DEVICE FOR TESTING OF MACHINE PART SURFACES FOR BACK-TO-BACK ENDURANCE Russian patent published in 2009 - IPC G01N3/56 

FIELD: machine building.

SUBSTANCE: invention is related to technology of machine building, to devices for testing of machine part surfaces for back-to-back endurance. Device comprises base, plate installed on it with indicator of axial load and holder of samples, and roller with deforming bodies intended for interaction with samples. Roller is arranged in the form of disc installed with one end in cartridge on spindle of rotation drive, and the other end is equipped with ring from antifriction material with indents for location of deforming bodies in them and separator. On the base installed on reciprocal motion drive, there are two guide planks and pad for fixation of plate with the possibility of longitudinal reciprocal displacement of the latter. Between supports of movable plate and base there is compression spring installed, which is aligned with screw and creates static force of samples pressing to roller.

EFFECT: expansion of technological resources, increased efficiency, arrangement of effect at contact wear of rolling and slipping ratio.
