[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0029] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] This embodiment provides a device for preventing particle generation, such as Figure 1 and Figure 2As shown, the device includes a throttle valve 10 and a track plate 20, wherein one end of the throttle valve 10 is connected to a liquid supply assembly, the track plate 20 is set at a preset position, a working groove is set at one end of the track plate 20, a bearing assembly 30 is set in the working groove, and a flow channel 21 is connected to the bottom end of the working groove; the throttle valve 10 is set on one side of the track plate 20 and is connected to the flow channel 21, and the liquid in the liquid supply assembly can overflow into the working groove through the flow channel 21, and the liquid can lubricate the bearing assembly 30 and dissipate heat to it. In this device, the track plate 20 is set at a preset position, and the bearing assembly 30 can work in the working groove, thereby ensuring the stability of the structure, and the liquid in the liquid supply assembly can enter the flow channel 21 through the throttle valve 10, and enter the working groove through the flow channel 21. The liquid can not only lubricate the bearing assembly 30 in the working groove, but also cool it down and dissipate heat, thereby avoiding the aggravation of the bearing wear under long-term work, and then avoiding the generation of wear particles, and improving the service life of the bearing assembly 30. It should be noted that in this embodiment, the liquid is cooling water, which is a common cooling liquid with low cost;

[0033] To further improve the heat dissipation effect, such as Figure 1 and Figure 2 As shown, the track plate 20 is provided with a drain port 22, which is connected to the working tank. In this structure, cooling water can enter the working tank through the flow channel 21, and after soaking the bearing assembly 30, it is continuously discharged from the drain port 22. With the flow of water, the bearing assembly 30 can be continuously cooled, thereby ensuring good heat dissipation and lubrication effects.

[0034] In addition, if Figure 1 As shown, the flow channel 21 and the drain port 22 are respectively arranged on both sides of the working tank. Under this structure, liquid can flow into the working tank from one side and then flow out from the other side of the working tank, avoiding the situation where cooling water is directly discharged from the drain port 22 after entering, thereby making the heat dissipation more sufficient.

[0035] Specifically, Figure 1 and Figure 2 As shown, the flow channel 21 includes a first flow hole 211, a second flow hole 212 and a third flow hole 213 that are interconnected. The first flow hole 211 is arranged along the thickness direction of the track plate 20, and the throttle valve 10 is connected to the first flow hole 211. The second flow hole 212 and the third flow hole 213 are arranged along the length direction of the track plate 20. The end of the third flow hole 213 is connected to the working groove and forms an overflow port. This structure can not only ensure that the cooling water can flow smoothly in the flow channel 21, but also because the first flow hole 211 is arranged along the thickness direction of the track plate 20, it is also convenient to install the throttle valve 10, thereby improving the convenience of installation.

[0036] It should be noted here that the bearing assembly 30 includes a plurality of bearing balls. During operation, the plurality of bearing balls can pass through the position between the overflow port and the drain port 22 in turn, and when each bearing ball passes through this position, the cooling water lubricates and dissipates heat for it, thereby ensuring sufficient lubrication and heat dissipation effects, and further being able to produce a good effect of preventing wear particles.

[0037] like Figure 1 and Figure 2 As shown, the diameter of the third flow hole 213 is greater than the diameter of the second flow hole 212. According to the Bernoulli principle, under the premise of constant flow rate, the larger the flow diameter, the smaller the pressure of fluid flow. Since the diameter of the third flow hole 213 is larger, the fluid in the second flow hole 212 can be relieved to a certain extent, thereby preventing the fluid from impacting the bearing assembly 30 with a large pressure when flowing out of the third flow hole 213, thereby improving the service life of the bearing assembly 30.

[0038] To ensure the convenience of installation, Figure 1 As shown, the liquid supply assembly includes a main liquid inlet pipe 40 and a branch pipe that are interconnected, the other end of the branch pipe is connected to the throttle valve 10, and the main liquid inlet pipe 40 is arranged on the same side as the throttle valve 10. This structure can facilitate the connection between the main liquid inlet pipe 40 and the liquid supply pump, and also facilitate the connection between the main liquid inlet pipe 40 and the throttle valve 10, reduce the complexity of the structure, improve space utilization, and also facilitate installation.

[0039] It should be noted that the throttle valve 10 and the main liquid inlet pipe 40 can be detachably connected to the track plate 20. This structure can facilitate the subsequent maintenance or replacement of the throttle valve 10 and the main liquid inlet pipe 40, thereby improving the convenience of use.

[0040] In addition, in order to improve work efficiency, multiple working grooves can be provided on the track plate 20, and the bearing assemblies 30 can be installed in the multiple working grooves. In order to ensure that the multiple bearing assemblies 30 do not generate wear particles during operation, multiple throttle valves 10 are provided, and multiple branch pipes are also provided accordingly. The multiple branch pipes are connected to the multiple throttle valves 10, and the other ends of the multiple branch pipes are connected to the main liquid inlet pipe 40. In this structure, the cooling water can be diverted to multiple branch pipes through a main liquid inlet pipe 40, and the multiple branch pipes can be diverted to multiple throttle valves 10 accordingly, thereby ensuring that the cooling water can smoothly enter the multiple working grooves to complete lubrication and heat dissipation, which not only improves work efficiency, but also greatly simplifies the overall structure, reduces costs, saves space, and effectively improves the service life of the bearing assembly 30.

[0041] To further improve the convenience of connection, multiple branch pipes are made of flexible materials (flexible hoses), and the main liquid inlet pipe 40 is made of corrosion-resistant materials. Since the branch pipes are flexible hoses, they have a certain degree of deformation ability, which makes it easier to connect the main liquid inlet pipe 40 with multiple throttle valves 10. The main liquid inlet pipe 40 is made of corrosion-resistant material (PVC-U polyvinyl chloride), which has high wear resistance and can increase service life. In addition, in this embodiment, the track plate 20 is also made of PVC-U polyvinyl chloride material.

[0042] In addition, the throttle valve 10 is made of stainless steel, which has high corrosion resistance and anti-aging ability, and its surface is not easily oxidized, which greatly increases the service life. The pipe port of the throttle valve 10 is subjected to a pressure test before use, and its pressure bearing capacity is not less than 1.2MPa, thereby improving the safety of use.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
