GB/T 17126.1-2009Agricultural tractors and machinery -- Power take-off drive shafts and power input connection -- Part 1: General manufacturing and safety requirements (English PDF)

Foreword

GB/T 17126 "Agricultural tractors and machinery - Power shafts and power - input connection" is divided into.

--- Part 1. General manufacturing and safety requirements;

--- Part 2. PTO shaft using a standard, all types of coupling device output power train and power input connection Device location and clearance range.

This section is GB/T Part of 117,126.

This section identical with ISO 5673-1:2005 "Agricultural tractors and machinery PTO shaft and power input connection means Set Part 1. General manufacturing and safety requirements "(in English).

This section is equivalent translation ISO 5673-1:2005.

For ease of use, this section made the following editorial changes.

--- "This International Standard" be replaced by "this section";

--- Remove ISO 5673-1:2005 Foreword;

--- ISO 5673-1:2005 and other international standards referenced with have been adopted in place for our standards.

This section is amended to GB/T 17126-1997, the main technical content changes are as follows.

--- According to the new international standard will be divided into two parts;

--- Added "two PTO shaft", "two power input connection means" terms and definitions;

--- Increasing manufacturing and safety requirements;

--- Increased use of information requirements.

Date of implementation of this section instead of GB/T 17126-1997 part of.

This part is proposed by China Machinery Industry Federation.

This part of the National Standardization Technical Committee on Agriculture machinery centralized.

This section drafted by. Chinese Academy of Agricultural Mechanization Sciences, Luoyang Tractor Research Institute, the National Quality Supervision and Inspection Center of farm machinery.
