Figure B-2. Single reduction high speed gear unit (cutaway view) with
double helical gearing and a simple pressurized lubrication system. The
gear housing acts as the lubricant reservoir, and a shaft-driven oil pump
pressurizes the oil. The high and low speed shafts are supported by bab-
bitted journal bearings, and any thrust loads are handled by babbitt-faced
thrust bearings on the low speed shaft.
