Description
Известные гибкие бандажи дл демпфировани вl бpaциii турбнпных лопаток, состо щие из металлической ленты, укрепленной на концах лонаток турбины шипами-заклепками и охватывающие все лопатки по окружности, не позвол ют устран ть вибрацию лопаток при перво.м тоне колебаний в тангенциальном направлении из-за жесткого креплени бандажа к лонаткам.Known flexible bandages for damping of the turbine blade blades, consisting of a metal tape fixed to the ends of the turbine arms with spiked rivets and covering all the blades around the circumference, do not allow vibration of the blades at the primary tone of oscillations in the tangential direction due to rigid attachment of the brace to the curb.
Бандаж, выполненный согласно изобретению, лишен этого недостатка .The bandage, made according to the invention, is devoid of this disadvantage.
Сущность изобретени состоит в том, что бандаж выполнен из гибкой ленты и укреплен с радиальным и тангенциальными зазорами ме/кду гибкой лентой и типами-заклепками.The essence of the invention is that the bandage is made of flexible tape and reinforced with radial and tangential gaps me / kdu flexible tape and types of rivets.
На фиг. 1 схематически изображен общий вид креплени к лопатке в двух проекци х; на фиг. 2 - крепление многослойного бандажа к лопатке; на фиг. 3 - крепление бандажа, снаб.кенного отбуртовкой .FIG. 1 shows schematically a general view of attachment to a blade in two projections; in fig. 2 - fastening of the multilayer band to the blade; in fig. 3 - fastening of the bandage, provided with a stand-off.
Гибкий бандаж / представл ет ;еталлическую ленту, выполненную из одной или нескольких полос, укрепленную на концах лопаток 2 турбнны шипами-заклепками 3 н охватывающую все лопатки по окружности . Дл устраненн вибрации лопаток нри первом тоне колебаний в тангенциальном направлении бандаж 7 укреплен на лопатке 2 с радиальными и тангенциальными зазорами между гибкой лентой бандажа / и типами-заклепками 3.Flexible bandage / represents; etalic tape, made of one or several strips, fastened on the ends of the blades 2 of the turbine with 3-n spikes-rivets covering all the blades around the circumference. To eliminate the vibration of the blades in the first tone of oscillations in the tangential direction, the band 7 is fixed on the blade 2 with radial and tangential gaps between the flexible band of the band / and the rivet types 3.
Центральный научно-исследовательский котлотурбикный ИНСТИТУТ им. И. И. Ползунова отмечает промышленную полезность предложенного устройства.Central Research Klotloturbik INSTITUTE them. I. I. Polzunova notes the industrial utility of the proposed device.

Гибкий бандаж, демфирующий вибрацию турбинных лопаток, состо щий из металлической-ленты, укрепленной-на-концах лонаток тур№ 141041A flexible bandage that dampens the vibration of turbine blades, consisting of metal-tape, reinforced-at-the-ends of the tarpaulin tour No. 141041
бины шипами-заклепками и охватывающий все лопатки по окружности , отличающийс тем, что, с целью создани возможности перемещени массы ленты и ее трени при ьибрации лопаток в танге)циальном направлении, бандаж выполнен из гибкой ленты и укреплен с радиальными и тангенциальными зазорами между гибкой лентой и шипами-заклепками.Spike-rivet bins and covering all the blades around the circumference, characterized in that, in order to create the possibility of mass movement of the tape and its friction when bending the blades in the tanga direction, the bandage is made of flexible tape and reinforced with radial and tangential gaps between the flexible tape and spiked rivets.
