1. utilize the method for rolling element filling ball roller bearing, described ball roller bearing (1) mainly by outer bearing ring (2) and inner bearing ring (3) and be arranged in a large number described outer bearing ring (2) and described inner bearing ring (3) between ball roller (4) form, described ball roller (4) has respectively two and from ball basic model body, scabbles symmetrically, the side (5 being set parallel to each other, 6) and by retainer (7) in week, upwards with uniform spacing, keep relative to each other, wherein, described ball roller (4) is in the side (5 of described ball roller (4), 6) between, there is the ball basic model body diameter (d for described ball roller (4) k) 70% width (b k) and the rolling surface (8) that utilizes described ball roller (4) two the channel form raceways (11,12) in being worked into the inner side (9) of described outer bearing ring (2) and the outside (10) of described inner bearing ring (3) in roll, the degree of depth (t of described raceway (11,12) lA, t lI) be the ball basic model body diameter (d of described ball roller (4) k) 20%, and spacing (a between the described inner side (9) of described outer bearing ring (2) and the described outside (10) of described inner bearing ring (3) l) be only the ball basic model body diameter (d of described ball roller (4) k) 60%, it is characterized in that described ball roller (4) through the spacing (a between described outer bearing ring (2) and described inner bearing ring (3) l) carry out axially-tumble-eccentric assembling, described axially-tumble-eccentric assembling in, these two are arranged in described outer bearing ring (2) that keep flat, on concentric position and the described inner bearing ring (3) in described inner bearing ring (3) relative to each other for being greater than the width (b of described ball roller (4) between generation described outer bearing ring (2) and described inner bearing ring (3) k) the spacing (a that forms l), on the one hand can be along bearing longitudinal central axis line (L a) motion a little diametrically, and be arranged on the other hand axially stagger in the plane higher than described outer bearing ring (2), described method has following steps:

  • A) described inner bearing ring (3) is radially passed in eccentric stop dog position, and the described side with described ball roller (4) (5,6) are transported to bearing longitudinal central axis line (L towards the described ball roller (4) of described outer bearing ring (2) and described inner bearing ring (3) orientation a) maximum spacing (a between the above outer bearing ring (2) and described inner bearing ring (3) l) be set to insert on the position of position (13);

    B) on the position of slightly tumbling towards described outer bearing ring (2), by described ball roller (4) follow successively introduce between described outer bearing ring (2) and described inner bearing ring (3) described in insert in position (13), until remaining empty charge space (14) is only also equivalent to the ball basic model body diameter (d of single ball roller (4) between described outer bearing ring (2) and described inner bearing ring (3) k);

    C) axially fall described inner bearing ring (3) and axially promote described outer bearing ring (2) simultaneously in following position, in described position, described outer bearing ring (2) and described inner bearing ring (3) are arranged in a common plane and by the described ball roller (4) in the described raceway (11,12) of tumble described outer bearing ring (2) and described inner bearing ring (3) and are clamped between described raceway (11,12);

    D) described outer bearing ring (2) Spin-up is arrived to following rotating speed, under described rotating speed, described ball roller (4) is by spinning and by centrifugal force, be independently orientated and occupied the inner position evenly tilting of described raceway (11,12) of described outer bearing ring (2) and described inner bearing ring (3);

    E) stop described outer bearing ring (2) and simultaneously axially fall described inner bearing ring (3) and described outer bearing ring (2), until described ball roller (4) is arranged on the neat position of the interior level of described raceway (11,12) of described outer bearing ring (2) and described inner bearing ring (3);

    F) inserted described ball roller (4) is evenly distributed in the cyclotomy of described ball roller bearing (1), and described retainer (7) is passed to the spacing (a between described outer bearing ring (2) and described inner bearing ring (3) l) pack into, finally described ball roller bearing (1) is applied to grease and sealing.
