Изобретение относитс к области эпектромашйностроени , в частности к вертикальным электрическим машинам, гидрогенераторам.The invention relates to the field of machine building, in particular to vertical electric machines, hydrogenerators.

Известен подшипниковый узел вертикальной электрической машины, содержащий подп тник,. мал ную ванну, корпус, охладители l . Недостатком таких конструкций вл етс нх значительный вес.A bearing unit of a vertical electric machine, containing a bogie, is known. small bath, body, coolers l. The disadvantage of such structures is their nx weight.

Известен также подшшшиковый узеп вертикальной электрической машины, например гидрогенератора, содержащий копус , регулируемые креп щие элементы, подп тник и масл ную ванну с днищем, о.хладител ми и уплотнени ми 2 .Also known is an underside of a vertical electric machine, such as a hydrogenerator, containing a copus, adjustable fasteners, a base plate, and an oil bath with a bottom, coolant and seals 2.

Масл на ванна с установленным в ней подп тником опираетс через промежуточную подставку на крышку турбины. Непосредственно корпус подп тника с ег опорны1Ли, регулируемыми, креп щими элементами и несущими сегментами расположены вблизи, внутреннего диаметра днища и, как правило, занимают внутреннюю часть радиального сечени дни,ща.The oil in the bath with the bushing installed in it is supported through an intermediate support on the turbine cover. Directly the body of the bolster with its support, adjustable, fastening elements and carrier segments are located close to the internal diameter of the bottom and, as a rule, occupy the internal part of the radial section of the ground.

Следоватеньно, и обща осева нагрузка, приход ща с на подп тник, передаетс только на эту часть днища. На внешнюю часть днища прн-ходитс нагрузка,.равна только общему количеству установленных в данной ванне маслоохладителей вместе с наружной стенкой и частью масла. Вес этих вместе вз тых частей составл ет приблизительно одну сороковую часть от веса, приход щегос непосредственно на подп тник и внутреннюю часть днища,Consequently, the total axial load, which comes to the support, is transmitted only to this part of the bottom. The load is applied to the outer part of the bottom. It is equal only to the total number of oil coolers installed in the bath together with the outer wall and part of the oil. The weight of these parts taken together is approximately one fortieth part of the weight directly on the bedplate and the inside of the bottom,

Целью изобретени вл етс уменьш&нйе весомых .характеристик узла.The aim of the invention is to reduce & significant node characteristics.

Указанна цель достигаетс тем, что днище ванны выполнено в виде внутреннего кольца, и сопр женного с ним по периферий ненужного кольца меньшей толщины, соединенного с внутренним неразъемно.This goal is achieved by the fact that the bottom of the bath is made in the form of an inner ring, and an unnecessary ring of thickness that is adjacent to it along the periphery of the unnecessary ring, which is connected to the inner one.

На чертеже представлен подшипниковый узел, продольный разрез.The drawing shows the bearing unit, a longitudinal section.

Claims

The bearing assembly contains an oil bath 1 having a bottom, made of an inner ring 2 and a patch outer ring 3, mating with the ring 2 on the periphery one-piece. In order to save metal, the outer ring 3 is made of thinner sheet steel (for example, three times) than the inner one, which carries the main load from rotating parts of the generator, turbine and water reaction. The vertical wall is attached to the outer diameter of the ring 3 by the windows. 5 for installing and fixing oil coolers therein 6. On the upper end part of the wall 4 there is a flange 7 on which covers 8 and a seal 9 are secured. a vertical wall, a lid with seals and a fence create the necessary volume of oil bath 1, in which. On the upper plane of the inner ring 2, the foaming pin C is installed and closed. In the free volume of the pin, in order to ensure its operation, there is lubricating oil 12, which is filled to the required level. The assembled oil on the bath with bolster is supported and fixed on a special support 13 placed on the turbine cover. Segments 14 of the subframe are located on the disk 15, which is connected to the sleeve 16. The latter is attached to the sleeve 17 of the generator rotor core. The turbine shaft 19 extending inside the cylinder-wall enclosure 10 is connected to the inner lower flange 18 of the rotor core. Making the bottom of the oil bath of the bearing assembly a composite of two rings of different thicknesses reduces the weight characteristics of the assembly by reducing the machine load of the less loaded outer ( Claims of the Invention A bearing assembly of a vertical electric machine, for example, a hydrogenerator, comprising a housing, adjustable fastening elements, a support and an oil bath with a bottom, cooling coax and a pack By means of which the specified stopper is installed, characterized in that, in order to reduce the balance of the characteristics, the bath is made in the form of an inner ring and a lesser top-region adjacent to it along the periphery of the inner one, which is connected to the inner one. , taken into account during the examination 1.Kostenko MP, Sukhanov L, A., Aksenov V, I, Modern powerful hydrogenerators, - M., ed., Informstandartlectro, 1967, 2, Zundelevich M, I., Prutkovsky S , A.
