Sleeve Bearings and Lubricants for Advanced Airframes.
Abstract
Sleeve bearing materials and lubricants were tested on an hydraulically operated apparatus, which simulated the loads and motions of typical airframe bearings. Beryllium-copper alloy 25 provided excellent bearing properties for grease-lubricated applications requiring high stresses and low wear rates. Hardened M-50 tool steel shafts provided excellent wear and fatigue resistance for use with beryllium-copper bearings. The lubricating capabilities of MIL-G-81322 grease were similar to MIL-G-3287 grease, which it replaced, but provided improved resistance to galling. No beneficial effect resulted from the presence of MoS2 in greases used to lubricate molybdenum-containing bearings. (Author)
