Definitions
- the Windungsleger rotates about the shaft axis.
- the Winding layer along the shaft axis the rod-shaped rolling stock with Walzgut Irish fed.
- the rolling stock enters the inlet end of the laying tube and exits tangentially from the outlet end so that it is in the form of a series of Rings or turns can be stored on a conveyor belt.
- the Peripheral speed of the outlet end which is proportional to the speed and the Radial distance of the outlet end of the shaft axis is approximately equal to Rolling stock.
- the Windungsleger undergoes at rest with horizontally extending shaft axis a gravity-induced deflection. This deflection is determined in essentially the resonant frequency.
- the resonance frequency limits the speed and thus indirectly the maximum possible rolling stock speed.
- the Resonance frequency is higher, the lower the gravitational deflection of the laying tube holder is at rest.
- the Efindung therefore has the object, a Windungslegerder the beginning mentioned type such that it has the lowest possible Gravity-induced deflection and thus the highest possible resonance frequency having.
- the laying pipe a light metal, for. As aluminum and magnesium, and on its inside has a ceramic layer.
- the laying tube holder but also the laying pipe itself made of a material that has a lower density as steel possesses.
- a rod-shaped rolling 1 by means of a Windungslegers 2 in Form of a series of rings or windings 3 stored on a conveyor belt 4.
- the rolling stock 1 is the turntable 2 with a Walzgut Irish supplied to vW.
- the Windungsleger 2 rotates at a speed n about a shaft axis 5.
- the Windungsleger 2 is doing in a known manner a motor 6 via a transmission 7, usually a deflection gear 7, driven.
- the Windungsleger 2 has a hollow shaft 8, a Laying tube holder 9 and laying tube 10 on.
- the hollow shaft 8 is stored in a sub-camp 11 and a main bearing 12 such is that the hollow shaft 8 about the shaft axis 5 rotatable is.
- the auxiliary bearing 11 and the main bearing 12 are axially spaced.
- the laying tube holder 9 protrudes beyond the main bearing 12. He has a fitting 13, z. B. a connecting flange 13, and a substantially rotationally symmetrical centerpiece 14 on.
- the connecting piece 13 is the laying tube holder. 9 rotatably connected to the hollow shaft 8.
- With the middle piece 14 are a support plate 15, support plates 16, 17 and a compensation structure 18 connected.
- the support plate 15 runs with the laying tube 10. It has connection eyes 19 on which holding elements 20 are attached. By means of the holding elements 20 carries the support plate 15 and thus also the laying tube holder 9 the laying tube 10.
- the support plates 16, 17 support the support plate 15 axially forward and backward from.
- the support plate 15, the support plates 16, 17 and the holding elements 20 together form a centerpiece 14 arranged Supporting structure for the laying tube 10.
- the compensation structure 18 is used to balance the support structure and the laying pipe 10 caused imbalances.
- the laying tube 10 has an inlet end 21 and an outlet end 22 on. Between the inlet end 21 and the outlet end 22 describes the laying tube 10 a three-dimensional curved guideway for the rolling stock 1.
- the inlet end 21 is aligned the shaft axis 5.
- the outlet end 22 has from the shaft axis 5 a radial distance d.
- the rolling stock 1 runs the shaft axis 5, enters the laying tube 10 at the inlet end 21 one and at the outlet end 22 of the laying tube 10 from.
- the outlet end runs 22 at a peripheral speed vU about the shaft axis 5 um.
- the peripheral speed vU corresponds to the Rolling stock speed vW.
- the outlet end 22 thus describes a circle 23 around the shaft axis 5.
- the laying tube 10 is a Guide extension 24 downstream.
- the guide extension 24 In particular, serves the proper storage of the last Windings 3 on the conveyor belt 4th
- the Windungsleger 2 at horizontally extending Shaft axis 5 of the Windungsleger 2 according to Figure 3 a Gravity-related deflection D on.
- the gravitational Deflection D is in Figure 3 the clarity half greatly exaggerated.
- the gravitational Deflection D determines the resonant frequency of the layer 2 in operation.
- the resonance frequency is limited the speed n and thus indirectly the maximum possible rolling speed vW.
- the resonance frequency is the higher the lower the gravitational deflection D of the turntable 2 is.
- the maximum consists of increasing the possible rolling stock speed vW Winding layer 2 not made of steel.
- the laying tube holder 9 at least partially made of a material, which has a lower density than steel.
- materials in particular light metals z.
- aluminum and magnesium in question. Possibly. can also be a fiber reinforced Plastic used. This can be achieved that the gravitational deflection D of the Windungslegers 2 by more than half compared to the gravitational Deflection D 'of a structurally identical Windungslegers made of steel is reduced.
- the laying tube 10 and possibly this subordinate leadership extension 24 can at least partially made of a material which has a lower density than steel. at These parts come due to thermal stress in particular ceramic materials, possibly also composite materials made of light metal and ceramic, in question.
- the laying pipe 10 consists according to the invention of a light metal and has on his Inside a ceramic layer.
- the gravity-induced deflection is essentially of the bending line inclination of the hollow shaft on the main bearing determined. Therefore, if necessary, the center piece 14, possibly even the fitting 13, made of light metal.
- the hollow shaft 8 is made Stole.
- the support plate 15, the support plates 16, 17, the compensation structure 18, the middle piece 14 and even the fitting 13 are made of light metal.
- the laying pipe 10 exists made of light metal and has on its inside a Ceramic layer on.
- the guide extension 24 is in his thermally and mechanically stressed part made of ceramic and otherwise made of light metal.
