前言随着机械技术的高度发展和多样化,相应地对轴承结构性能与品种质量也不断地提出各种各样更高的要求。为了满足这样的要求,在对现有轴承改进提高的同时,还积极开发和使用适用于特殊用途的各类特种轴承。在轴承系统中,使用得最多的是滚动轴承。现代精密滚动轴承最早问世是1900年,虽然轴承技术有很长的历史,可是,至今仍然还在不断地发展进步。譬如,更高转速、更高精度、超 Preface With the high degree of development and diversification of mechanical technology, correspondingly higher demands are placed on the structural performance and variety of bearings. In order to meet such a demand, while improving the existing bearings, it is also actively developing and using various types of special bearings suitable for special applications. In the bearing system, the most used is the rolling bearing. The earliest modern precision roller bearings come out in 1900, although the bearing technology has a long history, but still continue to progress and development. For example, higher speed, higher precision, super
