[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] Embodiments of the present utility model

[0027] Please refer to Figures 1 to 4 As shown:

[0028] To solve the problems mentioned in the technical solution, the embodiment of the present application provides a hub bearing mechanism that can improve rotational stability, including an outer ring body 1, in which balls 11 are equidistantly and movably connected, and an inner ring body 12 is rotatably connected inside the balls 11, and also includes: a heat dissipation protection mechanism and a quick-release installation mechanism;

[0029] The heat dissipation protection mechanism is used to accelerate the heat dissipation of the wheel hub bearing.

[0030] The heat dissipation protection mechanism includes a mounting ring 201, which is symmetrically arranged in the outer ring body 1. The side of the mounting ring 201 away from the ball 11 is equidistantly connected to the guide wheel 202 for rotation. The side of the guide wheel 202 away from the mounting ring 201 is fixedly connected to the first gear 203. The side of the mounting ring 201 away from the ball 11 is equidistantly connected to the second gear 204 for rotation. One side of the second gear 204 is equidistantly fixedly connected to the blade 205. The second gear 204 is meshed with the adjacent first gear 203. The blade 205 is arranged at an angle. The diameter of the second gear 204 is smaller than that of the first gear 203. Therefore, the rotation of the first gear 203 can drive the second gear 204 to rotate faster, thereby increasing the rotation speed of the blade 205, thereby improving the heat exchange effect.

[0031] Further examples: Please refer to Figures 1 to 4 As shown:

[0032] The quick-release installation mechanism includes a rotating ring 301, which is rotatably connected to the outer surface of the mounting ring 201, and a connecting piece 302 is fixedly connected to one side of the rotating ring 301, and a fixing screw 303 is threadedly connected to the top of the connecting piece 302. A fixing screw hole 304 is opened on one side of the mounting ring 201, and the fixing screw 303 is threadedly connected to the fixing screw hole 304. A supporting bar 305 is fixedly connected to one side of the rotating ring 301, and a limited insertion column 306 is fixedly connected to one side of the support bar 305. A supporting block 307 is fixedly connected to the outer surface of the mounting ring 201, and the limited insertion column 306 is fixedly plugged into the support block 307. An extrusion column 310 is fixedly connected to one side of the rotating ring 301, and a fixing column 308 is slidably connected to one side of the support block 307. A return spring 309 is fixedly connected between the fixing column 308 and the support block 307. The end of the fixing column 308 away from the support block 307 is set to be spherical, and one end of the fixing column 308 is slidably plugged into the outer ring body 1;

[0033] In the prior art, when the existing hub bearing mechanism is in use, the bearing generates heat due to friction and load when working, resulting in a temperature rise. If the bearing temperature is too high, it will accelerate the oxidation and deterioration of the lubricant, reduce the lubrication performance of the bearing, and even cause the bearing to become stuck or damaged, affecting the stability of the bearing during use. Compared with the prior art, the implementation of this embodiment, through the provision of a heat dissipation protection mechanism, utilizes the power generated by the rotation of the bearing to drive the blades 205 to rotate, which not only saves the installation of a drive source and reduces costs, but also, the rotating blades 205 will fan and accelerate the flow of air, thereby It drives and accelerates the air flow near the hub bearing, improves the heat exchange efficiency between the hub bearing and the surrounding air, and further improves the heat dissipation effect of the hub bearing, prevents the hub bearing from overheating, and improves the stability of the hub bearing during use. By rotating the rotating ring 301 once, multiple limit plugs 306 and support blocks 307, and fixed columns 308 and outer ring body 1 can be connected at the same time, which not only ensures the fixing effect of the mounting ring 201 and the outer ring body 1 during installation, enhances the stability and reliability of the entire structure, but also improves the efficiency of assembly and reduces labor costs and time costs.

[0034] Everything in the above example works as follows:

[0035] When in use, first place the mounting ring 201 to the inner surface of the outer ring body 1, the support block 307 contacts the inner surface of the outer ring body 1, and the fixing column 308 is aligned with the slot on the inner surface of the outer ring body 1, then rotate the rotating ring 301, so that the limiting plug 306 is inserted into the circular groove on one side of the support block 307, and at the same time the extrusion column 310 moves toward the fixing column 308, and the cylindrical surface of the extrusion column 310 squeezes the spherical surface of one end of the fixing column 308, thereby pushing the fixing column 308 through the support block 307 and inserted into the outer ring body 1, and the reset spring 309 is compressed. At this time, the limiting plug 306 is plugged into the support block 307, and the fixing column 308 penetrates the support block 307 and is plugged into the outer ring body 1 Then, the rotating ring 301 rotates to drive the connecting piece 302 to rotate, so that the fixing screw 303 is located above the fixing screw hole 304, and then the fixing screw 303 is rotated to make the fixing screw 303 pass through the connecting piece 302 and be inserted into the fixing screw hole 304, thereby completing the installation of the mounting ring 201. By rotating the rotating ring 301 once, the insertion of multiple limiting plugs 306 and support blocks 307, and the insertion of fixing posts 308 and outer ring body 1 can be completed at the same time, which not only ensures the fixing effect of the mounting ring 201 and the outer ring body 1 during installation, but also enhances the stability and reliability of the entire structure, while improving the efficiency of assembly and reducing labor costs and time costs;

[0036] When the wheel hub bearing is in use, the inner ring body 12 and the outer ring body 1 will rotate relative to each other. Since the outer surface of the guide wheel 202 is in contact with the outer surface of the inner ring body 12, when the inner ring body 12 rotates, the inner ring body 12 will simultaneously drive the guide wheel 202 to rotate through friction, so that the guide wheel 202 simultaneously drives the first gear 203 to rotate, and then drives the second gear 204 and the blade 205 to rotate. Since the blade 205 is tilted, the rotating blade 205 will fan and accelerate the airflow, thereby driving and accelerating the air flow near the wheel hub bearing, improving the heat exchange efficiency between the wheel hub bearing and the surrounding air, and thus improving the heat dissipation effect of the wheel hub bearing, preventing the wheel hub bearing from overheating, and improving the stability of the wheel hub bearing during use.
