本标准包含铰链式平顶传送链和链轮齿的信息:一系列不同宽度的钢（碳或不锈钢）平面，如本文所述，每侧与铰链状桶构成一体。这些桶被设计成相互交错，以便通过桶形成的孔插入的销连接相邻的链接，从而形成一个连续长度的平顶传送链，可在一个方向上自由弯曲。销通过压配合和/或镦头固定在一个连杆的筒体上，同时与相邻连杆的交错筒体自由配合或滑动配合。这样形成的链条通过链轮齿与卷曲外径啮合来驱动。塑料铰链式平顶传送链与钢制平顶传送链相似，只是链节由塑料材料制成。 销通常由不锈钢制成，可以通过压配合或滚花固定。主要主题是:（a）一般链比例和名称；（b） 链编号系统的说明；（c） 链条尺寸；和（d）链轮齿形-概述。还有以下表格:（a）一般链条尺寸、最小极限抗拉强度和用于检查链条长度的测量载荷；（b） 可互换链环的最大和最小控制尺寸；（c） 链条间隙尺寸；（d） B型齿形链轮正常范围内的标准中径、最大外径和底径以及压力角限制；和（e）链轮齿的最大偏心率和端面跳动公差。

This Standard contains information for Hinge-type Flat-top Conveyor Chains and Sprocket Teeth: A series of steel (carbon or stainless) flat surfaces of various widths as specified herein made integral with hinge-like barrels on each side. These barrels are designed to interlace so that pins inserted through the holes formed by the barrels connect adjacent links, thus forming a continuous length of flat top conveyor chain free to flex in one direction.Pins are retained by press fit and/or heading with respect to the barrels of one link while being a free or slip fit with respect to the interlaced barrels of the adjacent link. The chain so formed is driven by meshing the curl outside diameters with sprocket teeth. Plastic hinge-type flat-top conveyor chains are similar to steel type flat top chains except that the chain links are molded of plastic material. Pins are usually made of stainless steel and may be retained by press fit or knurls.The main topics are:(a) General chain proportions and designations;(b) Explanation of the chain numbering system;(c) Chain dimensions; and(d) Sprocket tooth form – general.There are also Tables for:(a) General chain dimensions, Minimum Ultimate Tensile Strength and Measuring load for checking chain length;(b) Maximum and minimum controlling dimensions for interchangeable links;(c) Chain clearance dimensions;(d) Standard pitch diameter, maximum outside and bottom diameter, and pressure angle limits for normal range of sprocket teeth available with Type B tooth form sprockets; and(e) Maximum eccentricity and face runout tolerances of sprocket teeth.
