Definitions

  • the invention relates to a rolling ring assembly according to the preamble of claim 1 and a method for tensioning a rolling ring on a shaft in such a rolling ring assembly.
  • the necessary for a clamping operation, high axial operating voltage can alternatively be applied by the nut screwed onto the threaded portion or by the hydraulically operating, axial clamping device. Both work independently of each other.
  • the nut can be rotated or actuated independently of the axial clamping device, the axial clamping device operates independently of the mother.
  • the axial clamping device is intended to perform the clamping operation and the release operation.
  • the nut is designed to maintain the working tension achieved hydraulically.
  • the radial positioning is independent of the axial clamping.
  • the rolling ring can be centered by means of the radial positioning unit without the axial tension having to be changed or changed.
  • the rolling ring assembly thus enables an axial tensioning device formed in a tightening tool to be sequentially used for a plurality of rolling ring assemblies during tensioning and relaxing.
  • the achieved axial tension is maintained by the nut, which is a relatively simple mechanical component. It must therefore not be provided an expensive hydraulic working axial clamping tool for each rolling ring assembly.
  • the radial positioning unit operates independently of the two components responsible for the axial tension, namely the nut and the hydraulically operating axial clamping device, the radial positioning can be carried out selectively and carefully.
  • the force exerted on the rolling rings radial force can be dosed very accurately and targeted.
  • An excessive radial stress, which would reduce the life of the rolling rings, can be prevented. Rather, the radial stress can be kept so low that only a positioning takes place without the rolling ring is noticeably stretched radially. It is therefore deliberately spoken of a radial positioning and axial clamping in the context of the present application.
  • the invention also relates to a method for tensioning a rolling ring on a shaft of a roll stand using the rolling ring arrangement, as described above. It is the object of the invention to provide a method for tensioning a rolling ring of a shaft, in which as little as possible controllable radial forces are exerted on the rolling ring during clamping and independently of this a high axial tension necessary for the transmission of a torque during the rolling process can be applied.
  • the mother as well as the axial clamping device is able to exert an exclusively axial clamping force on the rolling ring, after the successful clamping, which must be done hydraulically, and tightening the nut against the rolling ring, the hydraulic voltage can be switched off and the clamping device can be removed. The axial tension is then maintained by the nut. Completely independent of this, the radial positioning takes place by means of the radial positioning unit. The latter is only operated so that the radial stresses on the rolling ring remain within the permitted limits, but sufficient radial positioning or centering of the rolling ring is achieved.
  • the radial positioning unit after reaching the high axial operating voltage, the radial positioning unit is released, for example, relaxed.
  • the radial positioning of the rolling ring when once the high axial operating voltage is applied, no longer change, because the rolling ring is fixed by the high axial working voltage.
  • the radial positioning unit operates hydraulically and has an expandable hydraulic pressure chamber system which does not communicate with the hydraulically operating axial tensioning device.
  • the radial positioning has its own drive, which is preferably designed hydraulically. It is basically possible to form this drive also otherwise, so for example mechanical, pneumatic or the like.
  • the centering means have a ring cone.
  • a rigid centering has proved to be favorable.
  • a combination of a centering cone and an axially acting, hydraulic pressure chamber system has proven.
  • a clamping tool which receives at least the axial clamping device, but preferably also accommodates an axially operating hydraulic pressure chamber system of the radial positioning unit.
  • the nut with bores running parallel to the axial direction and insert a pin into each bore, which pin is displaceably arranged in the bore and designed for pressure transmission between the hydraulic pressure chamber system of the radial positioning unit and a ring cone .
  • the slopes of the ring cone are preferably chosen so that it is self-locking.
  • a radially expandable sleeve As a centering a radially expandable sleeve is advantageous. This can, as has already been pointed out, work hydraulically; it can also work otherwise, for example by axial force acting on the sleeve, expanding radially. Such a sleeve can be used in place of the ring cone mentioned above.
  • the attachment area has a smaller outer diameter than the inner diameter of the thread of the nut. It is then possible, when attaching or removing the nut, to rotate it only over the threaded area, while the nut can be pushed over the mounting area. This simplifies assembly.
  • the threaded area can be designed as a fine thread.
  • the attachment region can be designed so that rapid assembly and disassembly of the clamping tool is possible, it can be designed, for example, as a bayonet connection, as Schnellschraubtagen etc ..
  • the hydraulically operating, axial clamping device comprises a support means, the nut radially and axially overlaps and has the window for a rotation of the nut, preferably, the support means is designed as a support sleeve or a plurality of support pins.
  • the two axial clamping means namely the nut and the axial clamping device, are arranged axially next to one another. They both act on the same side surface of the rolling ring, albeit on different faces of the side surface of the rolling ring, or an intermediate support ring or the like.
  • the support means transmits radially outside the nut, the clamping force of the axial clamping device on the rolling ring.
  • the support means may be of any desired design, for example a ring with windows, an arrangement of pins, etc. Through the windows, rotation of the nut is possible without the support means having to be actuated.
  • the nut has a threaded portion adapted to the female thread and is located between the nut thread and rolling ring an axial clearance.
  • This axial clearance is preferably greater than the diameter of the threaded portion.
  • the axial clearance acts at least as part of an axial spring. It is stretched by the axial clamping device. The axial spring pulls the nut against the rolling ring after tensioning.
  • the clamping tool can be used for other rolling ring arrangements.
  • the invention preferably relates to shafts with free shaft end.
  • Figure 1 shows a first embodiment of the rolling ring assembly, in this embodiment, the individual features and functions are explained.
  • the other three embodiments according to Figures 2, 3 and 4 including 5 will be explained with reference to the statements to the first embodiment only to the extent necessary for the description of the changes or deviations.
  • functionally identical, in particular identical components carry the same reference numerals.
  • the invention preferably relates to end-mounted rolling ring arrangements, but in principle can also be applied to two-sided rolling ring arrangements.
  • the rolling ring assembly according to the first embodiment has a rolling ring 22 made of hard metal, which has 2 grooves in the embodiment shown here. He is for the production of long material, z. As wire, designed.
  • the arrangement further has a shaft 20, of which only one (left) end region is shown.
  • the shaft 20 has a collar on which the rolling ring 22 is supported to the right. Interposed is a sealing arrangement 24, it is known ansich, they need not be discussed in detail here.
  • the shaft 20 Starting from its shaft collar and towards the left, free end, the shaft 20 initially has a receiving region 26 for the rolling ring, a free region 28, a threaded region 30 and a fastening region 32.
  • the rolling ring is located radially outside the receiving region 26, which is here is made substantially cylindrical.
  • a centering means 34 is arranged, which is designed here as an oil retaining pocket. The centering means 34 may be controlled and radially expanded depending on other actuators to be described.
  • the free area 28 serves as a spring together with optionally other portions of the shaft 20, this will be discussed later.
  • the threaded portion 30 is designed as a fine thread, with him a thread of a nut 36 is engaged. This has the shape of a pot in the embodiments, but this form is not mandatory. It is crucial that the nut 36 including the threaded portion 30 is designed so that it can exert on the left side surface of the rolling ring 22 a high axial working tension, which is sufficiently large for a transmission of a torque required for a rolling torque between shaft 20 and rolling ring 22nd It is possible to provide on the side surface 38 an intermediate ring, support ring or the like, so that the right end face of the nut 36 does not bear directly on the rolling ring 22.
  • the nut 36 finally has puncture openings 40 on its outer shell. They are distributed so that the nut 36 can be rotated comfortably. Other means of attack for a turning tool z. B. polygonal, toothing or a mechanical rotating device for the nut 36, for example by means of a driven toothed belt, are possible.
  • the attachment region 32 is provided for a clamping tool 42, which has a holding region 44 cooperating with the attachment region 32.
  • threaded portion 30 and mounting portion 32 throughout in one embodiment, for example, as a thread.
  • threaded area 30 concretely to the requirements of the nut 36, in particular as a fine thread, and to design the fastening area in such a way that the clamping tool 42 can be quickly pushed onto the mounting area 32 or otherwise mounted thereon.
  • a mounting area 32 and holding portion 44 for example Aufsteckgewinde, bayonet, coarse thread and the like.
  • the outer diameter of the mounting portion 32 is smaller than the inner diameter of the nut 36.
  • a support means 46 Radially outside the nut 36 is a support means 46 which has substantially the shape of an annular sleeve.
  • the support means 46 has windows 48, which are located in the region of the insertion openings 40.
  • the support means 46 is arranged between the clamping tool 42 and the rolling ring 22. It abuts another partial surface of the side surface 38 on the rolling ring 22 as the right end surface of the nut 36. Via the support means 46, an axial stress is applied to the rolling ring 22.
  • a hydraulically operating, axial clamping device In the clamping tool, a hydraulically operating, axial clamping device is provided. It has a hydraulic working space 52.
  • the holding area 44 is provided on a stationary part 54. Opposite this is a cylinder 56 in the axial direction 58 hydraulically movable.
  • the support means 46 abuts against the right end surface of the cylinder 56. If the working space 52 filled with hydraulic fluid, the cylinder 56 presses the support means 46 against the rolling ring 22, so that it is axially tensioned.
  • axial tensioning of the rolling ring 22 can take place either through the nut 36 and / or through the axial tensioning device 50.
  • the axial clamping device 50 of the clamping tool 42 is used only for clamping and loosening. The tensioned state is maintained by the nut 36, as Figure 5 shows.
  • a radial positioning unit 60 is provided, of which a section, namely the centering means 34, has already been mentioned.
  • the radial positioning unit 60 consists of a centering means and an actuating means which actively performs the controlled radial expansion or movement of the centering means.
  • This actuating means also called drive, is designed hydraulically in the embodiment of Figure 1.
  • an oil hole is made, which consists of an axial bore and a radial bore that hits them.
  • the radial bore opens into an expandable hydraulic pressure chamber system 64 of the radial positioning unit 60, this pressure chamber system 64 is provided in the embodiment of Figure 1 in the centering means 34.
  • This has an outer annular disc, which expands upon filling of the pressure chamber system 64 with hydraulic fluid to the outside and therefore can form a radial force on the rolling ring 22.
  • This force is preferably used only for radial centering or positioning, but not for radial clamping.
  • a tightening process is as follows: First, the parts as shown in Figure 1, mounted.
  • the rolling ring 22 is neither radially centered nor axially tensioned.
  • the radial positioning unit 60 By means of the radial positioning unit 60, a certain positioning is carried out, namely the centering means 34 is acted upon hydraulically with a first positioning force. As a result, a game between Walring 20 and shaft 20 is eliminated in the radial direction, at least reduced.
  • the axial clamping device 50 of the clamping tool 42 is now actuated, the piston 56 is axially advanced to the right. This is done an axial tensioning with a first axial tension. This is still below the later required, high axial working voltage.
  • the axial tensioning device 50 is actuated again, now with a second axial tension, which is higher than the first axial tension.
  • the nut 36 is then again rotated so far against the rolling ring 22 that it rests against this. She has thereby obtained the opportunity to take over the axial stress. It can now be relaxed, the axial clamping device 50, so the piston are moved back. This can be done for example by positive emptying, for example, suction, the hydraulic fluid from the working chamber 52. Now it is the mother 36 who the high axial working tension on the rolling ring 22 exerts. The clamping tool 42 and the support means 46 can be removed. The pressure in the pressure chamber system 64 is maintained because a check valve is provided in the oil hole 62. It can be released by a pin.
  • a protective cap 66 is attached to the free shaft end, as shown in FIG. 5.
  • Fig. 5 refers to another centering means, which should be clearly stated here.
  • the protective cap bears against the side face 38 of the rolling ring 22 with a seal. It seals the entire end region beyond the rolling ring 22.
  • a suitable locking device for example a lock nut.
  • the rolling ring assembly in the condition shown in Fig. 5 can now be used for practical rolling operations. If the rolling ring 22 worn, or you want to dismantle for other reasons, the clamping tool 42 is again recognized. An axial tension is exerted on the roller ring 22 by means of the axial tensioning device 50 and transmitted by the support means 46, which is so great that it is possible to rotate the nut 36 freely. In addition, the radial positioning unit 60 is relaxed, if not already done. The clamping tool 42 can now be removed. Also, the mother can be removed. The rolling ring 22 can be removed.
  • the centering means 34 is a ring cone to which a further inner annular cone 68 is associated in opposite directions.
  • the actuating means of the radial positioning unit 60 is now provided in the clamping tool 42.
  • the pressure chamber system 64 is provided in the stationary part 64, to him an annular piston 70.
  • the nut 36 has a number of axially parallel bores 72, which are formed for example as passages and preferably evenly distributed on a cylinder. In each passage 72, a pin 74 is housed, which is freely displaceable in the axial direction.
  • the preferably identical pins 74 serve to transmit an axial positioning force from the annular piston 70 on the left side surface of the centering means designed as a ring cone 34th This left side surface lies in a radial plane, so has no gradations or the like.
  • the angles of the two annular cone parts 34, 68 are in the range of self-locking. This makes it possible not to maintain a once achieved radial positioning during the normal rolling operation to have to. It is quite conceivable and advantageous to fix the centering means 34 in the achieved positioning position, for example mechanically. This can be done for example on specially designed pins 74, for example, the passages 72 are designed as threaded holes and the pins 74 are replaced by threaded pins. Other mechanical fixations are possible.
  • FIG. 2 has the advantage that both the axial clamping device 50 and the actuating means of the radial positioning unit 60 are formed in a clamping tool 42. Furthermore, there are only solid body between rolling ring 22 and shaft 20.
  • the embodiment according to FIG. 3 differs from the exemplary embodiment according to FIG. 2 in that the centering means is now a radially expandable sleeve, which can be radially expanded via axially introduced forces. There are again provided pins 74, as they can be found in the embodiment of FIG. 2.
  • the support means 46 now has a spy window 76 or more thereof. These windows are recesses on the right side surface of the support means 46 so that there is no continuous investment here. Through the at least one spy window 76, it is possible to recognize that the nut 36 actually rests against the rolling ring 22.
