How to control the waviness in the grinding of cylindrical roller bearings?In the production of cylindrical roller bearings, there are also differences in quality levels due to differences in the skill level of manufacturers. After low-quality bearings are combined with other parts, vibration and noise will occur during operation. The main reason for this problem is that the waviness is not well controlled. As far as the super-finishing process is concerned , Although it can reduce the waviness of the bearing. But it is not the fundamental method to reduce the waviness. The fundamental method is to strictly control the waviness during the grinding process of the bearing. In the process of grinding the bearing, one should be reduced and the other should be improved. The so-called "one reduction" refers to reducing the error in the grinding of cylindrical roller bearings to reflect the outer diameter and end surface, the so-called "one improvement" refers to improving the accuracy of the reference surface of the bearing processing. As for the former, this is because the error reflection of the outer diameter to the groove grinding and the groove grinding to the groove super directly affect the error reflection of the outer diameter to the groove. The appearance of this situation, especially when the error is large, will inevitably lead to the appearance of bearing vibration and the increase of waviness. As for the latter, the adoption of this measure has an important effect on the smoothness of bearing processing. To control the waviness, it is necessary to reduce the occurrence of vibration. In the processing of cylindrical roller bearings, the method of reducing the shape accuracy or surface texture quality of the processed surface of the bearing can be used to control the vibration. In addition, for machine tool equipment processing bearings, it must also have excellent anti-vibration performance. Generally speaking, because the grinding process of the bearing is carried out under the condition of high-speed operation, the good anti-vibration performance of the machine tool has a great influence on the improvement of the grinding speed. In order to improve the performance of bearing products and avoid the occurrence of vibration or noise of steel balls, ferrules and other parts, it is necessary to reduce the waviness in the bearing grinding process. |
