Cl. F16h1/06, 57/00 US. Cl. 74-410 3 Claims ABSTRACT OF THE DISCLOSURE A device for the actuation of a mangle wheel by a pinion. The latter is disposed in a housing which is supported at a fixed point and is guided by a plurality of trains which selectively can engage the guiding elements of the housing from the outside, the inside or from both the outside and inside.

The invention relates to a device for the actuation of a mangle or ring gear by a pinion disposed in a pinion housing which is supported at a fixed point and guided by appropriate elements on tracks concentrical with the mangle wheel. 1

In known devices for the transmission of motion of a ring gear or mangle wheel of large diameter or of a tilting gear for a steel mill converter, thepinion housing is supported by smooth tracks, concentrical to the gear axis, by means of rollers disposed on the-housing A known device for the balancing of changes in meshing of gear drives also used smooth tracks with a mangle wheel. Therein, one of the bars carrying: the drive elements serves as guideway. However, it usually is necessary to provide roller supports for the pinion housing on the side facing away from the pinion to, counteract the tendency of the pinion to jump out of the ring gear. This requires additional guideways which frequently are difficult to place, for instance when the ring gear isdisposed on a drum.

It is the object of the invention to provide for mangle wheels guideways or trains which selectively can engage the guide elements of the pinion housing from the inside or the outside, or from both the inside and outside.

The device according to the inventon provides a drive for a mangle wheel by a pinion mounted in a pinion housing. The latter is supported at a fixed point and is guided by suitable directional elements along tracks which are concentric with the wheel. The free ends of the meshing pin teeth form the tracks. The pinion housing may be a cradle or sliding carriage. Such a construction wherein friction occurs between the housing and the ends of the pin teeth can be chosen when the guidance of the pinion housing is in effect only intermittently, i.e., when the position of the pinion axis relative to the axis of the ring gear has been fixed by other means.

In a preferred embodiment of the invention, the ends of the pin teeth carry rollers which form roller trains, and the directing elements are guides which are fastened to the pinion housing in an articulated manner.

The number and disposition of the guides depends upon the general provisions; they may engage the roller train on the side facing away from the pinion or else may be provided on both sides of the roller train.

Good direction of the pinion housing can be effected when per roller train, i.e., on both sides of the ring gear, on the track facing away from the pinion, two guides are provided and one guide is disposed on the track facing the pinion.

The invention now will be more fully explained with reference to the accompanying drawings.

In the drawings:

FIG. 1 is a plan view, partly in section, that schematically shows a ring gear on which a pinion housing, provided with guides, is supported;

FIG. 2 is a side elevational view thereof; and

FIG. 3 is a plan vview similar to FIG. 1, showing a modified embodiment'having three pairs of guides.

Referring now to these drawings, a driving pinion 1 is installed in pinion housing 2. The latter has guides 3 fastened to it in an articulated manner. Guides 3 are'disposed swingably about bolts 4. Pinion housing 2 is connected to a fixed point by a support 5.

The gear teeth of pinion 1 engage in pin teeth 6 of a mangle wheel of large diameter. The free ends of the pin teeth 6 carry rollers 7 that form a guideway, such as two roller trains, namely one train facing away from, and one facing, the pinion 1. FIG. 2 shows the bars 11, supporting the teeth 6.

Pinion 1 is actuated by shaft 10 by way of a reduction gearing composed of

gears

8 and 9.

In the embodiment according to FIG. 3, the roller train on the side facing away from pinion 1 is assigned two guides 3 and that facing pinion 1 one guide 3a. The latter is disposed swingably about bolt 4a. This provides an exactly defined engagement of pinion 1 in the meshing teeth or leaves.

It is a considerable advantage of the invention that a concentric guideway is provided by the mangle wheel and the use of the pin teeth 6 carrying extensions in the form of rollers 7. Upon suitable disposition and formation of the guides, the construction according to the invention is applicable to ring gears which are out of round because the roller train forcedly follows each curvature in the graduated circle. Thus, the invention facilitates the manufacture of drives for ring gears of large diameter by simple means with the aid of the mangle wheel.

We claim as our invention:

1. A device for the actuation of a mangle wheel having pin teeth which comprises a pinion engaging the teeth of said mangle wheel; a housing for said pinion in which said pinion is journall'ed; said housing being pivotably supported at a fixed point; guide elements mounted with relation to said housing; and extensions formed on said pin teeth and constituting a guideway, said guide elements engaging said guideway for positioning said housing rela-. tive to said pin teeth.

2. The device as defined in claim 1, wherein said extensions are provided with rollers forming trains; and said guide elements are guides disposed on said housing in an articulated manner.

3. The device as defined in claim 2, wherein, on the roller train facing away from the pinion, two articulated guides are assigned and, on the roller train facing the pinion, one articulated guide.
