摘　　要：齿轮传动具有传动效率高、传动比恒定、功率和速度适用范围广等优点,在工业产品中广泛应用。齿轮的精度直接影响到工业产品的品质。目前齿轮参数的测量主要采用三坐标测量仪、CNC齿轮测量中心等接触式测量方法。这些接触式测量设备的使用和维修成本均较高,不便于大范围推广。基于机器视觉技术的非接触测量方法,具有实时、高效以及不损害齿面等优点,且随着摄像设备不断改进发展,测量精度大大提高。将机器视觉技术用于齿轮的测量中,提出了一种非接触式的标准圆柱齿轮参数检测方法,对齿轮的几何参数和部分单项误差进行了测量。Gear transmission has the advantages of high transmission efficiency,constant transmission ration,a w ide range of pow er and speed. Gear is w idely used in industrial products. The accuracy of gear directly affects the quality of industrial products. At present,the gear parameter measurement mainly uses the contact type. The current measurement of gear parameters includes coordinate measuring instrument,CNC gear measuring center and so on. How ever,these detection equipment is expensive,and difficult to use and maintenance. They have not been w idely used. The non-contact measurement method based on machine vision technology has the advantages of high efficiency,good real-time,w ide dynamic range and no damage to gear. With the continuous improvement of the camera equipment,the measurement accuracy is greatly improved. In this paper,the machine vision technology is applied to the measurement of gears. A non-contact method for measuring the parameters of standard cylindrical gears is proposed. The geometrical parameters and some individual errors of the gears are measured.
