摘要： A chain having a plurality of block links each including longitudinally spaced apart ends each of which has a pivot pin receiving first bore therethrough of a first diameter. The chain also has a plurality of connecting links each including longitudinally spaced pivot pins mounted in the block link first bores for articulatively interconnecting the ends of adjacent block links. The pivot pins have a close tolerance fit in the first bores to form a chain that extends along a straight line of travel. The chain further has at least one flight attachment link having a flight attachment support and longitudinally spaced leading and trailing ends pivotally connected between adjacent connecting links of the chain. The leading and trailing ends of the flight attachment link each have a second pivot pin receiving bore of a second diameter sufficiently larger than the pivot pin on which it is mounted to allow only the flight attachment link or links in the chain to cant relative to the chain straight line of travel for automatic self alignment in response to force moments on the flight attachment link to minimize torsional stress imposed on the flight attachment link and its flight attachment support.
摘要翻译：一种具有多个块连杆的链条，每个链节段包括纵向间隔开的端部，每个端部具有枢转销，其接收第一直径的第一孔。链条还具有多个连接链节，每个连接链节包括安装在块连杆第一孔中的纵向间隔开的枢轴销，用于将邻近的块连杆的端部铰接地互连。枢轴销在第一孔中具有紧密公差配合，以形成沿着直线行进延伸的链条。链条还具有至少一个具有飞行附件支撑件的飞行连接连杆，并且纵向间隔开的前端和后端枢转地连接在链条的相邻连接链节之间。飞行连接链节的前端和后端各自具有第二直径的第二枢轴销接收孔，该第二直径足够大于其上安装的枢轴销，其仅允许链中的飞行连接链节相对于链条直线行程，用于响应于飞行附件链节上的力矩自动自对准，以最小化施加在飞行连接链节及其飞行附件支撑上的扭转应力。
