圆环链经恶劣工况使用后磨损情况,是导致缩短链条和链轮的使用寿命,是造成生产事故多,生产成本提高的原因之一.通过链轮和链环理论配合试验以及光弹试验法补充,设计了GR链窝链轮,接着对改进设计的直链窝形链轮和链条运行情况进行试验台试验.图1为直链轮基本特征及其同半球链轮的比较.首先图1b示出当链环圆弧半径处于公差下限时,链环接触链窝,典型的挤扁特征就是这一结
It is one of the reasons causing more production accidents and higher production cost because of the wear and tear of the circular chain after being used under harsh conditions, which leads to shortening the service life of the chain and the sprocket. Through the theoretical cooperation test of the sprocket and the chain and the photoelastic test Method to complement the design of the GR chain sprocket, and then to improve the design of the straight chain sprockets and chain run test bench test Figure 1 shows the basic characteristics of straight sprocket and the hemispherical sprocket comparison. 1b shows that when the radius of the circular arc of the link is at the lower limit of tolerance, the link contacts the labyrinth, and the typical crushing feature is this knot
