DETAILED DESCRIPTION

[0029] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] like Figures 1-6 As shown, according to the first aspect of an embodiment of the present application, a cooling mechanism is provided, comprising a bearing seat 1, at least one bearing 2, a rotating shaft assembly 3 and a cooling assembly 4; the bearing seat 1 is provided with a mounting hole 12, the bearing seat 1 is provided with an air inlet 11, and the air inlet 11 is connected to the mounting hole 12; the bearing 2 is arranged in the mounting hole 12; the rotating shaft assembly 3 is connected to the inner ring of the bearing 2; the cooling assembly 4 is connected to the air inlet 11, and the cooling assembly 4 transports cold air into the mounting hole 12 through the air inlet 11.

[0035] like Figures 1-6 As shown, the cooling mechanism includes a bearing seat 1, a bearing 2 and a rotating shaft assembly 3; wherein, as Figure 3As shown, the bearing seat 1 is provided with a mounting hole 12 and an air inlet 11. The mounting hole 12 passes through the first end 14 and the second end 15 of the bearing seat 1. The air inlet 11 is provided on the outer wall of the bearing seat 1. The air inlet 11 is communicated with the mounting hole 12. The direction of the axis of the air inlet 11 intersects with the direction of the axis of the mounting hole 12. The bearing 2 is arranged in the mounting hole 12. The outer ring of the bearing 2 is fitted with the inner wall of the mounting hole 12. The shaft assembly 3 is fitted with the inner ring of the bearing 2. The shaft assembly 3 is used to install the hob. The shaft assembly 3 can rotate through the bearing 2.

[0036] Since the bearing 2 generates heat during operation, the heat generated by the bearing 2 will be transferred to the shaft assembly 3. Excessive temperature will cause the shaft assembly 3 to deform, thereby affecting the assembly accuracy of the shaft assembly 3 and the operation of the hob.

[0037] Further explanation, the cooling mechanism also includes a cooling component 4, which is connected to the air inlet 11. The cooling component 4 can transport cold air into the mounting hole 12 through the air inlet 11, and cool the bearing 2 arranged in the mounting hole 12 by the cold air, thereby avoiding the temperature increase of the rotating shaft component 3, thereby further avoiding affecting the assembly accuracy of the rotating shaft component 3 and the operation of the hob.

[0038] In an alternative embodiment, Figure 3 As shown, the cooling assembly 4 includes multiple bearings 2, each of which is disposed within the mounting hole 12. The shaft assembly 3 engages with the inner ring of each bearing 2. When multiple bearings 2 are provided, they generate a high amount of heat when operating simultaneously. Therefore, the cooling assembly 4 is more necessary to cool the bearings 2.

[0039] In an alternative embodiment, Figure 3 As shown, the cooling assembly 4 includes an air inlet nozzle 41 , which is provided at the air inlet 11 , so that the cooling assembly 4 is connected to the air inlet 11 of the bearing seat 1 through the air inlet nozzle 41 .

[0040] In a specific embodiment, the air inlet nozzle 41 includes an inner tube and an outer tube. The inner tube has an air inlet passage formed therein, which communicates with the mounting hole 12. The outer tube wraps around the outer wall of the inner tube and is embedded in the air inlet 11. The inner tube is made of metal and the outer tube is made of rubber. Therefore, the outer tube embedded in the air inlet 11 can improve the sealing between the air inlet nozzle 41 and the air inlet 11, and the inner tube is made of metal, which can improve the structural strength of the air inlet nozzle 41.

[0041] In an optional embodiment, the air inlet 11 includes a first section 111 and a second section 112, the first section 111 is connected to the second section 112, the first section 111 is close to the outer wall of the bearing seat 1, and the second section 112 is away from the outer wall of the bearing seat 1, the inner diameter of the first section 111 is larger than the inner diameter of the second section 112, and the air inlet nozzle 41 is arranged in the first section 111.

[0042] like Figure 3 and Figure 4 As shown, the air inlet 11 includes a first section 111 and a second section 112, and the first section 111 and the second section 112 are arranged in sequence, the first section 111 is close to the outer wall of the bearing seat 1, and the second section 112 is close to the inner wall of the mounting hole 12. The inner diameter of the first section 111 is larger than the inner diameter of the second section 112, so a first table 113 is formed between the first section 111 and the second section 112; the air inlet nozzle 41 is arranged in the first section 111, that is, the air inlet nozzle 41 is installed in the air inlet 11 outside the bearing seat 1, and a first table 113 is formed between the first section 111 and the second section 112, so after the air inlet nozzle 41 enters the first section 111, due to the obstruction of the first table 113, the air inlet nozzle 41 can be restricted from entering the second section 112. In other words, the air inlet nozzle 41 is restricted from entering the mounting hole 12 to prevent the air inlet nozzle 41 from contacting the rotating shaft assembly 3, so as to avoid affecting the rotation of the rotating shaft assembly 3.

[0043] The outer diameter of the end surface of the air inlet nozzle 41 that contacts the first table 113 is greater than the inner diameter of the second section 112 , so that the air inlet nozzle 41 can abut against the first table 113 .

[0044] In an optional embodiment, the air inlet nozzle 41 includes a connecting portion 411 and an annular protrusion 412, the annular protrusion 412 is arranged around the outer periphery of the connecting portion 411, at least a portion of the connecting portion 411 is arranged at the air inlet 11, and the annular protrusion 412 abuts against the outer wall of the bearing seat 1.

[0045] like Figure 3 and Figure 4 As shown, the air inlet nozzle 41 includes a connecting portion 411 and an annular protrusion 412; wherein, the annular protrusion 412 is arranged in an annular manner on the connecting portion 411, the annular protrusion 412 protrudes from the connecting portion 411, at least a portion of the connecting portion 411 will be embedded in the air inlet 11, the annular protrusion 412 protrudes from the connecting portion 411, and the annular protrusion 412 will abut against the outer wall of the bearing seat 1, so the annular protrusion 412 will play a limiting role when the air inlet nozzle 41 is installed to the air inlet 11. In other words, it limits the air inlet nozzle 41 from entering the mounting hole 12, thereby preventing the air inlet nozzle 41 from contacting the rotating shaft assembly 3, so as to avoid affecting the rotation of the rotating shaft assembly 3.

[0046] The outer diameter of the annular protrusion 412 is greater than the inner diameter of the air inlet 11 , so the annular protrusion 412 abuts against the outer wall of the bearing seat 1 .

[0047] In an alternative embodiment, Figure 6 As shown, the cooling assembly 4 also includes an air cooler 43 and a connecting pipe 42, and the connecting pipe 42 connects the air cooler 43 and the air inlet nozzle 41; specifically, the air cooler 43 is a device for producing cold air, and the air cooler 43 is connected to the air inlet nozzle 41 through the connecting pipe 42, so that the cold air produced by the air cooler 43 can be transported to the mounting hole 12 through the connecting pipe 42 and the air inlet nozzle 41 to cool the bearing 2 located in the mounting hole 12.

[0048] In an optional embodiment, the bearing seat 1 is further provided with an air outlet 13 , which is communicated with the mounting hole 12 , and the cold air entering the mounting hole 12 is discharged through the air outlet 13 .

[0049] like Figure 3 As shown, the bearing seat 1 is also provided with an air outlet 13, which is opened on the outer wall of the bearing 2, and the air outlet 13 is connected to the mounting hole 12, and the axial direction of the air outlet 13 intersects with the axial direction of the mounting hole 12; the cooling component 4 delivers cold air to the mounting hole 12 through the air inlet 11, and the cold air cools the bearing 2 in the mounting hole 12. The cold air entering the mounting hole 12 is then discharged through the air outlet 13 to avoid excessive air pressure in the mounting hole 12 affecting the components located in the bearing seat 1.

[0050] In an optional embodiment, the air inlet 11 and the air outlet 13 are symmetrically arranged along the axis of the mounting hole 12; that is, the axis of the air inlet 11 coincides with the axis of the air outlet 13. The symmetrical arrangement of the air inlet 11 and the air outlet 13 ensures a more uniform flow of cool air through the mounting hole 12, allowing the cool air to pass through the center of the mounting hole 12 when flowing through the mounting hole 12. This increases the contact area between the cool air in the mounting hole 12 and the bearing 2, thereby improving the cooling effect on the bearing 2.

[0051] like Figure 2 and Figure 3 As shown, in an optional embodiment, the air outlet 13 is provided with a dust plug 5. A gap is left between the dust plug 5 and the air outlet 13, so that cold air can pass through the air outlet 13 without being affected by the dust plug 5. The dust plug 5 can effectively prevent impurities such as dust and sand from entering the interior of the mounting hole 12, protecting the interior of the mounting hole 12 from contamination, and further increasing the service life of the bearing 2.

[0052] In an optional embodiment, the air outlet 13 includes a third section 131 and a fourth section 132, the third section 131 is connected to the fourth section 132, the third section 131 is close to the outer wall of the bearing seat 1, and the fourth section 132 is away from the outer wall of the bearing seat 1, the inner diameter of the third section 131 is larger than the inner diameter of the fourth section 132, and the dust plug 5 is arranged in the third section 131.

[0053] like Figure 3 and Figure 5 As shown, the air outlet 13 includes a third section 131 and a fourth section 132, which are arranged in sequence. The third section 131 is close to the outer wall of the bearing seat 1, and the fourth section 132 is close to the inner wall of the mounting hole 12. The inner diameter of the third section 131 is larger than the outer diameter of the fourth section 132. Therefore, a second table 133 is formed between the third section 131 and the fourth section 132; the dust plug 5 is provided in the third section 131, that is, the dust plug 5 is installed to the air outlet 13 outside the bearing seat 1, and a second table 133 is formed between the third section 131 and the fourth section 132. Therefore, after the dust plug 5 is installed to the third section 131, the second table 133 can restrict the dust plug 5 from entering the third section 131 due to the obstruction of the second table 133. In other words, the dust plug 5 is restricted from entering the mounting hole 12 to prevent the dust plug 5 from contacting the shaft assembly 3 and thus preventing the rotation of the shaft assembly 3 from being affected.

[0054] The outer diameter of the end surface of the dust plug 5 contacting the second table 133 is larger than the inner diameter of the fourth section 132 , so that the dust plug 5 can abut against the second table 133 .

[0055] In an optional embodiment, the dust plug 5 includes a first connecting section 51 and a second connecting section 52, the outer diameter of the first connecting section 51 is smaller than that of the second connecting section 52, the first connecting section 51 is arranged at the air outlet 13, and the second connecting section 52 abuts against the outer wall of the bearing seat 1.

[0056] like Figure 3 and Figure 5 As shown, the dust plug 5 includes a first connecting section 51 and a second connecting section 52, and the first connecting section 51 and the second connecting section 52 are connected in sequence. The outer diameter of the first connecting section 51 is smaller than the outer diameter of the second connecting section 52, and a third table is formed between the first connecting section 51 and the second connecting section 52. The first connecting section 51 is arranged in the air outlet 13, and the second connecting section 52 is located outside the air outlet 13. Since the outer diameter of the first connecting section 51 is smaller than the outer diameter of the second connecting section 52, the third table will abut against the outer wall of the bearing seat 1, thereby limiting the dust plug 5 from entering the mounting hole 12 to avoid contact between the dust plug 5 and the shaft assembly 3, so as to avoid affecting the rotation of the shaft assembly 3.

[0057] The outer diameter of the second connecting section 52 is greater than the inner diameter of the air outlet 13 , so that the third table surface abuts against the outer wall of the bearing seat 1 .

[0058] According to a second aspect of an embodiment of the present application, a grooving device is provided, comprising the above-mentioned cooling mechanism.
