对机械设计课程中齿轮设计计算教学进行初步探索,通过对繁杂公式的形象说明和准确运用,让学生切实掌握参数的选取方法,并使理论与实践相结合,从而取得了明显教学效果。 This paper first explores the teaching of gear design and calculation in the course of mechanical design. Through the explanation and accurate application of the complicated formulas, students can grasp the method of parameter selection and make the combination of theory and practice, so as to obtain obvious teaching effects.
