Abstract
Изобретение относитс к вентил торостроению и может быть использовано в рабочих колесах центробежных вентил торов. Цель изобретени - повышение надежности. В покрывном 1 и несущем 2 дисках выполн ют прорези и углублени , образующие с их внешней стороны козырьки 4, открытые как со стороны прорезей, так и с противоположной стороны. Выступы 6 лопаток 5 размещают в прорез х дисков 1, 2 путем введени их в прорези со стороны углублений и фиксируют выступы 6 путем обжати козырьков 4. Выполнение козырьков 4 открытыми и со стороны, противоположной прорез ми, позвол ет обжимать козырьки 4 заподлицо с дисками 1, 2 колеса, что повышает его надежность. 5 ил.This invention relates to a fan construction and can be used in impellers of centrifugal fans. The purpose of the invention is to increase reliability. In the cover 1 and carrier 2 disks, slots and grooves are formed, forming peaks 4 on their outer side, which are open both on the side of the slots and on the opposite side. The protrusions 6 of the blades 5 are placed in the slots of the disks 1, 2 by inserting them into the slots from the side of the recesses and fixing the projections 6 by squeezing the visors 4. Making the peaks 4 open and from the side opposite to the slots allows crimping the peaks 4 flush with the disks 1 , 2 wheels, which increases its reliability. 5 il.
