渐开线斜齿轮展成加工虚拟实验的设计与实现

Design and Implementation of Virtual Experiments for Involute Helical Gear Generation

展成法是应用最为广泛的齿轮加工方法,其牵扯的运动很多,往往导致学生理解困难。单纯的动画演示教学或现场参观教学无法将刀具与轮坯的运动完整、清晰地展现出来,为此笔者借助虚拟现实技术,设计了渐开线斜齿轮展成加工虚拟实验,让学生亲自动手演示并观察刀具运动、轮坯的运动以及附加运动,并在此基础上了解滚齿机的结构及组成。该实验的教学能够调动学生的学习积极性和主动性,培养学生的实际动手能力,为其学习机械原理等课程奠定良好的基础。

Generation method is the most widely used gear processing method,and its involvement in many movement leads to students’difficulty in understanding.Simply using animation demonstration or on-site visits cannot fully and clearly show the movement of cutter and wheel blank.Therefore,with the help of virtual reality technology,the virtual experiment of involute helical gear generating and processing is designed and realized.Through this experiment,the students can demonstrate and observe the movement of cutter,gear blank and additional movement by themselves.On this basis,they can understand the structure and composition of gear hobbing machine.The experiment can mobilize students’learning enthusiasm and initiative,cultivate students′practical ability,and lay agood foundation for the study of mechanical principles and other related courses.
