ISO 1977:2006规定了用于一般输送和机械搬运的实心和空心轴承销类型的衬套、平滚子链和法兰滚子链的特性，以及相关的链轮和附件。其规定的链条尺寸将确保整个链条和单个链环的互换性，以便于维修。适用于6至40齿的链轮。链轮的控制标准旨在确保在正常运行条件下正确啮合、运行和负载传输。还提供了与符合性输送链一起使用的K型附件和深板的规格。

ISO 1977:2006 specifies the characteristics of bush, plain and flanged roller chains of both solid and hollow bearing pin types designed for general conveying and mechanical handling duties, together with associated chain sprockets and attachments. The chain dimensions it specifies will ensure interchangeability of complete chains and individual links for repair purposes. It is applicable to sprockets with from 6 to 40 teeth. Control criteria for sprockets are defined to ensure correct meshing, operation and transmission of load in use under normal operating conditions. Specifications are also given for K attachments and deep plates for use with the conformant conveyor chains.
