Based on analysis of the meshing mechanism of a new round-pin jointed silent chain with inner meshing mechanism,the a mathematic model of the inner meshing mechanism silent chain meshing with different stage was developed based on the coordinate transformation theory.The meshing track of the inner meshing mechanism silent chain was obtained by least-squares fitting,and the motion trail and fluctuation quantity of the chain＇s tight side between the new inner meshing silent chain and the traditional outer meshing silent chain were compared and analyzed.The experimental results on a high-speed bench and the calculation results show that the characteristics of the new inner meshing mechanism silent chain include little vibration,low noise,smooth transportation,good wear resistance etc.
