Abstract
A reversible vertical journal bearing with a self contained closed circuit lubrication system, directed toward ceiling fan applications, is disclosed. Lubricant pumping, from a reservoir, is accomplished by an array of throttled, high pressure, triangular pumping cavities on the journal surface. The array is completely symmetrical about the journal axis, so that unidirectional lubricant flow is produced at either direction of journal rotation. The lubricant is collected in a manifold at the top of the bearing, and it is gravity fed back into the reservoir. Optimum design parameters for a stable high load bearing capability device are indicated.
