所谓齿轮的噪声,一般是齿轮传动装置放射出来的噪声,所以,没有齿轮箱时噪声为齿轮本体放射出来的声波,有齿轮箱时,还有齿轮箱振动放射到空气中形成的声波。此外在齿轮传动有噪声的情况下,要避免支承齿轮轴的轴承及其他方面产生的噪声的混杂是困难的。一、没有齿轮箱时齿轮两端使用滑动轴承时,齿轮直接放射出来的声波形成齿轮噪声。齿轮振动有圆周方 The so-called gear noise is generally the noise emitted by the gear transmission. Therefore, when there is no gear box, the noise is the sound wave emitted by the gear body. When there is a gear box, there is the sound wave that the gear box vibrates and radiates into the air. In addition, in the case of gear transmission noise, it is difficult to avoid mixing of bearings that support the gear shaft and other aspects of noise. First, there is no gear box gear both ends of the sliding bearings, the gear directly emitted sound waves to form gear noise. Gear vibration has a circumference
