一、概述 近代空间技术的迅速发展,给轴承行业提出了各种各样的、不容回避的课题。各种特殊轴承,如耐高温轴承、耐低温轴承、高速轴承、防磁轴承、微摩擦力矩轴承、超精密轴承、抗放射性轴承、耐蚀轴承等相继问世。就滚动轴承的结构而论,以多点接触代替两点接触是主要的变革趋势之一,特别是 First, an overview of the rapid development of modern space technology, to the bearing industry put forward a variety of issues that can not be avoided. A variety of special bearings, such as high temperature bearings, low temperature bearings, high-speed bearings, anti-magnetic bearings, micro-friction moment bearings, ultra-precision bearings, anti-radioactive bearings, corrosion bearings have come out. In terms of the structure of a rolling bearing, replacing two contacts with multiple contacts is one of the major trends of change, especially
