According to the traditional inspection method tor straight beret gear's tooth shape error based on the contact moulage exists detects of difficult qnantitative description of geometric errors and poor traceability vector-valued, a kind of tooth shape error measurement and evaluation method of straight bevel gear based on electrical generating is presented Firstly the theory tooth shape of straight bevel gear and mathematical mogel of tooth shape crror measurement is established, then sensor in space scanning straight bevel gear's tooth shape and forming theory curve on the gear measurement center is controlled based on the olosed-loop AC servo control system tooth shape error of straight bevel gear is measured and evaluated based on the sensor readings in the process of continuous scanning Experiment results show that, this method can realize the automatic measurement and evaluation of straight bevel gear's tooth shape error in existing CNC gear neasurenment center, and has significant advantage of the measurement eficiency, high degree of automation, and goad vector-valued traceability.%针对传统基于接触印痕检验的直齿锥齿轮齿形误差检测方法存在的难以定量描述几何误差、量值溯源性差等缺点,提出一种基于电子展成原理的直齿锥齿轮齿形误差测量与评定方法,首先建立了直齿锥齿轮的理论齿形及齿形误差测量的数学模型,然后在基于全闭环交流伺服控制系统的齿轮测量中心上,控制传感器测头在空间扫描形成直齿锥齿轮的理论齿形曲线,依据连续扫描过程中的传感器读数对直齿锥齿轮的齿形误差进行测量与评定.结果表明,该方法可在现有CNC齿轮测量中心上实现直齿锥齿轮齿形误差的自动测量与评定,具有测量效率与自动化程度高、量值溯源性好等显著优点.
