When the two axes of the spur pinion and the bevel gear are orthogonal, the tooth of bevel gear will distribute in a disk, so that it is called generally the face gear drive. With the specificity of the pair of face gear in the split/combination drive of power, it shows its potential advantage in the application of aviation area. At the present, the overseas research and application on face gears have already been in the more depth. Since internationally the face gear drive has been used in the military, it is self-evident that the technique is blockaded on our country. Therefore, the transmission technology of face gear drive must be established in the domestic research and development. The researchs on the face gear drive to increase its transmission performance and meshing quality and reliability are very necessary and important for the public secruity and national defense. In this dissertation the main contents and the conclusions are following as: The researchs on the geometrical principle of face gear drive, the localization of contact bearing and the correction of the tooth flank form have been done. The mathematical model generating face gear using shaping cutter has been established to obtain the theoretical equations of the orthogonal face gear. Based on the generating theory of face gears, the critical conditions of the teeth non-undercutting and non- pointing of face gears have been set up, then the internal radius and outer radius have been determined. Then two pairs of face gears being taken as examples, the calculation of the gear geometric parameter and the blank design have been carried out. The computing formulas of the coordinate grids in the rotary projection of face gear tooth surfaces have been derived, and according to the relationship of rotary projection, the data of theoretical tooth surface have been solved by the numerical alonrithm. Finally, the 3-D simulation of the object model of the theoretical tooth surface has been carried out by using the UG software. The 3-D modelling proves that the above theoretical derivation and the geometric design on the face gears are right. 河南科技大学硕士学位论文 IV The mathematical model of the pair of face gears meshing used in TCA has been set up, and then the contact path of the pair of face gears has been obtained by the sovling of the model. The analysis have been done on the fluences of the three kinds of installing errors on the transmission performance of the orthogonal face gears, refering to the offset errors, the angle errors of deformation and the axial displacement errors. Then based on the analysis results of TCA, the calculation of the contact ratio of the face gear drive has been done. According to meshing theory of the face gear and the spur pinion, the design of the gear shaping fixture has been done, and then the worktable of the present type of 514 gear slotting machine-tool has been rebuilded. Then the tests of the face gear shaping have been carried out, and a serial of pairs of face gears have been slotted. Then noise tests of inspection on a type of Y9550 inspectiong machine-tool have been done. The above tests basically achieving the expected results proves the theoretical researchs in this dissertation.
