Design of Involute-Cycloid Composite Tooth Profile Spur Gear to Reduce the Influence of Center Distance Error on Driving Performance

The involute-cycloid composite tooth profile gear developed by the authors has some advantages against typical involute gear in tooth bending strength, surface durability, and power transmission efficiency. However, it is expected that the involute-cycloid composite tooth profile gear is sensitive to center distance error since this tooth profile includes cycloid part. In this study, we calculated the tooth root stress and tooth contact stress of involute-cycloid composite tooth profile spur gears with changing center distance and some design parameters which define the tooth profile. Then we have searched design parameters which reduce the influence of center distance error.
