Description
Technical Field
[0001] This utility model belongs to the field of bearing manufacturing technology, and more specifically, relates to ceramic hybrid deep groove ball bearings. Background Technology
[0002] Ceramic hybrid deep groove ball bearings are a type of rolling bearing that combines the properties of ceramics and metals. They are widely used in fields with high performance requirements. In semiconductor manufacturing equipment and high-precision optical equipment, ceramic hybrid deep groove ball bearings can meet the requirements for high precision, low friction, and corrosion resistance, ensuring the stability and reliability of the equipment. However, commonly used ceramic hybrid deep groove ball bearings have poor heat dissipation during use. The heat generated during bearing operation is not easily dissipated, which may lead to an increase in the internal temperature of the bearing, thereby affecting the performance and lifespan of the bearing. Therefore, there is a need for a new type of ceramic hybrid deep groove ball bearing. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a ceramic hybrid deep groove ball bearing, which solves the problem of poor heat dissipation in existing ceramic hybrid deep groove ball bearings during use.

The two sets of outer rings are placed on the outside of the cage, and the inner surface of the outer rings is in close contact with the surface of the rolling elements. The two sets of outer rings each have four sets of circular holes, and a set of fixing bolts is installed in each of the four sets of circular holes. The heat-conducting element A is placed on the inside of the two sets of outer rings, and the inner surface of the heat-conducting element A is in close contact with the surface of the rolling elements. The inner ring is placed on the inside of the cage.
[0005] Furthermore, four sets of small threaded tubes are fixedly connected to the upper and lower sides of the heat-conducting component A, respectively. The small threaded tubes are movably clamped in the round holes on the outer ring, and the fixing bolts engage with the small threaded tubes.
[0006] Furthermore, the outer side of the heat-conducting component A is provided with six sets of heat dissipation holes.
[0007] Furthermore, a set of sealing rings one is connected to the outer sides of the upper and lower ends of the retainer, and a set of sealing rings two is connected to the inner sides of the upper and lower ends of the retainer.
[0008] Furthermore, a heat-conducting component B is fixedly connected to the outer side of the inner ring, and the outer side of the heat-conducting component B is in close contact with the surface of the rolling element.
[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a heat-conducting component A, this utility model can effectively absorb the heat generated by the rolling friction of the rolling component through the six sets of heat dissipation holes on the outer side of the heat-conducting component A. The six sets of heat dissipation holes can also increase the heat dissipation area and accelerate the heat dissipation to the surrounding environment, thereby reducing the bearing temperature.
[0010] 2. This utility model, by setting a retainer, with a set of sealing rings connected to the outer sides of the upper and lower ends of the retainer, and a set of sealing rings connected to the inner sides of the upper and lower ends of the retainer, helps to prevent external dust, impurities, moisture and other contaminants from entering the bearing, avoiding these contaminants from causing wear, corrosion and other adverse effects on the bearing, thereby protecting the normal operation and performance of the bearing.

By setting up a heat-conducting component B, which is fixedly connected to the outer side of the inner ring and whose outer side is in close contact with the surface of the rolling element, this utility model can effectively conduct away the heat generated by the rolling friction of the rolling element, thereby improving the heat dissipation efficiency of the entire bearing and extending its service life.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0019] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a ceramic hybrid deep groove ball bearing, including an inner ring 1, an outer ring 2, a heat-conducting component A3, and a cage 5; The cage 5 has sixteen sets of round holes, and a set of rolling elements 6 are respectively installed in the sixteen sets of round holes on the cage 5. The two sets of outer rings 2 are placed on the outside of the cage 5, and the inner surface of the outer rings 2 is in close contact with the surface of the rolling elements 6. The two sets of outer rings 2 are respectively provided with four sets of round holes, and a set of fixing bolts 4 are respectively installed in the four sets of round holes. The heat-conducting element A3 is placed on the inside of the two sets of outer rings 2, and the inner surface of the heat-conducting element A3 is in close contact with the surface of the rolling elements 6. The inner ring 1 is placed on the inside of the cage 5.
[0020] Among them, such as Figure 3 As shown, four sets of small threaded tubes 8 are fixedly connected to the upper and lower sides of the heat-conducting component A3. The small threaded tubes 8 are movably clamped in the round holes on the outer ring 2, and the fixing bolts 4 engage with the small threaded tubes 8. Six sets of heat dissipation holes 7 are provided on the outer side of the heat-conducting component A3. Through the cooperation of the small threaded tubes 8 on the upper and lower sides of the heat-conducting component A3 with the round holes on the outer ring 2 and the fixing bolts 4, the heat-conducting component A3 can be stably installed on the inner side of the two sets of outer rings 2, and the inner surface is in close contact with the surface of the rolling component 6. It can absorb the heat generated by the rolling friction of the rolling component 6 in time. The six sets of heat dissipation holes 7 provided on the outer side of the heat-conducting component A3 can increase the heat dissipation area and accelerate the heat dissipation to the surrounding environment, thereby reducing the bearing temperature.
[0021] Among them, such as Figure 4 As shown, a set of sealing rings 9 are connected to the outer sides of the upper and lower ends of the cage 5, and a set of sealing rings 10 are connected to the inner sides of the upper and lower ends of the cage 5. Through the cooperation of sealing rings 9 and 10, external dust, impurities, moisture and other contaminants are prevented from entering the bearing, avoiding these contaminants from causing wear, corrosion and other adverse effects on the bearing, thereby protecting the normal operation and performance of the bearing. At the same time, sealing rings 9 and 10 are used to prevent the leakage of grease inside the bearing and maintain the bearing in a good lubrication state.
[0022] Among them, such as Figure 5 As shown, a heat-conducting component B11 is fixedly connected to the outer side of the inner ring 1, and the outer side of the heat-conducting component B11 is in close contact with the surface of the rolling component 6. By having the outer side of the heat-conducting component B11 in close contact with the surface of the rolling component 6, it is beneficial to conduct away the heat generated by the rolling friction of the rolling component 6 in a timely manner. This helps to maintain the dimensional stability and mechanical properties of the inner ring 1, reduce problems such as the decrease in bearing precision caused by thermal deformation, improve the heat dissipation efficiency of the entire bearing, improve the working environment of the bearing, and extend the service life of the bearing.
[0023] The specific usage and function of this embodiment are as follows: like Figures 1 to 5As shown, in this invention, the small threaded tubes 8 on the upper and lower sides of the heat-conducting component A3 cooperate with the round holes on the outer ring 2 and are fixed by the fixing bolts 4, so that the heat-conducting component A3 can be stably installed on the inner side of the two sets of outer rings 2, and the inner surface is in close contact with the surface of the rolling component 6. It can absorb the heat generated by the rolling friction of the rolling component 6 in time. The six sets of heat dissipation holes 7 set on the outer side of the heat-conducting component A3 can increase the heat dissipation area and accelerate the heat dissipation to the surrounding environment, thereby reducing the bearing temperature. The outer side of the heat-conducting component B11 is in close contact with the surface of the rolling component 6, which helps to conduct the heat generated by the rolling friction of the rolling component 6 away in time. This helps to maintain the dimensional stability and mechanical properties of the inner ring 1, reduce the bearing precision reduction caused by thermal deformation, and improve the overall heat dissipation efficiency of the bearing, improve the bearing working environment, and extend the bearing service life.
