The utility model belongs to the technical field of gears, and particularly relates to a precisely-matched gear which comprises a gear body, grooves are symmetrically formed in the front side and the rear side of the gear body, a cavity is formed in the gear body and provided with a plurality of thin holes communicated with the outside, and the thin holes are located between every two adjacent teeth of the gear body respectively. Filling pipes communicated with the cavity are arranged in the two grooves, and one-way valves are arranged in the two filling pipes; lubricating oil is injected into the cavity, and the lubricating oil gradually seeps out of the gear through the fine holes through centrifugal force generated by autorotation of the gear body, so that the lubricating oil can normally enter the meshing position of the gear body, and the lubricating effect is better. 本实用新型属于齿轮技术领域，具体涉及一种精密配合的齿轮，包括齿轮本体，齿轮本体前后两侧对称设有凹槽，齿轮本体内部设有空腔，空腔设有若干与外界连通的细孔，且若干细孔分别位于齿轮本体的相邻的两个齿之间，两个凹槽内均设有与空腔连通的加注管，两个加注管内均设有单向阀；本实用新型将润滑
