Claim 9:
10. A method for manufacturing the planar high-density ball bearing as claimed in claim 9, comprising:
(S1) providing several groups of winding columns on the mold according to the positions of ball holes; each group of winding columns is arranged in an ellipse; the innermost group of winding columns is denoted by A1, and the groups of winding columns are respectively denoted by A1, A2, . . . , An in the sequence from the innermost group of winding columns to the outermost group of winding columns, where n is an integer greater than or equal to 3;
(S2) First, performing the winding outwardly in the sequence from the group A1 to the group An in a staggered manner: take a side facing the center of the ellipse of any one of the winding columns in the group A1 as the starting column, and the starting point of winding is a point on that column facing the center of the ellipse; from the starting point of winding, the fibers are wound in a fixed circumferential direction of the cage in a staggered manner, and every time the fibers have passed between two columns in the same group, they go to wind the same adjacent group of winding columns in the same way in the same direction, until they come to wind the group An of winding columns where they wind at least two winding columns in the group An by passing by them in a staggered manner;
then performing the winding inwardly in the sequence from the group An to the group A1 in a staggered manner: after passing between the two winding columns of the group An, the fibers go to wind the same adjacent group in the same way in the same direction every time they have passed between two winding columns in the same group, until they come to a side of the winding column in the group A1 facing the center of the ellipse;
(S3) Repeating the winding process in step S2 in the same direction, until the wound article reaches a predetermined thickness;
(S4) Pouring epoxy resin to cure, then demoulding.
