Description

Technical Field

[0001] The utility model relates to the technical field of dustproofing of bearing seats, in particular to a bearing seat with a dustproofing function. Background Art

[0002] Bearings are widely used in machinery and equipment. They are usually installed on the equipment through bearing seats and play a very important role. The bearing seats provide the outer support point of the bearing, while the shaft serves as the inner support point of the bearing. However, the existing bearing seats have problems with concentricity and sealing after installation, which makes it easy for the bearings to bite, water ingress, dust ingress and other problems when the equipment is running, increasing the load on the bearings and causing bearing damage.

[0003] According to a publicly disclosed bearing seat with dustproof function (publication number: CN216691898U), in the above application, there is an axial hole for installing bearings and shafts in the middle of the seat body, multiple mounting holes and threaded holes are provided on the outside of the seat body, an annular dust blocking groove is provided on the right side of the seat body, and multiple oil seals are provided on the right side of the shaft hole. The bearing cover is used to seal and block dust, and rubber pads are provided on both the inside and outside to effectively isolate dust. The dust blocking effect is achieved on the inside through 2-3 groups of oil seals, and effective dust blocking effect is achieved on both the inside and outside. In addition, the bearing cover is made of copper, and the heat conductive ring is close to the bearing to achieve bearing heat dissipation.

[0004] However, in the actual use of the above equipment, although copper is a good thermal conductive material, the thermal conductivity of copper is limited. In some high-temperature or high-load applications, the copper heat conductive ring alone cannot effectively dissipate heat. In view of this, we propose a bearing seat with dustproof function. Utility Model Content

[0005] The purpose of the utility model is to provide a bearing seat with a dustproof function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing seat with dustproof function, comprising a shaft body, a side wall of the shaft body fixedly connected to the inner ring of the bearing body, an outer ring of the bearing body fixedly connected to the bearing seat body, an inner wall of the bearing seat body fixedly connected to an oil seal, the other end of the oil seal abuts against the outer wall of the shaft body, an inner wall of the bearing seat body fixedly connected to an arc-shaped sealing ring, an end of the arc-shaped sealing ring away from the bearing seat body abuts against the shaft body, the shaft body is sleeved with a heat-conducting ring, a heat-dissipating assembly is arranged in the heat-conducting ring, the heat-dissipating assembly includes a liquid storage cavity, a liquid storage cavity is arranged in the heat-conducting ring, and a baffle is fixedly connected to the inner wall of the liquid storage cavity.

[0007] Preferably, a protrusion is fixedly connected to the outer wall of the bearing cover.

[0008] Preferably, the side wall of the heat conductive ring is fixedly connected with a bearing cover, the bearing cover abuts against the inner wall of the ash retaining ring, the ash retaining ring is plugged into the bearing seat body, and the ash retaining ring and the bearing cover are fixedly connected to the bearing seat body via threaded fastening bolts.

[0009] Preferably, the arc-shaped sealing ring is configured to be arc-shaped on one side close to the outside of the bearing seat body, thereby blocking dust from entering the inner wall of the bearing seat body, thereby forming a multi-pass sealing structure to better prevent dust and other foreign impurities from entering the internal working area of ​​the bearing.

[0010] Preferably, the liquid storage chamber is arranged in a ring shape, and the coolant can circulate in the liquid storage chamber.

[0011] Preferably, the baffles are arranged in a plurality of groups, and the baffles are arranged at equal intervals and staggered on the inner wall of the liquid storage cavity, so that the flowing coolant forms a local vortex.

[0012] Compared with the prior art, the utility model provides a bearing seat with dustproof function, which has the following beneficial effects:

[0013] 1. The bearing seat with dustproof function is provided with a liquid storage cavity, a baffle and a bump. Heat is transferred through a copper heat-conducting ring to heat the coolant in the liquid storage cavity. The rotation of the bearing seat body drives the bearing cover to rotate, which further drives the heat-conducting ring to rotate. The rotation of the heat-conducting ring causes the coolant in the arc-shaped liquid storage cavity to circulate internally. When the coolant hits the baffle and forms a small eddy current, the eddy current can bring about a forced convection effect, enhance the convection heat transfer coefficient, improve the heat exchange efficiency, and improve the heat dissipation effect of the heat-conducting ring in high-temperature applications.

[0014] 2. The bearing seat with dustproof function has a protrusion fixedly connected to the outer wall of the bearing cover. The protrusion can expand the area of ​​contact with the air and heat dissipation, increase the area of ​​heat energy transferred from the surface of the object to the air, and expand the heat dissipation flux. When the bearing seat body rotates and drives the bearing cover to rotate, the airflow flows through a larger area and can take away more heat faster, thereby increasing the heat dissipation speed.

[0019] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a bearing seat with dustproof function, including a shaft body 1, a side wall of the shaft body 1 is fixedly connected to the inner ring of the bearing body 2, the outer ring of the bearing body 2 is fixedly connected to the bearing seat body 3, the inner wall of the bearing seat body 3 is fixedly connected to the oil seal 4, the other end of the oil seal 4 is abutted against the outer wall of the shaft body 1, the inner wall of the bearing seat body 3 is fixedly connected to the arc sealing ring 5, the end of the arc sealing ring 5 away from the bearing seat body 3 is abutted against the shaft body 1, the side of the arc sealing ring 5 close to the outside of the bearing seat body 3 is set to an arc shape, thereby blocking dust from entering the inner wall of the bearing seat body 3, thereby forming a multi-pass sealing structure, better blocking dust and other foreign impurities from entering the internal working area of ​​the bearing, the shaft body 1 is sleeved with the heat conductive ring 6, a heat dissipation component is arranged in the heat conductive ring 6, and the heat dissipation component includes a liquid storage cavity 10, a baffle 11 and a protrusion 12.

[0020] In one embodiment of the utility model, a liquid storage chamber 10 is provided in the heat conductive ring 6. The liquid storage chamber 10 is arranged in a ring shape. The coolant can circulate in the liquid storage chamber 10. The inner wall of the liquid storage chamber 10 is fixedly connected with a baffle 11. The number of baffles 11 is arranged in several groups. Several groups of baffles 11 are arranged at equal intervals and staggered on the inner wall of the liquid storage chamber 10, so that the flowing coolant forms a local vortex. The side wall of the heat conductive ring 6 is fixedly connected with a bearing cover 7. The outer wall of the bearing cover 7 is fixedly connected with a protrusion 12. The bearing cover 7 abuts against the inner wall of the ash retaining ring 9. The ash retaining ring 9 is plugged into the bearing seat body 3. The ash retaining ring 9 and the bearing cover 7 are fixedly connected with the bearing seat body 3 by threaded fastening bolts 8.

[0021] When the bearing body 2 rotates, heat is generated, and the heat is transferred through the copper heat-conducting ring 6, thereby heating the coolant in the liquid storage cavity 10. The rotation of the bearing seat body 3 drives the bearing cover 7 to rotate, and further drives the heat-conducting ring 6 to rotate. The rotation of the heat-conducting ring 6 causes the coolant in the arc-shaped liquid storage cavity 10 to circulate internally. When the coolant hits the baffle 11 and forms a small vortex, the vortex can bring about a forced convection effect, enhance the convective heat transfer coefficient, and improve the heat exchange efficiency. At the same time, it disrupts the fluid boundary layer, reduces thermal resistance, and reduces the influence of thermal resistance barriers on heat transfer, further improving the heat absorption effect of the coolant, and improving the heat dissipation effect of the heat-conducting ring 6 in high-temperature applications.

[0022] In addition, in order to further improve the heat dissipation effect, a protrusion 12 is fixedly connected to the outer wall of the bearing cover 7. The protrusion 12 expands the area of ​​contact with the air and heat dissipation, increases the area of ​​heat energy transferred from the surface of the object to the air, and expands the heat dissipation flux. When the bearing seat body 3 rotates and drives the bearing cover 7 to rotate, the airflow flows through a larger area and can take away more heat faster, thereby improving the heat dissipation speed.

[0023] In the utility model, when in use, heat is generated when the bearing body 2 rotates, and the heat is transferred through the copper heat-conducting ring 6, thereby heating the coolant in the liquid storage chamber 10. The bearing seat body 3 rotates to drive the bearing cover 7 to rotate, further driving the heat-conducting ring 6 to rotate. The rotation of the heat-conducting ring 6 causes the coolant in the arc-shaped liquid storage chamber 10 to circulate internally. When the coolant hits the baffle 11 and forms a small vortex, the vortex can bring about a forced convection effect, enhance the convective heat transfer coefficient, and improve the heat exchange efficiency. At the same time, it disrupts the fluid boundary layer, reduces thermal resistance, and reduces the influence of thermal resistance barriers on heat transfer, thereby further improving the heat absorption effect of the coolant. Furthermore, the outer wall of the bearing cover 7 is fixedly connected with a protrusion 12. The protrusion 12 expands the area of ​​contact with the air and heat dissipation, increases the area of ​​heat energy transferred from the surface of the object to the air, and expands the heat dissipation flux. When the bearing seat body 3 rotates to drive the bearing cover 7 to rotate, the airflow flowing through a larger area can take away more heat faster, thereby improving the heat dissipation speed.

[0024] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
