Abstract
A cooling and lubrication arrangement for a bearing supporting a rotatable shaft wherein the bearing housing includes, a self contained lubrication system for the bearing, and an operatively associated improved cooling fluid flow chamber therein. The bearing housing has supporting structure to minimize conductive heat flow to the bearing and the improved cooling fluid flow chamber has one relatively thin supporting wall adjacent the bearing and is provided with an internal geometry which forms a zone of high velocity cooling fluid closely adjacent the said thin supporting wall to achieve a high heat transfer rate from the bearing to the cooling fluid flowing through the improved cooling fluid flow chamber. A conventional open or closed type cooling fluid circulating system is connected to the bearing housing for delivering cooling fluid to and removing the same from the cooling fluid flow chamber and such fluid circulating system may desirably include an auxiliary circulating device for use on hot standby condition or after shut down of the apparatus or equipment such as a turbine with which the bearing is operatively associated. Additionally the cooling and lubrication arrangement…
