Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a ball-collecting device for bearings. Background Art

[0002] A relatively complete ball bearing contains five basic components: balls, inner rings, outer rings, retainers and retaining rings; the first step is to prepare the inner and outer rings, with the inner ring placed aside; the second step is to put in the steel balls; the third step is to separate the balls, using a ball separator with small claws to evenly separate the steel balls; the fourth step is to place the retainer and rivet the two retainers together.

[0003] For example, the patent authorization announcement number CN208997206U discloses a single-station ball gathering and separation mechanism for a bearing. Since it does not have the function of further centering the balls after gathering them, the balls are still relatively loose after gathering, which reduces the accuracy of gathering. Therefore, it is urgent to design a ball gathering device for bearings. Utility Model Content
