The contacting situation between tooth surface of crossed helical gears in engagement is geometricaly a point contact. Due to high contact pressure on the tooth contacting surfaces caused by point contact and further high sliding velocity of crossed helical gears, the load carrying capacity of crossed helical gears is very low. On the other hand, crossed helical gears have many important advantages, i. e., they are easy to produce and their engagement is not influenced by mounting errors, e.g., center distance error and shaft angle error. We carried out studies on the influence of tooth profile and tooth surface treatment as well as of lubricating oil on load carrying characteristics of crossed helical gears. In this study we found some ways to improve the load carrying capacity of crossed helical gears.
