| Abstract: | The structure and transmission principle of filtering gear reducer was briefly introduced,the reasons for tooth profile modification of filtering gear reducer were analyzed,and then the method suitable for engineering was adopted to calculate the modification amount,curve and length of the prototype.Dynamic contact finite element analysis on meshing process before and after tooth profile modification was carried out,the effect of tooth profile modification was verified by comparing the changes in tooth surface contact stress before and after tooth profile modification.At last the vibration test of prototype is performed to validate that the tooth profile modification can reduce noise and vibration. |
