The ends of the guide rods 10 are connected to the limiting caps 11, and the ends of the two guide rods 10 are fixedly connected with the edge extrusion rings 12. The other group of connecting The inside of the block 9 is connected with an adjusting bolt 13 by a thread, and the end of the adjusting bolt 13 is located at the inner side of the edge of the edge extrusion ring 12 and is connected to a limiting turntable 14. The cross-section of the edge extrusion ring 12 is a right-angled trapezoid, and a limiting groove is provided at the edge of the edge extrusion ring 12 corresponding to the limiting turntable 14. The limiting turntable 14 is located in the limiting groove and rotates in a limited manner, so that the gap between the gear ring body 1 and the rotating shaft 2 can be gradually squeezed and sealed by moving the edge extrusion ring 12, thereby improving the stability between the gear ring body 1 and the rotating shaft 2 after the initial connection.

[0029] A mounting groove 15 is provided at the middle end of the top of the gear ring body 1, and an extrusion rod 16 is provided inside the mounting groove 15. The top of the extrusion rod 16 is connected with an embedded nut 17, and the bottom of the extrusion rod 16 is connected with a threaded extrusion disc 18.

The edge of the threaded extrusion disc 18 is connected with the internal thread of the inner wall of the mounting groove 15 through an external thread. Lubricating grease is accumulated inside the liquid storage sponge column 19, which is convenient for the threaded extrusion disc 18 to squeeze the liquid storage sponge column 19, so as to quickly replenish and supply the lubricating grease when in use;

[0031] The working principle and use process of the utility model are as follows: when the gear ring body 1 is connected to the rotating shaft 2, the engaging groove 3 and the transmission key 4 are first used to make the rotating shaft 2 and the gear ring body 1 aligned and connected, so that the connecting seat 7 at the end of the rotating shaft 2 can correspond to the position of the fixing seat 5, so that the gear ring body 1 and the rotating shaft 2 are preliminarily connected and fixed by the fixing seat 5, the fixing hole 6, the connecting seat 7 and the fixing screw 8;

[0032] After the gear ring body 1 and the rotating shaft 2 are initially connected and fixed, there will be a gap at the connection position between the gear ring body 1 and the rotating shaft 2, so that the pushing structure composed of the connecting block 9, the guide rod 10, the limiting cap 11, the edge extrusion ring 12, the adjusting bolt 13 and the limiting turntable 14 can be used to facilitate the edge extrusion ring 12 to move its position through the adjusting bolt 13. The conical structure design of the edge extrusion ring 12 allows its edge to fit tightly to the gap position between the rotating shaft 2 and the gear ring body 1 during the movement, so that when the rotating shaft 2 is connected to the gear ring body 1, the gap position between them can be gradually squeezed and blocked by the movement of the edge extrusion ring 12, so as to improve the stability between the gear ring body 1 and the rotating shaft 2 after the initial connection and avoid the phenomenon of loose connection of the rotating shaft 2;

[0033] The guide rod 10 slides in the connecting block 9 so that the edge extrusion ring 12 maintains position accuracy during movement to avoid displacement.

[0035] After the lubricating grease overflows into the connecting side groove 20, the conveying circular groove 21, the distribution groove 22 and the seepage groove 23 are cooperated to allow the lubricating grease to be further conveyed into the conveying circular groove 21 through the connecting side groove 20, so that the lubricating grease can enter the gear tooth gap of the ring gear body 1 through the seepage groove 23, thereby lubricating the ring gear body 1 during the transmission process, reducing mechanical wear and improving its transmission accuracy. By arranging multiple oil supply and oil delivery channels inside the ring gear body 1, on the basis of powder metallurgy technology, the ring gear body 1 can further reduce its weight, thereby making the ring gear lighter and facilitating its better rotation.
