【摘要】 本文提出了用测量头的直线运动轨迹做基准来在位检测大齿轮渐开线齿形误差的新方法，建立了在统一坐标系中的齿部理论渐开线数学模型和测量头轨迹方程以及经原理误差补偿后的齿形误差计算模型，解决了定位精度问题。这种新方法特别适用于大齿轮齿形误差在位检测仪器的研制和开发。更多还原

【Abstract】 This paper puts forward a new method for the on-line measurement of large gear’s profile with a straight moving orbit of a pick-up’ being acted as a measuring basis, establishes a theoretical involute mathematical model and a moving orbit’s equation of the pick-up in the same coordinate system, and presents a calculating model after the principal error has been compensated. This new method is especially suitable for developing on-line measuring instruments for large gear’s profile.更多还原
