BEARING COOLING SYSTEM FOR VIBRATORY DEVICES

摘要

An bearing cooling system is connected to and actuated by the vibration of a vibratory device to pump lubricant to lubricate internal components of the vibratory device. The bearing cooling system has a bottom end cap with an inlet in fluid communication with the vibratory device, a top end cap with an outlet for delivering the lubricant to lubricate components of the vibratory device, a tube disposed between and sealingly engaging the bottom end cap and the top end cap, and a piston having a lubricant passageway. The piston is slidably disposed within the tube downstream of the bottom end cap and upstream of the top end cap. Vibration of the vibration device causes the piston to oscillate within the tube to draw lubricant from the vibration device which passes through the lubricant passageway in the piston, and delivers lubricant to lubricate internal components of the vibration device. Upstream of the top end cap a heat exchanger and/or a filter can be used to cool and/or remove debris from the lubricant before lubricating the internal components.

主权项

1. A vibratory assembly for containing lubricant and comprising:
an exciter having a housing with an interior having a reservoir portion for receiving the lubricant in a lubricant reservoir and internal components, the internal components comprising bearings and at least a first eccentric weight rotatable in a clockwise direction and a second eccentric weight rotatable in a counter-clockwise direction, rotation of the first eccentric weight and the second eccentric weight causing vibration of the housing; and a cooling system comprising a heat exchanging assembly, a fluid, and a fluid pump, the heat exchanging assembly having at least one surface being exposed to the interior of the housing and the lubricant contained within the interior of the housing and a tortuous pathway not exposed to the interior of the housing, the tortuous pathway being a portion of a closed loop conduit through which the fluid flows under the force of the fluid pump.
