The Jinshi thrust bearing is a laminated active balance thrust bearing; it is composed of several thrust blocks. The thrust block underlay has an upper level block, a lower level block, and a base ring; the equivalent of a 3-layer part is stacked on the base ring. The thrust block and the level block are touched by the spherical fulcrum.
The working principle: when the load of each thrust block is not together; it will lead to the imbalance of the bearing; the thrust block will be deflected due to uneven force; at this moment, the level block can be connected through the upper and lower parts; Push the load on the block; until the load on each thrust block is the same; the bearing is balanced from the head to stop. That is, when the rotating shaft has large deflection and fulcrum angle; the orientation of each tile can be balanced and uniform Oil film pressure.
The typical layout of the Jin's thrust bearing: its main body consists of the tile, the horizontal block that swings up and down, the carrier plate and the oil control ring. The lubricating oil enters the bearing cavity from the bottom notch of the carrier plate; the air and the thrust between the tiles The disc rotates into the bearing surface of the thrust pad; and the oil is brought to the outer circumference by centrifugal force; and then the oil drain hole in the upper part of the oil control ring flows out to the outside of the bearing body.
