Abstract

L'invention concerne les constructions mécaniques. La machine faisant l'objet de l'invention est caractérisée notamment en ce que le dispositif 13 destiné à appliquer la charge aux éprouvettes à essayer 11, 14 et à transmettre le moment de frottement des éprouvettes au dispositif 15 de mesure dudit moment possède un arbre creux 25 monté coaxialement à la broche 1 et à l'intérieur duquel est disposée coaxialement une tige 34 pouvant se déplacer axialement et coopérant avec le vérin pneumatique 16 pour transmettre la charge aux éprouvettes. L'invention permet notamment de déterminer sans distorsions le moment de frottement et par conséquent le coefficient de frottement des matériaux, ainsi que de réduire la durée de rodage des éprouvettes.The invention relates to mechanical constructions. The machine forming the subject of the invention is characterized in particular in that the device 13 intended to apply the load to the test pieces to be tested 11, 14 and to transmit the frictional moment of the test pieces to the device 15 for measuring said moment has a shaft hollow 25 mounted coaxially with the spindle 1 and inside which is arranged coaxially a rod 34 able to move axially and cooperating with the pneumatic cylinder 16 to transmit the load to the specimens. The invention makes it possible in particular to determine the frictional moment without distortion and consequently the coefficient of friction of the materials, as well as to reduce the running-in time of the specimens.
