FIELD: testing equipment.
SUBSTANCE: apparatus has casing, loading drive mounted on casing, and commander device. Apparatus is further equipped with toothed gear including toothed wheel having section positioned at its crown and made in the form longitudinal slot, at 1/n length of circle of toothed crown. Toothed wheel is adapted for engagement with n number of gears rigidly connected with active grips. Active grips are positioned on bearing units of disk which is located for free rotation in conjunction with toothed wheel, parts to be tested and disk with passive grips immovably fixed thereon through predetermined angle by means of main motor-reducer with the help of electromagnetic coupling. The latter is controlled by means of measuring-commanding device which upon aligning of longitudinal slot provided on toothed wheel with precision reversing motor-reducer switches-on drive for meshing with cam, by means of which cam area of hysteresis loop is measured.
EFFECT: wider operational capabilities and improved quality of controlling of parts.
