[0030] Reference Figures 1-2This utility model embodiment proposes an auxiliary device for simultaneous installation of the inner and outer rings of a bearing, including an inner component shaft 1 and an outer component 2. A bearing body is disposed on the outer side of the inner component shaft 1. The bearing body includes an inner bearing ring 14 and an outer bearing ring 15. The inner bearing ring 14 is disposed inside the outer bearing ring 15. A plurality of balls are rolled in a slide between the inner bearing ring 14 and the outer bearing ring 15. The outer component 2 is disposed on the outer side of the bearing body. A bottom outer ring 3 is disposed at the upper end of the bearing body. A bottom inner ring 4 is disposed at the upper end of the bottom outer ring 3. The lower end face of the bottom inner ring 4 is in close contact with the upper end face of the inner bearing ring 14 on the bearing body, and the lower end face of the bottom outer ring 3 is in close contact with the upper end face of the outer bearing ring 15 on the bearing body. The upper end of ring 4 is provided with intermediate ring 2 5, the upper end of intermediate ring 2 5 is provided with intermediate ring 1 6, and the upper end of intermediate ring 1 6 is provided with top cover 7. Through the cooperative arrangement of bottom outer ring 3, bottom inner ring 4, intermediate ring 2 5, intermediate ring 1 6 and top cover 7, the inner and outer rings on the bearing body can be installed onto the workpiece at the same time. It can also ensure that the inner and outer rings are subjected to force at the same time and evenly when the bearing body is installed, thereby ensuring the reliability and service life of the bearing body. It can also assist in the installation of bearing bodies with different inner and outer ring lengths, and is also suitable for inner part shaft 1 or outer part 2 of different lengths. It has high customization flexibility. It should be noted that the number of intermediate rings can be one, multiple or zero. This solution takes two intermediate rings as an example.

[0031] The inner wall of the bottom inner ring 4 extends downward and fits into the bottom outer ring 3. The upper surface of the bottom outer ring 3 and the lower surface of the bottom inner ring 4 are in close contact, ensuring that the bottom outer ring 3 can be securely installed on the bottom inner ring 4.

[0032] Reference Figure 2 The bottom inner ring 4 is connected to the middle ring 2 5, the middle ring 2 5 to the middle ring 1 6, and the middle ring 1 6 to the top cover 7 through the slot structure 12, so as to realize the installation between the bottom inner ring 4 and the middle ring 2 5, the middle ring 2 5 to the middle ring 1 6, and the middle ring 1 6 to the top cover 7.

[0033] The slot structure 12 includes retaining rings on the upper end face of the bottom inner ring 4, the inner wall of the second intermediate ring 5, and the inner wall of the first intermediate ring 6, as well as annular grooves on the lower end of the inner walls of the second intermediate ring 5, the first intermediate ring 6, and the top cover 7. The retaining rings on the bottom inner ring 4 are engaged in the annular grooves on the second intermediate ring 5, the retaining rings on the second intermediate ring 5 are engaged in the annular grooves on the first intermediate ring 6, and the retaining rings on the first intermediate ring 6 are engaged in the annular grooves on the top cover 7, ensuring a secure installation between the bottom inner ring 4, the second intermediate ring 5, the first intermediate ring 6, and the top cover 7, and preventing separation of the parts during use.

[0034] Reference Figure 2The intermediate ring 6, intermediate ring 5, and top cover 7 are all separated from the inner part shaft 1 and the outer part 2, which facilitates the assembly and disassembly of the intermediate ring 6, intermediate ring 5, and top cover 7.

[0035] Reference Figure 1 The top cover 7 has a cylindrical protrusion hammering point 11 in the middle part of the upper end face, which makes it easy to hammer with a vertical tool during installation, thus facilitating the installation of the bearing body.

[0036] Reference Figure 2 Disassembly ports 13 are provided between the end faces of the top cover 7 and the second intermediate ring 5, between the end faces of the second intermediate ring 5 and the first intermediate ring 6, between the end faces of the first intermediate ring 6 and the bottom inner ring 4, and between the end faces of the bottom inner ring 4 and the bottom outer ring 3. The disassembly ports 13 allow for the disassembly of various components, thereby improving the ease of use of the device.

[0037] Reference Figure 2 The disassembly opening 13 is an annular slit, and the disassembly opening 13 is narrow inside and wide outside, which can be used with wedge-like tools to disassemble the various parts, thereby facilitating the quick disassembly of each part.

[0038] The specific implementation method is as follows: When in use, place the bearing body between the inner part shaft 1 and the outer part 2, put the bottom outer ring 3 on the bottom inner ring 4, and press the lower end face of the bottom outer ring 3 against the bearing outer ring 15 on the bearing body. Then press the lower end face of the bottom inner ring 4 against the bearing inner ring 14 on the bearing body. Then, the middle ring 2 5, the middle ring 1 6 and the top cover 7 are sequentially engaged from bottom to top. After installation, the worker uses a vertical tool to hammer the hammering point 11 on the top cover 7. At this time, the inner and outer rings on the bearing body are simultaneously subjected to force until the bearing body is hammered between the inner part shaft 1 and the outer part 2, so that the bearing body is firmly installed between the inner part shaft 1 and the outer part 2. After installation, the various parts can be removed from top to bottom using a wedge-like tool. It is very convenient to use.
