0218齿轮式空气透平压缩机的大齿轮,产品代号ZZ97.001其齿轮参数及结构尺寸较为特殊,其模数小(模数Mn=2),齿数Z=167,通常滚齿及磨齿均因其模数小、齿数特殊(大质数)而难以加工,滚齿及磨齿加工因为被加工齿轮齿数为大质数而机床不能分齿又加上大规格齿轮加工机床嫌其尺寸太小,小规格齿轮加工机床嫌其尺寸太大,就连外协加工亦无望。为此,透平厂陈晏明一反常规设计出模数Mn=1.5、Z=167特殊的分齿挂轮,尽管对YM3150E滚齿机挂轮箱及分齿传动链进行重新合理布局,但滚齿机挂轮箱箱
0218 gear type air compressor gear, product code ZZ97.001 its gear parameters and structural dimensions are more specific, the modulus is small (modulus Mn = 2), the number of teeth Z = 167, usually hobbing and grinding teeth are Because of its small modulus, a special number of teeth (large prime number) and difficult to process, hobbing and grinding because the gear teeth are machined to a large number of high quality and the machine can not be divided teeth plus large-size gear processing machine too small size, small Specifications gear processing machine too large size, even outside the Association is also hopeless processing. To this end, the turbine factory Chen Yanming an unconventional design modulus Mn = 1.5, Z = 167 special points gear, although YM3150E gear hobbing machine and gear transmission chain chain to re-rationalize the layout, but hobbing machine hanging gear box box
