摘　　要：带传动是最为典型的摩擦传动,带传动设计在机械设计课程教学中占有重要地位。作者根据多年的教学实践,对带传动设计部分的教学困难和教学目标及内在的教学逻辑进行了思考与总结;按照知识体系的理解顺序,将授课逻辑分为8个部分,并对每个部分的授课方法进行了归纳;对"带传动的受力分析"和"带传动的弹性滑动和打滑"两个较难知识点的授课过程进行了示范性说明,指出了教学过程中的注意事项。相关分析可为机械设计课程中带传动设计部分的教学提供借鉴和参考。Belt driving is a kind of typical drivings.The teaching of the belt driving plays a important role in the course of mechanical design.According to many years’ teaching experience,the authors explain the difficulty and target of teaching for the belt driving,and analyze the teaching logics.Based on the understanding process of the belt driving mechanism,the teaching contents are divided into 8 logics parts,and the teaching method for each part are summarized.The authors also take the two difficult teaching points of "force analysis of belt driving" and "slippage and elastic slippage of belt driving" as examples to analyze the teaching method and point out the matters needing attention when teaching.This paper can provide reference for the course teaching of mechanical design.
