The invention discloses a water
lubrication thrust bearing wit a ring grooves, relating to a
thrust bearing. The invention solves the problems of bad performance of frictional wear, easy wear and
cracking to a
grinding disc, small bearing area, low
bearing capacity, short service life, difficult fluid hydrodynamic
lubrication, unreliable work process, complicated structure, large axial size, complicated
processing process and high cost and so on of the prior
thrust bearing. A friction surface (1) of the thrust bearing is provided with aequilate water grooves (2) along the radial direction, sector massive bearing surfaces is formed on the friction surface (1), and the sector massive bearing surfaces are provided with ring grooves (3). The water
lubrication thrust bearing with the ring grooves has the advantages of high
bearing capacity, long service life, easy fluid hydrodynamic lubrication, stable and reliable work process, simple structure, small axial size, simple
processing process and low cost and so on. Practical application of the water lubrication thrust bearing with the ring grooves can improve whole device efficiency and reliability of
water environment work machinery to a large extent, which brings better economic benefit and social benefit, and has better development potential and market prospect.
