| Abstract: | The helical gears manufactured by warm compaction powder metallurgy are of good wearability and low cost. This paper first proposes an integrated dynamic model based on the finite element method, in which the gear pair, the transmission shaft, the bearing and the gearbox are all taken into consideration. By using the finite-element analyzing software MSC. Nastran, the vibration response of the transmission system of powder metallurgy helical gear with dynamic excitation is then calculated, and the results are compared with those of 38CrMoAl gear system. Vibration experiments are finally carried out to verify the correctness of the proposed model. By the abovementioned work, a foundation for the design of transmission system with powder metallurgy helical gears is thus laid. |
