摘　　要：功率分流传动系统具有承载能力强、传动比大、结构紧凑等优点,已被广泛应用于大功率动力传输。在各支路齿轮配齿时,考虑邻接条件和传动比条件,且避免齿轮发生碰撞的前提下,消除各对齿轮啮合时产生的干涉已成为该系统设计时需考虑的关键问题之一。本文在功率六分支同轴传动构型设计基础上,提出了一种更容易判断4个齿轮啮合是否产生干涉的判断条件,并将其与变位齿轮结合,建立了六分支人字齿轮配齿方法,该方法不仅可快速计算出使齿轮啮合不产生干涉的变位系数,而且还可以得出满足传动比要求和干涉量误差的多组方案。算例结果表明,该方法得到的齿轮参数满足各项要求,为某舰船动力系统中的六分支人字齿轮传动系统的设计提供了实用的方法和理论依据。Power shunt transmission system has been widely used in high-power transmission due to its advantages of strong bearing capacity,large transmission ratio,and compact structure.When each branch gear is fitted,the adjacency condition and transmission ratio condition are considered,and the collision between the gears is avoided,and the interference caused by each pair of gear meshing has become one of the key problems to be considered in the design of the system.Based on the six-branches coaxial transmission power configuration in this paper,a judgment condition is proposed which is easier to determine whether four gear mesh produce interference;and combined with modified gear,they established the teeth matching method of six-branch herringbone gear,which not only can quickly calculate the displacement coefficient of gear mesh not to produce interference,but also obtain the multi-group schemes satisfying transmission ratio and interference error requirements.The calculation results show that the gear design parameters obtained by this method meet all the requirements,which provides a practical method and theoretical basis for the design of a six-branch herringbone gear transmission system in a ship power system.
