12、aracteristics DIN ISO 3547-6:2015-12 41 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 describes the necessary checking methods and measuring equipment. Wrapped bushes in the free condition are flex
13、ible, 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 in this part of ISO 3547 are given in millimetres except where otherwise noted/designated. NOTE 2 The dimensions
14、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 the subject of ISO 3547-5. 2 Normative references The following referenced documents are indispensable for the ap
15、plication 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、utside 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 nominal diameter corresponds to the dime
19、nsion 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, is measured with a three-point measurin
20、g 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 between supplier and user, the dimensions

27、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 when introduced into the
28、 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. Subsequently, the ins
29、ide 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. Where it is necessary to
30、 limit the maximum force, it shall be agreed between supplier and user.
