轴承预紧对高速重载行星齿轮传动动态特性影响研究
|
摘要
为分析轴承预紧对高速重载行星齿轮传动系统动态特性的影响,建立高速重载行星齿轮传动动力学模型,考虑轴承预紧因素,分析行星销轴承预紧量对系统支撑刚度、固有频率、内外啮合副动态啮合力的影响。结果表明,行星销轴承预紧可以有效增加行星销支撑刚度;系统的固有频率随预紧先减小后增大,随游隙增大而增大;行星齿轮内外啮合副动态啮合力峰值随预紧增大而减小,随游隙增大而增大。研究结果可为优化高速重载行星齿轮传动的轴承预紧量提供支撑。
In order to analyze the influence of bearing preload on the dynamic characteristics of highspeed and heavy-load planetary gear transmission system,a dynamics model of high-speed heavy-load planetary gear transmission is established. Considered bearing preload factors,the preload of planetary pin bearing influence is analyzed for system support stiffness,natural frequency,internal and external Engagement vice dynamic meshing force. The results show that the planetary pin bearing preload can effectively increase the support stiffness of the planetary pin;the natural frequency of the system decreases with the preload and then increases,and increases with the increase of the clearance;the peak value of the dynamic meshing force of the internal and external meshing pairs of the planetary gear increases with the preload and then decreases,and increases with the increase of the clearance. The research results can provide support for optimizing the bearing preload of high-speed and heavy-load planetary gear transmission.
