Abstract
Description
Technical Field
[0001] This utility model relates to the field of deep groove ball bearings, and specifically to a deep groove ball bearing with a built-in heat dissipation structure. Background Technology
[0002] Deep groove ball bearings, formerly known as radial ball bearings, are one of the most widely used types of rolling bearings. They are characterized by low frictional resistance and high speed, and can be used in components that bear radial loads or combined radial and axial loads, as well as components that bear axial loads, such as small-power electric motors, automotive and tractor gearboxes, machine tool gearboxes, and general machinery and tools.
[0003] Traditional deep groove ball bearings lack heat dissipation structures, leading to overheating and expansion. This causes thermal expansion of the inner and outer rings and rolling elements, resulting in reduced clearance and potential jamming or seizing. Furthermore, high temperatures exacerbate internal friction, leading to increased wear and shortened bearing life.
[0004] Therefore, it is necessary to invent a deep groove ball bearing with a built-in heat dissipation structure to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a deep groove ball bearing with a built-in heat dissipation structure. When the inner ring rotates, it drives the connecting discs on both sides. Multiple external guide plates are angled during the rotation of the connecting discs, enhancing air convection and directing the airflow generated during rotation between the bearing race and the inner ring, thereby cooling the internal structure. Simultaneously, the guide plates on another set of connecting discs are positioned opposite to the front, allowing the airflow to be expelled during rotation. Furthermore, the cage and bearing race are made of copper alloy, and the cage is coated with a plating layer to improve heat transfer efficiency. This addresses the problems mentioned in the background art where traditional deep groove ball bearings lack a heat dissipation structure, leading to overheating and expansion. This expansion causes thermal expansion of the inner and outer rings and rolling elements, reducing the clearance and causing jamming or seizing. Additionally, high temperatures exacerbate internal friction, leading to increased wear and shortened bearing life.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep groove ball bearing with a built-in heat dissipation structure, including bearing rings;
[0007] The inner cavity, located inside the bearing ring, is used to house the rolling elements. The rolling elements are slidably connected inside the inner cavity. Cages are fitted on both sides of the outer surface of the rolling elements. Rivets are movably engaged between the cages. The outer surface of the cages is coated with a plating layer. An inner ring is provided inside the bearing ring. Threaded holes are provided on both sides of the outer surface of the inner ring.
[0008] The connecting discs are threaded onto both sides of the inner ring for heat dissipation. Each connecting disc has heat dissipation holes inside, and each connecting disc is fixedly connected to a guide plate on the outside.
[0009] Preferably, the bearing ring has limiting grooves on both sides inside, and the connecting disc is movably fitted inside the limiting grooves.
[0010] Preferably, the bearing rings and cage are made of copper alloy, and the plating is made of silver.
[0011] Preferably, the connecting disc is connected to the inner ring by bolts and threads on both sides, and the guide plate on the outside of the connecting disc is located on the side of the heat dissipation hole.
[0012] Preferably, the connecting plate is provided in two sets, and the guide plates on the outside of the two sets of connecting plates are inclined and arranged in opposite directions.
[0013] Preferably, the connecting plate has an internal mounting groove, and a dustproof plate is movably engaged inside the mounting groove.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] This invention enhances the internal heat dissipation effect through the design of a cage, plating, connecting discs, heat dissipation holes, and guide plates. When the entire deep groove ball bearing is installed on the equipment, the inner ring rotates, driving the connecting discs on both sides. The connecting discs rotate, and the external guide plates are inclined to enhance air convection by allowing the airflow generated during the rotation of the connecting discs to penetrate between the bearing race and the inner ring, thereby cooling the internal components. At the same time, the guide plates of the other set of connecting discs are arranged opposite to the front side, which can expel the penetrated air during rotation. In addition, the cage and bearing race are made of copper alloy, and the outer coating of the cage further improves the heat conduction efficiency. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-6 The deep groove ball bearing shown has a built-in heat dissipation structure and includes a bearing ring 1.
[0027] The inner cavity 3 is opened inside the bearing ring 1 and is used to place the rolling element 4. The rolling element 4 is slidably connected inside the inner cavity 3. The outer sides of the rolling element 4 are fitted with retainers 5. The retainers 5 are movably engaged with each other by rivets 6. The outer side of the retainers 5 is coated with a plating layer 7. The bearing ring 1 is provided with an inner ring 8. The outer sides of the inner ring 8 are provided with threaded holes 9.
[0028] The connecting plate 10 is threaded to both sides of the inner ring 8 for heat dissipation. Each connecting plate 10 has heat dissipation holes 11 inside, and each connecting plate 10 is fixedly connected to a guide plate 12. When the inner ring 8 rotates, it drives the connecting plates 10 on both sides. When the connecting plate 10 rotates, the multiple external guide plates 12 are inclined, which enhances the airflow generated by the rotation of the connecting plate 10 and drives the air generated by the rotation into the space between the bearing ring 1 and the inner ring 8, thereby cooling the interior. At the same time, the guide plates 12 of the other set of connecting plates 10 are set opposite to the front side, which can exhaust the air that has entered during the rotation. The cage 5 and the bearing ring 1 are made of copper alloy, and the cage 5 is coated with a plating layer 7 to improve the heat conduction efficiency.
[0029] like Figure 1 and Figure 2As shown, limiting grooves 2 are opened on both sides of the inner side of the bearing ring 1. The connecting plate 10 is movably sleeved in the limiting groove 2. The connecting plate 10 is threadedly installed on both sides of the outer side of the inner ring 8. The size of the connecting plate 10 is exactly limited in the limiting groove 2 inside the bearing ring 1, which enhances the limiting performance of the connecting plate 10 during rotation.
[0030] like Figure 3 and Figure 4 As shown, the bearing ring 1 and the cage 5 are made of copper alloy, and the plating layer 7 is made of silver. The cage 5 and the bearing ring 1 are made of copper alloy, and the outer surface of the cage 5 is coated with plating layer 7 to improve heat conduction efficiency and facilitate heat dissipation.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the connecting plate 10 is threadedly connected to both sides of the inner ring 8 by bolts 13. The guide plate 12 on the outside of the connecting plate 10 is located on one side of the heat dissipation hole 11. The connecting plate 10 is fixed to the inner ring 8 by bolts 13. During the rotation of the connecting plate 10, airflow is generated, and the airflow is guided into the heat dissipation hole 11 through the guide plate 12 to dissipate heat inside.
[0032] like Figure 1 and Figure 5 As shown, there are two sets of connecting plates 10. The guide plates 12 on the outside of the two sets of connecting plates 10 are inclined and opposite to each other. When the connecting plate 10 rotates, the inclined arrangement of the multiple external guide plates 12 enhances the air convection generated by the rotation of the connecting plate 10, and the air generated by the rotation is penetrated between the bearing ring 1 and the inner ring 8, thereby cooling and heat dissipating the interior. At the same time, the guide plates 12 of the other set of connecting plates 10 are opposite to the front side, which can exhaust the penetrated air during the rotation.
[0033] like Figure 6 As shown, the connecting plate 10 has an internal mounting groove 14, and a dustproof plate 15 is movably engaged inside the mounting groove 14. When air enters through the external heat dissipation hole 11 of the connecting plate 10, the internal dustproof plate 15 can prevent external dust from entering the interior.
[0034] The working principle of this utility model is as follows: First, the dustproof plate 15 is movably snapped onto the rear side of the connecting plate 10. Then, two sets of connecting plates 10 are placed outside the inner ring 8. Bolts 13 are aligned with the threaded holes 9 of the connecting plate 10 and the inner ring 8 and threaded through them. The connecting plates 10 are then installed on both sides of the inner ring 8. Next, the bearing ring 1 is installed and fixed to the outside of the equipment shaft. When the equipment shaft rotates, it drives the inner ring 8 and the connecting plate 10 to rotate. When the connecting plate 10 rotates, the multiple external guide plates 12 are tilted, which enhances the airflow generated by the rotation of the connecting plate 10, thus increasing air convection. Airflow enters the space between the bearing ring 1 and the inner ring 8 through the heat dissipation hole 11. At the same time, the dustproof plate 15 on the rear side of the connecting plate 10 can prevent dust from entering the interior. When the airflow enters the interior, it cools and dissipates heat. Meanwhile, the guide plate 12 of the other connecting plate 10 is set opposite to the front side, which can expel the airflow during rotation. In addition, the cage 5 and the bearing ring 1 are made of copper alloy, and the cage 5 is coated with a plating layer 7 to improve heat conduction efficiency, which can effectively dissipate heat inside. In this way, the use of the deep groove ball bearing with built-in heat dissipation structure is completed.
[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
