Изобретение относитс  к области гидромашиностроени  и может быть использовано в рабочих колесах радиально-осевых гидромашин, преимупХественно гидротурбин .The invention relates to the field of hydraulic engineering and can be used in impellers for radial-axial hydraulic machines, mainly hydro turbines.

Известна радиально-осева  гидромашина , содержаш;а  верхний обод с разгрузочными отверсти ми, выполненными в виде секторных элементов, контактируюших между собой торцовыми поверхност ми 1. The radial-axial hydraulic machine is known, containing; and the upper rim with discharge openings made in the form of sector elements that are in contact with each other by the end surfaces 1.

Недостатком такого колеса  вл етс  трудоемкость выполнени  разгрузочных отверстий .The disadvantage of such a wheel is the laboriousness of making the discharge openings.

Цель изобретени  - уменьшение трудоемкости изготовлени .The purpose of the invention is to reduce the labor intensity of manufacture.

Это достигаетс  тем, что на торцовых поверхност х секторных элементов вдоль их хорды выполнены скосы, н разгрузочные отверсти  образованы последними смежных элементов.This is achieved by the fact that bevels are made on the end surfaces of the sector elements along their chord, and the discharge openings are formed by the last adjacent elements.

Иа фиг. 1 изображено рабочее колесо, продольный разрез; на фиг. 2 - то же, в плане.FIG. 1 shows the impeller, a longitudinal section; in fig. 2 - the same in terms of.

Рабочее колесо радиально-осевой гидромашины содержит верхний обод 1, состо щий из секторных элементов 2, имеюш,их .косы 3, выполненные вдоль хорды каждогоThe impeller of the radial-axial hydraulic machine comprises an upper rim 1 consisting of sector elements 2, i.e., their slopes 3, made along the chord of each

секторного элемента 2. Разгрузочные отверсти  4 образованы скосами 3 смежных секторных элементов 2.sector element 2. The discharge openings 4 are formed by bevels 3 adjacent sector elements 2.

Использование описываемого рабочего колеса радиально-осевой гидромашины позволит уменьшить трудоемкость выполнени  разгрузочных отверстий за счет упрощени  технологии изготовлени .Using the described impeller radial-axial hydraulic machines will reduce the complexity of the discharge holes by simplifying the manufacturing technology.
