UNIT FOR ALTERNATING SEPARATE LOADING SAMPLE FOR TORSION, CANTILEVER BEND, COMPRESSION AND CANTILEVER BENDING IN ONE SIMULTANEOUS TURN OF THREE TOOTHED WHEELS

摘要

FIELD: test equipment.;SUBSTANCE: invention can be used in factory and research laboratories. Installation includes a base, passive and active sample grips, a pulley with two tie rods and with weights each and gear motor. Installation additionally includes a rectangular frame connected with base, three shafts mounted thereon, one of which rotates gear wheel, and on other two are turned one gear wheel. Gear wheels are connected to each other, lower and mid gears via crank gears move bogies over beams, there are slots in bogies with rods and connected to base, cylinders, connected with pins, tubular rod with two slots connected to base, arranged in a tubular rod piston, connected to piston-rod, and spring located between sample and piston.;EFFECT: broader functional capabilities by testing a sample not only for compression and torsion at constant and variable loads, and on alternating separate loading sample for torsion, cantilever bend, compression and cantilever bending in one simultaneous turn of three gears.;1 cl, 7 dwg
