BLADED ROTOR AND THE LIKE FOR AXIAL FLOW FLUID MACHINES Filed June 4, 1958 IN V EN TOR.
United States atent ()fitice 3,006,605 BLADED ROTOR AND THE LIKE FOR AXIAL FLOW FLUID IJACHINES Edward A. Stalker, 406 N. Farragut St., Bay City, Mich. Filed June 4, 1958, Ser. No. 739,332 6 Claims. (Cl. 253-77) My invention relates to bladed rotors and the like for axial flow compressors, turbines and the like.
An object of my invention is to provide an economical and light weight rotor particularly adapted to sheet metal construction.
Another object is to provide a rotor wherein the joints are readily inspectable.
Still another object is to provide a bladed structure wherein the blades are supported on a single disk by a simple connection.
Other objects will appear from the specification, appended claims, and accompanying drawings.
The above objects are accomplished by the means illustrated in the accompany drawings in which FIG. 1 is an axial view of a fragment of a rotor according to the subject invention;
FIG. 2 is a fragmentary section on line 22 in FIG. 1;
FIG. 3 is a fragmentary section on line 3-3 in FIG. 2;
FIG. 4 is a section on line 44 in FIG. 2;
FIG. 5 is a fragmentary section on line 5-5 in FIG. 2;
FIG. 6 shows a fragment of the inner end of a hollow blade with the legs spread apart before engagement with the disk of the rotor; and
FIG. 7 shows a fragment of the inner end of a blade whose legs are integral with the blade surface and spread apart before engagement with rotor disks.
In this invention the blade may be solid or composite with a stem bonded interiorly of the blade shell. Such a composite blade will usually be hollow. The stem extends radially inward through the rim means and engages the rim mechanically. It may also be bonded to the disk by fused metal, braze metal for instance.
Referring now to the drawings the rotor is indicated generally by 10. It comprises the blade 12 and the hub means 14.
The hub means 14 comprises the hollow rim means 16 and the rotor blade central support disk 29 positioned between the leading and trailing edges of the blades.
The blades are spaced peripherally, FIGS. 1 and 3, and each comprises a blade shell and a root portion integral therewith preferably of a thicker wall than the shell. The root portion fairs into the shell by a generous fillet, and a stem 22 fixed internally of the blade and extending radially inward through the rim of the rim means to a junction with the rotor disk for support thereby.
The stem has the two legs 23 and 24 which have the tenons 30 and 32, FIGS. 1, 2 and 5, which pass through openings 34 in the disk. These are peripherally spaced about the support disk. The tenons fit closely to the sides of the openings and to each other in side by side relation.
Each leg preferably bears on the disk whichis re ceived between them and is preferably bonded thereto by fused metal preferably braze metal. The stem and disk form a simple light structure capable of supporting the blade against the forces arising from its rotation in use. The disk may also be reinforced by a ring 46 bonded to the disk.
The disk preferably has peripherally spaced notches in its periphery into each of which the inner end of the root portion of a blade fits and is preferably bonded to give additional side support to the blade means.
The rim means comprises the rim segments 42 between blades at their root portions (see FIGS. 1 and 3), the rim side rings 44 and 46, and the angles 47 and 48 fixed to the rim segments and preferably bonded to the root portions of the blades. Preferably the rings have flanged openings 50 for stiffening the rings and for acess to the legs and joints of each stem with the hollow rim means which is closed to radial view by the peripheral portions of the disk.
The rim means extend from front to rear of the rotor and from blade to blade to sustain variations in fluid pressure. The rim means is secured to the disk for support thereby.
The disk is metal to provide rigidity and homogeneous strength properties in all radial directions so that it can support the blades bearing against the radially outward sides of the disk holes for support against the centrifugal forces. The disk is prepierced with generally rectangular holes directed radially, that is having their major dimension along the radius. The tenons would have a cross section at the disk conforming to the shape of the holes. This rectangular cross section is necessary to provide adequate shear strength in the tenon. Thus adequate strength is provided while retaining the low cost feature of a generally flat root portion of the blade including the legs and tenons.
The stem is first formed with the legs spread apart as shown in FIG. 6 providing a gap 54 just large enough for the stem to straddle the disk. The legs are then pressed toward each other and through the hole in the disk.
The blades may have the legs integral with a blade surface including that of a solid blade with tenons formed in the legs as shown in FIG. 7. The tenons are to engage the disk in the same manner as of FIGS. 2 and 5.
The disk may be attached to a shaft means 57 by bolts 58 spaced peripherally about the disk, for instance. The rotor rotates with the shaft about the axis of symmetry of the rotor or disk.
It will now be clear that I have provided a light weight and economical rotor. The blades are simple to make since they require no costly and heavy machined rotor rims. Furthermore the connections of the blades to the disk are easily inspected.
While I have illustrated specific forms of the invention, it is to be understood that variations may be made therein and that I intend to claim my invention broadly as indicated by the appended claims.
