摘要
FIELD: testing equipment.;SUBSTANCE: tested samples are assembled with a high-strength profiled holder, to which increasing axial load is applied with rest of samples against the support. At the same time previously gripping jaws, which are a support, where tested half-couplings are installed with internal thread or a comb assembled with the profiled holder, are exposed to independent axial force, moving them downwards to provision of radial force that presses the half-couplings, being equivalent to operation load. The axial force applied to the profiled holder is increased to cutting of all or several teeth of the thread or comb on half-couplings. The cut force is fixed and compared with the value, which has been in advance experimentally justified and meets the requirements of quality to the manufactured half-couplings.;EFFECT: improved quality of control.;2 cl, 1 dwg
