Description

Technical Field

[0001] The utility model belongs to the field of bearings, and in particular relates to a bearing which is easy to replace. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy.

[0003] When installing balls on the bearing, it is usually necessary to manually knock the last few balls to completely install the bearing. Such excessive squeezing will cause certain damage to both the bearing and the balls, thus affecting the subsequent use of the bearing. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a bearing which is easy to replace.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a bearing that is easy to replace, comprising an outer ring and an inner ring, a plurality of balls are arranged between the outer ring and the inner ring, and the balls are evenly distributed through a retaining frame, characterized in that at least two disassembly and assembly components are arranged in the inner ring;

[0006] The disassembly and assembly component comprises a filling block, both sides of which are arranged with inclined surfaces, and two abutment balls are movably arranged in the filling block.

[0007] Optionally, at least two notches are formed on the inner wall of the inner ring, the cross-section of the notches is trapezoidal, and the filling blocks are exactly installed in the notches.

[0008] Optionally, an arc-shaped groove is provided on an end face of the filling block away from the center line of the outer ring, which is consistent with the outer peripheral side of the inner ring, and the cross-section of the filling block is trapezoidal.

[0009] Optionally, an abutment groove is provided at the bottom of the filling block, and the end surfaces on both sides of the bottom of the abutment groove are inclined surfaces, and the abutment ball is located in the abutment groove.

[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Due to the setting of the disassembly and assembly components, the filling block can be removed and the ball bearings can be filled and installed through the gap. The gap can make the disassembly and assembly of the ball bearings extremely simple and convenient, and the ball bearings are not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0017] As shown in Figures 1-3, a bearing that is easy to replace includes an outer ring 10 and an inner ring 11. A plurality of balls 13 are arranged between the outer ring 10 and the inner ring 11. The balls 13 are evenly distributed through a retaining frame 12. At least two disassembly and assembly components are arranged in the inner ring 11. The disassembly and assembly components include a filling block 14. The two sides of the filling block 14 are arranged with inclined surfaces. Two abutment balls 15 are also movably arranged in the filling block 14. At least two notches are opened on the inner wall of the inner ring 11. The cross-section of the notch is set in a trapezoidal shape. The filling block 14 is just installed in the notch. The end face of the filling block 14 on one side away from the center line of the outer ring 10 is provided with an arc-shaped groove, which is consistent with the outer peripheral side of the inner ring 11. The cross-section of the filling block 14 is set in a trapezoidal shape. An abutment groove 16 is opened at the bottom of the filling block 14. The end faces on both sides of the bottom of the abutment groove 16 are inclined surfaces, and the abutment balls 15 are located in the abutment groove 16.

[0018] During use, when adding balls 13 between the outer ring 10 and the inner ring 11, first add a small amount of balls 13, then distribute them evenly, then remove the filling block 14, and fill the balls 13 between the outer ring 10 and the inner ring 11 through the gap until the balls 13 are completely filled, then install the retaining frame 12, and then install the filling block 14, and then the bearing can be mounted on the shaft. When the shaft rotates to drive the inner ring 11 to rotate, the abutment ball 15 will be stuck on the shaft through the setting of the inner bevel of the abutment groove 16. The faster the shaft rotates, the tighter the abutment ball 15 is stuck, effectively preventing the bearing from detaching.

[0019] When the bearing needs to be disassembled, the bearing is knocked axially to disengage the bearing, and then the filling block 14 is removed to remove the ball 13 from the notch. This removal method is simple and convenient, and the ball 13 is not easily damaged.

[0020] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
