System and Method to Prevent Premature Wear on Key Shaft

摘要

A system and method for lubricating a key shaft in a compaction machine is disclosed. The compaction machine may include a spline oil cavity and a key shaft in fluid communication with the spline oil cavity. The key shaft may include an axial splined portion and a helical splined portion on an outer surface thereof, a longitudinal lubricating passage extending through a substantial length of the key shaft and a plurality of additional lubricating passages intersecting the longitudinal lubricating passage. The system and method may additionally include lubricating the axial splined portion and the helical splined portion of the key shaft with the lubricating oil drawn from the spline oil cavity.
