摘要
基于集中质量法建立了同轴面齿轮传动系统弯扭耦合动力学模型,研究了输入齿轮浮动量计算方法,修正了系统动力学方程,定义了系统动态均载系数计算方法,通过算例,开展了输入齿轮浮动量对系统均载性能的影响分析。结果表明,输入齿轮浮动量的变化影响系统动态均载性能;两输入齿轮均浮动时,系统动态均载性能最好;某一输入齿轮单独浮动时,系统动态均载性能最差。在同轴面齿轮试验台上开展均载试验研究,验证了某一支撑结构下两输入齿轮均浮动时均载性能的可靠性。
Based on the lumped mass method,bending and torsion coupled dynamics model of the con⁃centric face gear transmission system is established.The calculation method of floating quantity of input pinion is studied,the system dynamic equation is modified,and the calculation method of dynamic load sharing coeffi⁃cient is defined.A practical calculation example is given to analyze the influence of input gear floating quantity on system load sharing performance.The results show that the dynamic load sharing performance of the system is affected by the fluctuation of the input pinion,the dynamic load sharing performance of the system is the best when the two input pinions are floating,and the dynamic load sharing performance of the system is the worst when a certain input pinion is floating alone.The load sharing performance test is carried out on the concentric face gear test bench,which verified the reliability of the load sharing performance analysis when the two input gears are floating under a certain supporting structure.
