在链节设计中,起初,由于载荷和速度对无声链的要求并不突出,所以没有过多的注意应力集中和衰减的问题,致使链传动中的不连续性进一步明显,在销孔凹穴处和链节体中产生高的应力。更有甚者,如果链节线落到链轮节线之下,其结果导致链在啮合时的上下运动,这就使得它在高速运行对产生强烈的振动。近年来,对链节的设计作了改进以增加载荷和速度容量。首先,在销孔凹穴处和链节体上增加了材料,并且把各元角处作得圆滑以提高强度和减少应力集中。同时,把链节线抬高
In the design of the chain link, at first, due to the unobtrusive requirement of the silent chain due to the load and speed, there is not too much attention to the problem of stress concentration and attenuation, which leads to the further obvious discontinuity in the chain drive. Department and the link body to produce high stress. What is more, if the link line falls below the pitch line of the chain, the result is an up-and-down movement of the chain when engaged, which causes it to vibrate strongly at high speeds. In recent years, the design of the link has been improved to increase the load and speed capacity. First, materials are added to pin holes and links, and the corners are rounded to increase strength and reduce stress concentration. At the same time, the link uplift
