This utility model discloses an automatic centering ball-distributing oscillator structure, belonging to the field of bearing assembly. The automatic centering ball-distributing oscillator structure includes an upper connecting seat, with a lower connecting seat at the bottom of the upper connecting seat. The upper and lower connecting seats are interconnected by a centering structure. This utility model solves the problems of traditional oscillating ball-distributing mechanisms, where a single soft rubber body directly connects to the ball distributor for rotational oscillation, or directly connects to an object for rotational oscillation. These mechanisms are prone to breakage of the connecting rubber body, resulting in a short service life, frequent replacement of parts, low production efficiency, and increased operating costs. More critically, when using a single soft rubber body structure, the concentricity of the oscillating component is poor, preventing automatic centering. When used in bearing production equipment, the poor concentricity of the oscillating component frequently causes it to bump against the bearing edge. This utility model patent solves all these problems, resulting in significant economic benefits.
