Half axle gear for differential mechanism

The utility model provides a half axle gear for a differential mechanism, which relates to the technical field of half axle gears and comprises a connecting rod, a disc is fixed on the top of the connecting rod, a fluted disc is fixed on the top of the disc, a circle of teeth are fixed on the bevel edge of the top of the fluted disc at equal intervals, and an annular plate is fixed on the top of the fluted disc. According to the gear, the wear-resistant layers are arranged on the surfaces of the teeth, the effect of improving the wear-resistant performance of the surfaces of the teeth can be achieved, and therefore the effect of prolonging the service life of the gear can be achieved; lubricating oil can slide in the annular groove and penetrate through the oil inlet groove and the first connecting groove to flow into the second connecting groove, and meanwhile when the lubricating oil penetrates through the second connecting groove, enters the square groove and flows to the surfaces of the teeth from round h
