Thrust bearing lubricator for rotary shaft machine - has sleeve with two bearings, and includes lubricant distributors and piston valve

摘要

The thrust bearing lubricator is for a machine with a rotary shaft possessing a rotary thrust sleeve. It consists of a first and second thrust bearing (35,37) on each side of the sleeve. The lubricant is distributed to the two thrust bearings (35,37) in relation to the direction of axial thrust by means of distributors (41) with piston valve, first and second pilot fluid holes between which moves a double-sided piston. USE/ADVANTAGE - The required flow of lubricant is kept low whether or not the thrust bearings are the same size or not.
