| 摘 要： | 为了适应易燃、易爆及防磁的工作环境，该文研制了一种冲击式小型气动马达。介绍了冲击式小型气动马达的工作原理和具体结构组成，理论分析了其喷嘴流量特性和叶轮受力情况，并通过计算机仿真研究了其主要结构参数变化对输出转矩的影响规律。为了对马达输出的转矩和机械功率进行实验研究，设计了一套小型机械特性测试装置。实验研究结果表明：冲击式小型气动马达输出转矩与转速具有良好的线性关系，调速范围广，符合实际应用的要求。

| Abstract: | An impacted mini-air-motor is studied and developed to be applied in the combustible, explosive and antimagnetic conditions. The operating principle and the structure of the mini-air-motor are discussed. The discharge characteristics of the nozzle and the mechanical characteristics of the mini-air-motor are analyzed. The effect of main structure parameters on the output torque of the mini-air-motor is simulated. In order to study the mechanical characteristics of the mini-air-motor, a measurement instrument is designed. The experimental results indicate that the output torque of the motor has good linear relation with the rotational speed, and the range of the speed regulation is very wide. The impacted mini-air-motor is suitable to the application condition. |
