Technical Field

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

[0002] Bearings are an important component in mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings. Existing bearings are very inconvenient to disassemble and assemble, which causes damage to the local ball bearing structure and makes the entire bearing unusable. It is also difficult to maintain and replace the local part. Therefore, a bearing that is easy to install is proposed to address the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a bearing that is easy to install in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a bearing that is easy to install, including an outer ring, a short tube, balls, a limiting ring seat, a circular groove and a magnet, balls are distributed in a ring between the middle of the annular surface of the short tube and the inner ring wall of the outer ring, and two limiting ring seats are symmetrically threaded on the short tube, the inner wall of the annular guide space formed between the two limiting ring seats is in rolling contact with the balls, and magnets are installed in the circular grooves distributed on the limiting ring seat.

[0005] Preferably, the circular grooves are not limited to a group of twelve, and the circular grooves are distributed in an annular manner and are opened on the annular surface of one side of the limiting ring seat.

[0006] Preferably, the magnet and another magnet in a circular groove on the same midline are in a state of mutual magnetic attraction.

[0007] Preferably, the ball and the annular surface of the short tube are always in a non-contact state.

[0008] Preferably, the inner ring wall of the limiting ring seat and the surfaces on both sides of the middle part of the short tube are provided with threaded structures.

[0009] Compared with the prior art, the advantages of the utility model are: the method of placing two limit ring seats that can be detachably connected by threads on the short tube is conducive to forming an annular limit space for placing the ball, and the disassembly and maintenance are convenient, which greatly reduces the gap between the ball and the inner wall of the outer ring, enhances the stability of the bearing rotation operation, and prevents the threaded connection between the limit ring seat and the short tube from loosening by magnetically attracting another magnet on the same center line with one-to-one distribution. The anti-loosening binding force is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] See also Figure 1-3 As shown, a bearing that is easy to install includes an outer ring 1, a short tube 2, balls 3, a limiting ring seat 4, a circular groove 41 and a magnet 5. The balls 3 are distributed in an annular manner between the middle of the annular surface of the short tube 2 and the inner ring wall of the outer ring, and two limiting ring seats 4 are symmetrically threadedly connected on the short tube 2. The inner wall of the annular guide space formed between the two limiting ring seats 4 is in rolling contact with the balls 3, and the magnets 5 are installed in the circular grooves 41 distributed on the limiting ring seats 4.

[0019] Furthermore, the circular grooves 41 are not limited to being a group of twelve, and the circular grooves 41 are distributed in an annular manner and are opened on the annular surface of one side of the limiting ring seat 4 .

[0020] Furthermore, the magnet 5 and another magnet 5 located in the circular groove 41 on the same midline are in a state of mutual magnetic attraction.

[0021] Furthermore, the ball 3 and the annular surface of the short tube 2 are always in a non-contact state.

[0022] Furthermore, the inner ring wall of the limiting ring seat 4 and the surfaces on both sides of the middle part of the short tube 2 are provided with thread structures.

[0023] When the utility model is in use, two limit ring seats 4 that can be detachably connected by threads are placed on the short tube 2, which is conducive to forming an annular limit space for placing the ball 3. The disassembly and maintenance are convenient, and the gap between the ball 3 and the inner wall of the outer ring member 1 is greatly reduced, thereby enhancing the stability of the bearing rotation operation. The magnets 5 distributed one by one and another magnet 5 on the same center line are in a magnetic attraction state, thereby preventing the threaded connection between the limit ring seat 4 and the short tube 2 from loosening, thereby increasing the anti-loosening binding force.
