LOADER FOR MACHINE FOR FRICTION AND WEAR TESTING Russian patent published in 1999 - IPC

FIELD: testing equipment. SUBSTANCE: loader has foundation, holders of mobile sample and countersample, loading mechanism, platform and rolling-contact bearings. Loading mechanism interacting with holder of mobile sample is put on foundation. Holder of countersample is placed on platform with the aid of rolling-contact bearings. Rotation axis of rolling-contact bearings is located on line of crossing of friction surface of countersample with symmetry axis perpendicular to its plane that is oriented in direction of sliding of mobile sample to ensure technical result consisting in increased accuracy of setting of sample with reference to countersample. EFFECT: increased accuracy of setting of sample with reference to countersample. 2 dwg
