弧齿锥齿轮分流传动系统适用于复杂的功率分流场合。分析了其应用于船舶传动中不同工况下的功率流向,以一种典型的工况为例,提出了弧齿锥齿轮分流传动系统几何接触的分析方法。在弧齿锥齿轮轮齿接触分析的基础上,通过综合考虑系统存在边缘接触和安装错位误差,系统各齿轮副的啮合情况,设计出了系统的齿面印痕和传动误差图,为优化系统的啮合性能和进一步分析系统各齿轮副的承载情况提供了理论依据。

The flow-dividing transmission systems of an arc-tooth cone gear are applicable for complex power flow-dividing cases.The authors have analyzed the power flow direction under different operating conditions when the systems in question are applied in a marine transmission plant.With a typical operating condition serving as an example,proposed was a method for analyzing the geometrical contact of the above transmission system.On the basis of the contact analysis of an arctooth cone gear tooth,with a comprehensive consideration of a marginal contact in the system and errors resulting from the installation mismatch and engagement of various gear pairs in the system,designed was a chart indicating the tooth surface contact footprint and transmission errors of the system,thus,providing a theoretical basis for optimizing the system gear-meshing performance and further analyzing the load-bearing condition of various gear pairs in the system.
