Scavenging pump

摘要

A scavenging gear pump for use in a final drive comprising a drive gear and a driven gear, each being mounted for rotation and in mesh with each other. The drive gear is coupled with an input shaft and rotated thereby and has formed therein a fluid passage for communicating an outlet port of the pump with a fluid chamber formed in the input shaft. A plurality of guide passages are formed in the input shaft for supplying lubricant from the fluid chamber to rotary components, such as bearings and gears.
