空间轮系综合实验台的设计

摘要：
本设计是为了方便学生对轮系有更清楚地了解，对于机械原理等基础课程有更深一步的认识，因此作为传统的轮系实验台，我们很难将其内部结构清楚地展示。尤其作为教学用轮系结构，由于轮系本身有很多类型，而不同类型结构的差异也很大，尤其是周转轮系和复合轮系结构的特殊性，如果仅就平面图形观察，很难从实质上理解其运动形式，容易在轮系传动比计算或其运动分析过程中产生困惑，而且传统的实验台大都为平面轮系，不能让学生了解空间轮系的结构和运动形式。因此本设计按照现代机械原理和结构理论，以提高设计思维能力、动手能力、创新能力为出发点，设计的一种实验用综合轮系实验台。在实验过程中，会为学生提供不同的齿轮、轴、轴承等相关零件，学生可以根据自己所学知识，按照自己的设计来组装轮系实验台，通过这样的方法来提高对空间轮系的理解，更好的学习和掌握空间轮系的知识重点，加深对其的理解，真正的做到学以致用。

The design of the spatial
gear train synthesizes the laboratory bench
Abstract: This design is to facilitate the student to have to the gear train understood clearly that regarding core curricula and so on mechanism has a deeper step understanding, therefore as the traditional gear train laboratory bench, we demonstrated clearly very difficultly its internal structure. Especially as teaching with gear train structure, Especially as teaching with gear train structure, but the different type structure's difference is also very big, particularly epicyclic train and compound gear train structure particularity, if only on the plane figure observation, if only on the plane figure observation, easily produces puzzled in the gear train velocity ratio computation or in its movement parsing process, moreover the traditional laboratory bench is the plane gear train mostly, cannot let the student understand the spatial gear train the structure and the movement form. Therefore this design according to the modern mechanism and the structural theory, take sharpens the design power of thought that beginning ability, innovation ability as the starting point, will provide the different gear, the axis, the bearing for the student and so on related components, the student may act according to itself to study the knowledge, will assemble the gear train laboratory bench according to own design, will enhance through such method to the spatial gear train understanding, a better study and will grasp the spatial gear train the knowledge key point, will deepen to its understanding, true will achieve studies for the purpose of application.
