老外齿轮英语

各位大虾，又要麻烦大家！！

老外的齿轮英语不是太好理解，我已经翻译了一下，但实在不太自信，因为我对此术语等不是太熟。

请各位大虾帮下忙！！


看看，给点意见！！

Metallurgical parameters:

Microstructure  tempered martensite in case
Discontinuities of continuous network of carbide not acceptable
Retained austenite should be less than 10%
Grain boundary oxidation should be less than 15 microw no free ferrite on core is acceptable

Core hardness 25-40 HRC





Heat treatment and case depth data

Finished ground surface after heat treatment

Case carburized case hardened and tempered

Converted tensile strength




Depth checking data no.15 blank checker
Check diameter
backing

factor given on this data sheet apply to conflix straight bevel gears
with localized tooth bearing.
For gears cut with non. Localized tooth bearing the stresses will be
increased 20 to 50 percent


relationship between slots and gear teeth is not important
opposite spiral grooves wrapped around o/dim intersecting @180 °displacement.



Case carburized ,case hardened and tempered
General surface hardness 58-62 hrc on gear teeth.
56 min on ground surface
General effective case depth 0.2-0.4 on gear teeth,
0.2 min on finish ground surface after heat treatment
Converted tensile strength at tooth base 105-145 kg/mm2
Converted tensile strength at core …

Case carburized ,case hardened and tempered 表面渗碳，表面硬化及回火
General surface hardness 58-62 hrc on gear teeth. 齿面硬度58-62 洛氏硬度

General effective case depth 0.2-0.4 on gear teeth  齿面有效层深度0。2-0。4 （比如如果是渗碳就是渗碳层有效深度）
