Abstract: The transmission efficiency of powder metallurgy helical gear  system was discussed, contrasting that of 38CrMoAl helical gear. The effect to transmission efficiency of material was analyzed. The measuring process was carried out. It shows that on the same working condition ,the efficiency of  powder metallurgy helical gear is high than that of  38CrMoAl helical gear, in the same time, it works more steadily, with better lubricating capability and less abrasion  when meshing. It has wide applying foreground.
Key words: powder metallurgy; helical gear; meshing; transmission efficiency
