Definitions
- the invention relates to a rolling device with a shaft, a rolling ring arranged on the shaft and an arrangement for securing a constant operating position of the rolling ring on the shaft.
- a threaded nut is also used for tensioning the rolling ring.
- a hydraulic tensioning device is used to generate a hydraulic prestressing force, which has to be installed separately and comprises a tensioning sleeve surrounding the rolling ring.
- This arrangement has the disadvantage that the hydraulic tensioning device is complex and cumbersome to use.
- the clamping sleeve covers the outside of the rolling ring and therefore an optical control of the rolling ring is not possible during the clamping process.
- it can only be used with overhung roller ring assemblies.
- there are also the problems caused by the use of a threaded nut as a ring stop namely the fact that the load-bearing number of thread turns is limited.
- the width of the compensation ring must be less than the width of the gap, because otherwise the compensation ring would not be mountable; moreover, compensation rings cannot be used continuously different axial dimensions are kept in stock. Therefore, the achievable axial operating clamping force is always considerably lower than in the case of devices which allow the clamping state achieved by the hydraulic clamping force to be infinitely fixed.
- the invention relates to the known type of rolling device in which the securing of a constant operating position of the rolling ring on the shaft takes place essentially by an axial operating clamping force and in which the arrangement essentially comprises: two retaining rings axially fixed to the shaft on both sides of the rolling ring ; a hydraulic power clamping device for transferring the rolling device from the unclamped state into a preliminary clamping position in which the rolling ring is supported on the end face on one of the two retaining rings; a receiving space for a compensating ring between the other of the two retaining rings and the rolling ring; a compensation ring in the receiving space, which can be brought into the operating position in the provisional clamping position of the arrangement, in which its axial dimension is greater than the axial dimension of the receiving space in the untensioned state, such that the operating clamping force between the two after releasing the hydraulic force clamping device Retaining rings is transferred via the roller ring and the compensation ring in the operating position.
- the object on which the invention is based is to improve this rolling device with regard to the space requirement, the manufacturing and operating effort and the clamping security.
- the solution according to the invention is that the compensating ring and a ring adjacent to it cooperate on their end faces with sawtooth-shaped, distributed over the circumference, complementary inclined surfaces with a slope that is far below the self-locking limit compared to the circumferential direction.
- a rolling ring arrangement which comprises two rolling rings for the rolling of H-shaped steel profiles, the spacing of which is adjustable from one another.
- They On the mutually facing end faces, they have sawtooth-shaped inclined surfaces distributed over the circumference, which interact with complementary inclined surfaces of an adjusting ring arranged between them.
- This can be rotated by means of a hydraulic motor contained in the arrangement, as a result of which the roller rings are either pushed apart axially or are given the possibility of mutual approximation under the influence of a further hydraulic drive.
- the slope of the inclined surfaces is relatively large and presumably not below the self-locking limit. This is possible because they are not intended to maintain the operating position of the roller rings.
- conical sleeves are provided between the clamping rings and the shaft, which are tensioned by a spring to ensure the operational connection between the shaft and the rolling rings, and can be released by a hydraulic drive if the rolling rings are to be adjusted relative to one another.
- This document does not contain the teaching that the operating clamping force for rolling rings can be generated under the very special design requirements of the invention by a ring with inclined faces at the end.
- the one retaining ring which can be formed by a threaded nut on a shaft thread, is first set against the rolling ring as far as possible and without play, the complementary sawtooth surfaces of the retaining ring and the compensation ring are in deepest engagement.
- the roll ring arrangement is then put under tension by the hydraulic power tensioning device. This loosens the mutual contact of the rings and creates axial play. Now the compensation ring is rotated relative to the retaining ring until the axial play has disappeared. Then the hydraulic tension can be released.
- the arrangement is extremely simple because the hydraulic power clamping device can be contained on or in the one retaining ring, expediently radially inside the compensating ring, so that it is easily accessible from the outside and without the need for a surrounding force-transmitting sleeve. Since the power clamping device is integrated in the adjustable retaining ring, the axial space requirement is small. In contrast to a nut, which must be relatively large for a given load, the compensating ring can transmit high axial forces even with small dimensions, because the entire contact surface of the complementary inclined surfaces can be regarded as load-bearing.
- the shaft-fixed designed as a nut retaining ring with a view to the power transmission via the thread on the shaft must have a considerable cross-sectional dimension, not only the hydraulic power clamping device, but also the compensating rings can be accommodated in their cross-section, which further reduces the space requirement and the arrangement is simplified.
- the force clamping device and the compensating ring can then act parallel to one another on one and the same ring adjacent to the retaining ring, preferably even on the same end face of this ring.
- the device according to the invention allows the transmission of unusually large axial forces, it is particularly suitable for arrangements in which the rolling ring or the Roll rings are predominantly or even axially clamped.
- the application of the invention can be used both in the case of roll stands mounted on both sides of the roll ring and in the case of overhung use.
- the invention is also applicable not only to rolling devices, but simply when in a clamping arrangement consisting of a bolt, an abutment connected to the bolt and a retaining ring, any parts located between the abutment and the retaining ring, preferably surrounding the bolt in an axial manner Direction must be set under compressive stress, whereby the bolt is stretched.
- the shaft 1 forms or carries a shaft-fixed collar 2 which, as a retaining ring on one side of the rolling ring, forms an abutment for the rolling ring tension and can be formed in one piece with the shaft, but need not be.
- the roller rings 3 are mounted on the shaft 1 with intermediate rings 4 and centered either directly on the shaft circumference or by further means, not shown.
- the shaft is provided with a thread 5 on which a nut 6 sits, which forms the other retaining ring.
- a thread 5 on which a nut 6 sits, which forms the other retaining ring.
- roller rings 3 are clamped axially between the retaining rings 2 and 6.
- the nut 6 contains an annular piston 7, which can be acted upon via lines 8 with hydraulic medium.
- the nut 6 contains on the outside and on its end facing the rolling ring arrangement 3, 4 a recess 9, which forms the receiving space for the compensating ring 10.
- Both the hydraulic power tensioning device 7 and the compensating ring are thus accommodated in a space-saving manner in the longitudinal sectional area of the nut 6.
- the shape of the elements involved, in particular also of the adjacent intermediate ring 4, on which the force clamping device and the compensating ring act, is very simple.
- the cooperating end faces 11 of the nut 6 and the compensating ring 10 are, as can be seen in the lower half of the figure, sawtooth-shaped with a very low slope.
- the slope of the flank must be very low, i.e. are very far below the self-locking limit, so that the clamping arrangement cannot be loosened by rotating forces acting on the rolling ring. In extreme cases, it may be appropriate to choose the direction of the slope so that the axial tension is increased when the compensating ring 10 is rotated relative to the ring 6 by the drive torque.
- the compensating ring is first rotated as far as possible so that the sawtooth surfaces 11 are in deepest engagement and the common axial length of the compensating ring 10 and the retaining ring 6 is minimal. Then the nut 6 is screwed on as tightly as possible, so that only a slight axial compression of the rolling ring arrangement 3, 4 is to be expected when the force clamping device is activated. If the annular piston 7 is then acted upon by hydraulic fluid, the rolling ring arrangement 3, 4 is pressed further together and the shaft is stretched. This loosens the arrangement and creates axial play.
- the compensation ring 10 is rotated so that the Clearance is eliminated, whereby the tension state of the rolling ring arrangement remains fixed and the operating tension force is maintained even after the power tensioning device is released.
- the proportion of the area in which the sawtooth flanks 11 of the compensating ring 10 and the nut 6 interact is reduced; however, these can easily be dimensioned so that they are still sufficient even after adjusting the compensating ring.
- the design of these flanks of any size allows the transmission of any large axial forces evenly over the circumference. It goes without saying that the sawtooth surfaces 11 could also be provided between the compensating ring 10 and the intermediate ring 4 instead of between the compensating ring 10 and the retaining ring 6.
