链轮与圆环链链条(以下简称链条)啮合传动的失效与否,直接关系到煤矿刮板输送机的安全运转和工作而的生产效率。根据国内煤矿井下机电事故的统计,刮板输送机的机电事故约占总事故率的60％以上,而刮板输送机事故中,链轮与链条的啮合传动事故又居刮板输送机事故率的首位。因此要使链轮与链条的啮合事故减少,输送机运转良好,对链轮与链条啮合传动的了解很有必要。本文就此问题提出几点看法。一、链轮与链条的啮合作用为分析简单起见,对与链条相啮合的链条,可视为绝对刚体而又是不可磨损的完好
Sprocket and circular chain chain (hereinafter referred to as the chain) meshing transmission failure or not, directly related to coal scraper conveyor safe operation and work efficiency. According to the statistics of mechanical and electrical accidents in domestic coal mines, the mechanical and electrical accidents of scraper conveyors account for more than 60% of the total accident rate. In the accident of scraper conveyors, the meshing transmission accidents of sprocket and chain are also the accidents of scraper conveyors The first place. Therefore, to make the sprocket and the chain to reduce the accidental engagement, the conveyor is running well, the sprocket and chain engagement transmission is necessary. This article put forward some views on this issue. First, the sprocket and the meshing effect of the chain For the sake of simplicity, the chain engaged with the chain, can be considered as an absolute rigid body but also can not wear intact
