GB/T 8350-2003 in English

《GB/T 8350-2003输送链、附件和链轮》由TC164（全国链传动标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准规定了用于一般输送和机械化传送用实心和空心销轴套筒链、平滚子链、带边滚子链条以及与这些链条相配的链轮和附件的技术特性。标准中规定的链条尺寸将保证链条和用于维修目的的链节的互换性。本标准适用于链轮的轮齿从6～40齿。对链轮的要求是为保证与链条的正确啮合，操作平稳以及在正常的使用条件下传递负荷。

Scope

This standard specifies the technical characteristics of solid and hollow pin bush chains, flat roller chains, side roller chains, and sprockets and accessories suitable for these chains for general conveying and mechanized transmission. The chain dimensions specified in the standard will guarantee the interchangeability of chains and links for repair purposes. This standard applies to sprockets with teeth ranging from 6 to 40 teeth. The requirements for the sprocket are to ensure proper meshing with the chain, smooth operation and load transfer under normal conditions of use. Note: The control conditions do not necessarily determine the design parameters of the sprocket. The standard also stipulates the size of K-type accessories and heightened chain plates.
