6、y . 7 BS ISO 3547-6:2007iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested

7、 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 part in the work. ISO collaborates closely with the Inter-national Electrotechnical Com

8、mission (IEC) on all matters of electrotechnical standardization. International Standards are drafted according to the rules 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 co

9、mmittees 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 that some of the elements of this document may be the subject of patent rights. ISO shall no

10、t be held responsible for identifying any or all such patent rights. ISO 3547-6 was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 5, Quality analysis and assurance. This part of ISO 3547 cancels and replaces ISO 12307-2:2000, which has been technically revised. ISO 3547

11、 consists of the following parts, under the general title Plain bearings Wrapped bushes: Part 1: Dimensions Part 2: Test data for outside and inside diameters Part 3: Lubrication holes, grooves and indentations Part 4: Materials Part 5: Checking the outside diameter Part 6: Checking the inside diame

12、ter Part 7: Measurement of wall thickness of thin-walled bushes BS ISO 3547-6:20071Plain bearings Wrapped bushes Part 6: Checking the inside diameter 1 Scope The part of ISO 3547 specifies, following ISO 12301, the checking of the inside diameter of wrapped bushes (see ISO 3547-2:2006, method C) and

13、 describes the necessary checking methods and measuring equipment. Wrapped bushes in the free condition are flexible, but after insertion they adapt largely to the shape of the housing bore due to the interference between the outside diameter of the bush and the housing bore. NOTE 1 All dimensions i

14、n this part of ISO 3547 are given in millimetres except where otherwise noted/designated. NOTE 2 The dimensions and tolerances of wrapped bushes are given in ISO 3547-1. NOTE 3 Checking of the wall thickness is the subject of ISO 3547-7. NOTE 4 Checking of the outside diameter of wrapped bushes is t

15、he subject of ISO 3547-5. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

18、ter of the ring gauge millimetres dch, 2Outside diameter of the plug gauge millimetres 4 Method of checking The free diameter of a wrapped bush is not measured directly because of the flexible nature of the components. To check the inside diameter, Di, ch, the bush is pressed into a ring gauge whose

19、 nominal diameter corresponds to the dimension of the housing. For bushes specified in ISO 3547-1, the tolerance class of housing bore is normally H7. When the bush is pressed into the ring gauge, it is possible that there is a permanent reduction in the outside diameter. The inside diameter, Di, ch

20、, is measured with a three-point measuring instrument or with a GO or a NO GO gauge. In order to enable the supplier and the user to compare results of this test it shall be agreed whether results shall be obtained by measuring or by gauging. 5 Test equipment 5.1 Ring gauge Unless otherwise agreed b

27、ned (60 HRC to 64 HRC) and non-ageing steel. 5.5 Measuring errors Frequent measuring errors are as follows. a) Ring gauge and plug gauge are damaged or worn. b) Ring gauge and plug gauge have no lead-in chamfer. c) Bush is misaligned when introduced into the ring gauge. d) Plug gauge is misaligned w

28、hen introduced into the bush. e) Width of the ring gauge is less than the width of the bush. f) Grease, dirt, damages, burrs and swelling are present around features on the bush and test equipment. 6 Procedure The bush shall be introduced into the ring gauge from that side having the lead-in chamfer

29、. Subsequently, the inside diameter shall be determined by means of a) the three-point measuring instrument; b) the GO plug gauge (see Figures 2 and 3), which shall be inserted with minimum effort; the NO-GO plug gauge, which shall not be able to be inserted manually with a maximum force of 250 N. W

30、here it is necessary to limit the maximum force, it shall be agreed between supplier and user.
