FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanical engineering and namely to methods and means of tribotechnical tests, in particular to methods and devices for testing units with dry friction pairs. The reciprocating movement of one of the tested elements of the friction pair in the installation is set by a form-locked cam mechanism of the upper pair containing a cam with a groove of a special profile and a roller interacting with the lateral surfaces of the cam groove and connected with the FP moving element providing its reciprocating movement with constant speed. The contact pressure in the FP is set by weights through the lever system.
EFFECT: creating an installation for selecting and testing materials for optimal friction pairs operating under conditions as close as possible to real conditions.
