现在苏联研制出广泛应用的外齿圈冷轧新工艺,用于冷轧精度低于8级的外齿圈成品或为冷加工供坯.外齿圈冷轧的新工艺在成形过程中,齿形工具(凹模)和坯料是不动的(图1).
Now the Soviet Union has developed a widely used new cold-rolled outer ring gear new technology for the cold-rolled precision of less than 8 finished outer ring gear or cold for the blanking of the outer ring cold-rolled in the forming process, the tooth profile Tools (die) and blank are not moving (Figure 1).
