Description

Technical Field

[0001] The utility model relates to the technical field of bearing design, and particularly relates to a wear-resistant bearing for an automobile radiator motor. Background Technique

[0002] When the existing bearing ring is in use, the bearing ring drives the internal balls to rotate. When the balls rotate, they will generate extrusion pressure on the bearing ring. After long-term use, it will cause a certain deformation of the bearing ring due to extrusion, affecting the service life of the bearing ring. And when the bearing ring works, the internal balls will generate a large frictional force with the inner and outer rings during high-speed rotation, making the balls extremely prone to wear, which in turn affects the overall service life of the bearing. Moreover, the existing design of the cooling motor bearing is relatively thin, and the performance of the rotating structure is poor. It is extremely prone to wear during long-term use, and the maintenance cost of the gear shaft bearing is high and the maintenance time is long. For this reason, a wear-resistant bearing for an automobile radiator motor is proposed. Summary of the Utility Model

Detailed implementation manners

[0024] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0025] Refer to Figures 1 to 5, an embodiment of the present utility model provides a wear-resistant bearing for an automotive radiator motor, including a bearing cylinder 1, a bearing inner ring 7, and a bearing inner side frame 9. An upper border 2 is provided above the bearing cylinder 1, a lower border 3 is provided below the bearing cylinder 1, and several groups of intermediate rotating columns 5 are provided inside the bearing cylinder 1. Above each group of intermediate rotating columns 5, a group of upper rotating columns 4 are provided, and below each group of intermediate rotating columns 5, a group of lower rotating columns 6 are provided. A bearing inner ring 7 is provided inside the intermediate rotating columns 5, and a bearing inner side frame 9 is provided at the center of the bearing inner ring 7. A number of contact structures 8 are evenly provided on the bearing inner side frame 9. The bearing structure is designed as the bearing used for the automotive radiator motor. Besides the basic functions of the bearing, the bearing is also required to have good wear-resistant and heat-dissipating structures, so that the bearing has high follow-up performance and can maintain a rotational speed highly consistent with the motor rotating shaft, ensuring the normal control operation of the automotive radiator. The bearing uses the bearing cylinder 1 as the basic support structure, and cooperates with the upper border 2 and the lower border 3 to realize the limit installation of the bearing rotating components. The upper rotating columns 4, the intermediate rotating columns 5, and the lower rotating columns 6 are all fixedly arranged inside the bearing structure. During the rotation of the motor, the upper rotating columns 4, the intermediate rotating columns 5, and the lower rotating columns 6 are all driven to rotate in the same amplitude, realizing the rotational support of the bearing components. The bearing realizes the contact between the contact structures 8 and the motor rotating shaft through the bearing inner side frame 9, that is, during the process of the DC motor controlling the high-speed operation of the motor rotating shaft, the rotating bodies inside the bearing are driven to rotate accordingly, realizing the rotational support control of the motor bearing.

[0026] The outer end of the contact structure 8 is embedded into the outer edge of the bearing inner ring 7 extending outwards, realizing the limit control of the bearing inner ring 7 on the contact structure 8. The contact structure 8 is embedded in the cross-sectional structure of the bearing inner side frame 9, and cooperates with the bearing inner side frame 9 to realize the connection setting with the motor rotating shaft. In the bearing rotating components, by restricting the installation positions and connection structures of the upper rotating column 4, the intermediate rotating columns 5, and the lower rotating columns 6, that is, the upper rotating columns 4 are all inclined inwards from bottom to top, the lower rotating columns 6 are all inclined inwards from top to bottom, the top of the intermediate rotating columns 5 gradually extends outwards and is embedded below the upper rotating columns 4, and the bottom of the intermediate rotating columns 5 gradually extends outwards and is embedded above the lower rotating columns 6. The intermediate rotating columns 5 support the setting of the upper and lower groups of inclined rotating columns. The inclined rotating columns can strengthen the support strength of the bearing inner ring 7, improve the connection strength with the motor rotating shaft, and at the same time, can enhance the follow-up control of the rotation of the motor rotating shaft on the rotating parts, realizing the structural performance of the bearing.

[0027] Refer to Figures 2 to 4, the inner ring 7 of the bearing is set as a three-section cabin body. The inner skeleton 9 of the bearing is arranged corresponding to the middle section cabin body. The inner cavity of the middle section cabin body is set as an elastic setting bin 71. The outer end of the elastic setting bin 71 is provided with a spring installation bin 72. Several groups of strong springs 73 are arranged in the inner cavity of the spring installation bin 72. A rubber damping ring 74 is arranged inside the spring installation bin 72. A group of wear-resistant abutting blocks 75 are respectively arranged inside the rubber damping ring 74 corresponding to the strong springs 73. An auxiliary wear-resistant frame 76 is arranged outside the wear-resistant abutting blocks 75. The upper and lower two groups of cabin bodies of the inner ring 7 of the bearing are set as solid structures, which can effectively improve the support structure performance of the bearing contact assembly. The inner ring 7 of the bearing uses the middle cabin body to set an elastic support assembly, and uses the elastic support assembly to provide elastic support for the inner skeleton 9 of the bearing. During the operation of the inner skeleton 9 of the bearing and the contact structure body 8 in contact with the motor rotating shaft, since the inner skeleton 9 of the bearing is more prominent than the contact structure body 8, the force can be unloaded by the elastic support assembly, and the elastic support for the inner skeleton 9 of the bearing can be realized, so that the inner skeleton 9 of the bearing and the contact structure body 8 can be controlled by the elastic support assembly to always maintain the state of direct contact with the motor rotating shaft during rotation, ensuring that the motor rotating shaft can drive the inner ring 7 of the bearing and its components to rotate synchronously.

[0028] In the middle section cabin body, the spring installation bin 72 is set by using the elastic setting bin 71. The fixed installation of the strong springs 73 is ensured in the spring installation bin 72, so that the strong springs 73 can support the rubber damping ring 74 and the wear-resistant abutting blocks 75 to realize the abutting against the wall plate of the inner skeleton 9 of the bearing. The elastic support for the inner skeleton 9 of the bearing is realized by the strong springs 73 and the abutting blocks 75. The setting of the auxiliary wear-resistant frame 76 can improve the structural performance of the inner skeleton 9 of the bearing and improve its wear resistance. During the rotation of the inner skeleton 9 of the bearing, the bearing rotation pressure and the pressure of the motor rotating shaft received by it can be absorbed by the contraction of the rubber damping ring 74 and the strong springs 73, reducing the pressure on the inner ring 9 of the bearing in contact, improving the structural performance of the inner ring 7 of the bearing, and extending the service time of the inner ring 7 of the bearing.

[0029] Refer to Figure 1 , a rubber oil injection port 11 is arranged on the outer wall of the bearing cylinder 1. An oil injection channel is arranged inside the rubber oil injection port 11. The rubber oil injection port 11 can be pierced by an oil injection needle to inject lubricating oil into the oil injection channel to realize the lubrication of the bearing assembly. The setting of the rubber oil injection port 11 does not require an oil injection sealing structure. After the oil injection needle is pulled out, the rubber can rebound to realize the sealing treatment of the oil injection channel. On the basis of ensuring the lubrication treatment of the bearing, the structural components of the lubrication device are effectively reduced, and the difficulty of its structural setting and the maintenance difficulty are reduced.

[0030] Refer to Figure 3 , a lubricating oil channel 12 is arranged on the outer wall of the middle rotating column 5. The lubricating oil channel 12 is communicated with the oil injection channel. The lubricating oil flows from the oil injection channel into the lubricating oil channel 12 to realize the lubrication treatment of the connection structure between the inner ring 7 of the bearing and the bearing cylinder 1.

[0031] The gap between the bearing cylinder 1 and each group of rotating cylinders is set as the first flow gap 13, and the gap between each group of rotating cylinders and each cabin of the bearing inner ring 7 is set as the second flow gap 14. The second flow gap 14 is communicated with the inner side framework 9 of the bearing. The lubricating oil in the lubricating oil passage 12 can flow to the periphery of each group of rotating cylinders through the first flow gap 13. The lubricating oil flowing through the rotating cylinders flows to the periphery of each cabin through the second flow gap 14, and a connection with the inner side framework 9 of the bearing is established through the second flow gap 14, so as to realize the lubrication adjustment of the whole bearing structure and ensure the rotational freedom of the whole bearing.

[0032] The top of the upper rotating cylinder 4 is inclined inward by ten degrees. The upper rotating cylinder 4 inclined inward from bottom to top can increase the fitting degree with the motor rotating shaft, improve the installation control of the bearing assembly on the motor rotating shaft. During the rotation of the upper rotating cylinder 4, the inclined angle can adjust the rotation speed of the upper rotating cylinder 4, so as to realize the speed control of the radiator motor rotation.

[0033] The bottom of the lower rotating cylinder 6 is inclined inward by ten degrees. The lower rotating cylinder 6 inclined inward from top to bottom can increase the fitting degree with the motor rotating shaft, improve the installation control of the bearing assembly on the motor rotating shaft. During the rotation of the lower rotating cylinder 6, the inclined angle can adjust the rotation speed of the lower rotating cylinder 6, so as to realize the speed control of the radiator motor rotation.

[0034] An installation limit ring 77 is provided at the bottom of the lower cabin of the bearing inner ring 7. A clamping ring is provided at the top inside the installation limit ring 77. The bearing inner ring 7 uses the lower cabin to set the installation limit ring 77 to establish a connection with the DC motor. The motor rotating shaft connection structure is embedded in the clamping ring to realize the installation of the bearing inner ring 7.

[0035] Refer to Figure 5 As shown, a first heat sink group 21 is provided at the bottom of the gap of the upper rotating cylinder 4, and a second heat sink group is provided at the top of the gap of the lower rotating cylinder 6. The first heat sink group 21 is installed at the bottom installation gap of the upper rotating cylinder 4 to absorb heat from the upper bearing structure, and the second heat sink group is set to absorb heat from the lower bearing structure. This bearing is arranged on the automotive radiator. Affected by the heat absorption of the automotive radiator itself, two heat dissipation components are arranged on the bearing, which can effectively ensure the heat dissipation protection of the bearing.

[0036] A wear-resistant bearing for an automotive radiator motor provided by an embodiment of the present utility model has the lower section of the bearing inner ring 7 installed on the motor shaft close to the motor, and the motor shaft connection structure extends into the installation limit ring 77 and snaps into the snap ring, realizing the fixed connection of the motor shaft to the bearing structure. The bearing inner ring 7 is set to fix the setting of the bearing inner skeleton 9 and the contact structure body 8. During the rotation of the motor bearing, the contact structure body 8 and the bearing inner skeleton 9 are driven to rotate. The pressure of the motor shaft on the bearing is mainly borne by the bearing inner skeleton 9 and the buffer device installed in the middle section of the bearing inner ring 7, which can effectively improve the wear-resistant performance of the bearing structure and extend the service life of the bearing. This bearing is provided with a good heat conduction and heat dissipation structure, which can quickly conduct the heat of the bearing and avoid the influence of heat accumulation on the working efficiency of the bearing.

Without departing from the spirit and scope of the present disclosure, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present utility model.
