一、前言冶金、矿山、水泥等行业,经常使用大型减速器、大轴轴承等低速重载设备。此类设备工作环境都较恶劣,温度高、粉尘大、冲击突加载荷多,一般使用寿命都不长。生产厂家为延长其使用周期,从设计、工艺、材料等方面下了很大功夫,因受基础工业和客观条件限制,收效甚微。近年,我们从润滑系统入手,采用硫磷型中极压齿轮油(简称 N220),提高了此类设备的使用寿命,取得了良好的效果。经
First, the foreword Metallurgy, mining, cement and other industries, often using large reducer, large shaft bearings and other low-speed heavy equipment. Such equipment are harsh working environment, high temperature, dust, sudden impact load increases, the general service life is not long. Manufacturers to extend its life cycle, from the design, technology, materials, etc. under a lot of effort, due to the basic industries and objective conditions, with little success. In recent years, we start from the lubrication system, the use of paraquat in extreme pressure gear oil (referred to as N220), improve the service life of such equipment, and achieved good results. through
