DEVICE TO TEST MATERIALS FOR FRICTION AND WEAR Russian patent published in 2010 - IPC G01N3/00 

FIELD: instrument making.

SUBSTANCE: invention relates to equipment for tribometry of structural and lubricating materials. Proposed device comprises rotation drive with its stator is coupled, via bearing, with rotor. The latter incorporates two tested disks arranged with a gap between them, each interacting with tested indenters fitted on strain-measuring beams attached onto stator to elastically press said indenters to flat surface of appropriate disk and said disk to rotor. It incorporates also strain gages arranged on said beams and connected with recorders. Every beam represents a monoblock consisting of two pairs of plane-parallel springs with their ends interconnected by strips and turned through 90°, relative to each other and along their axis parallel to the plane of springs, to make a single whole in one of strips. Note here that beams are arranged on stator so that the plane of one pair of springs is parallel to tested disk surface.

EFFECT: higher accuracy.
