Patent attributes
An annular seal plate for a shaft assembly in which the seal plate is disposed between and abuts a first adjacent element that rotates with the shaft and seal plate and a second adjacent element that does not rotate with the shaft. The annular seal plate includes an axial scoop defining an annular lubricant collection area disposed radially outwardly from an oil supply orifice that is in fluid communication with a source of pressurized lubricant supplied through the first adjacent element. Lubricant flows through the oil supply orifice and collects in the collection area. An oil passage places the collection area in fluid communication with a lateral surface facing and abutting the second adjacent element to provide lubricant to the interface between the annular seal plate and the second adjacent element.
