双圆弧齿轮在我国已有 4 0年的应用历史。从八十年代中期 ,高速齿轮采用调质中硬(30 0 HBS左右 )——精滚齿——离子氮化——珩磨工艺 ;低速重载齿轮采用调质中硬——精滚齿工艺加工的双圆弧齿轮已在生产实际中得到成功的应用。随着现代工业的发展 ,课题组针对量大面广的低速重 Double arc gear in our country has 40 years of history. Since the mid-1980s, the high-speed gears were made of medium-hard (about 300 HBS) -precise hobbing-ion nitriding-honing process; the low-speed heavy-duty gears were made of quenched and tempered medium-precision hobbing Double arc gear has been successfully applied in production. With the development of modern industry, the research group aimed at a wide range of low-speed heavy
