大型滚珠轴承或圆锥滚子轴承在徐州NSK轴承纯径向载荷下的低速滚动冲击声及其控制方法。由于滚动体的卸料面积小，滚动体的离心力会对保持架辊产生冲击或噪声。但是随着速度的增加，声音消失了。脉冲声滚压控制方法：适当减小径向间隙，结构合理，轴承保持架灵活。
Low-speed rolling impact sound of large ball bearing or tapered roller bearing under pure radial load of Xuzhou NSK bearing and its control method. Because the unloading area of the rolling element is ***all, the centrifugal force of the rolling element will impact or noise the cage roll. But as the speed increases, the sound disappears. Pulse acoustic rolling control method: appropriate reduction of radial clearance, reasonable structure, flexible bearing cage.
吱吱作响的圆锥滚子轴承和圆柱滚子轴承的滚动控制方法一直以来都是徐州NSK轴承苛刻的金属噪声，主要是在轴承润滑脂润滑量大的情况下，有可能且更可能发生在基础油润滑脂中，很少发生油润滑劣化。
The rolling control methods of squeaky tapered roller bearings and cylindrical roller bearings h***e always been the harsh metal noise of Xuzhou NSK bearings, mainly in the case of large lubrication of bearing grease, it is possible and more likely to occur in base oil grease, and oil lubrication deterioration rarely occurs.
首先，采用***合理的结构设计，使圆锥滚子轴承具有更长的使用寿命。通过触摸轴承上的钢印，可以更快、更准确地识别轴承。***不需要用手触摸，但用钉子触摸的轴承可以感觉到***的存在。钢印通常通过锻造、热处理、车削、磨削和装配来控制。
Firstly, advanced and reasonable structure design is adopted to make tapered roller bearings h***e longer service life. By touching the steel stamp on the bearing, the bearing can be recognized more quickly and accurately. Stamps do not need to be touched by hand, but bearings touched by nails can sense the existence of stamps. Steelprints are usually controlled by forging, heat treatment, turning, grinding and assembly.
加工工艺的***性、合理性和稳定性也会影响徐州NSK轴承的使用寿命。热处理和磨削对轴承质量的影响往往与轴承失效更直接相关。对轴承表面变质层的研究表明，近年来，变质层与轴承磨削表面质量密切相关。
Advanced processing technology, rationality and stability will also affect the service life of Xuzhou NSK bearings. The influence of heat treatment and grinding on bearing quality is often more directly related to bearing failure. The research on the deteriorated layer of bearing surface shows that in recent years, the deteriorated layer is closely related to the quality of bearing grinding surface.
轴承材料的冶金质量是影响圆锥滚子轴承早期失效的主要因素。当轴承识别出轴承的真假时，通过触摸轴承上的钢印，可以更快、更准确地识别轴承。这张***不是用手触摸，而是用冶金技术轻轻地触摸徐州NSK轴承钉子上的***，你可以感觉到***的存在。
The metallurgical quality of bearing materials is the main factor affecting the early failure of tapered roller bearings. When the bearing recognizes the true or false of the bearing, it can recognize the bearing more quickly and accurately by touching the steel mark on the bearing. This stamp is not touched by hand, but by gently touching the stamp on Xuzhou NSK bearing nail with metallurgical technology, you can feel the existence of the stamp.
真空脱气钢轴承的发展可以提高材料的质量。原材料质量因素的轴承失效分析比例明显下降，但仍然是轴承失效的主要因素之一。相关材料仍然是轴承失效分析中**须考虑的因素。
The development of vacuum degassing steel bearings can improve the quality of materials. The proportion of bearing failure analysis for quality factors of raw materials has ***iously decreased, but it is still one of the main factors of bearing failure. Relevant materials are still factors to be c***idered in bearing failure analysis.
基于大量的背景数据，通过对数据的分析，不可能找出圆锥滚子轴承失效的主要原因。提出了一些改进措施，以避免徐州NSK轴承在使用寿命中出现非预期的早期失效。轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。
Based on a large number of background data, through the analysis of data, it is impossible to find out the main cause of failure of tapered roller bearings. Some improvement measures are put forward to ***oid unexpected early failure of Xuzhou NSK bearing in service life. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time.
