Description
После заведени всех лопаток, в том числе и замковой, в замковый вырез завод т верхнюю вставку 7, а затем на штифты 3 надевают нижнюю вставку 4 (штифты 3 служат дл фиксации вставки 4 в осевом направлении). Далее устанавливают стопорные планки 6 и с нат гом в радиальном направлении завод т среднюю вставку 5. С нротивоположиого торца диска в тангенциальную прорезь устанавливают стопорные планки 9 и завод т с нат гом в радиальном направлении вставку 8. Дл предотвращени осевого смещени вставок 5 и 8 необходимо концы стопорных планок 6 и 9 отогнуть к поверхности диска.After inserting all the blades, including the locking, into the locking notch, the upper insert 7 is inserted, and then the lower insert 4 is put on the pins 3 (the pins 3 serve to fix the insert 4 in the axial direction). Next, the locking strips 6 are installed and, with a tension in the radial direction, the middle insert 5 is inserted. At the opposite end of the disk, the locking strips 9 are installed in the tangential slot and the insertion 8 is fitted with a tension in the radial direction. To prevent axial displacement of the inserts 5 and 8, the ends of the locking bars 6 and 9 bend to the surface of the disk.
При разборке замкового соединени необходимо выпр мить концы стопорных планок 6 и 9, отжимными винтами, вворачиваемыми в отверсти а и б, удалить вставки 5 и 8, затем удалить стопорные планки 6 и 9 и при помощи клиньев, вставленных в щели в и г, последовательно удалить вставки 7 и 4. После разборки указанных деталей удал ют замковую лопатку 1. When disassembling the locking joint, it is necessary to straighten the ends of locking strips 6 and 9, squeezing screws, screwed into holes a and b, remove inserts 5 and 8, then remove locking strips 6 and 9 and using wedges inserted into slots c and d, sequentially Remove inserts 7 and 4. After disassembling these parts, the locking blade 1 is removed.
Предмет изобретени Subject invention
Замковое соединение рабочих лопаток, преимущественно экспериментальной турбомашины , содержащее замковую лопатку, выполненный в одной из щек обода диска тангенциальный наз и фиксирующий элемент дл кренлени замковой лопатки, отличающеес тем, что, с целью обеспечени возможности установки в диске разного числа лопаток, в другой щеке обода выполнена соосна пазу прорезь, а фиксирующий элемент выполнен в виде укрепленных в прорези одной и в пазу, по крайней мере, трех вставок.A lock joint of working blades, predominantly an experimental turbomachine, containing a lock blade made in one of the cheeks of the rim of a disk tangential called and a fixing element for heeling the lock blades, characterized in that, in order to allow installation of a different number of blades in the disk, in the other cheek of the rim the slot is aligned with the groove, and the locking element is designed as one slot in the slot and at least three inserts in the slot.
