Water lubricating thrust bearing possessing annular groove

Abstract

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.

Description

Water-lubricated thrust bearings with ring grooves technical field The invention relates to a thrust bearing. Background technique At present, the thrust bearing adopts an integral self-aligning straight groove structure, that is, several radially equal-width water grooves are processed on the circular friction surface to form a fan-shaped block-shaped bearing surface. Self-aligning structure with spherical support. This structure is mainly to increase the fluidity of water, improve the cooling effect, reduce the frictional surface and internal temperature of the thrust bearing, and make the load uniform everywhere. In addition, Japan has developed a spiral groove water-lubricated thrust bearing; the invention patent with the announcement number CN1719055 and the announcement date is January 11, 2006 discloses "Spiral groove water-lubricated rubber alloy bearing"; the announcement number is CN1124827, the announcement date is For the invention patent on June 19, 1996, "D...
