Non-contact measurement bearing sphere geometry parameter apparatus

A non-contact measurement bearing sphere geometry parameter apparatus comprises two optical displacement sensors. The two optical displacement sensors are oppositely arranged and are located on a same measurement plane. Optical shafts of the two optical displacement sensors are located at a same axis. A bearing sphere to be measured is placed on a rotating shaft along an optical axis direction vertical to two optical sensors. A center of the rotation shaft is provided with an air hole. The air hole is connected to a vacuum pump. The rotation shaft is linked to an output shaft of a driving motor. A measuring plane and a meridian plane of the measured bearing sphere are in a same plane. The invention provides the non-contact measurement bearing sphere geometry parameter apparatus. By using the apparatus, measurement precision is high and a speed is fast. 种非接触式测量轴承球体几何参数的装置，包括两个光学位移传感器，两个光学位移传感器相对设置且位于同个测量平面上，两个光学位移传感器的光轴位于同轴线上，被测轴承球体放置在个可沿垂直于两个光学传感器的光轴方向的转轴上，该旋转轴的中心有个气孔，该气孔与个真空泵相连接，所述转轴与驱动电机的输出轴联动，所述测量平面与被测轴承球体
