Abstract
Lubrication systems for high speed spindles characterized by precision cyclical fractional drop injection of liquid lubricant into nozzle directed toward bearings with continuous regulated pressure air stream to deliver accurate quantity of atomized lubricant mist over substantial period of time following each injection.
Claims14
Lubricating system comprising the method steps of cyclically positively displacing accurate liquid lubricant injections through a pressure resisting check valve into a pressurized oil filled delivery tube passage leading through a second pressure resisting check valve at a nozzle directed toward a lubrication target, and continuously supplying air under regulated pressure at less than line pressure at the outlet of said second valve to atomize, entrain, and scour each injection of lubricant from surfaces at second said check valve and nozzle in order to deliver an accurate quantity of atomized lubricant mist over a substantial period of time following each injection of lubricant into the nozzle.
