ABSTRACT:
A vibratory apparatus comprises an eccentric mass disposed within a housing. A shaft and bushing are received by the eccentric mass and couple the eccentric mass to a crankshaft. An internal conduit extends longitudinally within the shaft. Input and output conduits each communicate with the internal conduit to allow a lubricant to flow through the shaft. A bore extends radially through the bushing. Lubricant flowing through the shaft may further flow through the bore and form a lubricating layer between the bushing and the eccentric mass.
