How to improve the gear accuracy of hard tooth surface gear reducers and soft tooth surface gear reducers
Improving gear accuracy has its own emphasis on both hard and soft tooth surfaces, as follows: 1、 Hard tooth surface gear reducer Materials and Heat Treatment Priority should be given to using 20CrMnTi carburizing steel or 40CrNiMoA quenched and tempered steel, with non-metallic inclusion grade ≤ Grade 2 of GB/T 10561. The carburizing quenching adopts a stepped heating method (heating ra
