[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a bearing ring that is easy to assemble, including: a seat ring 1;

[0029] A cage 3 is installed between the bearing seat 1 and the bearing shaft 2. The bearing seat 1 and the bearing shaft 2 support the cage 3 and the rollers 4. Ten rollers 4 are rolled on the cage 3 to reduce the friction when the bearing rotates. An inner mounting sleeve 5 is rotatably installed inside the bearing seat 1 and the bearing shaft 2. The inner mounting sleeve 5 is used to assemble the inner sides of the bearing seat 1 and the bearing shaft 2. A first outer fixing shell 6 and a second outer fixing shell 7 are installed on the outer side of the bearing shaft 2. The first outer fixing shell 6 and the second outer fixing shell 7 cooperate with the inner mounting sleeve 5 to assemble the bearing seat 1 and the bearing shaft 2 together.

[0030] In this embodiment of the disclosure, such as Figures 3-6 As shown, several rubber protrusions are fixed on the outer side of the shaft ring 2. After the first outer fixing shell 6 and the second outer fixing shell 7 are installed, their inner walls will be in close contact with the rubber protrusions on the outer side of the shaft ring 2. During use, the thicker part above the shaft will be in close contact with the top surface of the inner mounting cylinder 5, the first outer fixing shell 6 and the second outer fixing shell 7. Since the first outer fixing shell 6 and the second outer fixing shell 7 are fixed on the outer side of the shaft ring 2 after installation, and the rubber protrusions on the outer side of the shaft ring 2 can also increase the friction, it is ensured that the inner mounting cylinder 5, the first outer fixing shell 6 and the second outer fixing shell 7 can rotate synchronously with the shaft ring 2.

[0031] In this embodiment of the disclosure, such as Figures 2-6 As shown, the upper part of the inner mounting cylinder 5 is a cylinder, and the lower part is an annular plate. The bottom of the seat ring 1 is provided with an annular groove corresponding to the annular plate of the lower part of the inner mounting cylinder 5. The cylinder above the inner mounting cylinder 5 can rotate in the circular hole in the middle of the seat ring 1, and the annular plate below the inner mounting cylinder 5 can limit its movement. Moreover, during installation, the annular plate below it can also be hidden in the annular groove at the bottom of the seat ring 1.

[0032] In this embodiment of the disclosure, such as Figure 1 and Figure 4As shown, after the inner mounting cylinder 5, the first outer fixing shell 6, and the second outer fixing shell 7 are assembled, their top surfaces will all be on the same plane. The bottom surface of the inner mounting cylinder 5 will be above the bottom surface of the seat ring 1. During use, the thicker part above the rotating shaft will be in close contact with the top surfaces of the inner mounting cylinder 5, the first outer fixing shell 6, and the second outer fixing shell 7. Since the first outer fixing shell 6 and the second outer fixing shell 7 will be fixed to the outside of the shaft ring 2 after installation, and the rubber protrusion ball on the outside of the shaft ring 2 can also increase the friction, it is ensured that the inner mounting cylinder 5, the first outer fixing shell 6, and the second outer fixing shell 7 can rotate synchronously with the shaft ring 2. Furthermore, the inner mounting cylinder 5 will not contact the stationary part when the seat ring 1 is fixed.

[0033] In this embodiment of the disclosure, such as Figure 6 As shown, the top of the annular plate at the bottom of the inner mounting cylinder 5 is equipped with several rolling balls arranged in a ring, and the top of the annular groove at the bottom of the seat ring 1 is also provided with a corresponding annular groove, which can reduce the friction when the inner mounting cylinder 5 rotates.

[0034] In this embodiment of the disclosure, such as Figure 1 and Figures 3-6 As shown, an arc-shaped protrusion is provided on the right side of the first outer fixing shell 6 and the left side of the second outer fixing shell 7. Two corresponding arc-shaped holes are provided on the outer side of the top of the inner mounting cylinder 5. During assembly, the first outer fixing shell 6 and the second outer fixing shell 7 can be installed on the left and right sides of the shaft ring 2 respectively and fastened together with screws. At the same time, the arc-shaped protrusions on the right side of the first outer fixing shell 6 and the left side of the second outer fixing shell 7 will be embedded in the arc-shaped holes on the outer side of the top of the inner mounting cylinder 5, thus fixing the position of the inner mounting cylinder 5.

[0035] Example 2, based on Example 1, such as Figures 1-6 As shown, the inner diameter of the central hole of the shaft ring 2 is equal to the outer diameter of the upper part of the cylinder of the inner mounting cylinder 5. The inner diameter of the central hole of the seat ring 1 is 1mm larger than the outer diameter of the upper part of the cylinder of the inner mounting cylinder 5. During use, the thicker part of the shaft will be in close contact with the top surfaces of the inner mounting cylinder 5, the first outer fixing shell 6 and the second outer fixing shell 7. Since the first outer fixing shell 6 and the second outer fixing shell 7 will be fixed on the outside of the shaft ring 2 after installation, the inner mounting cylinder 5, the first outer fixing shell 6 and the second outer fixing shell 7 can rotate synchronously with the shaft ring 2. Moreover, the inner mounting cylinder 5 can also rotate smoothly in the central hole of the seat ring 1, avoiding friction with the central hole of the seat ring 1.

[0036] The working principle of this embodiment is as follows: During assembly, first place the retainer 3 and roller 4 on top of the seat ring 1, and then install the shaft ring 2 on top of the retainer 3 and roller 4. At this time, the cylinder above the inner mounting cylinder 5 can be inserted upward through the round hole in the middle of the seat ring 1 into the round hole in the middle of the shaft ring 2. Finally, the first outer fixing shell 6 and the second outer fixing shell 7 are respectively installed on the left and right sides of the shaft ring 2 and fastened together with screws. At the same time, the arc-shaped protrusions on the right side of the first outer fixing shell 6 and the left side of the second outer fixing shell 7 will be embedded into the arc on the outer side of the top of the inner mounting cylinder 5. The inner mounting cylinder 5 can be fixed in position by the hole in the inner mounting cylinder 5. During installation, the seat ring 1 can be fixed and the rotating shaft can be inserted into the round hole in the middle of the inner mounting cylinder 5. At the same time, the thicker part of the rotating shaft will be in close contact with the top surfaces of the inner mounting cylinder 5, the first outer fixing shell 6 and the second outer fixing shell 7. Since the first outer fixing shell 6 and the second outer fixing shell 7 will be fixed on the outside of the shaft ring 2 after installation, and the rubber protrusion ball on the outside of the shaft ring 2 can also increase the friction, ensuring that the inner mounting cylinder 5, the first outer fixing shell 6 and the second outer fixing shell 7 can rotate synchronously with the shaft ring 2.
