| 摘 要： | 陶瓷轴承球的表面缺陷会严重降低球的强度和滚动接触疲劳寿命。针对陶瓷球表面缺陷自动检测要求精度高、可靠性高的特点，建立了基于图像处理的检测方案，并证明了该方案的有效性。为保证表面不漏检,应用螺旋面展开法设计球面展开机构，推导球面展开运动方程，计算转速控制曲线，分析了控制参数对检测系统精度和检测效率的影响，为陶瓷球表面缺陷自动分类和识别提供了可靠方法。

| Abstract: | Surface defects in ceramic bearing bails may significantly affect ball strength and reduce rolling contact fatigue lifetime. A surface inspection system composed of optical microscope, digital imaging system and unfolding mechanism has been developed to provide image data for detecting natural defects on the surface of polished Si3N4 balls. The ball surface unfolding model was constructed with a helicoid unfolding method. According to parameters of the imaging system, unfolding control functions were derived and rotating speed control curves were calculated. The influences of control parameters on inspection accuracy and efficiency were analysed to instruct design of control system. |
