FIELD: testing equipment. SUBSTANCE: gear testing samples for crack resistance has tie rod, rod and means to form initial load in the form of two levers, some of which are intended for interaction with sample and the other arms - with butt of rod. Rod carries heating element. Rod extends with heating of element and transmits load on sample by means of levers. Controlling voltage across heater one can change load on sample remotely which makes it possible to examine crack resistance of elements in points difficult for access. EFFECT: expanded operational capabilities. 2 cl, 1 dwg
