齿轮传动是最主要的机械传动方式,齿轮是机械设备的主要零件之一,同时又是诱发机器故障的重要部位。据国外资料统计,由于齿轮失效引起的机械设备故障约占10.3％。下面就齿轮常见失效形式,相应的维修方法及防止或延缓失效的对策作一介绍。 一、常见失效形式 由于齿轮所在工作环境、润滑条件、材料、热处理方法及制造与安装等多方面因素的影响,齿轮的失效形式多种多样,但常见形式主要为四种:轮齿折断、齿面点蚀、齿面胶合 Gear transmission is the most important mechanical transmission, gear is one of the main parts of machinery and equipment, but also an important part of the induced machine failure. According to foreign statistics, due to gear failure caused mechanical equipment failure accounted for about 10.3%. The following gear common failure forms, the corresponding maintenance methods and to prevent or delay the failure to make an introduction. First, the common form of failure due to the gear where the working environment, lubrication conditions, materials, heat treatment methods and manufacturing and installation of many other factors, the failure of a variety of forms of gear, but the common form is mainly four: broken teeth, teeth Pitting corrosion, tooth surface glued
