为研究准双曲面齿轮传动机构的啮合振动、辐射噪声与传动误差的关系,建立三者之间的数据同步检测模型;并利用Y9550型锥齿轮滚动检验机搭建了综合试验平台。通过对一副准双曲面齿轮的振动与噪声信号的采集数据对比,分析振动与噪声的时域特征,并进一步分析振动与噪声谱中的频域相关特性。在Kato公式的基础上引伸出准双曲面齿轮的定量分析式,并借助传动误差的检测结果,对多次采集的数据进行以振动代替噪声的预估计算,试验结果表明:准双曲面齿轮的啮合振动能够较准确地反映出传动噪声的状态,并能够反馈到齿轮设计层面上,从而达到降低齿轮振动与噪声的目的,提高传动系统的稳定性。
In order to study the relationship between meshing vibration, radiation noise and transmission error of hypoid gear transmission mechanism, a data synchronization detection model was set up. A comprehensive test platform was built by Y9550 bevel gear rolling testing machine. By comparing the data of vibration and noise of a hypoid gear, the time-domain characteristics of vibration and noise are analyzed and the frequency-domain characteristics of vibration and noise spectrum are further analyzed. On the basis of Kato formula, the quantitative analysis of hypoid gears is extended. Based on the detection results of transmission error, the data of multiple acquisitions are estimated by using vibration instead of noise. The experimental results show that the hypoid gears The meshing vibration can reflect the state of the transmission noise more accurately and can be fed back to the gear design level to reduce the vibration and noise of the gear and improve the stability of the transmission system.
