Two types of rolling-contact fatigue test machines for ceramic bearings were constructed to investigate the rolling-contact fatique properties of ceramics at elevated temperature in air and vacuum atmospheres. An automatic measuring system of weared shape and wear volume was also constructed to investigate the rolling-contact wear process.The rolling-contact fatigue lives of ceramic bearings at room temperature were around 10^6 cycles when the maximum hertz stress was 2.7GPa, which was longer than that of ordinary metallic bearings. At a temperature of 500゜C, the rolling-contact lives of the ceramics were almost equal to or one-tenth of those at room temperature.From the wear volume measurments, the wear volume per one cycle increased with increasing the maximum Hertz stress and test temperature. This tendency corresponded to the reduction in rolling-contact fatigue life. Wear damages gracually progressed with cycling.The rolling-contact fatigue tests in a clean vacuum of 10^<-7> Torr and upto a temperature of 1600゜C can be done using the rolling-contact fatigue test machine made in the present study.

建立了两种陶瓷轴承滚动接触疲劳试验机，研究了陶瓷在高温空气和真空气氛中的滚动接触疲劳性能。建立了磨损形态和磨损量的自动测量系统，研究了陶瓷轴承的滚动接触磨损过程，在最大赫兹应力为2.7 GPa时，陶瓷轴承的室温滚动接触疲劳寿命约为106次，比普通金属轴承的滚动接触疲劳寿命长。在500゜C温度下，陶瓷的滚动接触寿命几乎等于或相当于室温下的十分之一。从磨损量测量来看，每一周的磨损量随着最大赫兹应力和试验温度的增加而增加。这一趋势与滚动接触疲劳寿命的降低相对应。磨损损伤是随着循环而缓慢发展的。使用本文研制的滚动接触疲劳试验机，可以在10℃~(-7)Torr的清洁真空中和1600゜C的温度下进行滚动接触疲劳试验。
