The utility model discloses a balanced axle helical gear of car, for powder metallurgy parallel axis helical gear, including setting up the pilot hole central with the denticle to and establish the skewed tooth in the denticle outer fringe, the helical angle of skewed tooth 20 the utility model discloses a balanced axle helical gear is effectively solved the metallurgical helical gear of king bolt angle high density powder of production high rigidity and is prepared the problem. It is blank to have filled high performance powder metallurgy helical gear. It is high to have the shaping green density, and the helical angle is big, and the high advantage of off -the -shelf hardness high wearing feature guarantees that the unburned bricks tooth helical angle of extrusion reaches 25, and tooth portion hardness reaches HRC50~55, and powder unburned bricks tooth portion density reaches more than the 7.2gcm3.
