[0022] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] This embodiment is a self-lubricating tapered roller bearing.

[0024] As Figures 1-4 shown, it includes an inner ring 1, tapered rollers 2, a bearing race 3 and a dust cover 4. The tapered rollers 2 are installed between the outer wall of the inner ring 1 and the outer wall of the bearing race 3. The number of dust covers 4 is two groups, and the two groups of dust covers 4 are installed at both ends of the inner cavity of the inner ring 1 and the bearing race 3. An annular lubricating oil storage cavity 5 is opened inside the bearing race 3, an oil injection hole 6 is opened on the outer wall of the bearing race 3, a limit through hole 9 is opened on the inner wall of the bearing race 3, and a ball 10 is installed in the limit through hole 9.

[0025] One end of the oil injection hole 6 is communicated with the annular lubricating oil storage cavity 5; a limit hole 7 is opened at the end of the oil injection hole 6 far from the annular lubricating oil storage cavity 5, and a sealing plug 8 is clamped in the limit hole 7; the outer wall of the ball 10 is rotatably connected to the limit through hole 9; an oil-hanging groove 11 is opened on the outer wall of the ball 10.

[0026] It should be noted that the present utility model is a self-lubricating tapered roller bearing. The inner ring 1, tapered roller 2 and dust cover 4 described in the text all belong to the prior art and can be effectively known to those skilled in the art of the relevant technical field, so specific details will not be elaborated here. When in use, after opening the sealing plug 8, lubricating oil is injected into the interior of the annular lubricating oil storage cavity 5 through the position of the oil injection hole 6, and the lubricating oil is stored in the interior of the annular lubricating oil storage cavity 5. Then, the sealing plug 8 is stuck in the limit hole 7. When the inner ring 1 drives the tapered roller 2 to rotate, there is friction between the tapered roller 2 and the ball 10. When the tapered roller 2 needs to be lubricated, the friction force is relatively large, and the tapered roller 2 will drive the ball 10 to rotate. When the ball 10 rotates, it can pick up the lubricating oil inside the annular lubricating oil storage cavity 5. And through the provided oil-picking groove 11, the ball 10 can pick up the lubricating oil better, so that the lubricating oil adhered to the ball 10 can better lubricate the tapered roller 2 and improve the self-lubricating effect.

[0027] It should be noted that in this text, relational terms such as first and second (No. 1, No. 2) are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.
