介绍密炼机组主减速机的构造和功能以及使用和维护。减速机为多级齿轮箱,由传动件(齿轮和齿轮轴)、支撑件(轴承)、小件(调整垫圈和闷透盖)、箱体、油路(润滑冷却系统)构成。严格按照规范使用和维护减速机,注重排除齿轮损伤、轴承损坏、断轴、噪声大、渗漏油等问题,对保证减速机正常运行十分重要。 Introduce the construction and function of the main reducer of the mixer as well as its use and maintenance. The reducer is a multi-stage gearbox, which consists of transmission parts (gears and gear shafts), supports (bearings), small parts (adjusting washers and stuffy covers), cabinets and oil passages (lubrication cooling system). In strict accordance with the norms to use and maintain reducer, pay attention to eliminate gear damage, bearing damage, broken shaft, noise, leakage of oil and other issues, to ensure the normal operation of reducer is very important.
