At present, the internal structural parameters of deep groove sealed ball bearings in China are the same as those of foreign leading companies; however, the oscillation and noise levels of such products in China are far from the foreign products; the primary reason is the influence of production and working conditions. Thinking from the bearing professional point of view; the working conditions elements can make reasonable demands on the host to deal with; and how to reduce the oscillation and noise caused by the production factors is a difficult problem for the bearing profession.
Many experiments at home and abroad indicate that the processing quality of cages, ferrules and steel balls has different effects on bearing oscillations; the processing quality of steel balls has the most significant influence on bearing oscillations; secondly, the processing quality of ferrules; The primary influencing factors are the roundness, waviness, appearance roughness, and appearance of steel balls and ferrules.
The most outstanding problem of steel ball products in China is that the oscillation value is discrete; the external defects are severe (single point, group point, pit, etc.); although the appearance roughness, scale, shape, and error are not lower than the circle level; The rear bearing has a high oscillation value; even an abnormal sound occurs; the first problem is that the waviness is not manipulated (no specification, no suitable profiling instrument); together, the vibration resistance of the machine tool is poor; the grinding wheel, the grinding disc, the coolant, and the process parameters are all difficult. On the Other hand, it is necessary to improve the management level; to prevent bumps, scratches, burns, etc. with the opportunity quality problems. About the ferrule; the most severe impact on the bearing oscillation is the channel waviness and appearance roughness. For example; small and medium
