Tooth alignment error and tooth profile error of pit bionic large gear before test

In order to make it more convenient and intuitive to compare the measurement data of smooth big gear and pit big gear, the pit big gear also adopts full tooth measurement.

The changes of morphological parameters of each tooth before and after the test are analyzed in detail. Every four teeth are grouped into a group, and the tooth direction error and tooth profile error of the 1st-24th teeth are measured respectively. (A-F) in Fig. 4-5 is the error diagram of 1-24 tooth directions respectively, (G-L) is the error diagram of each tooth profile; The four curves on the left in each drawing are the tooth direction error line and tooth profile error line on the right side of each tooth, and the four curves on the right are the tooth direction error line and tooth profile error line on the left side of each tooth; The error value of each tooth is shown in the lower part of the figure.
