Researches on hydraulic devices for direct drive of pulleys in wire ropes testing machines

Round Table On The Present Trends Of Wire Rope Endurance – Milano 1973

 Feasibility tests.

At the Institute of Machine Construction of the Polytechnical School of Turin, a research has been undertaken to study the possibility of replacing conventional (mostly mechanical) driving units, by a direct hydraulic driving device, in order to be able, in the easiest way, to change the stroke angle and to get, as far as possible, a sinusoidal stroke avoiding irregularities and impacts of mechanical drive units and allowing a perfect balancing of inertia forces by means of linear springe L-1_7 L-2_7.
