Description

РГзобретение относитс к области маиипюстроени , в частности к иодшиппиковым узлам, содержащим систему смазки.The invention relates to the field of engineering, in particular, to the bearing units containing a lubrication system.

Известен подшипииковый узел с вертикальным валом, содержании подшипни1 качени и систему смазки, состо нлую из винтового масл ного насоса с ротором, напорной камеры и каналов нодвода смазки к подшипнику качени 1.A bearing assembly with a vertical shaft, a rolling bearing maintenance and a lubrication system, consisting of a screw oil pump with a rotor, a pressure chamber and lubrication channels to the bearing 1, are known.

Недостатком известного устройства вл етс невысокий срок службы подшипников и большие затраты на его обслуживание вследствие смазки иодшипников маслом , загр зненным продуктами износа под1НННИИКОБ , продуктами разложени масла и други.мн посторонними частицами.A disadvantage of the known device is the low service life of bearings and the high cost of maintaining it due to the lubrication of the bearings with oil contaminated with wear and tear products, oil decomposition products and other particles.

Целью изобретени вл етс увеличение срока службы подшипниковых узлов и уменьшение затрат на обслул ивание.The aim of the invention is to increase the service life of the bearing assemblies and reduce maintenance costs.

Цель достигаетс тем, что подшипниковый узел механизма с вертикальным валом , содержащий подшипник качени и систему смазки, состо щую из винтового масл ного насоса с ротором, напорной камеры и каналов подвода смазки к подшипнику , снабжен кольцами, стаканом и дискол-г ири этом одно из колец установлено между дном напорной камеры и торцом ротора насоса, который выполнен с центральным отверстпем, внутри которого разMcuieu стакан с центральным отверстием в дне и параллельно расположенные и естко соединенные между собой диск и другое кольцо.The goal is achieved by the fact that the vertical shaft bearing assembly, which contains a rolling bearing and a lubrication system consisting of a screw oil pump with a rotor, a pressure chamber and channels for supplying lubricant to the bearing, is equipped with rings, a cup and a discolouri the rings are installed between the bottom of the pressure chamber and the end of the pump rotor, which is made with a central hole, inside which is a glass cup with a central hole in the bottom and parallel to the disk and another ring arranged parallel to each other about.

Устройство содержит подшипник /, ка .иалы 2 дл подвода смазки, выполненные в подшипниковом щите 3 или в вале 4, напорную камеру 5, винтовой масл ный на15 сое, ротор 6 которого насажен на вал /. В центральном отверстии 7, выполненном в роторе 6 насоса, размещен стакан 8 с центральным отверстием в дне, создающий вращающийс слой масла и направл ющийThe device contains a bearing (1) for supplying lubricant, made in a bearing shield 3 or in shaft 4, a pressure chamber 5, a helical oil oil 15 soy, the rotor 6 of which is mounted on the shaft /. In the central hole 7, made in the rotor 6 of the pump, there is a glass 8 with a central hole in the bottom, creating a rotating layer of oil and a guide

20 его движеиие. Со стороны торца ротора 6 в отверстие 7 встроен элемент 9, состо щий из соединеиных между собой диска и кольца, расположенных параллельно плоскости торца ротора 6. Элемент 5 распредел ет вход щий поток, направленный по оси вращени , по радиальным направлени м. Между диом напорной камеры 5 н ториом ротора 6 установлено кольцо 10, облегчающее вход масла в отверстие 7 ротора 620 of his movement. From the end of the rotor 6, an element 9 is built into the hole 7, consisting of a disk and a ring interconnected parallel to the plane of the end of the rotor 6. The element 5 distributes the incoming flow, directed along the axis of rotation, in radial directions. camera 5 n thorium rotor 6 installed ring 10, facilitates the entry of oil into the hole 7 of the rotor 6

Claims

30 for centrifugal cleaning. The device operates as follows: after starting the mechanism, the pump generates an increased pressure in the pressure chamber 5, from which the oil enters the bearing through channels 2 /. When lubricating the underside, through the bearing rod, IT 3 (Fig. 1), one part of the oil directly from the pressure chamber 5 through the channels 2 enters the bearing I, and the other part goes into the glass 8 for centrifugal cleaning, flows through the iW ring, contributes forming an uncoiled layer of oil and thus facilitating its entry of oil thrown off by a rotating rotor, and passage through element 9, preventing the passage of oil without purification due to the distribution of the incoming flow, directed along the axis of rotation, in radial directions. When the oil inside the cup 5 is rotated, particles of impurities are deposited on its walls, and clean oil is ejected into the pressure chamber 5 through the central hole in the bottom of the cup 8 and further through the gap between the end of the rotor 6 and the ring of the element 9. When the bearing is lubricated / shaft 4 (fig. 2) the oil is immediately subjected to centrifugal cleaning in the hole of the rotor 6, it also penetrates through the ring 10 and the element 9. The invention allows to increase the service life of the nodelyniki nodes and reduce the service time due to continuous centrifugal cleaning oil tk. Claims of the invention A vertical shaft bearing assembly comprising a rolling bearing and a lubrication system consisting of a screw oil pump with a rotor, a pressure chamber and channels for supplying lubricant to a bearing, characterized in that in order to increase bearing life and reduce costs maintenance, the bearing unit of the mechanism is equipped with rings, a cup and a disk, while one of the rings is installed between the bottom of the pressure chamber and the end of the pump rotor, which is made with a central hole, inside which placed a glass with a central hole in the bottom, and parallel to the spaced and rigidly interconnected disk and another ring.
