试验证明 ,陶瓷球轴承是一种性能优良的高速主轴轴承。因使用了陶瓷材料 ,对轴承进行优化设计是发挥其性能的前提。轴承的工作游隙是影响其性能的关键因素之一。陶瓷轴承的游隙选择尚无标准。本文对陶瓷球轴承的工作游隙进行了深入分析和计算 ,为陶瓷轴承游隙的合理选取和修正提供依据。 Test proved that ceramic ball bearings is a high-performance high-performance spindle bearings. Due to the use of ceramic materials, the optimal design of the bearing is a prerequisite for its performance. Bearing work clearance is one of the key factors affecting its performance. There is no standard ceramic bearing clearance choice. In this paper, the ceramic bearing clearance work carried out in-depth analysis and calculation for the clearance of ceramic bearings to provide a reasonable basis for selection and correction.
