摘要
根据全国部分城市调研资料显示,随着社会进步和社会节奏的加快,教师职业病率呈逐年上升的趋势,职业病呈现多样化方向发展,其中粉尘引起的尘肺以及各种急慢性呼吸道疾病是中国目前职业病中最主要,危害最严重和最广泛的一种。学生近视患病率亦逐年上升,到了异常严重的程度。
本文的设计思路电机通过采用自动送料螺杆的原则驱动,同时对设计方案进行了包括其机构组成和某些重要结构在内的具体设计。该机构介绍派生关系橡皮擦运动形式和结构参数的工作原理。
该分析机构对研究黑板擦的运动规律具有重要意义。该黑板擦由外壳、减速器、齿轮、轴、轴承、毛毡等组成,黑板擦边缘采用密封装置,外接吸尘管。本文所设计的黑板擦具有收尘效率高,结构简单,清灰方便,成本低,可靠性高等特点。

ABSTRACT
According to the National Survey data show that part of the city , along with social progress and social rhythm accelerated rate of occupational teachers showed an increasing trend in the direction of occupational diversified development, including pneumoconiosis and a variety of acute and chronic respiratory diseases caused by dust is China's occupational most important , the most serious and widespread harm one . Students prevalence of myopia has increased year by year , to the unusually severe degree.
In this paper, the design ideas of the motor by using the principle of automatic feeding screw driver , while the design of programs , including position and structure of their bodies , including some important specific design . The agency describes the relationship between the eraser works derived form of exercise and structural parameters .
This analysis has important implications for research institutions eraser law of motion .
