The work of preparing International Standards i

7、s normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take par

8、t in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to p

9、repare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility tha

ISO 13726 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 3, Cylinders. This second edition cancels and r

11、eplaces the first edition (ISO 13726:1998), which has been technically revised. BS ISO 13726:2008iv Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. One component of such systems is the fluid power cylinder

12、. This is a device that converts power into linear mechanical force and motion. It consists of a movable element, i.e. a piston and piston rod, operating within a cylindrical bore. BS ISO 13726:20081Hydraulic fluid power Single rod cylinders, 16 MPa (160 bar) compact series with bores from 250 mm to

13、 500 mm Accessory mounting dimensions 1 Scope This International Standard specifies the mounting dimensions required for interchangeability of accessories for 16 MPa (160 bar) compact cylinders conforming to ISO 6020-3. The accessories have been designed specifically for use with cylinders manufactu

14、red in accordance with ISO 6020-3, but this does not limit their application. This International Standard covers the following accessories: AP2 rod clevis, female thread (see Figure 1 and Table 1); AP4 rod eye, plain, female thread (see Figure 2 and Table 2); AA4 - L pivot pin (locking plate) (see F

15、igure 3 and Table 3); AL6 locking plate for pivot pin (see Figure 4 and Table 4); AA4 - S pivot pin plain (see Figure 5 and Table 5). These accessories are used on hydraulic cylinders for mechanically transmitting the cylinder force. The design of these accessories is based on the maximum forces res

16、ulting from the specified internal diameters of the cylinders and pressures according to ISO 2944 and ISO 3320. 2 Normative references The following referenced documents are indispensable for the application of this document.

20、e mounting dimensions for accessories are shown in Figures 1 to 5 and given in Tables 1 to 5. 4.2 For rod eyes with spherical bearing, use those specified in ISO 8132. 5 Material load capacity All cross-sections shall be selected so that, under the maximum tensile load produced by the cylinder, the

21、yield strength of the material used for the accessories is at least 2,5 times the maximum tensile load. 6 Application instructions 6.1 Installation 6.1.1 A tolerance of f8 is recommended for plain bearing pins (see ISO 286-2). 6.1.2 The rod clevis and the rod eye shall be screwed firmly against the

22、piston rod shoulder before locking. 6.2 Lubrication 6.2.1 Sufficient lubrication for the satisfactory performance of these accessories shall be provided. 6.2.2 The method and frequency of such lubrication depends on the particular operating conditions. 7 Example of ordering designation A plain rod e
