Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, in particular to a bearing ball screening device. Background Art

[0002] Bearings are an important component in modern mechanical equipment. They are mainly composed of inner rings, outer rings and rolling elements. Bearings rotate at high speeds when working, and the pressure of the inner and outer rings mainly acts on the rolling elements. Common rolling elements include balls and cylindrical rollers. The size of the balls determines the stability of the bearing during use.

[0003] In the process of ball production, balls of different sizes are produced. Therefore, when the balls are assembled on the inner and outer rings of the bearing, a bearing ball screening device is required to screen the balls. However, in the existing technology, most bearing ball screening devices can only gradually screen balls of different diameters into areas of different diameters, but it is difficult to screen balls of different diameters into areas of different diameters at the same time, thereby reducing the ball screening efficiency. For example, a ball screening device for bearing production provided by the Chinese utility model patent with announcement number CN216936914U includes a screening tank, a sieve plate is provided inside the screening tank, and the The upper surface of the sieve plate is provided with a through hole for allowing the bearing balls to pass through. A top cover is detachably installed at the upper opening of the screening tank. A support portion is provided downward at the center of the bottom of the top cover. The lower end of the support portion is rotatably connected to a stirring assembly. A driving source for driving the sieve plate to rotate is provided at the bottom of the sieve plate. When the bearing balls with a larger diameter stay on the sieve plate, when a part of the bearing balls with a diameter slightly larger than the sieve hole enters the upper end of the sieve hole and the other part is exposed, the bearing balls interfere with the stirring assembly, and the stirring assembly can rotate together with the sieve plate, effectively avoiding damage to the stirring assembly and the bearing balls stuck in the upper end of the sieve hole.

[0004] Although the above device can screen balls of different diameters, it can only gradually screen balls of different diameters into areas of different diameters, and it is difficult to screen balls of different diameters into areas of different diameters at the same time, thereby reducing the screening efficiency of the balls.
