Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a plane thrust ball bearing comprises a shaft ring 1, a first sliding groove 2 is formed in the lower surface of the shaft ring 1, a first retainer 5 is arranged below the shaft ring 1, an oil storage groove 12 is formed in the inner side of the outer wall of the first retainer 5, an oil guide groove 9 is formed in the inner side of the inner wall of the first retainer 5, a groove 11 is formed in the lower surface of the first retainer 5, a second retainer 6 is arranged at the bottom end of the first retainer 5, an extension 10 is welded on the upper surface of the second retainer 6, a fixing hook 8 is welded on the left side of the extension 10, the fixing hook 8 and the oil storage groove 12 form a buckle structure, the extension 10 is inserted into the groove 11, the second retainer 6 is connected with the first retainer 5 through the extension 10, steel balls 7 are annularly and equidistantly arranged, the steel balls 7 and the second retainer 6 form a rotating structure, the extension 10 and the oil storage groove 11 are inserted into each other, and the top end of the fixing, the first retainer 5 and the second retainer 6 can be connected and fixed.

The steel ball 7 is embedded in the inner side of the second retainer 6, the top end of the steel ball 7 is attached to the inner wall of the first sliding groove 2, the steel ball 7 and the first sliding groove 2 form a rotating structure, the top end of the steel ball 7 is embedded in the first sliding groove 2, and the first sliding groove 2 can guide the movement track of the steel ball 7.
