DIN ISO 1977:2014-12

This International Standard describes 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 specified in this International Standard are intended to ensure interchangeability of complete chains and individual links for repair purposes. This document 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. Controls do not necessarily determine sprocket design parameters. Specifications are also given for K attachments and deep plates for use with the conveyor chains conforming to this standard. This document includes the German version of ISO 1977:2006 prepared by Technical Committee ISO/TC 100 "Chains and chain sprockets for power transmission and conveyors". National concerns in the preparation were introduced by Working Committee NA 060-34-35 AA "Stahlgelenkketten" ("Chains") in the department "Antriebstechnik" ("drive technology") at DIN Standards Committee Mechanical Engineering (NAM). Representatives of manufacturers and users of chains, and of employers' liability insurance associations have been involved in the preparation.
