GB/T 18183-2017Fatigue test method for automotive synchronous belt (English PDF)

Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009. This Standard replaced GB/T 18183-2000 Automotive Synchronous Belt Industry - Fatigue Test. Compared with GB/T 18183-2000, this Standard has the major technical changes as follows besides the editorial modifications.

--- Increase the ZH, YH, ZR, YR, ZS, YS, RU, YU, and other models of automotive synchronous belt; and provide the corresponding technical parameters;

--- Increase the technical parameters of tension wheel (see Table 3);

--- Increase the test belt size (see Clause 5);

--- Increase the requirements for automotive synchronous belt high-temperature fatigue test and water-dropping fatigue test, and specify the test (see Clause 6 and Clause 7);

--- Increase the test items in the test report (see Clause 8);

--- Delete the two-wheel fatigue test method of automotive synchronous belt in Appendix A. This Standard was proposed by China Machinery Industry Federation. This Standard shall be under the jurisdiction of National Technical Committee for Standardization of Pulleys and Belts (SAC/TC 428). Drafting organizations of this Standard. Ningbo Yujiang Special Rubber Belt Co., Ltd., Chinese Mechanical Academy of Science, Changchun University, China Wuxi Belt Co., Ltd., Hubei Maoxin Special Rubber Belts Co., Ltd., Ningbo Fengmao Far-east Rubber Co., Ltd., Ningbo Fulong Synchronous Belt Co., Ltd., Ningbo Jiebao Group Co., Ltd., Jiangsu Mingzhu Testing Machine Co., Ltd., and Zhejiang Sunte Technology Co., Ltd.

1 Scope

GB/T 18183-2017 is the Chinese national standard on fatigue test method for automotive synchronous belt, in the field of mechanical systems and components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 12 May 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2017. Classification: ICS 21.220.10, CCS J18. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Standard specifies the fatigue life method of automotive synchronous belt inspected in the laboratory. This Standard is applicable to the ZA, ZB, ZH, YH, ZR, YR, ZS, YS, RU, YU and other models of automotive synchronous belts (hereinafter referred to as synchronous belt).

3 Method Summary

This Standard specifies the fatigue life of automotive synchronous belt inspected by the three-wheel fatigue tester. Fatigue life refers to the number of hours that the synchronous belt has been continuously operated under the conditions specified in this Standard until the specified operating hours have elapsed or any failure mode has occurred. During the test period, the drive wheel operates as per the specified speed, while exert certain torque onto the driven wheel. The tension force is applied to the test synchronous belt through the tensioning wheel of the tensioning device; the tensioning wheel position shall be locked during the testing period.
