7、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. International organizations, govern
8、mental 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 rules given in the ISO/IEC Di
9、rectives, 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 least 75 % of the member b
10、odies 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 3547-3 was prepared by Technical Committee ISO/TC 123, Plain bearings, Subc
11、ommittee SC 3, Dimensions, tolerances and construction details. This second edition cancels and replaces the first edition (ISO 3547-3:1999), which has been technically revised. ISO 3547 consists of the following parts, under the general title Plain bearings Wrapped bushes: Part 1: Dimensions Part 2
12、: Test data for outside and inside diameters Part 3: Lubrication holes, grooves and indentations Part 4: Materials The following parts are under preparation: Part 5: Checking the outside diameter Part 6: Checking the inside diameter Part 7: Measurement of wall thickness of thin-walled half-bearings

14、: Lubrication holes, grooves and indentations 1 Scope This part of ISO 3547 specifies dimensions of lubrication holes, grooves and bore indentations on wrapped bushes made of solid and multi-layer bearing material for plain bearing applications. NOTE Wrapped bushes with lubrication holes, grooves or
15、 bore indentations in accordance with this part of ISO 3547 can be ordered with dimensions in accordance with ISO 3547-1 and made from materials in accordance with ISO 3547-4. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE The grooved cross-section of Figures 4 and 5, and 7 and 8, are shown on an enlarged scale. Widening of the l
25、ubrication grooves in the area of the lubrication holes, at the split and at the end faces of the bush, is permissible. Lubrication grooves are normally represented on the developed shape of the bush. Distortions to the groove form can occur during the subsequent manufacturing operations. In order t
26、o facilitate measurement, the dimensions of the bush thickness remaining at the base of the groove may be specified on the drawing as the control dimension.
