Abstract
A fuel lubricated anti-friction bearing comprises an inner race for an anti-friction bearing having a plurality of radially opening apertures communicating with a fuel supply, a rotatable outer race, and a plurality of anti-friction rollers between the inner and outer races, rotation of the outer race effecting rotation of the rollers and pumping of fuel radially outwardly through the apertures in the inner race of the rollers.
Claims6
A fuel lubricated anti-friction bearing comprising:
- a fuel inlet manifold;
- a cylindrical inner race for an anti friction bearing supported by said manifold having a plurality of radially opening apertures communicating with said manifold in fluid flow relation;
- a hollow engine shaft;
- an outer race on said engine shaft;
- and
- a plurality of anti friction rollers between said inner and outer races, rotation of said engine shaft effecting rotation of said rollers and pumping of fuel radially outwardly of said fuel inlet manifold through the apertures in the inner race of said bearing to the rollers thereof.
