Experimental Investigation of Sprocket Tooth Form Effect on Dynamic Tension of Silent Chain

The study's aim was to get ANSI sprocket tooth profile and involute sprocket tooth profile for effects on dynamic tension of chains in the silent chain drive, and analyse and compare the advantages and disadvantages of the different tooth profiles to choose more practical tooth profile from the two sprockets. Current collector was used to test the dynamic tension when straight sprocket and involute sprocket engaged with the same silent chain. And experimental data measured were analyzed in the amplitude domain and frequency domain. Test results indicate that the probability of tension appearing in the different numerical size and power spectral densities of load in the different frequencies of the involute tooth form are better than of straight tooth form, which show that the involute sprocket has been good working properties. In addition, taking the advantages of involute tooth profile into account in the process, the involute tooth form is recommended in universal sprocket tooth form of the actual use.
