内容简介：
齿轮传动是机械设备中最常见的传动方式，现代机械对齿轮传动的要求日益提高，即要求齿轮能在高速、重载、特殊介质等恶劣环境条件下工作，又要求齿轮装置具有较高的平稳性、高可靠性和结构紧凑等良好的工作性能，由此使得齿轮发生故障的因素越来越多，而齿轮异常又是诱发机器故障的重要因素。因此，齿轮故障诊断技术的应用研究是非常重要的。
齿轮由于制造、操作、维护以及齿轮材料、热处理、运行状态等因素不同，产生异常的形式也不同，齿轮常见的故障形式有如下几种：......
Machinery and equipment in the gear transmission is the most common transmission mode,and the increasing demand gear of the modern machinery .The gear is not only required in high-speed, heavy, special media, and work in other harsh environmental conditions, but also required a high stable , high reliability and compact structure, good performance, so arouse more and more factors of failure. The gear fault is an important factor in inducing mechanical fault.Therefore, the gear fault diagnosis technology research is very important.
Gear because of different factors such as manufacturing, operation, maintenance and gear material, heat treatment,running state and so on , will produce different of abnormal forms.The common faults in gear have the following categories:......
