MACHINE OF HIGH-SPEED REVERSIBLE FRICTION WITH CONTROLLED DYNAMIC LOADING Russian patent published in 1999 - IPC

FIELD: testing of materials for friction and wear. SUBSTANCE: machine has foundation, movement drives mounted on it and coupled to drives of movement of platform, holder of countersamples, holders of sample and loading mechanism. The latter is manufactured in the form of cylinder of two-way action. Machine is equipped with guides for movement of sample along loading axis, hydraulic drive and damper installed between holder of sample and rod of cylinder of loading mechanism. EFFECT: simplified design and high operational reliability of machine making it possible to model conditions close to work of practically any unit of reversible friction. 5 dwg
