Abstract
Gear transmission errors cause many problems such as efficiency loss, noise, and some kind of failures. If it can be possible to predict gear transmission errors easily, there are many advantages to improve such problems. A simulation program has been developed for the purpose of estimating gear transmission errors, but there is some difference in results between simulation and experiment. In the simulation, theoretical equation is used to calculate tooth deflections. In this paper, as another approach for prediction of gear transmission errors under load, experimental equations of tooth deflections are used in a newly developed simulation program. Since tooth deflection is one of the main aspects of gear transmission errors, a comparison of two simulations is expected to lead some clues in this problem.
