由郑州机械研究所承担的国家”六五“期间38项重点科技攻关项目,”高速双圆弧齿轮装置降低噪声的研究“课题,于1986年7月29日至31日在郑州机械研究所通过技术鉴定。该研究对双圆弧齿轮传动中齿轮的圆周线速度、载荷及轴向重合系数对噪声的影响。进行了750多次试验,积累了大量数据。试验结果表明,圆弧齿轮的主要噪声源是齿频噪声;双圆弧齿轮噪声比单圆弧齿轮噪声低;采用整数倍轴向重合系数并使两边半个人
The key project of 38 key scientific and technological projects undertaken by Zhengzhou Machinery Research Institute during the “6th Five-year Plan” period and the project of “Research on Noise Reduction of High Speed Double Arc Gear Device” were held in Zhengzhou Machinery Research Institute from July 29 to July 31, 1986 Technical appraisal The research on the circular arc gear drive in the circumferential line speed, load and axial coincidence coefficient of the noise. More than 750 trials were conducted, accumulating a large amount of data. The test results show that the main noise source of arc gear is tooth-frequency noise; the noise of double-circular arc gear is lower than the noise of single-arc gear; the axial coincidence coefficient is an integer multiple,
