ABSTRACT:
A vibratory mechanism includes apparatus adapted for vibratory actuation to perform a predetermined function. A tubular housing is connected to the apparatus at spaced points, and a pair of hydrodynamic bearings are mounted in the housing at points located outwardly from the points of connection of the housing to the apparatus. A shaft is rotatably supported in the hydrodynamic bearings, and structure is provided for continuously directing oil to the hydrodynamic bearings and to thrust bearings which position the shaft axially. Oil from the bearings is directed to drain structure comprising part of the tubular housing. Eccentric weights are mounted on the shaft for rotation therewith and are positioned at points located outwardly from the hydrodynamic bearings. The shaft and the housing have matched deflection characteristics under loads imposed by the rotating eccentric weights so that the hydrodynamic bearings and the portions of the shaft extending therethrough are continuously maintained in precise alignment.
