How does the ball mill reduce noise?

At present, my country's deep ditch sealing ball bearings are almost the same, and the vibration and noise level of such products in my country is far from foreign products, main causes are manufacturing and conditional factors. Impact. ball mills are considered from the bearing industry, and the working conditions can be resolved for the host, and how to reduce the vibration and noise caused by the manufacture factor is the problem that the bearing industry must solve.

 Whether it is steel ball or a ferrule, the corrugation is generated from grinding processing, although the superfine research can improve the corrugation and reduce the roughness, the fundamental measures are to reduce grinding The corrugations in the super-fine process avoid randomness, mainly two measures:

First, the vibration of the rolling surface grinding superfines, the ball mill obtains a good surface processing shape accuracy and surface texture Quality is to reduce vibration, and the milling minimum machine must have good vibration resistance, and the bed and other important structural parts have an absorbent property. The oil stone oscillation system of the super-fine machine has good anti-vibration performance; improve the grinding speed, foreign grinding 6202 The roller is generally used with a 60,000-electric spindle. The grinding speed is 60m / s or more, and the domestic general is much lower, mainly due to the limits of the main shaft and the main bearing performance. When high-speed grinding, the grinding force is small, the grinding is thin, and it is not easy to burn, and the machining accuracy and efficiency can be improved. The low noise ball bearing is very affected; the spindle rustic stiffness and its speed characteristics pair low noise ball bearings The grinding vibration has a large influence, the higher the stiffness, the less sensitive variation of the grinding force, the smaller the grinding system; improve the spindle bearing rigidity, use the rapid balance technology, improve the grinding spindle sex.

The second is to improve the precision of the processing benchmark surface, reducing the error of the abrasive overter processing and the end face is the positioning reference during the machining process. The error of the outer diameter to the channel super-fine is reflected by the outer diameter pair of trench, and the trench is completed by the error of the ditch. If the workpiece generates bumps during the transfer, it will be directly recited to the surface of the raceway, and the ball mill affects the bearing vibration. Therefore, the following measures must be taken: increase the shape accuracy of the positioning reference surface; during the processing, the transfer is smooth, no hike; the blanket remains the image error cannot be too large, especially when the amount is small, the excessive error will cause final grinding and super fine The shape accuracy in the end has not improved the quality requirements of the final, which seriously affects the consistency of processing quality.
