11、al standards bodies (ISO member bodies). The work of preparing International Standards is 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. Internatio
12、nal organizations, governmental and non-governmental, in liaison with ISO, also take part 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 rule
13、s given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare 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 l
14、east 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8139 was prepared by Technical Committee ISO/TC 13

BS ISO 8139:2009 ISO 8139:2009(E) iv ISO 2009 All rights reservedIntroduction In pneumatic fluid power systems, power is transmitted a
16、nd controlled through a gas under pressure within a circuit. One component of such systems is the pneumatic fluid power cylinder. 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 cylindric
17、al bore.

The rod-end spherical eyes have been designed specifically for use with 1 000 kPa 10 bar 1) series cylinders manufactured in accordance with ISO 6430, ISO 6432 and ISO 15552, but this does not limit their application. The spherical bearing end ey
19、es are used on piston rods of pneumatic cylinders for mechanically transmitting the cylinder force under oscillatory rotational and tilting movements. The design of the rod-end spherical eyes is based on the maximum forces resulting from the specified internal diameter of the cylinders and pressure

However, in exceptional cases (for example cylinder installation difficulties), a tolerance of f7 can be admitted. In
27、this instance, a case-hardened shaft is recommended as movement occurs between the shaft and the bearing bore. Lubrication shall then be effected through the shaft. 5.1.2 The specified tilting angle of 4 can still be obtained when the clevis inner faces abut the side faces of the inner ring of the s
28、pherical plain bearing. 5.1.3 The rod-end spherical eyes shall be locked with a locking nut. 5.2 Bearing life 5.2.1 The life of the spherical plain bearing is influenced by many factors such as specified load, direction of load, angle of oscillation, type of lubricant and frequency of lubrication. 5
29、.2.2 The spherical plain bearings are designed to give an acceptable bearing life under normal operating conditions. 5.2.3 Where a constant unidirectional load is applied or other unusual operating conditions exist, consultation with the supplier is recommended. 5.3 Lubrication 5.3.1 Sufficient lubr
30、ication shall be provided for the satisfactory performance of the rod-end spherical eyes. 5.3.2 The method and frequency of such lubrication depend on the particular operating conditions. 6 Example of ordering designation A rod-end spherical eye with a bore of CN = 20 mm and steel-on-steel surface s
