本文采用了动态非线性齿轮振动模型(图6),考虑了KED三方面问题从能量守恒出发分析了“啮合系统”中产生“静差”的机理,推导了产生平均附加动载公式(9)又根据啮合系统和齿轮付之间关系推导了齿轮系统动载荷系数计算公式(14),从而分析了齿轮传动过程中引起振动的基本原因,揭示了影响动载荷的诸因素。作者首次利用齿轮传动系统的“静差”概念来描述静态精度,计算平均附加动载荷;从动态分析着手,解析了引起系统振动的激振力,将传统的载荷系数,动载系数和使用系数三种概念统一采用系统动载荷系数来描述。本质上反映了输入——系统——输出之间的关系:这为深入研究齿轮传动状态特性提出了新的途径。
In this paper, the dynamic non-linear gear vibration model (Figure 6) is adopted. Considering the three aspects of KED, the mechanism of “static difference” in “meshing system” is analyzed from energy conservation. Based on the relationship between the engagement system and the gear, the calculation formula of the dynamic load coefficient of the gear system is deduced (14). The basic causes of the vibration during gear transmission are analyzed, and the factors affecting the dynamic load are revealed. For the first time, the author uses the concept of “static difference” of gear transmission system to describe the static precision and calculate the average additional dynamic load. Starting from the dynamic analysis, the exciting force that causes the system vibration is analyzed. The traditional load factor, dynamic load factor, The three concepts are unified using the system dynamic load factor to describe. It essentially reflects the relationship between input-system-output: This provides a new way for further research on the characteristics of gear transmission.
