教学活动中发现部分学生在学习带传动设计时,不太重视系统的理论基础知识的学习,仅满足于按照设计步骤、计算公式完成设计,实践证明往往是失败的。带传动中初拉力的确定,以及带速对传动功率的影响,是特别容易被忽视的问题,本文就此针对性地作了进一步的探索与分析,提出了解决问题的措施。 During the teaching activities, some students found that when they studied the drive design, they did not pay much attention to the study of the theoretical basic knowledge of the system. They only satisfied that the design was completed according to the design steps and formulas, and the practice proved to be a failure. The determination of initial pulling force of belt drive and the influence of belt speed on driving power are the problems that are particularly overlooked. In this paper, we make further exploration and analysis in this regard, and put forward some measures to solve the problem.
