Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1-3, the present invention comprises: a rotating shaft 1 and a cover plate 2 sleeved on the middle section of the rotating shaft 1,

In this embodiment, grease is preferably poured into the annular flow passage 3 from the oil inlet passage 5 and overflows from the oil outlet passage 7, so as to form a complete waterway structure.

In this implementation, it is preferred that a limiting block 10 is further sleeved on the rotating shaft 1, and the limiting block 10 is located at the upper end of the cover plate 2.

In this implementation, preferably, the outer side wall of the rotating shaft 1 is provided with a threaded section 11, and the threaded section 11 is located at the lower end of the limiting block 10.
