Изобретение относитс к области турбостроени .The invention relates to the field of turbine construction.
Известны устройства дл уплотнени рабочих лопаток турбины, содержащие установленную в подошве замка контровочную пластину с отогнутыми концами.Devices are known for compacting turbine blades containing a locking plate with bent ends installed in the lock sole.
Предлагаемое устройство отличаетс от известных тем, что в нем ширина отогнутого вверх конца пластины выполнена большей, чем ширина замковой части лопатк}, а его верхний край установлен в пазу под полкой лопатки.The proposed device differs from the known ones in that the width of the plate bent upward side is larger than the width of the blade part}, and its upper edge is installed in the slot under the blade shelf.
Такое вйполнение устройства позвол ет уменьшить утечки.Such a device can reduce leakage.
На фиг. 1 показан вид спереди диска с лопатками; на фиг. 2 -продольное сечение предложенного устройства; на фиг. 3 - общий вид уплотнени .FIG. 1 shows a front view of a blade disc; in fig. 2 is a longitudinal section of the proposed device; in fig. 3 is a general view of the seal.
Устройство дл уплотнени рабочих лопаток 1 турбины представл ет собой контровочную пластину 2, установленную в подошве замка 3. Пластина 3 в сборе с лопатками 1 имеет отогнутые в противоположные стороны копцыThe device for sealing the working blades 1 of the turbine is a locking plate 2 mounted in the sole of the lock 3. The plate 3 assembled with the blades 1 has tail bent in opposite directions
4 и 5. Причем верхний конец 5 пластины 2, отогнутый заранее под углом сответствующим торцу пожки лопатки, выполнен так, что его ширина больше, чем ширина замковой части лопатки, и установлен в пазу под полкой лопатки .4 and 5. Moreover, the upper end 5 of the plate 2, bent in advance at an angle corresponding to the end of the blade, is made so that its width is greater than the width of the locking part of the blade, and is installed in a groove under the blade shelf.
Кроме того, дл уменьшени утечек воздуха через зазоры между торцами пластин возможно их выполнение несимметричными со стыком на ножке лопатки.In addition, to reduce air leaks through the gaps between the ends of the plates, it is possible to make them asymmetrical with a junction on the blade blade.
Предмет изобретени Subject invention
