不同载荷和速度下轮副在特定系统中的传动特性是大家所关心的。本文从系统的角度分析单啮运动误差是齿轮系统产生强迫振动的激励源,从建立轮副扭振的力学模型导出了相应的振动方程,说明轮副振动状态取决于单啮运动误差对时间的二阶导数△(?)′,并且认为评定齿轮的传动质量必须考虑到系统的质量、刚度、阻尼条件及固有频率和载荷速度等因素的影响,并用多次实验和所得曲线作了验证。指出在齿轮副传动过程中按实际条件的不同,存在着共振、脱啮、非工作面碰撞及越齿脱啮和共振脱啮等现象。实验和分析都证明,在确定的系统和工作条件下轮副的运动特性主要取决于静态单啮运动误差,因此深入分析动、静态误差的相互关系不仅将为探明轮副的振动、噪声等动态过程的机理,还将为以后确定“设计齿形”提供某些依据。
The transmission characteristics of wheelsets in a particular system under different loads and speeds are of concern. This paper analyzes the single-tooth motion error from the perspective of the system as an excitation source for forced vibration of gear system. The corresponding vibration equation is derived from the mechanical model of the torsional vibration of the wheel set. The vibration state of the wheel set depends on the single- Second derivative △ (?) ’, And consider the quality of the gear transmission must take into account the quality of the system, stiffness, damping conditions and the natural frequency and load speed and other factors, and verified by multiple experiments and the resulting curve. It is pointed out that there are some phenomena such as resonance, disengagement, collision of non - working face, disengagement of teeth and resonance disengagement in the process of gear pair transmission according to the actual conditions. Experiments and analyzes show that the motion characteristics of the wheelset depend on the static one-piece motion error under certain system and working conditions. Therefore, in-depth analysis of the interaction between the dynamic and static errors will not only be used to detect the vibration, noise, etc. of the wheelset The mechanism of dynamic process will also provide some basis for determining “design tooth shape” in the future.
