Static Feed Oil Wick System

Lubrication for ball bearings which journal an element, adapted to be rotated at very high speeds on a stationary support, is provided by a static feed oil wick system.

To lubricate the ball bearings 2, oil is supplied to the lubricant retaining chamber 3 by means of an oil saturated wick 4. A portion of the wick 4 is within a tube 6, and in fluid communication with the bottom portion of an oil reservoir 7. The reservoir is provided with a sight glass 8 for observance of a predetermined level of the oil. Oil is added or drained from reservoir 7 through the fill and drain plugs 9 and 10, respectively. One end of tube 6 is threaded into the end of the stationary shaft 5 and engages a bore 12. This communicates with a radial bore 14 extending to the outer periphery of the stationary shaft 5. Mounted to this is a control tube 15 which extends into the chamber 3 and whose outer open end faces against the direction of rotation. The wick 4 extends the length of the bores 12 and 14 and contacts with the control tube 15.

The purpose of the control tube 15 is significant in that it is directed against rotation so that the fluid pressure created by rotation acts upon the wick 4 to prevent further flow of oil into the chamber 3. The tube also scoops excess oil, which exists upon high speed rotation, from the ring 16. After removing the predetermined excess of oil the control tube 15 then just contacts the inner periphery of the ring of oil 16 to d...
