Anchor is fluid bearing change

The utility model provides an anchor is fluid bearing change which it includes characterized in that lower eye end cover, barrel, slide bearing, thrust bearing, goes up the eye end cover, the eye end cover has a long pivot down, and barrel, slide bearing, thrust bearing install in long pivot according to the preface, and the axle head compresses tightly through compressing tightly the piece, and lower eye end cover can rotate with the barrel relatively, barrel and last eye end cover fixed connection. The superiority: the utility model discloses a two sections anchors are connected respectively to the eye of upper and lower eye end cover is the structure, when upper and lower two sections anchors be structure when having torsion load, upper and lower eye end cover can rotate relatively, sheds torsion load, the utility model discloses the inside oil that is full of of barrel to sealed through oil blanket, barrel sealing washer, oil filler point sealing washer, oil does not leak, and the bearing sufficient lubrication had both been guaranteed in not endosmose of water, makes again the utility model is used for inside and outside pressure differential almost is zero in the time of under water, has avoided outer compressive strain.
