The mechanical
21、strength of sectional beams for knitting machines shall be verified, depending on the quality class, by the test method given in ISO 8116-4. 5 Circular axial run-out tolerance, Ta, of flanges The permissible circular axial run-out tolerance, Ta, of flanges given in with Table 2 shall be met. The run
22、-out tolerance shall be measured in accordance with ISO 8116-8.

23、metres and calculated using Equation (1): 1r0,251000lT= (1) The run-out tolerance shall be measured in accordance with ISO 8116-8. 7 Residual imbalance Depending on the circumstances, it may be necessary to fix a value for the residual imbalance of sectional beams. In general, a quality grade G 6,3
24、in accordance with ISO 1940-1 will be appropriate. If special conditions call for another grade, this shall be specified. 8 Taper reception At a flange diameter, d1, of 762 mm or greater, the sectional beam may be designed with a taper reception as given in Figure 2 in order to achieve a better cent

26、; d) surface quality and, if possible, the treatment (paint, chromium-plating, nickel-plating, etc.) of the beam in contact with the material to be wound (inner sides of the flanges and the surface of the outside barrel diameter); e) number of grooves (one or two) to be included in the boss of each
27、flange; f) taper reception (if received). 10 Designation The designation of a sectional beam in accordance with this part of ISO 8116 shall include the following information in the order given: a) “Sectional beam”; b) reference to this part of ISO 8116, i.e. ISO 8116-5; c) flange diameter, d1, in mi
28、llimetres; d) overall length, l2, in millimetres; e) quality class Q1, Q2, Q3 or Q4 in accordance with ISO 8116-4.
