GB/T 26090-2010Gear circular pitch measuring instrument (English PDF)

Foreword

The standard proposed by China Machinery Industry Federation. The standard measuring instrument by the National Standardization Technical Committee (SAC/TC132) centralized. This standard is drafted by: Harbin Measuring & Cutting Tool Group Co., Ltd. Participated in the drafting of this Standard. China Institute of Metrology, Beijing Branch in Sunny Ltd. since. The main drafters of this standard. Liu Qingsheng, Sun Xiuwen, Chenxian Min, Zhao, Chen Hongan, Huo Wei. Gear tooth pitch measuring instrument

1 Scope

GB/T 26090-2010 is the Chinese national standard on gear circular pitch measuring instrument, in the field of metrology and measurement. 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 10 January 2011 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 October 2011. Classification: ICS 17.040.30, CCS J42. 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 gear pitch gauge terms and definitions, types and basic parameters, requirements, safety performance, testing conditions, test side France, marking and packaging. This standard applies to gear modulus can be measured in the range of 1mm ~ 20mm, the tip diameter of not more than 600mm of gear tooth pitch measuring instrument (Hereinafter referred to as "pitch meter").
