摘要/Abstract

摘要： 针对内齿轮刮齿加工过程中，由于轴交角误差的存在而影响齿轮加工精度的问题，为了提高刮齿机的加工精度，首先建立了无进给、刀具进给和工件进给三种运动方式下刀具与工件之间的运动学模型；其次，通过分析不同轴交角误差方向下刀具和工件之间的相对运动关系，研究了内齿轮齿廓加工误差的产生机理；然后，通过建立多因素耦合关系模型，分析了不同轴交角误差方向对刮齿加工误差的影响程度，获得了最佳的轴向进给方式和轴交角误差方向；最后，通过样机试切实验验证了理论分析的有效性，样机满足6级加工精度要求。

Abstract: During the internal gear skiving, because the existence of shaft angle error, there would be some deviation in gear precision after machining. For improving the machining accuracy of the gear skiving machine, First，the kinematics model between the cutting tool and the workpiece was established under the three motion mode of non-feed, tool feed and workpiece feed. Second, the relative motion relationship between tool and workpiece was analyzed under different shaft angle error directions. And the mechanism of machining error of internal gear profile was studied. Then, through the establishment of multi-factor coupling model, the influence of different shaft angle error directions on gear skiving error were compared and analyzed, and the optimal axial feeding mode and shaft angle error direction were obtained. Finally, the validity of the theoretical analysis was verified by trial machining experiment of the prototype. And the workpiece after machining met level 6 precision requirement.

Key words: gear skiving machine, internal gear, shaft angle error, multi-factor coupling
