Abstract
The method for fixing the blade in the blade ring comprises the following steps: when manufacturing the blade, a groove corresponding to the diameter of the circular section of the fixing cable is milled in the blade body, then a groove corresponding to the diameter of the fixing cable is turned in the blade ring, then the starting opening is drilled in the blade ring and the contour of the blade is cut, then the blade with the milled groove is inserted into the ring, and finally the fixing cable is placed in place by bending a bar with a circular section into a circular shape.
Description
Technical field
The present invention relates to stator vane is fixed on method in the blade ring.
Background technique
Blade in the blade ring must be fixing in place after inserting.The present this two kinds of the most frequently used methods that are fixed with.
The first situation take the blade ring material than thick about 10% the fact of the needed final thickness of blade ring main body as the basis.The rounded material of strengthening is used to the ring (retaining ring) that turning goes out a square profile.Turning one groove on the remaining part of blade ring, this groove is deep into the main body of the blade that inserts.The square profile ring of institute's turning is inserted in the described groove with stator blade (Fig. 2).The shortcoming of this method is that retaining ring is to be made by the blade ring main body, and it has caused a large amount of wastes.In addition, this technique is time-consuming and be technology-intensive type, and it is so that fixing more expensive in the blade ring main body of blade.
It is to use lock pin that blade is fixed in the blade ring that the second has method (Fig. 3) now.In this case, each blade must be perforated, and is used for ring and vane hole that lock pin inserts coupling.This method also is that time-consuming and single step needs the workman.
Summary of the invention
According to the present invention, with antilift wire blade is fixed on method in the blade ring and is included in and mills out a groove corresponding with the diameter of the circular section of antilift wire at blade body during it is made.Then turning goes out a groove corresponding with the diameter of antilift wire on the blade ring main body, get out initial opening and cut the profile of blade at blade ring, the blade that then will have the groove of turning is inserted in the blade ring, at last antilift wire is settled (Fig. 1) in place.
The advantage of such scheme comprises blade ring needs is clamped and by the fact of turning again according to the present invention, and it is all finished after operation for the first time, and described antilift wire is the ordinary consumption article with minimum manufacture cost.This is showing huge economic advantages aspect material and the time saving when the turning blade ring.
Description of drawings
Will be explained in detail in the lower technological scheme of assisting of accompanying drawing, wherein:
Fig. 1 illustrates and uses the inventive method with fixing to blade of antilift wire.
Fig. 2 illustrates and uses the blade of the retaining ring of being made by the blade ring main body to fix.
Fig. 3 illustrates the blade of the use lock pin on the blade ring and fixes.
Embodiment
With antilift wire the method that blade is fixed in the blade ring is implemented as follows: when making blade 1, mill out a groove at blade body 1, this groove is corresponding with the diameter of the circular section of antilift wire 3, then turning goes out a groove that its diameter is corresponding with the diameter of antilift wire 3 on blade ring 2, then get out initial opening and cut the profile of blade 1 at blade ring 2, the blade 1 that then will have the groove of milling is inserted in the ring, at last antilift wire 3 is settled in placely, this is to be bent into ring by the bar rod that has a circular section with to realize.
The main body of blade ring 2 is thin about 10%, and the thickness that therefore is used for the material that blade ring 2 makes is corresponding with the final thickness that encircles 2.Turning goes out a groove in this main body, and the internal diameter of this groove is corresponding with the diameter of the circular section of antilift wire 3.Subsequently by this antilift wire 3 being pushed in the groove that passes blade body 1 and blade ring 2 main bodys and blade is fixed.The manufacturing of antilift wire 3 comprises does not cut described rope from the material that is used for the blade ring manufacturing with the rope bending.
Industrial applicibility
The present invention can be used for the fixing to prevent their movement of all types of turbo machines and compressor stator blade.
Claims (1)
1. with antilift wire blade is fixed on method in the blade ring, it is characterized in that, during blade is made, mill out a groove corresponding with the diameter of the circular section of antilift wire (3) at blade body (1), then go out a groove corresponding with the diameter of antilift wire (3) in the upper turning of blade ring (2), then get out initial opening and cut the profile of blade (1) at blade ring (2), the blade (1) that then will have the groove of milling is inserted in the ring, at last that antilift wire 3 arrangements are in place, this is to obtain by crooked one the bar rod with circular section.
