A bearing lubrication device, an output shaft lubrication device and a process for lubricating an output shaft

摘要

A bearing (131; 132) lubrication system includes a stationary output shaft carrier (150) housed within a gear housing (101) wherein the output shaft (103) resides partially within the carrier and upper and lower bearing (131; 132)s support the shaft. The carrier includes first and second arcuately extending troughs (121; 125) for catching lubricating fluid (201) slung by an oil slinger (141). The first trough (121; 125) is in fluid communication with the shaft and with the upper bearing (131; 132) which pumps fluid (201) through the bearing (131; 132) and into an upper passageway which terminates in an opening which supplies fluid (201) to a second trough (121; 125) which, in turn, supplies fluid (201) to the second bearing (131; 132) which, in turn, supplies fluid (201) to the annular pool formed on the upper portion of the gear affixed to the output shaft (103). 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.
