5×26英尺铁板给矿机由美国A.C.公司生产制造,运用于德兴铜矿一期技术改造工程,自1989年初使用以来,其下托轮多次从托轮架上整体脱落,进入84英寸液压圆锥破碎机,给破碎机带来了很大的危害,同时,铁板给矿机的下边失去了支撑,链板直接对机座的加固横梁磨损,严重损害了机座并降低了使用寿命。为此,对其进行了一系列的技术改造。(一)下托轮存在问题及技术改造1.轮体。厂家生产的轮体内径安装一个无内圈滚针轴承,其外径与轮体内径为间隙配合,轮体
5 × 26 feet of iron to the mining machine manufactured by the United States AC company, used in Dexing Copper Mine a technological transformation project, since its use in early 1989, the next round of its overall from the carrier wheel off the whole, into the 84 Inch hydraulic cone crusher, to the crusher has brought great harm, at the same time, the iron plate to the bottom of the mine lost support, the chain plate reinforcement directly to the beam wear, seriously damaging the base and reduce the use of life. To this end, carried out a series of technological transformation. (A) under the wheel of the existing problems and technical transformation 1. Wheel body. Wheel diameter produced by the manufacturer to install a needle roller bearings without inner ring, the outer diameter and the wheel diameter for clearance fit, wheel body
