A conical involute gear is an involute gear that external form is cone. The contact between tooth surfaces is the point contact. Therefore, in conical involute gear design, the evaluation of tooth surface strength is more important than bending strength. The evaluation of the strength of the conical involute gear is just entered on a research. The strength design of the conical involute gear has not been established yet. For the evaluation of tooth surface strength, experiments of the fatigue strength is needed. The authors developed a new testing machine for intersecting-axis conical involute gears. Using this testing machine, experiments on fatigue strength are perfomed in this paper. The circulating torque is kept constant and the number of times of contact is 10^7. The tooth surface life is evaluated by pitting area rate. As a result, the allowable load is obtained.
