众所周知,叶片式气动马达是气动工具的主要结构形式之一。叶片式气动马达一般由气缸,转子、叶片、前端盖、后端盖、滚动轴承、定位销等零件组成。其中叶片又是气动马达的主要构件,叶片质量的好坏将直接影响气动马达的功率。叶片的材质有酚醛树脂、尼龙、聚四氟乙烯等。一般采用夹布酚醛树脂(夹布胶木)。酚醛树脂的吸水性很太,受气候条件或贮存条件的影响,叶片长度尺寸变化比较大(吸水膨胀量约0.05～0.30毫米),容易顶住两端盖,使气动马达不能旋转,叶片的工序质量也无法控制。鉴于叶片存在上述问题,对其进行了认真分析和研究。一般气动马达设计时,要求叶片长度与气缸长度的间隙为0.05～0.10毫
As we all know, vane air motor is one of the main structural forms of pneumatic tools. Vane air motor generally by the cylinder, rotor, blades, front cover, rear cover, rolling bearings, pins and other components. Among them, the blade is the main component of the air motor. The quality of the blade will directly affect the power of the air motor. The material of the leaves are phenolic resin, nylon, Teflon and so on. The general use of cloth phenolic resin (cloth bakelite). Phenolic resin water absorption is too much, subject to climatic conditions or storage conditions, the blade length and size changes relatively large (water swelling about 0.05 ~ 0.30 mm), easy to withstand both ends of the cover, so that the air motor can not rotate the blade process Quality can not be controlled either. In view of the above problems leaves, their careful analysis and research. General air motor design, the length of the blade and the cylinder length of the gap between 0.05 ~ 0.10 milliliters
