Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is Part 1 of GB/T 38205 "Installation Dimensions of Hydraulic Transmission 16MPa Series Single Rod Cylinders".

The following parts have been published.

--- Part 1: Medium series;

--- Part 2: Compact series with cylinder diameter of 25 mm to 220 mm;

--- Part 3: Compact series with cylinder diameters of 250 mm to 500 mm.

This document is modified to adopt ISO 6020-1:2007 "Hydraulic transmission 16MPa (160bar) series single-rod cylinder installation dimensions Part 1 Part. Medium Series.

The technical differences between this document and ISO 6020-1:2007 and their reasons are as follows.

--- The scope of application of the standard has been changed (see Chapter 1) to adapt to my country's technical conditions and improve operability;

--- The normative references GB/T 17446 replace ISO 5598 (see Chapter 3), GB/T 9094 replaces ISO 6099 (see 4.3, Chapter 7), GB/T 2348 replaced ISO 3320 (see Chapter 5), GB/T 2350 replaced ISO 4395 (see 8.2), GB/T 39949.1 replaces ISO 8132 (see 8.3) to adapt to my country's technical conditions and improve operability;

---Added eight cylinder sizes. 90mm, 110mm, 140mm, 180mm, 220mm, 280mm, 360mm, 450mm diameter (see Table 1 to Table 7) to adapt to my country's technical conditions and improve operability;

--- Deleted the provisions of "Installation type code marking" in ISO 6020-1:2007, because its code marking has been specified in Chapter 7;

--- Added requirements for the type and size of piston rod ends (see 8.2) to adapt to my country's technical conditions and improve operability;

--- Deleted ISO 1179-1 oil port "EE" thread tolerance grade "6g" in Table 7 of ISO 6020-1:2007, and replaced ISO 6149-1 oil port "EE" thread tolerance grade "6g" in Table 7 of ISO 6020-1:2007.

The thread tolerance grade "6g" of "EE" in ISO 6164 and ISO 6162-1 was changed to "6H", and the thread tolerance grade "ED" in ISO 6164 and ISO 6162-1 was changed to "6H".

The grade "6g" was changed to "6H" (see Table 7) to adapt to my country's technical conditions and improve operability;

---Changed the piston stroke division range and the corresponding installation size limit deviation (see Table 8) to adapt to my country's technical conditions and improve Operability;

---Changed the piston stroke division range and the corresponding stroke limit deviation (see Table 9) to adapt to my country's technical conditions and improve operability.

Acting nature.

The following editorial changes were made to this document.

--- In order to coordinate with the existing standards, the name of the standard is changed to "Installation Dimensions of Hydraulic Transmission 16MPa Series Single Rod Cylinders Part 1 Divided into. Medium Series";

---The drawing was redrawn according to my country's mechanical engineering drawing standards;

--- Deleted the footnote in Chapter 1;

--- Deleted the "Note" in Figure 1, and added the notes in Figures 3 and 4;

--- Additional information on size selection values is added to Tables 1 to 7;

--- Delete the "Swing angle Z" column in Table 4, and add the paragraph "The minimum swing angle Z is 4°" in Table 4;

--- Added "Units are in millimeters unless otherwise indicated" in the upper right corner of Table 7;

--- Changed the travel range marking method in Table 8 and Table 9.

Introduction

In a hydraulic fluid power system, power is transmitted and controlled by pressurized fluid in a closed circuit.

A hydraulic actuator that converts pressure energy into mechanical energy to achieve linear motion. The moving components include pistons, piston rods, etc.

GB/T 38205 aims to determine the installation dimensions of the 16MPa series single-rod cylinders and is intended to consist of three parts.

--- Part 1: Medium series. The purpose is to determine the installation dimensions of 16MPa series medium single-rod hydraulic cylinders.

--- Part 2: Compact series with cylinder diameters of 25 mm to 220 mm. The purpose is to define the 16 MPa series of compact single-rod hydraulic cylinders (cylinder diameter 25mm~220mm) installation dimensions.

--- Part 3: Compact series with cylinder diameters of 250 mm to 500 mm. The purpose is to determine the 16 MPa series of compact single-rod hydraulic Installation dimensions of cylinder (cylinder diameter 250mm~500mm).
