Description

The invention relates to a high-speed stranding machine with one of the interconnected Tubing sections assembled stranding rotor, the two adjacent ends of the tube sections are stored by a common outer roller bearing within a bearing stand.

The so far almost exclusively in use storage of the composed of pipe sections Verseilrotors of the high-speed stranding machine on support rollers has in terms of speed reached its limit. This is due on the one hand to the performance limit of the currently available Conveyor roller materials and, on the other hand, by the increasingly narrowing with increasing speed Tolerances of the parts influencing the smoothness. The special working procedures required complicate economic production.

The high speeds required in practice, which are not yet fully mastered in terms of vibrations cause the slip between the running surfaces of the rotor and idler roller to increase sharply, which can be masked by increased frictional wear, especially on the rollers. Which is on Abrasion accumulating on the running surfaces impairs the smoothness on the one hand, and generates it on the other hand he local pressure load peaks that lead to increased Wear and even lead to failure, mainly due to local overheating. Manufacturing inaccuracies of the planted areas cause different deviations in the rigidly flanged Verscil pipe the RotoracliM .-- from the straight line, which at Aligning the rotor must be canceled. The tensions thus generated are made elastic by the rotor added and lead to further additional loads on the rollers and restless Run. Hs can even go so far that the one gained through dynamic straightening of the individual rotors Advantage is diminished again. In addition, a stranding rotor with several bearing parts is considered static To consider an indefinite system, which enables the precise calculation and correct design of the storage is made more difficult.

High-speed stranding machines, in which the individual sections of the rotor are connected to one another by elastically deformable parts, have the disadvantage that with a long, multiply assembled rotor the angle at which the first rotor member rotates relative to the last rotor member becomes too large; In addition, rotor sections connected to one another in this way require two bearings, one in each of the two adjacent sections of the rotor.

The aim of the invention is to ensure that each pipe section which is supported by roller bearings. Is mounted in a vibration-damping manner. With the bewinkelbartp. elastic coupling should also be achieved that each pipe section independently is used in relation to storage, in relation to alignment errors and in relation to rotary mine of the stranding machine.

This object is achieved by the features characterized in claim I.

Advantageous further developments of the invention are described in the subclaims.

A known high-speed stranding machine (Belgian patent 525 393) has with the high-speed stranding machine according to the invention in common that the rotor sections at the ends of the stranding machine in Ball bearings are stored. There are, however, essential differences between the one according to the invention Objective of the Belgian patent can not be achieved. The Belgian patent does not use any Rotor tube in the traditional sense, but individually mounted and individually driven rings, rods and disks (collectively referred to as Verseilflügcl). The Belgian patent also shows no connection between the twisting wings, neither elastic nor inelastic. The Belgian patent specification in particular shows no elastic support of the stranding wings against the foundation. the The central twisting wings are stored in three rolls distributed around the circumference, and finally with the Belgian patent, the coil carriers overhung. The machine according to the Belgian patent specification is hardly comparable with the subject of the present application, it certainly takes the In no way anticipate the idea of the invention and its specific embodiments.

The same applies to another known high-speed stranding machine (French patent 1 483 097). This has in common with the high-speed stranding machine according to the present invention that the Rotorrohrc consist of steel tubes and are mounted in ball bearings, as well as that the coil carrier are mounted on both sides in the rotor tube. However, there are the main differences that the rotor tubes in the French patent rigidly with each other are connected; neither ball bearings nor the machine are elastically supported. The drive and Brake motors are partly part of the Roto-

ren; because the anchor of this MotorcVi is at the same time the rotor of the stranding machine. The features of the present invention are those of the French patent not to be found, and it can be seen in the French patent in particular with the present Invention intended 'effects do not achieve.

The invention is explained in more detail with reference to the drawing, for example, which shows an atxal section of the rotor shows areas of the adjacent ends of two pipe sections.

The pipe section 1 of the rotor, welded to the flange ring 2, is screwed to the bearing ring 3. Both are centered by the flange of the centering bush 4, which is screwed to the bearing ring 3. On the opposite plane surface of the centering bushing 4, the shim 5 is screwed to the clamping ring 6 and centered. Means oes clamping ring 7, the shim 5 is bolted at its large diameter to the flange 8 of the tubular portion 9 of the rotor. The inner ring 12 is fixed by the two sealing rings 10 and 11 screwed to the bearing ring 3. The two flange covers 13 and 14 hold the outer ring 15 of the roller bearing. This outer ring 15 is located in the inner housing ring 16, which is enclosed by the outer housing ring 17. Both rings 16 and 17 are connected by vulcanization with the intermediate layers 18 made of rubber or rubber substitutes. The clamping rings IV and 20 connect the outer housing ring 17 to the bearing pedestal 21, 21a. Three screws 22 enable fine adjustment of the total storage _{is called} within Ά ^^ ^^ ^ £
