FIELD: test equipment.
SUBSTANCE: invention relates to test equipment, in particular to test equipment, namely to test benches for testing samples of elastomer bearings. Device comprises a frame with a hydraulic cylinder, an electric motor, a crank mechanism equipped with a connecting rod, and measuring devices. Three-arm lever is hinged on the frame, to which a connecting rod is attached through a hinge, which is connected to the crank. To lever bearings by means of crosspieces are attached shanks of flat links, which are connected by opposite shanks to bearings by means of crosspieces of rocker arm. One end of the lever is hinged to the frame web, and the other end is connected to a force sensor. Bracket is fixed on the lever. Hydraulic cylinder is connected to force sensor via hinged tie-rod.
EFFECT: increased accuracy of reproduction and measurement of loads, elimination of overloads of samples during tests, reduced labor intensity of tests.
