Manufacturing Method of Pinion Member of Large-Sized Skew Bevel Gears Using Multi-Axis Control and Multi-Tasking Machine Tool Authors: I. Tsuji, K. Kawasaki, H. Gunbara, H. Houjyou, S. Matsumura
In this paper, a manufacturing method of the pinion member of largesized skew bevel gears using multiaxis control and multitasking machine tool considering that the gear member is provided is proposed. First, the tooth surface forms of skew bevel gears are modeled. Next, the real tooth surfaces of the gear member are measured using a coordinate measuring machine and the deviations between the real and theoretical tooth surface forms are formalized using the measured coordinates. It is possible to analyze the tooth contact pattern of the skew bevel gears with consideration of the deviations of the real and theoretical tooth surface forms expressing the deviations as polynomial equations. Moreover, the deviations of the tooth surface form of the gear member are fed back to the analysis of the tooth contact pattern and transmission errors, and the tooth surface form of the pinion member that has a good performance mating with the gear member. Finally, the pinion member is manufactured by a swarf cutting using multiaxis control and multitasking machine tool. Afterward, the real tooth surfaces of the manufactured pinion member were measured using a coordinate measuring machine and the tooth surface form errors were detected. As a result, although the tooth surface form errors were large relatively on the heel side, those were small on the other side. In addition, the tooth contact pattern of the manufactured pinion member and provided gear member was compared with those of tooth contact analysis. As a result, there was good agreement.
