影响风动工具性能的因素很多,如产品结构、型式、设计参数、制造精度、与密气性有关的配合间隙(以下简称间隙)、工作气压、轴压力等。本文仅就间隙对风动工具性能的影响作一些论述。大量的实验证明,即便产品有优良的设计结构和参数,若缺乏合 There are many factors that affect the performance of pneumatic tools, such as the product structure, type, design parameters, manufacturing accuracy, and associated clearances (hereinafter referred to as gaps), working pressure, and axial pressure. This article only discusses the effect of clearance on the performance of pneumatic tools. A large number of experiments have proved that even if the product has a good design structure and parameters, if there is a lack of
