Introduction

V-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 transmission system design are extremely urgent. Therefore, the two The national standard has been revised. Ordinary and narrow V-belt drives can be divided into two series, the standard width system and the effective width system. GB/T 13575 aims at In guiding the selection and design of the transmission system, it 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 1.Datum width system

1 Scope

This document specifies the main dimensions, transmission design and installation and use of ordinary and narrow V-belts and pulleys under the reference width system and so on. This document applies to V-belt drives for general industrial use.
