[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1-4 As shown, this high-precision meshing gear includes a gear body 1, which can be divided into a left half tooth 2 and a right half tooth 3. Positioning blocks 4 are fixedly connected to both the left half tooth 2 and the right half tooth 3, and positioning grooves 5 are provided on both the left half tooth 2 and the right half tooth 3 to fit tightly against the positioning blocks 4. A fixing block 6 is provided inside the gear body 1. The detachable gear body 1 facilitates the replacement of the left half tooth 2 or the right half tooth 3. When the left half tooth 2 or the right half tooth 3 is damaged, the damaged half tooth can be replaced, reducing the replacement cost of the gear and avoiding waste of usage costs.

[0018] Preferably, a protrusion 7 integral with the fixing block 6 is provided on the outer side of the fixing block 6, and a limiting groove 8 that fits tightly with the protrusion 7 is provided on the inner side of the gear body 1. The fixing block 6 and the gear are also designed to be detachable, so that it is convenient to replace when the shaft hole 11 is worn.

[0019] Preferably, a fixing plate 9 integral with the fixing block 6 is provided on one side of the fixing block 6, and the fixing plate 9 is attached to one side of the gear body 1. A reinforcing plate 10 is provided on one side of the gear body 1. Shaft holes 11 are provided on both the fixing block 6 and the reinforcing plate 10. The reinforcing plate 10 and the fixing plate 9 work together to reinforce the gear body 1 and make the gear body 1 more stable.

[0020] Preferably, the gear body 1 has a through hole 12, and both the fixing plate 9 and the reinforcing plate 10 have plate holes 13 that cooperate with the through hole 12.
