Example Embodiment
[0015] A gear pair of a fuel gear pump is provided. In the gear pair, the number of teeth Z, the modulus, and the pressure angle α of the driving gear and the driven gear are the same, and the coincidence degree ε of the gear pair satisfies the relationship:
[0016] ε=Z(tanα d -tanα) / π,
[0017] Among them, addendum pressure angle
[0018] And in the gear pair, the number of teeth Z, the pressure angle α and the degree of coincidence ε also satisfy the following relationship:
[0019]
[0020] The material of the driving gear and the driven gear is AHP10V powder metallurgy tool steel.
