Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a radial tensioning device used for processing deep groove ball bearings. Background Art

[0002] Existing radial tensioning devices used for deep groove ball bearing processing are inconvenient to tighten, hindering flexible control of the tensioning force and rapid bearing processing. The bearings are prone to slight deviations during the tightening process, and the device lacks stability. A Chinese patent application, numbered "CN202121660071.6," discloses a "radial tensioning device for deep groove ball bearing processing." The device features a support frame fixedly connected to the top right side of a base plate, a mounting plate fixedly connected to the top of the support frame, an inflation mechanism fixedly connected to the top of the mounting plate, a tensioning mechanism fixedly connected to the left side of the inflation mechanism, a mounting frame fixedly connected to the top left side of the base plate, and a placement plate fixedly connected to the top of the mounting frame. This radial tensioning device for deep groove ball bearing processing, when the outer ring of the deep groove ball bearing needs to be tightened, is fitted with a tensioning plate on the inner ring of the outer ring. At this time, the airbag expands, allowing the movable bar to slide evenly on the sliding rod, thereby causing the tensioning plate to expand in all directions to tighten the outer ring. This tightening effect is achieved through a simple mechanical structure, effectively solving the problem of existing outer ring tensioning operations being cumbersome and inconvenient for subsequent maintenance and replacement. However, the device's operating procedures are complex, and the adjustment process is inconvenient, which is not conducive to flexible control of the tensioning force and is not conducive to rapid processing. The bearing offset caused by the device can lead to instability in the bearing processing process, and the device lacks stability. Utility Model Content
