Abstract
A planar high-density ball bearing comprises a cage and balls; the cage is provided with multiple groups of ball holes for arranging the balls; the ball holes in each group are distributed in the circumferential direction of the cage in an ellipse; the centers of the ellipses in each of which a group of ball holes is distributed coincide with each other, the major axes of the ellipses lie in a common line. The ball holes in adjacent groups are arranged to be staggered in relative to each other in the circumferential direction of the cage, and the balls in the same group of the ball holes are distributed in an ellipse. A method for manufacturing the planar high-density ball bearing, nutation reducer are provided.
