一、前言齿轮气马达属于容积式马达中的一类。这类气马达由于制造简便,运转时平稳啮合,工作安全可靠,因而在国外获得较广泛应用;但这类气马达与其他种类的气马达相比,其绝热总效率较低,运转中的噪声也较大,往往要附加消声器。齿轮气马达的形式有直齿与斜齿(包括人字齿)两种。本文仅就直齿轮气马达主要参数的设计计算进行讨论。直齿轮马达又分为多转子及双转子两种。按转子彼此啮合的形式直齿轮气马达又有内啮合与外啮合之分。外啮合的双转子直齿轮气马达具有结构简单的优点,
I. INTRODUCTION Gear air motors are a class of positive displacement motors. This type of air motor is widely used in foreign countries because of its simple manufacture, stable meshing during operation, and safe and reliable operation. However, compared with other types of air motors, this type of air motor has a lower overall efficiency of heat insulation and noise during operation. Also large, often add muffler. The gear gas motor has two types of straight teeth and helical teeth (including herringbone teeth). This article only discusses the design and calculation of the main parameters of the straight gear gas motor. Spur gear motor is divided into two kinds of rotors and double rotors. The spur gear gas motors in the form of meshing with each other have internal and external meshing points. Externally meshed double-rotor straight gear air motor has the advantages of simple structure,
