摘　　要：本文以某款精密小模数行星传动齿轮箱为对象,分析了行星轮非对称分布时安装角的计算方法及步骤,对比了不同安装角对径向力的影响,提出了安装角尽量接近均匀分布安装角有助于最小化径向力,提高系统寿命。针对非均布传动进行修形优化,降低其传递误差波动,改善齿面接触斑偏载现象,进一步改善齿轮啮合质量,提高运行寿命。This paper takes a precision small-modulus planetary gearbox as an example,analyzes the calculation method and steps of the installation angle when the planet gears are non-symmetrically distributed.It compares the effects of different installation angles on radial forces and proposes that an installation angle as close as possible to an evenly distributed one can help minimize radial forces and improve system life.It also optimizes the shape of the non-uniform transmission to reduce the fluctuation of transmission error and improve the contact patch loading of the tooth surface,further improving the gear mesh quality and increasing the service life.
