Description

При включении питаии электромагиитов на ротор, вращающийс в магнитном поле, в св зи с его взаимодействием с электромагнитами , будут действовать переменные моменты , ускор ющие или тормоз щие его вращение . Число таких действий в пределах одного оборота зависит от числа включенных электромагнитов . Действие на вал переменного пульсирующего момента создает угловые колебани - вибрации вала, которые передаютс иа внутреннее кольцо испытываемого подшипника . Частота вибрации кратна частоте вращени и зависит от числа включенных электромагнитов. Амплитуда вибрации регулируетс напр жением тока питани электромагиитов и может быть увеличена уменьщеиием жесткости вала на участке между ротором 7 и опорным подшипником 4.When electromagnit power is switched on, a rotor rotating in a magnetic field, in connection with its interaction with electromagnets, will have variable moments that accelerate or inhibit its rotation. The number of such actions within one revolution depends on the number of activated electromagnets. The action on the shaft of a variable pulsating moment creates angular oscillations — shaft vibrations, which are transmitted to the inner ring of the bearing under test. The vibration frequency is a multiple of the rotation frequency and depends on the number of electromagnets involved. The vibration amplitude is regulated by the voltage of the current supplying electromagites and can be increased by decreasing the rigidity of the shaft in the area between the rotor 7 and the support bearing 4.
