The two ends of the first conveying channel 4 and the second conveying channel 5 are respectively communicated with the corresponding interior of the bearing seat 2. A bearing 9 is fixed to the outer sleeve of the rotating shaft 1. The points at which the two ends of the first conveying channel 4 and the second conveying channel 5 communicate with the interior of the bearing seat 2 are distributed on both sides of the bearing 9. The rotating shaft 1 can be used to rotate inside the bearing seat 2 to drive the inner tube seat 7 and the spiral blades 8 on the outer surface of the inner tube seat 7 to rotate. At this time, the rotation of the spiral blades 8 can make the grease circulate through the interior of the first conveying channel 4 and the second conveying channel 5. Since the connection points between the first conveying channel 4 and the second conveying channel 5 and the interior of the bearing seat 2 are distributed on both sides of the bearing 9, the grease can effectively pass through the interior of the bearing 9 during the circulation process, thereby realizing self-lubricating operation of the bearing 9.

[0027] Working principle: When in use, first install the structure at the specified position, and then inject grease into the first conveying channel 4, the second conveying channel 5, and the bearing seat 2. When the external driving mechanism drives the rotating shaft 1 to rotate, the inner tube seat 7 and the spiral blade 8 fixed at the end of the rotating shaft 1 rotate. The rotation of the spiral blade 8 can make the grease flow inside the bearing seat 2, and then make the grease circulate inside the first conveying channel 4 and the second conveying channel 5. Since the connection points between the first conveying channel 4 and the second conveying channel 5 and the inside of the bearing seat 2 are distributed on both sides of the bearing 9, the grease can effectively pass through the inside of the bearing 9 during the circulation process, thereby realizing self-lubricating operation of the bearing 9.
