一种汽车发动机直联式喷油泵分体齿轮
摘要：
本发明公开了一种汽车发动机直联式喷油泵分体齿轮，包括齿轮基体，所述齿轮基体中心处设有中心孔，所述中心孔一侧设有卡槽，所述齿轮基体外缘设有凹齿，所述齿轮基体两侧均设有定位孔，所述齿轮基体两侧还卡紧有第一分体齿牙和第二分体齿牙，所述第一分体齿牙和第二分体齿牙内侧均设有定位柱，且定位柱卡紧于定位孔中。本发明通过第一分体齿牙和第二分体齿牙的组合设置，可以使得第一分体齿牙、第二分体齿牙和齿轮基体组合为完整的齿轮，同时第一分体齿牙与第二分体齿牙均采用定位柱与定位孔的配合进行固定，同时凹齿和凸齿的配合使得第一分体齿牙与第二分体齿牙与齿轮基体固定紧实。
摘要（英）：

The invention discloses a split gear of a directly-connected fuel injection pump of an automobile engine. The split gear comprises a gear matrix; a center hole is formed in the center of the gear matrix; a clamping slot is formed in one side of the center hole; the outer edge of the gear matrix is provided with concave teeth; locating holes are formed in two sides of the gear matrix; first split teeth and second split teeth are also clamped at two sides of the gear matrix; the inner sides of the first split teeth and the second split teeth are provided with locating columns; and the locating columns are clamped into the locating holes. Due to the combined arrangement of the first split teeth and the second split teeth, the first split teeth, the second split teeth and the gear matrix can be combined into an integrated gear, the first split teeth and the second split teeth are fixed by the matching of the locating columns and the locating holes, and meanwhile, the first split teeth and the second split teeth are tightly fixed together with the gear matrix by the matching of the concave teeth and convex teeth.
