设计简介
摘 要
本设计是为了方便学生对自由度有更清楚的了解，对于机械原理等基础课程有更深一步的认识。本设计是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，设计的一种自动多功能实验台。它具有五个自由度，其中，有两个转动自由度，三个移动自由度。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，提高学生对自由度的理解，更好地学习和掌握自由度的知识重点，加深对其的理解，真正地做到学以致用。
关键字：实验台；齿轮；轴；轴承
ABSTRACT
This design is to facilitate the students to have a better understanding of degree of freedom and a deeper understanding of the courses such as Mechanic Principle and so on. This design is an automatic and multifunctional experimental platform, in order to improve the design ability, practical ability and innovation ability, according to the modern theory of mechanical principle and structure. It has five degrees of freedom, among them, there are two rotational degrees of freedom, three degrees of freedom of movement. There will be different kinds of related components such as the gears, shafts,bearings and other parts in the process of experiment to make the students make an improvement in understanding the degree of freedom, to learn and master its key knowledge better and to deepen the understanding, therefore they can truly learn in order to practice.
Key Words: Experimental platform;Gear; Shaft,;Bearing
