‘Directed Lubrication’ Thrust Bearings
In tilt pad thrust bearings, ‘Direction Lubrication’ can significantly reduce power loss and oil flow, particularly at high speeds, by eliminating churning of the oil within the casing that results in high power loss in flooded lubrication systems. The thrust bearing housing must be kept free of bulk oil by ample drain area around the collar periphery. No shaft seals are required, thus also simplifying installation.
Our ‘Directed Lubrication’ has oil jets, which impinge on the trailing edge of the proceeding pad to help reduce local high temperatures, scour hot oil from the collar as well as spray fresh oil to the inlet edge of each pad. By reducing hot oil carryover, Waukesha’s ‘Directed Lubrication’ reduces pad temperatures and also increases film thickness, permitting higher specific loading. This allows the use of a smaller bearing to support a given load, leading to further saving in power due to a reduced bearing diameter.
