Способ определения критических скоростей ротора, работающего в зарезонансной области, заключающийся в том, что в свободный торец вала ротора ввинчивается валик, на котором с помощью подшипника качения устанавливается с возможностью свободного вращения маятник с изменяемым моментом инерции его массы и при вращении вала ротора с рабочей частотой вращения маятник в зависимости от соотношения между моментом инерции его массы и моментом трения в опоре начинает вращаться с угловой скоростью, равной одной из критических скоростей ротора.A method for determining the critical speeds of a rotor operating in a non-resonant region, namely, a roller is screwed into a free end of the rotor shaft, on which a pendulum with a variable rotation moment of its mass inertia is mounted with a rolling bearing and when the rotor shaft rotates at an operating frequency The rotation of the pendulum, depending on the ratio between the moment of inertia of its mass and the moment of friction in the support, begins to rotate with an angular velocity equal to one of the critical rotor speeds.
