DEVICE FOR MEASURING ANGULAR DEFORMATIONS OF THE MATERIAL OF THE CYLINDRICAL SAMPLE WHEN ITS TURN

摘要

A device for measuring the angular deformations of a material of a cylindrical sample during its torsion, comprising a housing, a strap connected to the housing, with supporting and writing cores fixed on it, and a removable recording medium mounted on a supporting prism, with the supporting core being located in a previously made recess of the sample surface , and the writing core touches the working surface of the removable recording medium, while the writing core has a higher hardness than the removable recording medium, characterized in that The whisker is made in the form of a prism with the possibility of its support on the cylindrical surface of the test sample, while the bar is cantilevered on the case and directed parallel to the axis of the sample and has a support core near the case, and at its free end there is a writing core supplied by the spring in the direction of the test sample, which ensures its intense contact with the working surface of the removable recording medium, while the removable recording medium has the form of a plate mounted on a support prism mounted on the studied the first sample without the possibility of its displacement relative to the sample during its deformation, moreover, the case, plank, support and writing cores, spring, support prism, removable recording medium are made of materials resistant to low and (or) high temperatures and (or) aggressive wednesday
