The limiting disk 2 is mounted on the base 1 and has five limiting holes 21 for placing the gear c to be ground. Ten limiting teeth 22 are protruding from the inner wall of each limiting hole 21, arranged circumferentially along the hole wall, to restrict the circumferential rotation of the gear c. The number of limiting teeth 22 can be adjusted as needed. During grinding, the gear c is horizontally positioned, meaning its end face is horizontal. The lower grinding mechanism 5 includes a lower grinding disk 51 with its grinding surface facing upwards, supporting the lower end face of the gear c within the limiting holes 21. A lower drive motor 52 is mounted below the lower grinding disk 51 to drive its circumferential rotation.

Thus, the circumferential limiting of the gear c to be ground in the limiting hole 21 is realized by the filling ring 6, and the device can be adapted to gears c to be ground of different sizes. The size of the filling ring 6 does not need to be particularly accurate, that is, it does not need to fully fill the limiting hole 21 of the gear c to be ground, because as long as the grinding disc rotates in only one direction during operation, the end surface of the gear c to be ground can be ground, and the gear c to be ground is prevented from rotating circumferentially in the limiting hole 21. The filling ring 6 can be made of hard or relatively hard silica gel material.
