My invention relates; to rolling mil-ls andmore particularly to the housings in which the rolls are mounted. Of late, such housings have been so designed as to provide for a direct drive of the '5- rolls by electric motors. The purpose of this construction was to make the moving masses as small as possible, which object toa certain degree was fully attained. There is, however, a serious drawback to such constructions in that the accessibility of the rolls is considerably hindered by the housings themselves.
The object of the present invention is to make the, rotating masses still smaller and at the same time, to considerably improve the accessibility of the rolls, while, in addition, afiording far greater possibilities of arrangement in the disposition in space ofthe continuously and successively oper-.
ating roll housings. novel housing construction and disposition rolls are attained.
For a fuller understanding of my invention, I refer to the annexed drawing, on which, by way l of illustration, I have shown an embodiment of my invention and on which drawing Fig. 1 is a vertical sectional view through a roll-housing embodying the invention, Fig. 2 a' transverse section perpendicular to the plane of Fig. 1, Fig. 3 a front elevation of two adjacent roll housings as seen toward the ends of the rolls, and Fig. 4 a horizontal sectional view of the top roll. Fig. 5 is a section through the adjusting means for raising and lowering the upper roll, while Fig. 6 is a section through the mechanism for the axial adjustment of the said roll. On the drawing are shown at l and 2 the overhung rolls carried by the axes 3 and 4 respectively which, at the same time, constitute the shafts of the corresponding electric driving motors, each motor comprising a rotor, 5 and 6 respectively, and wound stators, 1, 1 and 8, 8 respectively. The stators, as shown, are disposed on either side of the rotors. As will be seen, the
In this manner, an entirely of stators have no larger dimensions in the direction toward each other than the radius of the rotors. At 9 is shown the casing enclosing the motor for the upper roll, I, while casing constitutes the top part of the roll-housing, while the motor for the lower roll 2 is enclosed in a casing constituting the bottom part of the housing. Casing 9, as is shown more clearly in Fig. 2 is formed with an offset flange H which overlaps the upper rim of casing [0 thus preventing any water or dirt from entering the housing. At I2 is shown the cap of the housing which is carried by four vertical columns l3, l4, l5 and, I6, which extend through the twocasings 9 and I0 and are inserted in the baseplate ll. The upper. casing 9,is,he1d in complete balance bythe; elastically suspended straps l8 and I9. Pressure exerting members are indicated at 20 and 2t with which cooperate adjusting disks shown at 22 and 23 to accurately position the upper roll; IJ relative. to the lower roll 2 by means of the casing 9 carrying the upper roll I.
At 24 is shown another adjusting disk which is used for the axial adjustment of! the upper roll I and which is supported by a bracket 25 provided on the upper casing 9. As shown by Figs. 5 and 6, helical teeth are formed. on they periphery of the rotatable nuts for. the adjusting screws permitting the operationof said screws.
The above described, construction enables a hitherto unattainable quick change of housing to be made, which can be effected by the simple transposition of the supporting columns and the parts connected therewith, and moreover, a very small and light housing construction is obtained permitting a very small spacing of the rolls from one housing to the other, which is of especial advantage in the continuous rolling of wire. 25
While I have described my invention in detail, it is obvious that the construction shown on the drawing is capable of various modifications, and my invention, therefore, is not limited to the construction as shown and herein described.
I claim:
1. In combination with the cooperating rolls of a rolling mill and the roll housing, an individual electric motor for'drlving each roll, the roll being mounted direct on the outwardly projecting free end of the shaft of its motor and the motorcasings constituting essential parts of the, roll housing, the wound stators of said motors having no larger dimension in the direction toward each other than the radius of the rotors.
2. In combination with the cooperating rolls of a rolling mill and the roll housing, an individual electric motor for driving each roll, the roll being mounted direct on the projecting free end of the shaft of its motor and the motor cas- 45 ings constituting essential parts of the roll housing, four columns supporting said motor casings in superposed position, a cross-beam mounted on the top of said columns, means elastically suspending the upper motor ca-sing from said crossbeam, and adjusting screws provided in said cross-beam.
3. In combination with the cooperating rolls of a rolling mill and the roll housing, an individual electric motor for driving each roll, the roll being mounted direct on the projecting free end of the shaft of its motor and the motor casings constituting essential parts of the roll housing, four columns supporting said motor casings in superposed position, a cross-beam mounted on the top of said columns, means elastically suspending the upper motor casing from said cross-beam, and adjusting screws providedin said cross-beam, a base-plate at the bottom of the roll housing adapted to receive said columns, and collars formed on said columns for supporting the lower motor casing.
4. In combination with the cooperating rolls of a rolling mill and the roll housing, an individual electric motor for driving each roll, the roll being mounted direct on the projecting free end of the shaft of its motor and the motor casings constituting essential parts of the roll housing, and means for axially adjusting the motor shaft carrying one roll relative to the motor shaft carrying the cooperating roll.
5. In combination with the cooperating rolls of a rolling mill and the roll housing, an individual electric motor for driving each roll, the roll being mounted direct on the projecting free end of the shaft of its motor and the motor casings constituting essential parts of the roll housing, four columns supporting said motor casings in superposed position, a cross-beam mounted on the top of said columns, means elastically suspending the upper motor casing from said cross-beam and adjusting screws provided in said cross-beam, rotatable nuts on said adjusting screws having helical teeth formed in their periphery permitting the raising and lowering of the upper motor casing relative to the lower motor casing.
6. In combination with the cooperating rolls of a rolling mill and the roll housing, an individual electric motor for driving each roll, the roll being mounted direct on the projecting free end of the shaft of its motor and the motor casings constituting essential parts of the roll housing, four columns supporting said motor casings in superposed position, a cross-beam mounted on the top of said columns, means elastically suspending the upper motor casing from said crossbeam, and adjusting screws provided in said cross-beam, the upper motor casing being formed with a depending flange overlapping the upper edge of the lower motor casing.
7. In a rolling mill, superposed working rolls, superposed individual electric motors for driving said rolls, and casings enclosing said motors constituting a common housing, the ends of the motor-shafts projecting freely from one side of said housing supporting said rolls outside of said housing.
8. In a rolling mill, superposed working rolls, individual electric motors for driving said rolls, the casings of said motors forming a housing, the ends of the motor-shafts projecting freely from one side of said housing supporting said rolls outside of said housing, a base plate, a cap, and means for supporting said cap on said baseplate, said motor-casings being held by said supporting means in superposed position intermediate said base-plate and said cap.
9. In a rolling mill, superposed working rolls, individual electric motors for driving said rolls, and means including a common housing for said motors for supporting said motors in superposed position, the ends of the motor-shafts outwardly projecting from said housing having said rolls directly mounted thereon.
