However, the installation of the cage also needs to be attached between the inner and outer rings of the bearing, and will also generate a certain amount of friction. Utility Model Content

[0003] The utility model aims to provide a device for protecting a deep groove ball bearing from wear, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A device for protecting deep groove ball bearings from wear, comprising a bearing inner ring, a bearing outer ring, a rolling element reserved cavity, rolling elements, an arcuate cage, a cage fixing reserved hole, a rolling element reserved cavity sealing cover, a rotating ring, and a cage fixing screw. A rolling element reserved cavity is reserved between the bearing inner ring and the bearing outer ring, a plurality of rolling elements are equidistantly installed in the rolling element reserved cavity, and an arcuate cage is installed on both sides of each rolling element. The arcuate cage can install and fix the rolling elements at the same interval to reduce friction between each other, the front and rear ends of the arcuate cage are provided with cage fixing reserved holes, the front and rear ends of the rolling element reserved cavity are provided with rolling element reserved cavity sealing covers, a rotating ring is installed in the rolling element reserved cavity sealing cover, and cage fixing screws matching the number of cage fixing reserved holes are equidistantly installed on the rotating ring.

[0006] Preferably, the anti-wear device for protecting the deep groove ball bearing also includes a lubricating oil sealing cover, and a lubricating oil sealing cover is installed on the front side of the rolling element reserved cavity sealing cover to facilitate adding lubricating oil that reduces friction into the rolling element reserved cavity.

[0007] The beneficial effects of the utility model are as follows: the utility model has a reasonable design, the internal rolling elements and the retaining frame are fixed by the front and rear sealing covers, so that the rolling elements in the rolling element reserved cavity will not be connected to each other, reducing friction, and at the same time the retaining frames are suspended in the reserved cavity to avoid friction between the retaining frames and the inner and outer rings. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The utility model is a schematic diagram of the structure of the device for protecting deep groove ball bearings from wear.

[0009] In the figure: 1. bearing inner ring, 2. bearing outer ring, 3. rolling element reserved cavity, 4. rolling element, 5. arc-shaped retaining rack, 6. retaining rack fixing reserved hole, 7. rolling element reserved cavity sealing cover, 8. rotating ring, 9. retaining rack fixing screw, 10. lubricating oil sealing cover. DETAILED DESCRIPTION

[0010] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0011] like Figure 1 As shown, a device for protecting deep groove ball bearings from wear is provided, comprising a bearing inner ring 1, a bearing outer ring 2, a rolling element reserved cavity 3, rolling elements 4, an arcuate retainer 5, a retainer fixing reserved hole 6, a rolling element reserved cavity sealing cover 7, a rotating ring 8, and a retainer fixing screw 9. A rolling element reserved cavity 3 is reserved between the bearing inner ring 1 and the bearing outer ring 2. A plurality of rolling elements 4 are equidistantly installed in the rolling element reserved cavity 3, and an arcuate retainer 5 is installed on both sides of each rolling element 4. The arcuate retainer 5 can install and fix the rolling elements 4 at the same interval to reduce friction between each other. Retainer fixing reserved holes 6 are provided at both ends of the arcuate retainer 5, rolling element reserved cavity sealing covers 7 are installed at both ends of the rolling element reserved cavity 3, rotating rings 8 are installed in the rolling element reserved cavity sealing covers 7, and retainer fixing screws 9 matching the number of retainer fixing reserved holes 6 are equidistantly installed on the rotating ring 8. The anti-wear device for protecting deep groove ball bearings also includes a lubricating oil sealing cover 10. The lubricating oil sealing cover 10 is installed on the front side of the rolling element reserved cavity sealing cover 7 to facilitate adding lubricating oil that reduces friction into the rolling element reserved cavity 3.

[0012] The use method of the utility model is as follows: by installing the arc-shaped retaining frame 5 on the rotating changer 8 on the front and rear rolling element reserved cavity sealing covers 7, the arc-shaped retaining frame 5 does not need to be connected with the bearing inner ring 1 and the bearing outer ring 2 when fixing the rolling element 4, thereby avoiding the friction between the retaining frame and the bearing. At the same time, due to the addition of the rolling element reserved cavity sealing cover 7, the lubricating oil that reduces friction can be added to the rolling element reserved cavity 3 through the lubricating oil sealing cover 10.

[0013] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary, and equivalent changes within the equivalent scope are included in the scope of the present invention.
