17、cking of the outside diameter of wrapped bushes (ISO 3547-2:2006, methods A, B and D) and 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 oversize b

18、etween the outside diameter of the bush and the housing bore. For this reason, checking of the outside diameter of wrapped bushes can only be carried out under a constraining load by use of specialized measuring equipment. NOTE 1 The dimensions and tolerances of wrapped bushes are given in ISO 3547-

Check the outside diameter of a wrapped bush using measuring equipment as shown in Figure 2, with a checking block

27、consisting of upper and lower halves (see Figures 3 and 4) and setting plugs (see Figures 5 and 6), at a determined checking load, Fch. Measure the outside diameter indirectly as the difference in the value of z, z. The checking load is calculated so that the bush outside diameter is reduced only el

Check the outside diameter of a wrapped bush in “GO” and “NO GO” ring gauges. 6.3 Checking method D Measurement of outside diameter, Do 120 mm NOTE See ISO

29、3547-2. Check the outside diameter of a wrapped bush above 120 mm diameter using a precision measuring tape. 7 Selection of checking method for outside diameter Method A is a precise method involving complex tooling. Method B is an attributive method using simpler tooling. Method D is used only for

30、wrapped bushes with an outside diameter 120 mm. All three methods are in general use. Method A is generally unsuitable for small bushes up to 10 mm outside diameter but is preferred for bushes over 10 mm outside diameter. 8 ISO 3547-2, test A Outside diameter, Do8.1 Measuring equipment See Tables 2

31、and 3. Typical equipment for measuring the bush consists essentially of the following components: base plate used as fixture and guiding device for the split checking block; means to generate the checking load; means to calibrate the load; 7DIN ISO 3547-5:2015-12 upper plate; system for transmitting

48、 to the nominal outside diameter, Do, of the bush. An indicating device is attached to the “free” end of the measuring tape and set to the calibration size. After the bush has been checked, the circumference indicator reading, zD, is the difference between the calibrated value of the setting plug an

From this, the outside diameter of the bush, Do, can be calculated as given in Equation (2): och,D2zDd=+(2) 10.4 Measuring errors The most frequent measuring errors are as follows. a) The tension is not sufficient to close the split line. b) The measuring tape is not wrapped around the centre line of the bush. c) Grease, dirt, burrs, etc. are present on the outside diameter (ba
