ABSTRACT:
A self lubricating industrial vibrator for applications requiring vertical installation. The vibrator comprises a rigid generally cylindrical housing in which an elongated, rotatable shaft is vertically, coaxially received for rotatable displacement by an external conventional motor. Eccentrics secured on opposite ends of the shaft provide vibration, and the shaft is operationally secured for rotation within suitable bearing structure. An oil passageway is thus defined interiorly of the bearing casing, at opposite ends of the internal shaft between upper and lower annular bearing caps. A first lubricating oil reservoir is disposed within the bearing housing in fluid flow communication with a portion of the lower shaft, and the shaft includes an internal, coaxially defined elongated bore which has been internally, spirally grooved. This "rifled" shaft bore or interior draws lubricating oil up and through the shaft and distributes it through the bearings through suitable oiling pathways for continual and reliable self lubrication. Additionally, a rotatable, shaft-driven impeller disposed within a second oil reservoir outside of the bearing housing forces oil upwardly through the shaft bore in cooperation with the rifling, whereby to effectuate oil flow communication between the first and second oil reservoirs.
