本文从对破碎机主轴磨损情况的考查,对锥衬套上压力分布的理论证明、对直衬套测试的结果和对缩短的锥衬套的偶然实践等四个方面,详细论述了将圆锥锥衬套尺寸缩短的可能性,并对锥衬套进行了比压和承载能力的验算。最后还指出缩短锥衬套的工业试验办法。 In this paper, the main shaft wear of the crusher test, the pressure distribution on the cone bushing theory to prove that the straight bushing test results and the occasional shortening of the tapered bushing practice in four aspects, discussed in detail the conical cone The possibility of shortening the size of the bushing and the checking of the specific pressure and the carrying capacity of the bushing. Finally, also pointed out that shorten the industrial test methods cone bushing.
