INSTALLATION FOR FATIGUE TESTS OF SAMPLES OF MATERIALS AT BEND

摘要

FIELD: machine building. ^ SUBSTANCE: installation consists of power frame, of device for sample loading arranged on this frame, of support elements for placement of samples on them and of mechanism for transfer of support elements. The support elements correspond to balls. The mechanism of support elements transfer is made as a platform, a drive of platform rotation and a plate positioned parallel to surface of the platform and connected to the frame. A spiral groove is made on surface of the platform; slits are cut in the plate radially to rotation axis of the platform. The balls are inserted in the groove and are positioned in the slits. ^ EFFECT: test operations at radial changes of sample support area under specified modes during bend tests. ^ 1 dwg
