Technical Field

[0001] The utility model relates to the technical field of hub bearings, and specifically relates to a high-strength hub bearing. Background Technique

[0002] Hub bearings are one of the crucial components in modern automobiles, motorcycles, and other wheeled vehicles. They bear the weight of the vehicle and withstand various dynamic loads during driving. High-strength hub bearings are made of high-quality materials (such as high-carbon chromium bearing steel, stainless steel, etc.) and are precision machined and heat-treated to withstand the huge radial and axial loads generated during vehicle driving.

[0003] To facilitate the installation of the hub bearing, a flange is usually fixed on the outside of the hub bearing. With long-term use, the internal rotation of the bearing causes frequent wear, while the flange is not easily damaged. When replacing the hub bearing, the overall replacement causes a certain degree of waste of resources. Therefore, a high-strength hub bearing is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-strength hub bearing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-strength hub bearing includes an outer ring and an inner ring that rotates relative to the outer ring. A protective ring is sleeved on the side of the outer ring away from the inner ring. A flange is fixedly connected to the bottom of the protective ring. Installation through-holes with equal aperture sizes are provided on the inner side of the protective ring. A screw sleeve is fixedly connected to the inner side of the installation through-hole. A screw is arranged inside the screw sleeve. The screw consists of a screw rod and a head block. A positioning groove is provided on the side of the outer ring close to the protective ring.

[0007] Preferably, the screw rod of the screw is spirally connected to the screw sleeve, and the screw rod of the screw is arranged inside the positioning groove.

[0008] Preferably, an elastic gasket is provided between the head block of the screw and the protective ring, and the screws are arranged in an equiangular array with the same center of the circle.

[0009] Preferably, an installation groove is provided on the side of the inner ring away from the outer ring. A damping rod is fixedly connected to the inner side of the installation groove. An elastic anti-slip pad is fixedly connected to one end of the damping rod. A spring is arranged on the outer side of the damping rod.

[0010] Preferably, the springs are arranged in an equiangular array with the same center of the circle, and both ends of the spring are fixedly connected to the inner ring and the elastic anti-slip pad respectively.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, a structure composed of a protective ring, mounting through holes, a bushing, screws, and positioning grooves is provided. The protective ring is sleeved on the outside of the outer ring, and the bushing is arranged through the mounting through holes on the protective ring. At the same time, without affecting the structure of the outer ring, a positioning groove is opened to adjust the angle of the protective ring so that the bushing is aligned with the positioning groove. Then, an elastic gasket is placed on the outside of the protective ring aligned with the bushing, and the screw is rotated. The screw rod of the screw sequentially passes through the elastic gasket and the bushing, and finally the screw rod of the screw enters the positioning groove, and the head block of the screw is in contact with the elastic gasket, thus completing the installation of the protective ring and the flange. Reverse operation can achieve the disassembly of the protective ring and the flange, realizing that when the bearing is worn due to frequent rotation and needs to be replaced, only the bearing part can be replaced.

In all the examples shown and discussed here, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description.

[0027] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0028] A high-strength hub bearing includes an outer ring 1 and an inner ring 2 that rotates relative to the outer ring 1. A protective ring 3 is sleeved on one side of the outer ring 1 away from the inner ring 2. A flange 4 is fixedly connected to the bottom of the protective ring 3. Mounting through holes 5 with equal aperture sizes are formed inside the protective ring 3. A screw sleeve 6 is fixedly connected to the inside of the mounting through hole 5. A screw 7 is arranged inside the screw sleeve 6. The screw 7 is composed of a screw rod and a head block. A positioning groove 9 is formed on one side of the outer ring 1 close to the protective ring 3.

[0029] The screw rod of the screw 7 is helically connected to the screw sleeve 6. The screw rod of the screw 7 is arranged inside the positioning groove 9. This setting enables the installation of the protective ring 3 and the flange 4 through the cooperation of the screw 7, the screw sleeve 6, and the positioning groove 9. An elastic gasket 8 is arranged between the head block of the screw 7 and the protective ring 3. The screws 7 are arranged in an equiangular array with the same center. This setting enables the elastic gasket 8 to provide a certain elastic pre-tightening force after the screws 7 are tightened, effectively preventing the screws 7 from loosening under vibration or external force. An installation groove 10 is opened on the side of the inner ring 2 away from the outer ring 1. A damping rod 11 is fixedly connected to the inside of the installation groove 10. One end of the damping rod 11 is fixedly connected to an elastic anti-slip pad 12. A spring 13 is arranged outside the damping rod 11. This setting enables the elastic anti-slip pad 12 to squeeze the damping rod 11 and the spring 13 when the bearing is subjected to an impact force. The damping rod 11 is installed through the installation groove 10. The spring 13 can store and release these vibration energies, while the damping rod 11 can consume these energies, thereby jointly reducing the vibration amplitude and frequency of the elastic anti-slip pad 12 and the inner ring 2, so as to achieve the purpose of protecting the bearing and extending the service life of the bearing. The springs 13 are arranged in an equiangular array with the same center. The two ends of the spring 13 are respectively fixedly connected to the inner ring 2 and the elastic anti-slip pad 12. This setting enables the installation of the spring 13, so that the spring 13 can cooperate with the damping rod 11 for use.

[0030] Workflow: A protective ring 3 is sleeved on the outside of the outer ring 1, and a screw sleeve 6 is arranged through the installation through hole 5 on the protective ring 3. At the same time, a positioning groove 9 is opened on the premise of not affecting the structure of the outer ring 1. The angle of the protective ring 3 is adjusted so that the screw sleeve 6 is aligned with the positioning groove 9. Then, the elastic gasket 8 is placed on the outside of the protective ring 3 aligned with the screw sleeve 6. The screw 7 is rotated, and the screw rod of the screw 7 passes through the elastic gasket 8 and the screw sleeve 6 in sequence. Finally, the screw rod of the screw 7 enters the positioning groove 9, and the head block of the screw 7 is fitted with the elastic gasket 8, thus completing the installation of the protective ring 3 and the flange 4. Reverse operation can realize the disassembly of the protective ring 3 and the flange 4, realizing that when the bearing is worn due to frequent rotation and needs to be replaced, only the bearing part can be replaced. The elastic anti-slip pad 12 is connected to the rotating shaft originally connected to the inner ring 2. When the bearing is subjected to an impact force, the elastic anti-slip pad 12 will squeeze the damping rod 11 and the spring 13. The damping rod 11 is installed through the installation groove 10. The spring 13 can store and release these vibration energies, while the damping rod 11 can consume these energies, thereby jointly reducing the vibration amplitude and frequency of the elastic anti-slip pad 12 and the inner ring 2, so as to achieve the purpose of protecting the bearing and extending the service life of the bearing.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
