摘要
高速轴的固有特性和其质量不平衡响应严重影响高速齿轮箱的运行工况和使用寿命。针对高速齿轮轴建立了系统多分布质量模型,采用传递矩阵法,分析了轴系的固有频率及其不平衡响应,得到转子本身及转子支撑系统的固有特性以及轴系在相同位置、不同工况下的不平衡响应。通过分析各种情况下不平衡响应的特性,考察轴系上齿轮啮合点处的不平衡响应,进而反应齿轮啮合点处的工作情况,为高速齿轮箱的设计制造提供依据。
The inherent characteristics of the high speed shaft and the unbalance response of the high speed shaft seriously affect the operating condition and service life of the high speed gearbox. For the high speed gear shaft,a multi distribution model of the system is established. The natural frequency and the unbalance response of the shaft are analyzed by using the transfer matrix method. The unbalance response of the shaft at different speeds and different eccentric quality is obtained with the same method. The unbalance response of the gear meshing point is investigated through the analysis of the unbalanced response characteristics in various cases,and the working conditions of the gear meshing point are analyzed,and the basis for the design and manufacture of high speed gear box is provided.
