1one
Изобретение относитс к подшипниковой промышленности и может быть преимущественно использовано дл определени жесткости подшипников.The invention relates to the bearing industry and can be advantageously used to determine the rigidity of bearings.
Известен способ определени жесткости подшипников, заключающийс в том, что устанавливают шпиндельный узел на двух подшипниках, нагружают вал шпиндел посто нной радиальной силой и измер ют его радиальные перемещени fl.A known method for determining the stiffness of bearings consists in installing a spindle assembly on two bearings, loading the spindle shaft with a constant radial force, and measuring its radial movements fl.
Однако известный способ не позвол ет определить жесткость каждого подшипника в собранном шпиндельном узле. ., However, the known method does not allow determining the stiffness of each bearing in the assembled spindle assembly. .
Цель изобретени - определение жесткости каждого подшипника в собранном шпиндельном узле.The purpose of the invention is to determine the stiffness of each bearing in the assembled spindle assembly.
Поставленна цель достигаетс тем, что по полученным перемещени ми и радиальной силе устанавливают в шпиндельный узел остальные подшипники, нагружают вал шпиндел посто нной или переменной радиальной силой, измер ют его радиальное перемещение или амплитуду радиальных колебаний в точках, количество которых равно количеству подшипников, и по полученным данным рассчитывают радиальную жёсткость подшипников. - Переменную радиальную силу прикла дывают к валу шпиндел - с частотой не более 1,5 низшей собственной частоты шпиндел .The goal is achieved by installing the remaining bearings on the received movements and the radial force, loading the spindle shaft with a constant or variable radial force, measuring its radial movement or the amplitude of the radial oscillations at the points whose number is equal to the number of bearings the data obtained calculate the radial stiffness of the bearings. - Variable radial force is applied to the spindle shaft - with a frequency of not more than 1.5 of the lowest natural frequency of the spindle.
