ABSTRACT:
A bearing lubrication system includes a stationary output shaft carrier housed within a gear housing wherein the output shaft resides partially within the carrier and upper and lower bearings support the shaft. The carrier includes first and second arcuately extending troughs for catching lubricating fluid slung by an oil slinger. The first trough is in fluid communication with the shaft and with the upper bearing which pumps fluid through the bearing and into an upper passageway which terminates in an opening which supplies fluid to a second trough which, in turn, supplies fluid to the second bearing which, in turn, supplies fluid to the annular pool formed on the upper portion of the gear affixed to the output shaft. The annular pool is formed by a cylindrically shaped dike secured to the upper portion of the gear. Overflow from the pool lubricates the gear and returns oil to the reservoir.
