  • Investigating Strength Of Materials By Application Of Mechanical Stress (AREA)

Description

Дл  гашени  колебаний может быть установлен газостатический подшипник 17.To suppress oscillations, a gas-static bearing 17 can be installed.

Тензодатчики 8, установленные па держателе 7 или на выносной пластине 14, позвол ют измер ть момент трени  только от сил трени , действуюших в стыке пары трени . Благодар  исключению вли ни  различных сопротивлений повышаетс  точность измерени  момента трени .Strain gauges 8, mounted on a holder 7 or on a remote plate 14, can measure the moment of friction only from the friction forces acting at the junction of the friction pair. By eliminating the effect of various resistances, the accuracy of the measurement of the frictional moment is improved.
