Description
Изобретение относится к области компрессоростроения.The invention relates to the field of compressor engineering.
Наиболее близким к предлагаемому по технической сущности и достигаемому результату является составной диск рабочего колеса осевого компрессора, содержащий два соосных элемента [1The closest to the proposed technical essence and the achieved result is a composite disk of the impeller of an axial compressor containing two coaxial elements [1
Недостатком данной конструкции является узкая область применения и недостаточная надежность в работе. 'The disadvantage of this design is the narrow scope and lack of reliability. ''
Целью изобретения является повышение надежности в работе и расширение области применения составного диска рабочего колеса осевого компрессора.The aim of the invention is to increase reliability in operation and expand the scope of the composite disk of the impeller of an axial compressor.
Указанная цель-достигается тем, что в каждом элементе выполнена кольцевая проточка·, причем проточки обоих элементов образуют паз,в котором рас- и положен бандаж.Said aim is achieved in that in each element an annular groove ·, and both grooves form a groove elements, wherein the distribution and laid bandage.
На чертеже изображен диск рабочего колеса осевого компрессора, продольный разрез.The drawing shows a disk of the impeller of an axial compressor, a longitudinal section.
Составной диск рабочего колеса компрессора содержит два соосных элемента 1 и 2, в каждом из которых выполнена кольцевая проточка 3 и 4 соответственно. Проточки 3 и 4 обоих элементов 1 и 2 образуют паз 5, в котором расположен бандаж 6. Бандаж 6 выполнен из композиционного материала, например боропластика.The composite disk of the compressor impeller contains two coaxial elements 1 and 2, each of which has an annular groove 3 and 4, respectively. Grooves 3 and 4 of both elements 1 and 2 form a groove 5 in which the bandage 6 is located. The bandage 6 is made of composite material, for example boroplasty.
Сборку диска осуществляют следующим образом.The disk assembly is as follows.
Диск разрезают пополам в плоскости вращения на два элемента 1 и 2, во внутренних полостях которых выполняют кольцевые проточки 3 и 4. Наносят клей, бандаж 6 помещают в проточку 3 элемента I и '.закрывают элементом 2 с Доследующим соединением элементов 1 и 2 путем сварки.The disk is cut in half in the plane of rotation into two elements 1 and 2, in the internal cavities of which annular grooves 3 and 4 are made. Glue is applied, the bandage 6 is placed in the groove 3 of element I and '. Closed with element 2 with the subsequent connection of elements 1 and 2 by welding .
Такое выполнение диска позволяет снизить вес ротора компрессора в целом.This embodiment of the disk allows to reduce the weight of the compressor rotor as a whole.
