立式车床降低噪声的实验研究

Experimental Study on Noise Reducing for Vertical Lathe

通过噪声测量和频谱分析 ,对CB3640 - 2立式双轴半自动车床主传动系统的噪声进行了实验研究。根据频谱分析结果 ,找到了对系统噪声影响最大的传动零件 ,用齿轮设计的最新技术对其进行了改进设计 ,达到了整机噪声降低 3dB(A)

In this paper, the noise of vertical lathe with double spindles was researched by noise measurement and noise spectrum analysis. According to the result, two gears are found and re-designed, which have main contribution for system noise, the noise of this vertical lathe has been reduced for 3 dB.(A)
