Claims (1)

[Scope of Claim for Utility Model Registration] (1) A rolling element assembly device that incorporates rolling elements into the inner periphery of a bearing outer ring, comprising an outer ring seating base for positioning and seating the outer ring, and an outer ring seating base above the outer ring seating base. The outer ring seat includes a rolling element supply mechanism disposed so as to be rotatable with respect to each other, and a rotational drive means for rotating at least one of the outer ring seat and the rolling element supply mechanism, The moving element supply mechanism includes a rolling element storage section which is provided in the vertical direction and accommodates a predetermined number of rolling elements, and has an opening toward the inner circumference of the bearing outer ring on the outside of the bottom; an eccentric cam which is provided to push one rolling element in the rolling element storage part into the inner periphery of the outer ring from the opening in sequence for each rotation, and a rotational drive means for rotating the eccentric cam. A bearing fitting mechanism characterized by: (2) A rolling element assembly device that assembles rolling elements onto the inner periphery of a bearing outer ring, which comprises: an outer ring seating for positioning and fixing the bearing outer ring; and a hole provided in the center of the outer ring seating in a vertical direction. a rotating drive shaft having a connecting portion at its upper end and connected to a drive source at its lower end; a rolling element supply mechanism disposed above the outer ring seating so as to be rotatable relative to the outer ring seating; It is constituted by a rotational drive means for rotating at least one of the rolling element supply mechanism and the outer ring seating, and a lifting means provided on at least one of the rolling element supplying mechanism and the outer ring seating for moving the rolling element supply mechanism and the outer ring seating toward and away from each other. The moving element supply mechanism includes a rolling element storage section that stores the rolling elements in a vertically connected manner inside and has an opening on the outside of the bottom that allows the rolling elements to escape, and a rolling element storage section that fits loosely into the opening and that rotates each rotation. Equipped with an eccentric cam that sequentially pushes the rolling elements from the opening into the inner circumference of the outer ring of the bearing, and a rotation shaft that is provided vertically at the center of rotation of the eccentric cam and has a connecting portion at the lower end to rotate the eccentric cam. A bearing fitting mechanism characterized by:
