齿轮基节的测量是评定齿轮工作平稳性的重要手段之一。根据基节的测量结果,可以计算出齿形角误差和实际基圆半径对其理论尺寸的偏差。在齿轮测量方面,大直径齿轮的临床测量是一个薄弱环节。国内外目前仅能解决周节累积误差的测量,而齿形、齿向的测量尚处于空白。在目前大模数大直径齿轮齿形的测量缺乏仪器的情况下,可以用测量基节来代替。
The measurement of gear base is one of the important means to evaluate the work stability of gear. Based on the results of the measurement of the base section, the deviations of the theoretical angle of the tooth profile angle error and the actual base circle radius can be calculated. In terms of gear measurement, the clinical measurement of large diameter gears is a weak link. At present, only the measurement of cumulative error of the week can be solved at home and abroad, while the measurement of the tooth shape and the tooth direction is still in the blank. In the current large-modulus large-diameter gear tooth shape measurement lack of instruments, you can use the measurement of the base instead.
