Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly, in particular to an automatic bearing ball assembly machine. Background Art

[0002] Ball bearings are a type of rolling bearings. Spherical alloy steel balls are installed between the inner and outer steel rings to reduce friction during power transmission and improve the transmission efficiency of mechanical power. Ball bearings mainly consist of four basic components: balls, inner rings, outer rings and cages.

[0003] The cage (i.e., bearing cage, also known as bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and retain them in the bearing. During the assembly process of the bearing, the balls usually need to be assembled on the cage, and the existing assembly between the cage and the balls is usually manual assembly.

[0004] In the above solution, the efficiency of manual assembly is extremely low, which affects the efficiency of bearing assembly. Utility Model Content
