Изобретение относитс к области общего машивастроени , а именно к способам определени нат га колец шарикопадшипников прИ их посадке на вал и в корпус.The invention relates to the field of general engineering, in particular, to methods for determining the tension of the ball-bearing rings when they are mounted on the shaft and into the housing.
ИзВбстиы способы определени нат га колец шарикоподшипни,ков, включающий определение осевой жесткости по частоте резонаисных колебаний.There are ways to determine the tension of ball bearing rings, forks, including the determination of axial stiffness based on the frequency of resonant vibrations.
Такие способы, широко используемые в насто щее врем дл измерени жесткостных характеристик упругих элементов, непригодны, однако, дл высокочастотных измерений.Such methods, which are now widely used to measure the stiffness characteristics of elastic elements, are unsuitable, however, for high-frequency measurements.
По предлагаемому способу дл -повыщени точности измерени величины нат га колец осевую жесткость щарико падшипника измер ют до посадки, после посадки внутреннего кольца и после посадки наружного кольца и по разност м измерегшых величи1Н жесткости определ ют величину нат га.According to the proposed method for precision measurement of the tension of the rings, the axial stiffness of the ball bearing is measured before fitting, after seating the inner ring and after fitting the outer ring and determining the tension value by the difference of the measured stiffness values.
Подшипник устанавливают на подвижную часть вибростанда и нагружают грузом. Постепенно измен частоту питающего вибростенд напр жени , по увел1ичвнию амплитуды колебаний подвижной части стенда наход т резонаНсную частоту, точное значение которой ф.чксируют цифровым частотомером. По И3(вест1ной резонансной частоте и параметрам колебательной системы вычисл ют по известНЫМ формулам осевую л есткость подшипника .The bearing is mounted on the movable part of the vibrostand and is loaded with a load. Gradually changing the frequency of the voltage supplying the vibrostand, to increase the amplitude of the oscillations of the movable part of the stand, a resonant frequency is found, the exact value of which is measured using a digital frequency meter. According to I3 (the resonant frequency and the parameters of the oscillatory system are calculated by the known formulas axial bearing resistance.
Затем уста1 авливают внутреннее кольцо с нат гом на вал и вновь с 1помощь о вышеуказанных операций измер ют жесткость. По полученной разности жесткостей вычисл ют величину нат га. Аналогично определ ют величину нат га при посадке наружного кольца в корпус.Then, the inner ring is inserted with tension on the shaft, and again with the help of the above operations, the stiffness is measured. From the obtained stiffness difference, the tension value is calculated. The tension value when fitting the outer ring into the housing is determined similarly.
Предмет изобретени Subject invention
Способ определени нат га колец шарикопадщилников при Их .посад1ке ,на вал и в корпус , включающий определение осевой жесткости подшипника по частоте резонансных колебаний , отличающийс тем, что. с целью (повышени точности, измер ют осевую жесткость шарикоподшипн1к а до посадки, после посадки внутреннего кольца и после посадки наружного кольца и по разност м измеренных 1величин жест костей определ ют величину нат га.The method of determining the tension of the rings of the ball pads at Their landing on the shaft and into the housing, including the determination of the axial rigidity of the bearing from the frequency of resonant oscillations, characterized in that. In order to increase accuracy, the axial rigidity of the ball bearings is measured before seating, after seating the inner ring and after seating the outer ring, and the difference of the measured 1 magnitude of stiffnesses determines the tension value.
