Therefore, a bearing housing with heat dissipation function is proposed. Utility Model Content

[0027] The heat dissipation assembly is used for heat dissipation and cooling of the bearing housing 1. The heat dissipation assembly includes mounting posts 5, cooling fan blades 6, and a flow guide shield 7. The mounting posts 5 are used for connecting and installing the cooling fan blades 6, as shown in the attached diagram. Figure 5 As shown, a fitting protrusion is provided on the front end of the mounting post 5, and a fitting slot is provided in the middle of the cooling fan blade 6. The cooling fan blade 6 is fitted into the front end of the mounting post 5 through the fitting slot. In order to cooperate with the mounting post 5 for installation, as shown in the attached figure... Figure 4 As shown, a bolt mounting hole is provided at the end of the shaft column body. The rear end of the mounting bolt 5 is threaded and fastened to the inner side of the bolt mounting hole. The cooling fan blade 6 is fastened and pressed to the end of the shaft column body by the mounting bolt 5. The cooling fan blade 6 is connected and installed using a shaft end opening structure, which does not have many requirements on the structure of the shaft column body. The structure is simple and easy to install, allowing the device to be installed with different types of shaft column bodies, greatly improving the flexibility of the device. In order to improve the installation stability of the cooling fan blade 6, an anti-loosening washer 8 is installed on the upper part of the mounting bolt 5. The anti-loosening washer 8 is installed between the cooling fan blade 6 and the shaft column body.

[0028] The airflow guide shroud 7 is installed on the outside of the cooling fan blades 6 to guide airflow, as shown in the attached image. Figure 4 As shown, to facilitate the connection and installation of the air guide shield 7, a mounting ring seat 9 is fixed to the front of the bearing housing 1.

To facilitate air entry, an air inlet slot 10 is provided at the front of the air guide shield 7. The air inlet slot 10 is opened through the middle of the front side of the air guide shield 7, which facilitates the entry of external air. To accelerate heat dissipation, a heat dissipation channel 3 is provided through the middle of the bearing housing 1. The heat dissipation channel 3 is circumferentially and evenly opened through the middle of the bearing housing 1, which can accelerate heat dissipation and... To facilitate air circulation, an active cooling structure is adopted. The cooling fan blades 6 are installed on the end side of the shaft body using mounting pins 5. The rotation of the shaft body itself provides the drive for the cooling fan blades 6. The airflow can accelerate the conduction and dissipation of heat, improving the heat dissipation efficiency of the bearing housing 1. In order to improve the heat dissipation outside the bearing housing 1, a heat dissipation groove 2 is provided on the upper side of the bearing housing 1. The heat dissipation groove 2 is evenly and equidistantly opened on the upper side of the bearing housing 1. The groove structure can increase the heat contact conduction area between the bearing housing 1 and the air. Combined with the active airflow cooling structure, the heat dissipation efficiency of the bearing housing 1 can be further improved.

[0029] Working principle or structural principle: During installation, the bearing housing 1 is fixedly installed on the upper part of the equipment bracket by bolts and mounting screw holes 11. Then, the shaft column body is rotated and supported by the support bearing 4 and installed inside the hole in the middle of the bearing housing 1. The installation of the cooling fan blade 6 is planned according to the rotation direction and installation position of the shaft column body to determine the heat dissipation flow direction of the bearing housing 1. Taking the suction cooling method as an example, a bolt mounting hole is opened at the end of the shaft column body, so that the thread tightening direction of the bolt mounting hole is opposite to the rotation direction of the shaft column body. Then, the cooling fan blade 6 is fitted and installed on the upper part of the mounting bolt 5 according to the suction working direction. Then, the cooling fan blade 6 is fixedly installed on the end of the shaft column body by thread tightening. After completion, the guide cover 7 is aligned and fitted on the upper part of the mounting ring seat 9 and the mounting ring seat 9 is tightened by bolts to complete the installation of the device.

[0030] During operation, the cooling fan blades 6 are driven by the main body of the shaft to rotate at high speed. The high-speed rotation of the cooling fan blades 6 draws in external air from the air inlet 10 side. Then, the cold air is directed by the guide shield 7 and blown out from the heat dissipation channel 3. The active cooling of the bearing housing 1 is completed through the circulation of cold air, thereby achieving the cooling protection of the supporting bearing 4. At the same time, the passive cooling of the bearing housing 1 can be completed through the contact conduction of heat dissipation slots 2 with external air.

[0031] In summary, this bearing housing adopts an active heat dissipation structure. The cooling fan blades 6 are mounted on the end of the shaft column body using mounting bolts 5. The rotation of the shaft column body itself drives the cooling fan blades 6. Airflow accelerates heat conduction and dissipation, improving the heat dissipation efficiency of the bearing housing 1. Furthermore, heat dissipation grooves 3 and 2 are respectively provided in the middle and side of the bearing housing 1. The groove structure increases the heat contact area between the bearing housing 1 and the air. Combined with the active airflow cooling structure, the heat dissipation efficiency of the bearing housing 1 is further improved. The cooling fan blades 6 are connected and installed using a shaft end opening structure, which places few requirements on the structure of the shaft column body. The structure is simple and easy to install, allowing the device to be installed with different types of shaft column bodies, greatly improving the flexibility of the device.
