在人们的一般印象中,由内圈、外圈、保持架和一些滚动元件组成的滚动轴承是颇为简单的机械组件。然而,实际上滚动轴承的设计和制造,乃至其正确的装配都需要较深的知识。目前,轴承应用极其广泛,对其要求多种多样,且与日俱增。为此,SKF公司对轴承进行了大量的研究并制定了发展规划。近几年来,该公司特别注意提高滚动轴承装置的可靠性。其主要原因是:要求进一步减少可能导致严重后果的突然故障和意外损坏;要求轴承具有较长的使用寿命,而无须因观察和预防性的保养而停止工作;希望采用在设计上对其性能(如负荷、速度、温度)有更高要求的滚动轴承。为什么即使一个装配正确的滚动轴承也会损坏呢?原因是多方面的。导致轴承不可能继
In the general sense of the people, by the inner ring, outer ring, cage and some rolling elements composed of rolling bearings is quite simple mechanical components. However, in fact, the design and manufacture of rolling bearings, as well as their correct assembly require a deeper knowledge. At present, the bearing application is extremely wide, its requirements are manifold and increasing. To this end, SKF company carried out a large number of bearings and developed a development plan. In recent years, the company has paid special attention to improving the reliability of rolling bearing units. The main reason for this is that it requires further reduction of sudden failures and accidental damage that can cause serious consequences; requires bearings to have a long service life without the need to stop work due to observation and preventative maintenance; Such as load, speed, temperature) have higher requirements of the rolling bearing. Why even a properly assembled rolling bearing can be damaged? The reasons are manifold. Lead to the impossible bearing
