Abstract: A rolling stand includes at least one roller having a roller journal which is rotatably supported by an eccentric bushing which in turn is rotatably supported by a low-friction bearing unit. An adjusting mechanism exerts an adjusting force on the eccentric bushing for rotating the eccentric bushing with respect to the housing and maintaining the eccentric bushing in a desired position. In order to determine a rolling force in the rolling stand, the eccentric bushing is rotated to a desired position relative to the housing by the adjusting mechanism, and an effective adjusting force in the adjusting mechanism is measured when the eccentric bushing is held in the desired position. The rolling force can then be ascertained on the basis of the measured adjusting force.

Abstract: A roll stand for rolling bar-shaped or tubular stock, having a stand housing, having at least one roll which is arranged on a roll shaft rotatably mounted in the stand housing and is connected in a rotationally fixed manner to the roll shaft via a frictional connection, in which roll stand the roll is held in its axial position on the roll shaft in a positive-locking manner by sleeve elements adjoining axially with respect to the roll shaft.

Abstract: The invention relates to a roll stand for rolling bar-shaped or tubular material, in which a plurality of rolls 2 form a roll pass. The rolls 2 are each mounted on a roll shaft 8 split in two, the roll shafts being mounted in the stand housing 1 of the roll stand in such a way that they can be shifted radially for the purpose of adjusting the rolls 2 relative to the roll axis 3. In order to be able to permit a simple displacement of the sectional shafts 9, 10 of the roll shafts 8, an axial bearing which axially fixes the roll shaft 8 is either provided on a hub, relative to which the roll shaft 8 can be selectively shifted or fixed in the axial direction, and/or that part of the axial bearing which is connected to the stand housing is arranged in such a way that it can be released from outside.

Abstract: A rolling unit for a rolling mill for rolling or sizing metal pipes, bars or wires has at least three rolls arranged in a star arrangement. Each roll has a separate drive mechanism and is rotatably mounted on bearings on both sides of it. The rolls are adjustable radially together with the bearings. The improved rolling unit has smaller outside dimensions but can take a higher load. The number of individual rolling unit parts is also reduced as well as manufacturing and assembly expenses. For this purpose the bearings of the roll shafts are mounted in respective eccentric sleeves, whose rotational position may be adjusted manually and in a stepwise manner between several rotational positions.

Abstract: A rolling unit for a rolling mill for rolling or sizing metal pipes, bars or wires has at least three rolls arranged in a star arrangement. Each roll has a separate drive mechanism and bearings on both sides of the roll. The rolls are adjustable radially with the bearings. A higher load can be borne with smaller outer dimensions. Furthermore the number of individual parts of the rolling unit is reduced as well as manufacturing and assembly expenses for the rolling unit. For this purpose the bearings of the roll shafts are mounted in respective eccentric sleeves, whose rotational position is continuously changed by means of an adjusting device. A securing device is provided however to fix the rolls in one rotational position.

Abstract: A rolling mill for rolling or sizing of metallic pipes, bars and wires has a plurality of rolling units which are arranged on a straight line close to one another and can be exchanged jointly, only a few, or individually, each of the rolling units having at least three rollers which are arranged in a star-like configuration around a rolling axis, drive shafts and motors each driving a respective one of the rollers in all the rolling units, a rolling unit housing provided for the rolling units, roller bearings provided for the rollings, and multi-part rolling shafts provided for supporting the rollers so that the rollers can be exchanged without dismounting of the rolling unit housing and the roller bearings.

Abstract: A roller guide for a roll stand for precise guiding of a rod-shaped or wire-shaped rolling product in a caliber opening formed by rolls which engage the rolling product from an outer side and are distributed on its periphery, the roller guide has angular levers provided with legs on which the rollers are rotatably supported, turning pins on which the angular levers are turnable and which have turning axes extending transversely to a roll axis, an adjusting bushing by which the levers are jointly turnable so as to jointly displace the rollers radially to the roll axis, a coupling rod arranged between the adjusting bushing and each of the levers, the coupling rod being hingedly engaged on a leg of the lever which faces away from the rollers, and an angle between an engaging point between the coupling rod on the lever and a rotary axis of the roller with an apex point on the turning axis of the turning pin amounting to between 80 and 92.degree..

Abstract: A three-dimensional single-wheel suspension for wheels of a railed vehicle, where a wheel unit, including a wheel, a wheel mounting, a non-rotating wheel carrier, and a drive and/or braking mechanism, is provided to execute steering and/or cushioning movements relative to the vehicle. The wheel carrier is movably connected to the vehicle via linkage rods, and is also connected to the wheel carrier of the oppositiely disposed wheel. The point of connection of at least one of the linkage rods to the vehicle is adjustable as a function of such vehicle states including forward or rearward travel, straight-ahead travel or travel through a curve, and braking or driving, and/or including a function of the state of wear of the wheel.
