【摘要】 本文开展了考虑轮齿延长啮合时齿轮参数振动稳定性的研究。首先建立齿轮副参数振动分析模型,进而研究了系统稳定性分析方法,主要是状态转移矩阵的确定和稳定性判据;在此基础上,以实际应用的高速重载齿轮副为例,讨论了延长啮合与否系统稳定区间的变化情况。更多还原

【Abstract】 The research on parametric stability for spur-gear-pair system considering effect of extended tooth contact is carried out in this paper.Firstly,a torsional parametric vibration model for spur-gear-pair system is established.Then,the method for stability analysis,including two key elements(one is the derivation of state transition matrix for the system taking into account the effect of extended tooth contact;the other is the stability criterion for parametric vibration system) is presented in detail.Based on these,in order to illustrate the effect of extended tooth contact on stable and unstable regions of geared system,stable and unstable regions of a practically used high-speed and heavy load spur-gear-pair with and without taking into account effect of extended tooth contact are determined respectively.更多还原
