ROTOR FOR VIBRATOR buns Filed Oct. 3, 1944 INVENTO WILLIAM P. DA
Patented Mar. 23, 1948 ROTOR FOR VIBRATOR UNITS William P. Day, Cleveland Heights, Ohio, assignor to The International Vibration Company, Cleveland, Ohio, a corporation of Ohio Application October 3, 1944, Serial No. 557,002
1 Claim. 1
This invention relates to a rotor for vibrator units and a method of making the same. Broadly speaking, the invention comprehends theproduction of a rotor for a vibrator unit at a low cost in such a manner as to eliminate much labor and many operations.
Heretofore rotors oi this type have been made in several pieces which require a number of machining operations as well as considerable time and labor for'assembling. I propose to eliminate many of these operations and at the same time to produce a more satisfactory rotor.
One of the objects of the invention is to provide a rotor for vibrator units of any character which consists essentially of inner and outer parts, the outer part being circular and cast about the inner part which is axially ofiset or eccentrically positioned with respect to the inner part.
Another object of the invention is to provide a rotor of the character described in which the peripheral surface of the outer part is shaped or machined to provide a turbine wheel.
Another object of the invention is to provide a rotor of the character described which is well adapted for quantity production at comparatively low cost.
Further and more limited objects of the invention vw'll appear as the description proceeds and by reference to the accompanying drawings in which Fig. 1 is a top plan view of my improved rotor with a part shown in section;
Fig. 2 is a vertical sectional view on the line 2--2 of Fig. 1;
Fig. 3 is a top plan view of the inner or offset part of the rotor;
Fig. 4 is a view in side elevation of the part shown in Fig. 8;
Fig. 5 is a sectional View onthe line 5-5 of Fig.
Fig. 6 is a vertical sectional view of my improved rotor in which the peripheral surface is left smooth; and
Fig. 7 is a fragmentary detail view in elevation disclosing the shape of the recesses in the peripheral face of the turbine.
Referring now to the drawings, the reference character I designates the inner part of the rotor which .is shaped as shown most clearly in Figs. 3 and 4. This part is preferably formed of steel or some other rather heavy metal. This part is preferably, though not necessarily, semi-circular in shape and has a shaft 2 formed integral therewith. Extending about the peripheral portion of this part are a plurality of grooves 3, the purpose of which will hereinafter appear. The inner part of the rotor is surrounded by an outer circular part 4 which is cast about the inner part I. The part 4 is formed of a metal substantially lighter than the inner part, such as magnesium or the like. The inner part is preferably made of a drop forging and may have a shape other than that illustrated. However, I do not wish to be limited to any particular material for either part. The peripheral surface of the outer part is provided with a plurality of recesses which may be formed on a milling machine. The grooves 3 serve to provide a firm interlock between the two parts.
After the inner part has been formed and machined,-it is placed within a suitable mold or flask and properly supported therein. The outer part is then poured over the inner part and allowed to cool in a manner well known to those skilled in the art.
The form of the invention shown in Fig. 6 is identical with that shown in the remaining figures except that the peripheral portion of the outer part is given a smooth finish and the recesses are omitted. This form of rotor is adapted to be electrically driven. It is to be understood that the rotor in either case is mounted in a suitable casing and provided with the proper bearings. If desired, the outer lighter part may be formed first and provided with an opening to receive the shaft therethrough and also provided with one or more cavities of the desired size and located at the proper place, and the heavier metal poured into such cavity. If desired, the shaft may be formed integral with the outer or lighter part.
It will now be clear that I have provided a rotor for use in vibrator units that will accomplish the objects of the invention as hereinbefore stated. The embodiment of the invention herein disclosed is to be considered merely as illustrative and not in a limiting sense as various changes may be made in the shape, size and arrangement of parts as well as in the materials used without departing from the spirit of the invention. The invention is therefore limited only in accordance with the scope of the appended claim.
Having thus described my invention, what I claim is:
A rotor for vibrator units comprising an inner portion, and a circular portion cast about said inner portion, said two portions being eccentrically disposed and said inner portion being formed of a heavier material than said outer portion, said outer portion having its peripheral surface recessed to provide a turbine wheel, said inner portion having a shaft formed integral therewith and extending on opposite sidesthereof.
