Description
Изобретение относитс к подшипниковой промыишенности и может быть преимущественно использовано дл исследовани рассе ни упругой энергии во вращающемс подшипнике.This invention relates to a bearing industry and can be advantageously used to study the dissipation of elastic energy in a rotating bearing.
Известен способ исследовани рассе ни упругой энергии, заключающийс в том, что привод т подшипник во вращение, возбуждают в нем резонансные колебани при посто нном значении амплитуды возмущающей силы, получают амплитудно-частотную характеристику подшипника, и определ ют по ней логарифмический декремент этих колебаний, по которому оценивают рассе ние упругой энергии в подшипнике 1.A known method for studying the dissipation of elastic energy is that the bearing is driven into rotation, excites resonant oscillations in it at a constant value of the amplitude of the disturbing force, the amplitude-frequency characteristic of the bearing is obtained, and the logarithmic decrement of these oscillations is determined from it, which estimate the dissipation of elastic energy in the bearing 1.
Однако известный способ не позвол ет определить вли ние смазки на рассе ние упругой энергии в подшипнике качени .However, the known method does not allow to determine the effect of lubricant on the dissipation of elastic energy in a rolling bearing.
Цель изобретени - определение вли ни смазки на рассе ние упругой энергии в подшипниках качени .The purpose of the invention is to determine the effect of lubricant on the dissipation of elastic energy in rolling bearings.
Поставленна цель достигаетс тем, что привод т подишпник во вращение , возбуждают в нем резонансные колебани при .посто нном значении амплитуды возмущающей силы, получают амплитудно-частотную характеристикуThe goal is achieved by the fact that the subshift is brought into rotation, excites resonant oscillations in it at a constant value of the amplitude of the disturbing force, and an amplitude-frequency characteristic is obtained.
контакта тел качени и дорожек каче-i ни колец в подшипнике и по ней определ ют логарифмический декремент колебаний, по которому оценивают рассе ние упругой энергии, после определени логарифмического декремента колебаний подшипник смазывают и осуществл ют повторно возбузкдение резонансных колебаний контакта тел каче10 ни и дорожек качени с амплитудой, превышающей на 10 дб уровень максимальной спектральной составл ющей амплитудно-частотной характеристики в диапазоне частот контактного резо5 нанса при первом возбуждении, после чего определ ют логарифмический декремент колебаний по полученной амплитудно-частотной характеристике после смазки подшипника, а при оцен20 ке рассе ни упругой энергии в подшипнике учитывают значени обоих логарифмических декрементов колебаний.contact of rolling bodies and tracks of i-quality of rings in a bearing and by it determine the logarithmic decrement of vibrations, which estimate the dissipation of elastic energy, after determining the logarithmic decrement of oscillations, the bearing is lubricated and the resonant oscillations of contact of the bodies of 10 and rolling tracks are re-excited with an amplitude exceeding by 10 db the level of the maximum spectral component of the amplitude-frequency characteristic in the range of frequencies of the contact effect at the first excitation, after which is determined by the logarithmic decrement of oscillations based on the obtained amplitude-frequency characteristic after lubrication of the bearing, and when estimating the dissipation of elastic energy in the bearing, the values of both logarithmic oscillatory decrements are taken into account.
