It also specifies test designations. Since the wall thi

15、ckness of the bush is measured in the free condition, no special test data is required for this on the drawing (see ISO 3547-5 and ISO 3547-6). NOTE Depending on the manufacturing method, the back of the bushes can show isolated light depressions and, similarly, bushes with lubrication holes, groove

16、s and bore indentations can show distortion. The wall thickness must therefore be measured away from these areas. 2 Normative references The following referenced documents are indispensable for the application of this document.

26、 Check the outside diameter, Do, using precision measuring tape, in accordance with Clause 10. 7 Test A 7.1 Description This test is applicable to 2Doup to 180 mm. The test rig consists of a base on which the two parts of the checking block are mounted (see ISO 3547-5). A setting plug is inserted in

27、 the checking block and the two halves of the checking block are pressed towards one another using the given checking load, Fch, and the indicator reading set. The setting plug is then removed and replaced by the bush to be checked, and the checking load reapplied. After the bush has been inserted,

28、the distance, z, between the two halves of the checking block changes under checking load Fchand the distance indicator reading, z, is recorded. From this, Docan be calculated. Flanged bushes may be checked either before or after flange forming at the option of the manufacturer. 7.2 Calculation basi

29、s 7.2.1 Elastic reduction, v, of outside diameter, DoThe elastic reduction, v, of the outside diameter, Do, is the difference between Dounder zero load and the resultant diameter when the checking load, Fch, is applied. Force Fchshall be sufficient to ensure that the bush conforms properly to the su

30、rface of the test housing and that the results in the elastic reduction, v, of the outside diameter are in accordance with Table 2. 8 DIN ISO 3547-2:2015-12 Table 2 Elastic reduction, v, of the outside diameter, Do, under checking load, FchDimensions in millimetres Donominal v u 6 0,003 6 u 12 0,006

42、ion of data on drawing 8 Test B 8.1 Description The test is applicable to 2Doup to 120 mm. The test is carried out with two ring gauges, a GO ring gauge and a NO GO ring gauge. The gauge diameters are determined empirically, based on the maximum and minimum values of the outside diameter (see ISO 35

43、47-1:2006, Table 7) to be checked, and shall be agreed between supplier and user. It shall be possible to press the bush into the GO ring gauge with hand pressure (maximum force 250 N). However, with the same force it shall not be possible for the bush to enter the NO GO ring gauge (see ISO 3547-5).

44、 12 DIN ISO 3547-2:2015-12 NOTE In some cases, the accuracy of the check could be affected, e.g. by the out of roundness of the bush or by butt joints which are not closed. For this reason Test A is preferred. 8.2 Obtaining data Example Given: Bush ISO 3547 30A 34 30 S3 Outside diameter: ( )0,085o0,

46、 example: Test B to ISO 3547-2 GO gauge diameter = 34,095 mm NO GO gauge diameter = 34,045 mm 9 Test C 9.1 Description In order to check the inside diameter, Di,the bush is pressed into a ring gauge, whose nominal diameter corresponds to the dimension specified in Table 6. Other details of the ring

47、gauge should be according to ISO 3547-6. The test is applicable to 2Diup to 120 mm. Inside diameter Di,chshall be measured with a three-point measuring instrument in accordance with ISO 12301, or checked with a GO and NO GO plug gauge. The plug gauges are calculated from the ring gauge diameter, dch

48、, 1, as follows. GO plug: dch, 1 2 s3,max. NO GO plug: dch, 1 2 s3, min. The GO plug gauge shall enter the bush with minimum effort; the NO GO plug gauge shall not enter the bush manually (maximum force 250 N). When the bush is pressed into the ring gauge, it is possible that there will be a permane

49、nt reduction in the outside diameter. In order to enable the supplier and user to compare results, the test method should be agreed between them. 13DIN ISO 3547-2:2015-12 Table 6 Ring gauge inside diameter, dch,1, for checking bush inside diameter, Di,ch Dimensions in millimetres Donominal dch, 1a u 10 Do+ 0,008 10 u 18 Do+ 0,009 18 u 30 Do+ 0,011 30 u 50 Do+ 0,013 50 u
