Further, driven gear radial section described in the utility model is in " several " font.
Further, driven gear described in the utility model uses plastic material.
Further, it is provided with driven gear described in the utility model and driven gear shape identical metal insert.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in：
1st, driven gear is designed as " several " font by this motorcycle engine oil pump assembly, is not changing driven gear wheel
In the case that tooth position is put, other positions of driven gear are raised to the pump shaft other end, and correspondingly the length of internal rotor and outer rotor can
To increase therewith and be located in the cavity formed after projection, after internal rotor and outer rotor length increase, in the same of increase pump oil amount
When do not influence to install and use；
2nd, oil pump driven gear is embedded with the metal insert consistent with gear shape, and the intensity of gear is high.
