This document was issued in.1992; when it was revised for the first time in.2008, GB/T 17197-1997 "Belt drive combined with ordinary V-pulley (Effective Width System)" was incorporated; this is the second revision.IntroductionV-belt transmission is one of the most important transmission modes in belt transmission. Ordinary and narrow V-belt transmissions are the most basic forms of V-belt transmission. They are widely used. Used in various fields of general industry (machine tools, mining machinery, petroleum machinery, coal mining machinery, woodworking machinery, garden machinery, etc.). my country as early as.1992 Two national standards, "Belt Drive Ordinary V-Belt Drive" and "Belt Drive Narrow V-Belt Drive" were issued. In.2008, the two national standards The content has been expanded. With the rapid development of digital design, the parametric requirements for belt drive system design are extremely urgent. Therefore, the two national The standard was revised. Ordinary and narrow V-belt drives can be divided into two series, the reference width system and the effective width system. GB/T 13575 aims to refer to The selection and design application of the guide transmission system is proposed to be composed of two parts. --- Part 1.Reference width V-belt drive content. The purpose is to establish the selection suitable for the reference width V-belt drive system and design specifications. --- Part 2.Effective width V-belt drive content. The purpose is to establish the type selection suitable for effective width V-belt transmission system and design specifications. Ordinary and narrow V-belt drives Part 2.Effective width system1 ScopeThis document stipulates the main dimensions of narrow V-belts and pulleys under the effective width system, transmission design, installation and use of transmission devices, etc. This document applies to V-belt drives for general industrial use.2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document.
