In this thesis the generation of orthogonal - aligned - shaft face gear, finite element analysis (fea) of the bend stress and contact stress of the fg drive are studied.

本文主要研究了正交面齿轮的齿面生成、正交面齿轮传动的弯曲应力和接触应力的有限元分析。

Mechanical seal: seal face, gasket and shaft seal, etc parts must be undamaged, otherwise will result in over leakage, sure to change parts with wear and tear or damage.

机械密封：密封面、密封垫及轴封等元件必须完好，否则将导致过度泄漏，对有磨损或损伤的元件必须更换。
