摘　　要：针对机械原理和机械设计的专业术语,定义了19个概念,如带式链、泵的两个特征、储能块等;修改了25个概念或分类方法,如凸轮、齿轮机构、轮系、键连结、轴和轴承等;使15个概念符合语言学要求,如疲劳磨损所造成的点损、减小载荷波动的改造等。提出了基于啮合力分析的主动斜齿圆柱齿轮所受轴向力方向判断依据。研究成果使该学科的概念更容易被初学者接受。For the technical terms of mechanical principle and mechanical design,19 concepts are defined,such as belt chain,two pump characteristics,energy storage block,etc.,25 concepts or classification are modified,such as cam,gear mechanism,gear train,key connection,shaft and bearing,etc.and 15 concepts meet the linguistic requirements,such as pitting damage caused by fatigue wear,and mechanism remake to reduce the load fluctuation,etc.Based on the meshing force analysis,the judgment basis of axial force direction of active helical gear is put forward.The above research makes the concept more easily accepted by beginners.
