摘要
针对销轴位置度误差引起的齿轮位置偏移问题,分析了行星轮系内外啮合副啮合误差、时变啮合刚度及齿侧间隙,将误差作用下的激励引入到行星齿轮系统动力学模型,研究了销轴位置度误差相位对内外齿轮副动态响应及行星轮系均载特性的影响规律及作用机理,结果表明,位置度误差下齿侧间隙的减小以及负的啮合误差会导致啮合力激增,降低系统均载性能。研究结果可为人字行星齿轮系统低噪声设计加工和装配提供理论参考。
For the offset of gear position caused by the position error of pin shaft,the meshing error,time-varying meshing stiffness and gear backlash of the internal and external meshing pairs in planetary gear train are analyzed,then each excitation under the position error is introduced into the system dynamic model.The influence law and mechanism of pin position error phase on the dynamic response of internal and external gear pairs and the load sharing characteristics of star gear system are studied.The results show that the reduction of gear backlash and negative meshing error under position error will lead to the surge of meshing force and reduce the load sharing performance of the system.The research results can provide a theoretical reference for the low-noise design,machining and assembly of the herringbone star gear system.
