近年来,国内外许多机床厂对降低机床噪声开展了大量的研究工作。在试验研究中,一致认定挂轮架上的齿轮噪声是整台车床中较大的噪声源之一。因此各厂根据各自的情况,对挂轮架齿轮采取了各种降低噪声的措施。其主要措施有:根据克拉得尼图形原理,通过试验在某挂轮轮体上,按一定尺 In recent years, many domestic and foreign machine tool manufacturers to carry out a large number of studies to reduce machine noise. In the experimental study, it was agreed that the gear noise on the hanger was one of the larger noise sources in the entire lathe. Therefore, according to their respective plant, the gear on the rack and roll to take a variety of noise reduction measures. The main measures are: According to Craddock graphics principle, through the test on a wheel gear, according to a certain size
