轴承噪声是评定轴承质量的重要指标,因为它对轴承产品质量的影响极大。 噪声就其对人体的物理和心理作用而言,是一个十分严重的问题。在当代技术发展中,无论在提高机床性能方面,增加速度或是降低噪声等方面,都不希望有振动出现,因此,作为激振体或振动传导体的滚动轴承在这方面起着决定性的作用。 滚动轴承的质量一般都是按标准规定的尺寸、形状和位置偏差来考核。尺寸偏差应控制在套圈的内、外径和宽度的公差范围之内,而位置偏差则应根据套圈沟道的径摆、侧摆和端面振摆的情况来评定;在形状偏差方面,考核的项目包括有套圈内、外径的不 Bearing noise is an important indicator of bearing quality assessment, because it has a great bearing on the quality of products. Noise is a very serious problem in terms of its physical and psychological effects on the human body. In the development of contemporary technology, no vibration is expected in terms of improving machine performance, increasing speed or reducing noise. Therefore, the rolling bearing as an oscillator or a vibration conductor plays a decisive role in this respect. The quality of rolling bearings are generally according to the standard size, shape and position deviation assessment. The dimensional deviation should be controlled within the tolerance of the inner and outer diameter and width of the ferrule, while the position deviation should be evaluated according to the diameter, the pendulum and the end face of the ferrule. In the aspect of shape deviation, Assessment items include a ring, the diameter of the non-
