DEVICE FOR FRICTION TEST OF MATERIALS Russian patent published in 2010 - IPC G01N3/56 

FIELD: mechanics.

SUBSTANCE: device includes driving element, base on which there arranged is a holder with a coutersample fixed on it, which is attached to driving element, loading element and holder of the tested sample. Holder of the tested sample is made in the form of two discs detachably attached to each other with a gap between their end surfaces. On inner side of one disc located from the side of loading element there made is cylindrical projection with conical tip, and on disc surface there made are through threaded holes. On inner side of the other disc located from the side of coutersample holder there made is blind stepped hole for arrangement of cylindrical projection and conical tip of the first disc. On the surface of the second disc there made are holes for arrangement therein of threaded fasteners attaching discs to each other. On external surface of the second disc there made is a slot for arrangement and attachment of the tested sample. Fixtures are arranged in holes of the second disc with a gap, and height of cylindrical projection of the first disc ensures free rolling of the first disc relative to the second one.

EFFECT: improving installation accuracy of sample and keeping its position during the test, increasing efficiency of tests and operation of the device.
