Изобретение относитс к подшипниковой промь1шленности и может быть преимущественно использовано дл определени жестких характеристик шарикоподшипниковых опор ротора.The invention relates to a bearing area and can be advantageously used to determine the rigid characteristics of ball bearing rotor bearings.
Известен способ определени жесткостных характеристик шарикоподшипниковых опор ротора, заключающийс в том, что возбуждают вынужденные осевые колебани ротора и измер ют его резонансную частоту при вертикальном положении оси вращени .A known method for determining the stiffness characteristics of ball-bearing rotor bearings, which consists in stimulating forced axial oscillations of the rotor and measuring its resonant frequency with the vertical position of the axis of rotation.
Однако способ не позвол ет определ ть осевую неравножестк сть опор ротора.However, the method does not allow to determine the axial inequality of the rotor supports.
Цель изобретени - определение осевой неравножесткости шарикоподшипниковых опор ротора.The purpose of the invention is to determine the axial unequality of the ball bearings of the rotor.
Поставленна цель достигаетс за смет того, что создают вынужденные осевые колебани ротора с заданной 1 |мплитудой колебаний на частоте, н«р вной ч.ютоте резонана, измер ютThis goal is achieved by estimating what creates forced axial oscillations of the rotor with a given 1 | mplitudoy oscillations at a frequency that is not equal to the frequency of a resonant, measured
амплитуду колебаний ротора на частоте , равной удвоенной частоте вынужденных колебаний, а при измерении резонансной частоты разворачивают ось вращени ротора в вертикальной плоскости на 180°, измер ют амплитуду колебаний ротора на частоте, равной частоте вынужденных колебаний и рас читывают осевую неравножесткость ша«.рикоподтипниновых опор ротора по фор10 мулеthe amplitude of oscillation of the rotor at a frequency equal to twice the frequency of forced oscillations, and when measuring the resonant frequency, rotate the axis of rotation of the rotor in a vertical plane 180 °, measure the amplitude of oscillations of the rotor at a frequency equal to the frequency of forced oscillations and calculate the axial disparity rotor for 10 mule
