8、. 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, governmental and non

9、-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 Directives, Part

10、 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 bodies casting

11、a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

19、d F maxmaximum value of load applied to the beam flange during testing according to its quality class 4 Quality classification Beam flanges are classified according to four quality classes. The designation of the quality classes is Q1, Q2, Q3 or Q4. Depending on the quality class, the beam flanges a

20、re loaded with different ultimate loads. These limit values are given in Clause 6. For examples of application by quality class, see Annex A. ISO 8116-4:2008(E) 2 ISO 2008 All rights reserved5 Test methods 5.1 Principle The beam flange is subjected to a test load and the resulting deformation is mea

21、sured. For weavers beams, the test load is applied to the flange via a beam barrel. For warpers beams and sectional beams, the load is applied to the beam flange via a pressure plate. A pressure ring with a defined inner diameter is used as an anvil. The permanent deformation and the plastic deforma

22、tion of the flange shall not exceed the defined limit values when the maximum load is applied. 5.2 Apparatus 5.2.1 Press device, with indications for the application of the test load. 5.2.2 Three dial gauges, for determination of deformation of the flange with an accuracy of 0,01 mm. 5.2.3 Measureme

23、nt device, for joint installation of the three dial gauges on the bearing device, in an angle of 120 each. 5.2.4 Steel pressure ring. 5.2.5 Beam barrel, for load application (for weavers beams). 5.2.6 Pressure plate, for load application (for warpers beams and sectional beams). 5.3 Testing configura

24、tion For measurement of flange deformation, three dial gauges are installed on the bearing device by means of the measurement device. These are used to measure the relative path between the outer diameter of the beam barrel d 2and the circle diameter d 1 20 mm. The dial gauges are staggered by 120.

25、The testing configuration for weavers beams is given in Figure 1. The testing configurations for warpers beams are given in Figure 2 and Figure 3.

The beam flange, the pressur

33、e ring and the pressure plate, if required, are aligned centrally below the press loading pad. Stepwise loading of the flange shall occur in steps to be chosen usefully. The load applied and the deformation are determined at the test area for each loading step. The value of the total deformation is

34、calculated from the average of the three measurement values. After each load step, unloading of the flange is optional. After unloading, the values indicated are read with the dial gauge. The values for the plastic deformation are calculated from the average of the three measurement values. Then loa

35、ding is applied with the next higher load value. This procedure is repeated until the defined maximum test load of the corresponding quality class as given in Equation (2) and Table 1 is reached. The beam flange corresponds to the quality class if the value measured for the total deformation and the

36、 value measured for the plastic deformation are below the values obtained when using Equation (3) and Equation (4). ISO 8116-4:2008(E) 6 ISO 2008 All rights reservedOnce the given maximum load has been achieved, the plastic deformation shall be measured after unloading. Subsequently, the dial gauges

37、 are set to “zero”. The maximum test load shall again be applied. After unloading, only an insignificantly low residual deformation value shall be read. 6 Pressure ring diameter, maximum test load and limit values of deformation The diameter of the pressure ring, maximum test load and limit values o

38、f deformation shall be calculated using Equations (1), (2) or (3) for any flange geometry: for weavers beams in accordance with ISO 8116-3, the values are given in Table 2; for warpers beams in accordance with ISO 8116-2, the values are given in Table 3; for sectional beams in accordance with ISO 81

39、16-5, the values are given in Table 4. 6.1 Pressure ring diameter The diameter of the pressure ring is calculated, depending on the inner and outer diameter of the beam flange, using Equation (1): 33 12 i 22 12 2 3 dd D dd = (1) where D iis the inner diameter of the pressure ring, in millimetres; d

40、1is the outer diameter of the beam flange, in millimetres; d 2is the outer diameter of the beam barrel, in millimetres. The tolerance for the diameter of the pressure ring, D i , may not exceed 1 mm. NOTE Equation (1) corresponds to the centre of the diameter of a circular ring segment on the condit

41、ion that the angle of the circular ring segment reaches zero. In practice, the actual load on the beam flange is different, depending on the winding. 6.2 Maximum test load Depending on the quality class, the maximum test load is calculated from the maximum test load given in Table 1 multiplied by th

42、e maximum winding area of the beam flange, using Equation (2). max max i F Ap = (2) where F maxis the maximum test load, in kilonewtons; A maxis the maximum winding area of the beam flange, in square millimetres; 22 max 1 2 () 4 A dd = p iis the maximum test load, in megapascals.

The limit value of the plastic deformation at maximum test load amou

45、nts to a quarter of the limit value of total deformation in the case of initial loading of the beam flange. If the maximum test load is again applied to the beam flange, as shown in Equation (4), the proportion of plastic deformation shall be insignificantly low. tot lim 12 plast lim () 4 1000 f dd
