Definitions
- the invention relates to a torque arm on the oil collecting box 2, 2 'in the area of the paired connection of the spindle head and the roll neck in rolling stands during their adjustment both in the vertical and in the axial direction, each with a fastening point on the upper and lower oil collecting box.
- the rolling stands in hot rolling mills are usually connected to a motor-gear unit via toothed spindles.
- the individual toothed joint spindle is connected to the roll neck on the spindle head, for example a work roll.
- Relatively heavy oil collection boxes are mounted on a roller bearing on the rotating spindle heads. Since the rollers in the roll stand assume variable positions, the adjustability of the spindle heads and thus the adjustability of the oil collecting box in the horizontal as well as in the vertical direction is required.
- toggle levers that can be connected with joints to be used for fastening the oil, as can be seen in the attached FIG. 1, for example.
- Such a toggle lever connection consists of two tubular elements which are connected to one another via an intermediate joint.
- Two end heads are welded to the opposite ends of the toggle levers. Fastening bolts are provided on the oil collecting cheeses, onto which the end heads are attached, held in an articulated handle and secured with a plate.
- Document DE 1 902 894 describes a toothed joint spindle for rolling mill drives with a device for circulating lubrication.
- the device has a grooved ring which serves for the oil supply, surrounds the spindle shaft in a sealed manner and is held non-rotatably relative to it, from which oil can be fed to the tooth joints through channels of the spindle shaft, with a spindle shaft which serves to drain the oil and has a non-rotatable housing surrounding it and with an oil pump which is connected on the suction side with the interposition of a cooling device to the housing and on the pressure side with the grooved ring.
- the ring body is mounted within the or one of the oil discharge housings on the spindle shaft and the tooth joint or teeth protrude at least partially into the oil discharge housing.
- Guide walls that protrude into the housing and are arranged on the spindle sleeve form a leak connection.
- the housings assigned to the roller-side spindle heads of the two toothed joint spindles can be moved on common guide rails both in the vertical direction and also displaceable relative to one another in the axial direction. These guide rails secure the housing against rotation with the toothed spindle.
- a one-piece torque arm is installed instead of the multi-part toggle lever described above.
- this consists of a one-piece strip with a rectangular cross section, in particular, made of flex-resistant material, which is connected to the upper oil collecting box in a pendulum manner at the upper end by a hinge in a vertical plane and in the region of its lower end in a form-fittingly compatible recess in a guide link. is both slidable and slidably guided in the vertical pendulum plane with a variable inclination angle ⁇ .
- This torque arm is structurally simple and represents a problem-free, easy to install and elastic connection.
- An embodiment of the torque arm provides that the guide link is assembled with a pair of plane-parallel broad side walls and narrow side walls, forming a rectangular guide recess.
- a further advantageous embodiment provides that the broad side walls are arranged at a mutual distance from one another in such a way that they form a sliding fit for the bar.
- the narrow side walls, which are aligned with the inner guide link, are preferably of a convex shape, so that the bar remains movable in an oscillating manner.
- the rectangular bar consists of a glass fiber reinforced plastic such as hard tissue or glass hard tissue for oil-free operation.
- Figure 1 in a view and in a partial section of an embodiment of the torque arm according to the prior art with articulated split knee lever in articulated connection with the upper and with the lower oil collection box.
- Figure 2 The arrangement of the torque arm according to the invention on oil collection box for their adjustment in the vertical and axial directions.
- FIG. 3 The torque arm according to FIG. 1 in a view (FIG. 3a) and in a side view; partly in section (Fig. 3b)
- the design of the torque arm according to the prior art according to FIG. 1 shows, in section and in view, the spindle heads of the toothed joint spindles within the oil collection box 2, 2 'surrounding them.
- the toggle lever shown in Figure 1 consists of two tubular elements 11, 1 1 ', which are connected at one end via a joint 12. At the opposite ends of the tubular elements 11, 11 ', two end heads 10, 10' are attached, for example welded. Fastening bolts 13, 13 'are provided on the oil collecting box, onto which the end heads 10, 10 ' are attached and secured with a plate 14, 14 ' .
- FIGS. 2 and 3 The design of the torque arm according to the invention is in detail in FIGS. 2 and 3, namely once in a perspective view (FIG. 2) and on the other hand (FIG. 3) once in a view (FIG. 3a) and once in a side view (Fig. 3b) shown.
- the simplest version of the new torque arm consists of a rectangular bar 3, which is preferably made of a glass fiber reinforced plastic such as hard glass fabric or hard fabric can be made.
- a joint 4 For fastening the support to the upper fastening point 10 there is a joint 4 with a hinge pin in a compatible bore.
- the guide link 6 is assembled with a pair of plane-parallel broad side walls 7, 7 'and narrow side walls 8, 8' to form the rectangular guide recess 5.
- the side walls of the joint 4 are identified by 4 '
- the broad side walls are identified by 7, .7' and the narrow side walls by 8, 8 ', forming the rectangular guide recess 5.
- the broad side walls 7, 7 ' are arranged at a mutual distance such that they form a sliding fit for the bar 3. As a result, they can slide easily without using lubricants, the distance-variable movements of the work rolls or the articulated spindles and additionally the angle ⁇ shown in FIG. 2 of the shift position of the work rolls.
- the inner sides of the narrow side walls are convex.
