Introduction

V-belt transmission is one of the important transmission methods in belt transmission: Ordinary and narrow V-belt transmission are the most basic forms of V-belt transmission: Ordinary and narrow V-belt transmission can be divided into two series: standard width system and effective width system: It is widely used in machine tools, mining machinery, petroleum machinery, coal mining machinery, woodworking machinery, etc: Industrial machinery, garden machinery, agricultural machinery and other fields: As early as 1989, my country issued GB 11356-1989 "General and narrow V-belt transmission "Pulley Groove Inspection" was revised in:1997 and was revised into two parts of the standard based on the procurement standards---GB/T 11356:1-1997 "Belt Transmission Pulleys for ordinary and narrow V-belt drives (standard width system) Groove inspection" and GB/T 11356:2-1997 "Belt drives for ordinary and narrow V-belts" Belt drive pulley (effective width system) groove inspection", in:2008 completed GB/T 11356:1-2008 "Belt drive V pulley (base width) System) Groove Inspection" revision work: GB/T 11356 is designed to guide the groove shape inspection of ordinary and narrow V-pulleys, and detect their consistency with the standard pulley groove shape through mechanical methods: properties, but no rapid or continuous inspection methods for controlling the geometries of pulley products are specified: GB/T 11356 is intended to consist of two parts: ---Part 1: Base width system: The purpose is to establish groove inspection specifications applicable to standard width V-pulleys: ---Part 2: Effective width system: The purpose is to establish groove inspection specifications suitable for effective width V-pulleys: Belt drive ordinary and narrow V pulley groove inspection Part 2: Effective width system

1 Scope

This document specifies the routine inspection method for the groove shape of V-pulleys with narrow effective width: This document is applicable to the inspection of basic dimensional parameters of narrow V-belt pulleys (effective width system): The corresponding V-belts can be single or combined belts:

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document: GB/T 6931:1 Belt drive terminology Part 1: Basic terminology GB/T 6931:2 Belt drive terminology Part 2: V-belt and poly-V belt drive (GB/T 6931:2-2020, ISO 1081: 2013,MOD) GB/T 10413 Narrow V-belt pulley (effective width system) (GB/T 10413-2002, ISO 5290:2001, MOD)

3 Terms and definitions

The terms and definitions defined in GB/T 6931:1 and GB/T 6931:2 apply to this document:

4 basic procedures

The inspection of pulleys should be carried out according to the following four continuous inspection procedures: a) Groove cross-section inspection; b) Groove spacing inspection; c) Effective diameter inspection; d) Circular runout inspection: 5 Groove cross-section inspection 5:1 Groove cross-section dimensions The groove cross-section size should comply with the regulations of GB/T 10413: The actual outer diameter of the pulley should not be greater than de 2δh1, and the outermost end of the straight edge of the pulley groove should be straight: The minimum diameter is de-2δh2: The test parameters are shown in Figure 1 and Table 1: ......
