工程机械上大模数齿轮的表面淬火大多采用中频或火焰淬火。我厂因设备所限采用高频淬火,经多年实践,效果良好。现将该工艺中感应器内镶导磁体和多齿沟淬火的应用作一简介。一、概述我厂生产的0.6米~3机械挖掘机,齿轮共27种,大多为m=10～20的大模数齿轮,材质为40Cr、ZG40Mn、ZG40Cr和18CrMnTi等。节径大的多选铸钢件;重要性高的多选锻轧件;接触应力很大的,多选18CrMnTi渗碳淬火。大模数齿轮高频淬火的加工路线:铸锻毛坯(经退火、正火)—粗加工—调质—精加工—
Large surface modulus of gear on the construction machinery surface quenching mostly by IF or flame quenching. I plant due to equipment used by high-frequency quenching, after many years of practice, the effect is good. Now the process of induction inductivity of magnets and multi-tooth groove quenching applications for a brief introduction. First, an overview of my factory production of 0.6 m ~ 3 mechanical excavators, gear a total of 27 species, mostly m = 10 ~ 20 large modulus gear, made of 40Cr, ZG40Mn, ZG40Cr and 18CrMnTi and so on. Large diameter multi-election castings; high importance of multiple-choice forging; contact stress is great, select 18CrMnTi carburizing and quenching. Large module gear induction hardening processing route: cast forging rough (annealed, normalized) - roughing - quenching - finishing -
