Description

Oct. 24, 1961 F. w. BUTSCHER ADJUSTABLE SELF-CENTERING ROLL Filed March 24, 1959 /N 1 5 IV T0,? FRANK n. BUTSCHER iltliifi This invention relates to a self-centering roll and more particularly to a self-centering roll of the type disclosed in the patents to Lorig Nos. 2,593,158 and 2,817,940. The rolls disclosed in these patents depend upon deflection of their end sections. In designing such rolls the tension to be applied to the roll by the strip passing ther'eover is an important factor in determining the centering action. The rolls shown in the above mentioned patents do not have any means for adjusting the amount of deflection which can take place under variable strip tensions. The patent to Lorig No. 2,692,773 discloses a roll having means for adjusting the deflection. However, this adjustment is dependent upon a pl rality of tension bolts which must be individually adjusted to a common tension. This construction is expensive and the adjustment is dlflicult.
It is therefore an object of my invention to provide a self-centering roll which is provided with means for readily adjusting the amount of roll deflection.
This and other objects will be more apparent after referring to the following specification and attached drawings, in which:
FIGURE 1 is a sectional view of the preferred embodiment of my invention;
FIGURE 1a is an enlarged View of a portion of FIG- URE 1;
FIGURE 2 is a view taken on the line line 11-11 of FIGURE 1 with parts broken away and shown in section; and
FIGURE 3 is a sectional view of another embodiment of my invention.
Referring more particularly to FIGURES 1, 1c and 2, tie reference numeral 2 indicates coaxially opposed rotatable hollow cylinders over which a strip S passes in a direction transverse to the axes of the cylinders. Each of the cylinders 2 is provided with a radial web 4 at its outer end which is attached to a sleeve 6 in any manner providing for axial adjustment. As shown, this connection is a universal joint 8 but the web 4 could be attached directly to a ring 19 mounted on the sleeve 6. The universal joint 8 consists of three rings ill, 12 and 14. The ring ltl is attached to the sleeve 6 by means of a set screw 16. The outer ring 14 is welded to the web 4. The center ring 12 is pivotally attached to the outer ring 14 by means of diametrically opposed pins 13 and to the inner ring by means of diametrically opposed pins 2%) arranged at 90 from the pins 18. A locking pin 2.2 passes through each of the pins 18 and a similar locking pin 24 passes through each of the pins 26. Suflicient clearance is left between rings in and 12 and be tween rings 12 and 14 to permit tilting movement therebetween. A radial web 26 is fastened to the adjacent ends of the rims 2 and is provided With a bronze sleeve or hearing 28 held in position by means of set screws 30. Each of the sleeves 6 has a frusto-conic'al end 32 which is received in the opening in bushing 28. The sleeves 6 are hollow to receive a shaft 34 and are held in position thereon by means of set screws 38. This construction also enables the surface of both cylinders 2 to be machined after assembly.
The operation of the self-centering roll is essentially the same as that shown in the above mentioned patents with the universal joints 8 serving to compensate for tilting as shown in my copending application Serial No. 799,209, filed March 13, 1959 entitled Self-Centering Patented Got. 24, 1951 Roll. When it is desired to change the amount of deflection of the cylinders the set screws 16 and 33 are loosened and the sleeves 6 moved axially to the desired position after which the set screws 16 and 38 are tightened.
In the embodiment of my invention shown in FIGURE 3, each of the cylinders 2 is provided with a frustoconical inside surface 41) and each sleeve 6' is provided with a radial Web or flange 42 at its inner end. The construction is otherwise the same as that of the roll of FIGURE 1 and the adjustment for variable tension is essentially the same as that of the roll of FIGURE 1. The set screws 16 and 38 are loosened and the sleeves 6' are moved axially so as to vary the peripheral space or clearance between the surface 4t? and the web 42. Thus, in each embodiment a peripheral clearance is provided between an inner web and a frusto-conical surface, the amount of clearance being variable by moving a sleeve axially.
While two embodiments of my invention have been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
