Aiming at the complexity of its geometric shape and individual error measurement, the detection and analysis of contact spot of high-order bevel gear pair was proposed based on the gear engagement theory and bevel gear detection technique, and the mathematical model of bevel gear cutter＇s tooth surface was also deduced. Then, the influence rules of contact spot of each component force were analyzed according to the force analysis of high-order oval bevel gears. Meanwhile, the influence rules of contact spot of tangential force were mainly discussed, and a new characteristic that the size of contact spot presents a certain periodicity with tangential force was also obtained. Furthermore, the locating distance alteration of oval bevel gear pair was modeled and the influence rules of contact spot of tangential force were also obtained. Meanwhile, the regulation means of this gear pair were summarized. Then, the rolling experiment was performed on the oval bevel gear entities to verify the influence rules of contact spot of tangential force. The contact spots under different locating distances were detected and analyzed at the same time. As a result, the influence rules of contact spots under different locating distances were also verified.
