Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Embodiment one

[0026] As Figures 1-7 Indicated, according to the self-lubricating hot rolling pulley bearing structure of the embodiment of the utility model, including hot rolling pulley body 1, hot rolling pulley body 1 is provided with first lubricating assembly 2, first lubricating assembly 2 includes outer ring 201, outer ring 201 is arranged in the mounting hole of hot rolling pulley body 1, the center of outer ring 201 is provided with inner ring 202, three storage grooves 203 are opened in inner ring 202 and outer ring 201, second lubricating assembly 3 is arranged between inner ring 202 and outer ring 201, the conveying groove 204 that is communicated is opened in the inside of storage groove 203, the conveying cotton thread 205 is arranged in the inside of storage groove 203, and the inside of storage groove 203 is extended to the outside of inner ring 202 and outer ring 201 respectively at one end of conveying cotton thread 205, the outer wall of ball 302 is adapted to the outside end of conveying cotton thread 205, injection port 5 is opened in inner ring 202 and outer ring 201, unidirectional valve is arranged in the inside of injection port 5 in actual use, for avoiding dust entering and avoiding lubricating oil from leaking, and injection port 5 is communicated with storage groove 203.

[0027] In practical applications, lubricating oil is injected into the storage tank 203 through the injection port 5. The one-way valve designed inside the injection port 5 prevents dust from entering and lubricating oil from leaking. The lubricating oil in the storage tank 203 is continuously delivered to the contact point of the ball 302 by the capillary effect generated by the interaction of the conveying tank 204 and the conveying cotton thread 205. One end of the conveying cotton thread 205 extends to the outer wall of the ball 302 to ensure that the lubricating oil can be evenly distributed to the contact point of the ball 302, thereby reducing friction and wear. During the rotation of the ball 302, its outer surface comes into contact with the conveying cotton thread 205, and the lubricating oil is evenly coated on the surface of the ball 302.

[0028] Example 2:

[0029] like Figures 1-7 As shown, according to an embodiment of the present invention, a self-lubricating hot-rolled pulley bearing structure includes a second lubrication component 3 comprising two retainers 301. The retainers 301 are disposed between the inner ring 202 and the outer ring 201, and the two retainers 301 are fixedly connected by rivets. A ball 302 is disposed between the retainers 301, and six protective plates 303 are disposed around the ball 302. The protective plates 303 are made of copper alloy, and multiple graphite blocks 304 are embedded in the protective plates 303. The graphite blocks 304 are used as graphite lubricant (existing conventional methods, so they will not be described in detail). A sealing element 4 is disposed on one side of the retainer 301, and the inner and outer edges of the sealing element 4 are in contact with the inner ring 202 and the outer ring 201. The protective plates 303 and the graphite blocks 304 are adapted to the ball 302 and the retainer 301.

[0030] In practical applications, while the ball 302 is rotating, the other outer walls of the ball 302 come into contact with the protective plate 303. The graphite block 304 embedded in the protective plate 303 utilizes the self-lubricating properties of graphite to provide additional lubrication protection for the ball 302. When the ball 302 rotates, the graphite block 304 rubs against the surface of the ball 302, and the graphite particles gradually fill the tiny gap between the ball 302 and the retainer 301, further reducing the coefficient of friction. The seal 4 is installed on one side of the retainer 301, and its inner and outer edges are in close contact with the inner ring 202 and the outer ring 201, respectively, to prevent external impurities (such as iron oxide scale, dust, etc.) from entering the bearing. At the same time, the seal 4 can also prevent the leakage of lubricating oil and ensure the stability of the lubrication system.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In summary, by means of the technical scheme of the utility model, the lubricating oil is injected into the storage groove 203 through the injection port 5, the one-way valve designed inside the injection port 5 prevents dust from entering and lubricating oil from leaking, the lubricating oil in the storage groove 203 generates capillary phenomenon through the cooperation of the conveying groove 204 and the conveying cotton thread 205, continuously conveying lubricating oil to the contact point of the ball 302, one end of the conveying cotton thread 205 extends to the outer wall of the ball 302, ensuring that the lubricating oil can be evenly distributed to the contact point of the ball 302, thereby reducing friction and wear. In the rotating process of the ball 302, the outer surface thereof is in contact with the conveying cotton thread 205, and the lubricating oil is evenly applied to the surface of the ball 302, at the same time, the other outer wall of the ball 302 is in contact with the protection plate 303, the graphite block 304 embedded in the protection plate 303 utilizes the self-lubricating property of graphite to provide additional lubrication protection for the ball 302, when the ball 302 rotates, the graphite block 304 rubs against the surface of the ball 302, and graphite particles gradually fill into the tiny gap between the ball 302 and the retainer 301, further reducing the friction coefficient, the sealing element 4 is installed on one side of the retainer 301, and the inner and outer edges thereof are in close contact with the inner ring 202 and the outer ring 201 respectively, preventing foreign matters (such as oxide scale, dust, etc.) from entering the bearing interior, at the same time, the sealing element 4 can also prevent the leakage of lubricating oil, ensuring the stability of the lubricating system.
