Description

Предлагаемое устройство дл  закреплени  рабочих лопаток на диске паровой турбины основано на круговом замыкании и не требует Т-образного замыкани  на диск.The proposed device for fixing the working blades on the steam turbine disk is based on a circular closure and does not require a T-shaped closure to the disk.

На чертеже фиг. 1 изображает общий вид креплени  лопаток на диске дл  случа  с призматическими выступами; фиг. 2 и 3-его поперечный разрез по вертикали , причем на фиг, 3 прин то во внимание видоизменение данного устройства .In FIG. 1 shows a general view of the attachment of blades to a disk for a case with prismatic protrusions; FIG. 2 and 3 is a vertical cross-section, and in FIG. 3, the modification of this device is taken into account.

Одна сторона ножки лопатки снабжена призматическим или полукруглым выступом 5, а друга  сторона - соответствующим углублением 4. При облопачивании диска лопатки располагаютс  таким образом, чтобы сторона ножки лопатки с выступом примыкала к вогнутой стороне соседней лопатки, а сама  лопатка примыкает к конически заточенному диску скошенной поверхностью 2 и нажимаетс  к нему кольцом 1, укрепленным заплечиками.One side of the blade foot is provided with a prismatic or semi-circular protrusion 5, and the other side with a corresponding recess 4. When blading the disk, the blades are positioned so that the side of the blade leg with the protrusion adjoins the concave side of the adjacent blade, and the blade itself adjoins the conically sharpened disk with a beveled surface 2 and pressed to it by a ring 1, reinforced by shoulders.

На фиг. 3 показан вариант устройства креплени  лопаток, который отличаетс  тем, что нажимное кольцо 1 располагаетс  с противоположной стороны заточки и скрепл етс  с ножкой 2 лопатки заклепкой 3,FIG. 3 shows a variant of a blade attachment device, which is characterized in that the pressure ring 1 is located on the opposite side of the sharpening and is attached to the blade foot 2 by a rivet 3,
