To exactly describe the contact state and contact area of tooth surface of toroidal involute (TI) worm gearing, the authors introduced boundary condition into contact line analysis.With helix angle chosen as parameter, the criterion for the existence of meshing boundary line on the surface of TI worm gearing is derived. Results show that there can be four situations for meshing boundary line on the tooth surface of gear, namely, inexistence of meshing boundary line, a unique line, two lines, and two coincident lines. If the helix angle is equal to or slightly smaller than the bigger angle, which makes two meshing boundary lines superpose, a preferable meshing performance is obtained. Computer simulation proves the validity of the above conclusion.

本研究通过试验研究和海洋工程耐久性参数大数据集的调研,明确了中国北方海洋工程耐久性设计参数的取值、范围和分布类型。基于修正的氯离子扩散理论模型和可靠性理论,计算了浪溅区、潮汐区和水下区混凝土结构的服役寿命。设计了满足100 年或120 年服役寿命要求的混凝土配合比,并提出了保护层厚度要求。此外,对比了边界条件(Cs)和扩散系数(Df)的不同时变关系对服役寿命的影响,结果表明,本研究采用的时变关系(即Cs持续增加后保持稳定,Df持续降低后保持稳定)对于海洋环境下混凝土结构的耐久性设计具有有利效应。
