Abstract

The invention discloses a high-performance powder metallurgy warm-pressing driven gear and a production method thereof, belonging to the field of a powder metallurgy technique. The high-performance powder metallurgy warm-pressing driven gear is characterized in that the high-performance powder metallurgy warm-pressing driven gear is mainly produced by the following components proportioning by weight: 100 parts of water atomization iron powder, 1.5 to 2 parts of copper powder, 0.8 to 1 part of nickel powder, 0.8 to 1 part of lubricant and 0.8 to 1 part of graphite powder. The production method comprises the following steps that: the materials are manufactured into high-alloy warm-pressing powder by stirring, the high-alloy warm-pressing powder is uniformly heated to 130 DEG C by a warm-pressing heating system, is delivered into a mould rack and a mould which are heated to 150 DEG C, and is pressed and manufactured into a driven gear blank with high density, and then the high-performance powder metallurgy warm-pressing driven gear is manufactured by the procedures of sintering, gear lapping with corundum, high-frequency hardening, inner bore finish machining, and the like. The high-performance powder metallurgy warm-pressing driven gear and the production method thereof reduce the running noise, reduce the production cost by 43%, save energy by 50%, reduce the labour cost by 50%, increase the service life by more than one time and have higher economic benefits and social benefits.
