Изобретение относитс к машиностроению , к подшипниковым узлам.This invention relates to mechanical engineering, to bearing assemblies.
Цель изобретени - повышение надежности путем саморегулировани внутренних зазоров в подшипнике.The purpose of the invention is to increase reliability by self-adjusting internal clearances in the bearing.
На фиг. 1 изображен шарикоподшипниковый узел, с упругим элементом в виде тарельчатой пружины; на фиг. 2 - то же, с биметаллической тарельчатой пружиной.FIG. 1 shows a ball bearing assembly, with a spring element in the form of a cup spring; in fig. 2 - the same, with a bimetallic cup spring.
Шарикоподшипниковый узел состоит из корпуса 1, вала 2, шарикоподшипников 3 и 4, установленных на валу и в корпусе и ограниченных от перемеш.ений на валу стопорными кольцами 5, а в корпусе - стопорным кольцом 6 и крышкой 7.The ball bearing assembly consists of housing 1, shaft 2, ball bearings 3 and 4 mounted on the shaft and in the housing and limited from retaining the shaft on the shaft with retaining rings 5, and in the case with retaining ring 6 and the lid 7.
Наружные кольца подшипников выполнены составными из двух половин. Между половинами 8 и 9 кольца подшипника 3, и половинами 10 и II кольца подшипника 4 установлены втулки 12 и 13 соответственно. Втулки 12 и 13 выполнены из материала, имеюшего больший коэффициент линейного расширени , чем материал, из которого изготовлены половины наружных колец подшипников 3 и 4.The outer rings of the bearings are made up of two halves. Between the halves 8 and 9 of the bearing ring 3, and the halves 10 and II of the bearing ring 4 are installed bushings 12 and 13, respectively. Sleeves 12 and 13 are made of a material that has a greater coefficient of linear expansion than the material from which the half of the outer rings of bearings 3 and 4 are made.
Между шарикоподшипниками 3 и 4 с упором в половины 9 и 10 наружных колец установлен упругий элемент 14 в виде тарельчатых пружин (фиг. 1).Between the ball bearings 3 and 4 with an emphasis on half 9 and 10 of the outer rings, an elastic element 14 in the form of cup springs is mounted (FIG. 1).
На фиг. 2 упругий элемент 14 изображен- в виде биметаллических тарельчатых пружин .FIG. 2, the elastic element 14 is depicted in the form of bimetallic cup springs.
Узел работает следуюшим образом.The node works as follows.
При повышении температуры узла происходит увеличение всех его элементов, в том числе втулок 12 и 13.With increasing temperature node increases all its elements, including the sleeves 12 and 13.
При этом за счет того, что втулки 12 и 13 имеют коэффициент линейного расширени больший, чем половины 8 и 9 наружного кольца подшипника 3 и половины 10 и 11 наружного кольца подшипника 4, происходит смещение половины 9 кольца подшипника 3 вправо, а половины 10 кольца подшипника 4 влево, в результате чего достигаетс оптимальна величина зазора в подшипниках, а именно между шариками и дорожками качени половин наружных колец подшипников 3 и 4, что исключает заклинивание подшипникового узла при повышении температуры.In this case, due to the fact that the bushings 12 and 13 have a linear expansion coefficient greater than half of the 8 and 9 outer rings of the bearing 3 and half of the 10 and 11 outer rings of the bearing 4, half of the 9 rings of the bearing 3 move to the right, and half of the 10 bearing rings 4 to the left, resulting in an optimal clearance in the bearings, namely between the balls and the raceways of the half of the outer rings of the bearings 3 and 4, which eliminates the wedging of the bearing assembly as the temperature rises.
Упругий элемент 14 обеспечивает поджа- тие друг к другу втулки. 12 и половин 8 и 9The resilient element 14 ensures that the sleeves are pressed together. 12 and half 8 and 9

наружного кольца подшипника 3 с одной стороны и втулки 13 и половин 10 и 11 наружного кольца подшипника 4 с другой стороны.the outer ring of the bearing 3 on the one hand and the sleeve 13 and the halves 10 and 11 of the outer ring of the bearing 4 on the other hand.
Дл уменьшени усили поджати указанных элементов узла друг к другу при увеличении температуры может быть использована биметаллическа тарельчата пружина или винтова пружина сжати , выполненна из ферромагнитного материала.To reduce the effort of pressing these elements of the unit to each other with increasing temperature, a bimetallic spring or screw compression spring made of a ferromagnetic material can be used.
Применение предлагаемого узла позвол ет повысить надежность его работы путем саморегулировани внутренних зазоров в подшипниках.The application of the proposed unit allows to increase the reliability of its operation by self-regulating the internal clearances in the bearings.
