[0028] A threaded ring 11 is welded to the lower end of the sealing member 4 , and a lower threaded hole 10 is opened at the lower end of the sealing member 4 .

[0029] A slot 9 is formed at the lower end of the connector 12 , and a threaded ring 11 is clamped in the slot 9 .

[0030] A lower threaded hole 18 is formed at the lower end of the connecting member 12 , and the lower threaded hole 18 and the lower threaded hole 2 10 are on the same axis.

[0031] The surface of the circular ring member 1 is provided with a plurality of holes 2, and the surface of the circular ring member 2 3 is provided with a plurality of similar holes 2.

[0032] When it is necessary to install the agricultural machinery wheel hub bearing;

[0033] First, the circular ring member 1 is driven to move by external force, the movement of the circular ring member 1 drives the connecting member 2 13 to move, the movement of the connecting member 2 13 drives the sealing member 4 to move, the movement of the sealing member 4 drives the threaded ring 11 to move, the threaded ring 11 moves and is stuck in the groove 9. At this moment, the lower threaded hole 2 10 is connected with the lower threaded hole 1 8.

[0034] At the same time, the sealing member 4 moves to the inside of the groove 5 , and the movement of the sealing member 4 drives the upper threaded hole three 14 to move to be connected with the upper threaded hole one 6 and the upper threaded hole two 7 .

[0035] Finally, one screw is screwed into the upper threaded hole 1 6 , the upper threaded hole 3 14 and the upper threaded hole 2 7 , and then another screw is screwed into the threaded ring 11 , the lower threaded hole 2 10 and the lower threaded hole 1 8 .

[0036] When lubricant needs to be added;

[0037] First, use an external tool to unscrew the screws on the upper threaded hole 1 6, the upper threaded hole 3 14 and the upper threaded hole 2 7, and then inject lubricating oil into the upper threaded hole 1 6. The lubricating oil moves through the upper threaded hole 1 6 to the interior of the upper threaded hole 3 14, and then flows into the upper threaded hole 2 7, and finally flows between the bearing and the shaft.

[0038] Secondly, after standing for a period of time, screw the screws back into the upper threaded hole 1 6 , the upper threaded hole 3 14 and the upper threaded hole 2 7 .

[0040] By providing the slot 9 and the threaded ring 11 and placing the threaded ring 11 inside the slot 9, the positional relationship among the upper threaded hole 1 6, the upper threaded hole 2 7 and the upper threaded hole 3 14 is positioned, thereby reducing the difficulty of installing the bearing.

[0041] Working principle:

[0042] When it is necessary to install the agricultural machinery wheel hub bearing;

[0043] First, the circular ring member 1 is driven to move by external force, the circular ring member 1 drives the connecting member 2 13 to move, the connecting member 2 13 drives the sealing member 4 to move, the sealing member 4 drives the threaded ring 11 to move, the threaded ring 11 moves and is stuck in the groove 9. At this moment, the lower threaded hole 2 10 is connected with the lower threaded hole 1 8.

[0044] At the same time, the sealing member 4 moves to the inside of the groove 5 , and the sealing member 4 drives the upper threaded hole three 14 to move until it is connected with the upper threaded hole one 6 and the upper threaded hole two 7 .

[0045] Finally, one screw is screwed into the upper threaded hole 1 6 , the upper threaded hole 3 14 and the upper threaded hole 2 7 , and then another screw is screwed into the threaded ring 11 , the lower threaded hole 2 10 and the lower threaded hole 1 8 .

[0046] When lubricant needs to be added;

[0047] First, use an external tool to unscrew the screws on the upper threaded hole 1 6, the upper threaded hole 3 14 and the upper threaded hole 2 7, and then inject lubricating oil into the upper threaded hole 1 6. The lubricating oil moves through the upper threaded hole 1 6 to the interior of the upper threaded hole 3 14, and then flows into the upper threaded hole 2 7, and finally flows between the bearing and the shaft.

[0048] Secondly, after standing for a period of time, screw the screws back into the upper threaded hole 1 6 , the upper threaded hole 3 14 and the upper threaded hole 2 7 .

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
