Abstract
In previous studies, we have developed an involute-cycloid composite tooth profile gear, and proved that the gear has larger bending strength, greater surface durability, and higher power transmission efficiency than involute gear. However, wear resistance of the involute-cycloid composite tooth profile gear has not been clarified yet. Therefore, we investigated wear of the gears using a power circulating-type gear testing machine. In the experiments, we measured wear depth and tooth profile error for the involute-cycloid composite tooth profile gear and the involute gear Moreover, we developed a program to calculate the wear of these gears. Then we compared the experimental data with the calculation results. It is concluded that the involute-cycloid composite tooth profile gear has greater wear resistance than involute gear, and the calculation results are in agreement with the experimental data.
