1. Lubrication System with Tolerance for Reduced Gravity

Author

Subjects
Mechanical Engineering, Aircraft Propulsion And Power
Abstract

A lubrication system includes an auxiliary lubricant tank 48, a supply conduit 58 extending from a source of lubricant 26 to the auxiliary lubricant tank. A reduced-G bypass line 108 branches from the conduit and enters the auxiliary tank at a first elevation E.sub.1. The system also includes an auxiliary tank discharge conduit 116, a portion of which resides within the tank. The resident portion has an opening 122 at least partially at a second elevation E.sub.2 higher than the first elevation.

Abstract

High speed experimental tests provided data on six parametric cylindrical roller bearings. Four bearing variables were evaluated and the results were correlated with the analytical model developed under Naval Air Propulsion Center Contract N00140-76-C-0383 with support form the Air Force Aero Propulsion Laboratory MIPRFY14557600623. Roller end clearance was found to have a significant effect on roller end and guide flange wear, whereas the variables roller end circular runout and inner ring guide flange height were both observed to have a moderate effect on water.
