Study on the Tooth modification for High Speed Gear

In this paper, after we make high speed gear requested high precision, we got data on the sound level is Max 60,000rpm for tooth modification. We make a decision about tooth modification after predicting exactly amount of tooth interference by FEM. The purpose of this research is that modified gear is to drive under stable sound level. To accomplish its, Beam elements are used to simulate the same condition as a real gear drive by FEM. From result of simulation and experiment, if it has holes to decrease whole weight of high speed gear, it is not good effect because it has much more deformation than not.
