目前我国煤矿使用的固定式天轮,主要由铸铁和铸钢两种材料加工而成,且绝大部分安装在高高的井架上,起吊安装和维护修理很不方便。由于钢丝绳与天轮绳槽是直接滚动摩擦,并承受较大的协载荷,绞车提升量大,运转时间长,钢丝绳给天轮造成的磨损比较严重铸铁天轮的磨损尤甚。一般情况下,天轮的其它部位尚完好,而轮缘绳槽已磨损超限,只得报废再更换新的。1992年7 月,华亭矿务局东峡煤矿对主井绞车副绳磨损超限报废的固定式铸铁天轮,在轮缘绳槽内镶填MC尼龙块,并用环氧树指粘接后断续使用,效果良好。1.方法(1)尼龙衬块的制作。由于 MC尼龙必须在 150℃的高温下冷却凝固,经模拟试

At present, the fixed sheave used in coal mines in our country is mainly made of two materials of cast iron and cast steel, and most of them are installed on tall derricks. It is not convenient for hoisting, installation, maintenance and repair. Due to the direct rolling friction of the rope and the sheave rope groove, and to bear a larger load, winch lift large, long running time, wire rope to the wheel caused by the wear and tear more serious cast iron wheel wear especially. Under normal circumstances, the other parts of the celestial wheel is still intact, and the flange of the rope groove has worn over, had to scrap and then replace the new. July 1992, Huating Mining Bureau of Dongxia Coal Mine on the main shaft winch wear out of limit fixed cast iron cast iron wheels, inlaid in the rim rope groove filled with MC nylon block, and with epoxy refers to the bond after the break Continued use, good effect. 1. Method (1) nylon pad production. As MC nylon must be cooled and solidified at a high temperature of 150 ℃, the simulation test
