10 Claims.
This invention relates to roller blanks and the method of making rollers from said blanks.
' It is an object of this invention to provide novel blanks from which eccentric rollers may be quickly and economically fashioned.
A further object is to provide a method whereby eccentric rollers embodying inner cores or disks and outer rims may be produced inexpensively and with a minimum of operations.
Other objects of the invention Will become clear as the description thereof proceeds.
In the drawing forming part of this specification:
Figure 1 is a vertical section through a blank.
Figure 2 is a vertical section of roller rim obtained from the blank and ready for assembly into a roller.
Figure 3 is a vertical section of a roller core obtained from the blank and'prepared for assembly into a roller.
Figure 4 is an elevation of an eccentric roller.
Figure 5 is a vertical section taken on line 5--5 of Figure 4.
Referring to the drawing, Figure 1 thereof illustrates in section a novel forged blank from which the main portions of the eccentric roller illustrated in Figure4 of thedrawing are obtained. This blank designated in its entirety by the reference numeral ill is preferably forged although it will be understood that the blank is not necessarily limited to a forging. The blank I is prepared so as to present in a unitary structure defined core and rim portions H and I2. The circumference of the core II is indicated at [3 and the inner circumference of the rim I2 is shown at l4. Extending between these two circumferences and connecting the core and rim into a unitary structure is a connecting web l which as clearly appears in Figure 1 of the drawing is relatively thin. A similar web It may be formed in the core ll upon removal of which a preferably rectangular opening is provided in the core. If desired, however, the core I6 may be omitted from the blank and the rectangular opening herebeted as indicated at l8 and 19 for a purpose which will later appear.
In the removal of the rim and core from the blank Ill the connecting Web l5 may be cut away in order to separate the core H from the rim I2. The inner circumference of the rim is then. machined in order to remove the draft surfaces produced by the forging operation. In like manner the periphery of the core is machined to remove the draft surfaces and provide the rabbeted portions [8 and I9. Also the web 16 in the core is removed and the surfaces which it connects are machined. While this series of steps may be resorted to in properly removing the rim and the core from the blank and preparing them for assembly into a roller, it is preferred to chuck the blank in a machine in such a way that the core and rim portions of the blank will be prop erly supported so that the'removal of the webs I 5 and I6 and the machining of the inner circumference of the rim and the outer portion of the core may be performed in a single operation.
The prepared rim and core are assembled together with a roller bearing 20 to form the roller 2! illustrated'in Figures 4 and 5 of the drawing. It will be apparent from an examination of these figures that the rectangular opening I! is disposed eccentrically with respect to the center of the core thereby producing an eccentric roller. Where it is desired to produce a roller that is not eccentric the opening I! may, of course, be disposed concentric with the core. The roller bearing 20 comprises in addition to a series of rollers 22 a cage designated in its entirety by the reference numeral 23, portions of which are disposed in the rabbeted parts [8 and I9 of the core as illustrated in Figure 5 of the drawing.
It will be apparent that numerous changes and modification in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention, which is to be limited only by the scope of the claims appended hereto.
I claim:
1. A cylindrical blank for the production of an eccentric roller comprising a core and a rim may be produced, the inner portion of said blank being shaped to substantially the form of the core of said roller, the outer portion of said blank being shaped to substantially the form of the rim of said roller, and a web connecting said inner and outer portions of said blank.
2. A cylindrical forging for the production of an eccentric roller having a core and a rim, said forging comprising an inner and an outer por tion, a connecting web separating said portions, said inner portion being forged substantially to the form of the core of said roller and said outer portion being forged substantially to the form of the rim of said roller.
3. The method of producing an eccentric roller having a core and a separate rim comprising die forging a unitary blank to shape the inner portion of said blank to the form of said core and the outer portion of said blank to the form of said rim and provide a connecting web between said inner and outer portions, forming an opening in said core offset from the center thereof, removing said core and rim from said blank, machining the outer circumference of said core and the inner circumference of said rim and interposing an anti-friction bearing between said core and said rim.
4. A blank for the production of a roller having a core and a separate rim, said blank comprising inner and outer portions, said inner portion being shaped substantially to the form of the core of said roller and embodying a peripheral member and a relatively thinner web, the outer portion including inner and outer peripheral members and an intermediate member of reduced thickness and a web connecting said inner and outer portions of said blank.
5. A blank for the production of an eccentric roller having a core and a separate rim, said blank comprising inner and outer portions, said inner portion being shaped substantially to the form of the core of said roller and embodying a peripheral member and a relatively thinner Web, said peripheral member having a section of reduced thickness, the outer portion including inner and outer peripheral members and an intermediate member of Qi'educed thickness, and a Web connecting said inner and outer portions of said blank.
6. The method of producing a roller having separate core and rim members comprising subjecting a blank to a die forging operation to form simultaneously the shaped core member and shaped rim member of said roller, separating said core and rim members, machining the outer circumference of said core member, machining the inner circumference of said rim member and interposing an anti-friction bearing between said core and rim members.
7. The method of producing a roller having separate core and rim members comprising subjecting a blank to a die forging operation to form simultaneously the shaped core member and shaped rim member of said roller and a relatively thin web connecting said members, removing said web, machining the outer circumference of said core member, machining the inner circumference of said rim member and interposing an anti-friction bearing between said core and rim members.
8. The method of producing a roller having separate core and rim members comprising subjecting a blank to a die forging operation to form simultaneously shaped core member and shaped rim member of said roller and a relatively thin web connecting the outer circumference of said core member with the inner circumference of said rim member, simultaneously removing,
said connecting web and machining said circum-- ferences of said core and rim members and inter posing an antifriction bearing between said core and rim members.
9. The method of producing a roller having separate core and rim members comprising simultaneously shaping said core and rim mem-' bers by a forging operation in asingle forging die, separating said core and rim members, ma-
cjnining the outer circumference of said core member, machining the inner circumference of said rim member and assembling said members into said roller.
10. A blank for the production of a roller having separate core and rim members, said blank comprising a unitary structure having an inner portion embodying a Web and relatively thicker oppositely extending circular flanges projecting from said web and forming the core member of said roller, and an outer portion including spaced oppositely extending circular flanges and an intermediate relatively thinner Web and forming the rim of said roller, said inner and outer portions being formed into said unitary structure by a relatively thin connecting Web, said flanges of said inner portion being of increased Width below the center of the web of said inner portion and including a section of reduced thickness.
