrication is involved. Apparently, machine designers working for original equipment manufacturers (OEMs) are under the impression that lubrication has not been, or simply cannot be, improved. Sadly, there are new machines manufactured today based on this false premise. Conspicuous evidence of this is seen in many wet-sump oil systems found in pumps, gearing and bearings.
