Summary for Patent: 5,503,407
Title: Windbacks for rotating shafts
Abstract:An annular windback is provided in a housing containing a lubricant sump and a rotating shaft therein. The windback is located at one end of the sump and the shaft extends through the windback. The housing has a seal interacting between the housing and the shaft to prevent lubricant from exiting the sump and to prevent other media within the housing from entering the sump. The windback is located between the seal and the one end of the sump and has a spiral groove in the inner annular surface facing the shaft for providing a return path for lubricant carried toward the seal by shaft windage. One or more radial holes are formed in the windback at an axial location thereon between the seal and the closer end of the spiral groove to equalize the pressure at the aforesaid axial location between the windback and the shaft with the pressure in the remainder of the sump.
