摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing capable of responding to high-speed rotation while minimizing the radial dimension and axial dimension thereof. SOLUTION: This rolling bearing has an inner ring 1 having a first raceway 11 on its outer periphery, an outer ring 3 having a second raceway 31 on its inner periphery, an intermediate ring 2 placed between the inner and outer rings, having a third raceway 21 on its inner periphery, and having a fourth raceway 22 on its outer periphery, first rolling bodies 4 placed between the first raceway 11 and the third raceway 21, and second rolling bodies 5 placed between the fourth raceway 22 and the second raceway 31. The intermediate ring 2 has a large diameter ring section 7 and a small diameter ring section 6 provided with an inclined ring section 15 in between. The third raceway 21 is formed at the boundary between the large diameter ring section 7 and the inclined ring section 15, and the fourth raceway 22 is formed at the boundary between the small diameter ring section 6 and the inclined ring section 15.

摘要： PROBLEM TO BE SOLVED: To provide a touchdown bearing which is excellent in durability as compared with a case where a conventional ball of stainless steel or bearing steel is used, and which can get rid of idle rotation occurring at the time of non-touchdown and inferiority in adhesion property of solid lubricant resulting from the difficulty in surface treatment, as in case of using a ball of ceramics. SOLUTION: The ball 3 is formed of high-speed tool steel, thereby improving the hardness at the temperature (200 to 300°C) expected at the time of touchdown, as compared with stainless steel or bearing steel used for an inner ring 1 or an outer ring 2. Accordingly, early damage by heat generation of the ball 3 is prevented, and the durability of the bearing is improved. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供与使用不锈钢或轴承钢的常规球的情况相比，耐久性优异的触地轴承，并且可以摆脱在非时间时发生的怠速旋转由于难以进行表面处理而导致的固体润滑剂的粘附性的下降和劣化，如使用陶瓷球的情况。解决方案：与不锈钢或用于内部的轴承钢相比，球3由高速工具钢形成，从而提高了在触地时期望的温度（200-300℃）下的硬度环1或外圈2.因此，防止了球3的发热的早期损坏，并提高了轴承的耐久性。版权所有（C）2006，JPO＆NCIPI
