Definitions

  • the invention relates to a guide roller for wires comprising a coating support in the form of a hollow cylinder which is slidable in the longitudinal direction and is supported on a hub part by a cylindrical stabilising support made from carbon fibre-reinforced plastic (CFP) or metal.
  • a coating support in the form of a hollow cylinder which is slidable in the longitudinal direction and is supported on a hub part by a cylindrical stabilising support made from carbon fibre-reinforced plastic (CFP) or metal.
  • CFRP carbon fibre-reinforced plastic
  • a guide roller for wires of such kind is known from DE 197 17 379 A1.
  • the coating support is made from invar steel and is fixed by shrink fitting on a stabilising support made from a material with a substantial coefficient of linear expansion.
  • the stabilising support In order to slide the coating support on to or off of the stabilising support, at least the stabilising support must therefore be cooled to a correspondingly substantial degree, necessitating significant technical effort.
  • the document describes a construction in which the coating support and the stabilising support are screwed together.
  • mounting and removing the coating support is associated with relatively intensive effort.
  • the object of the invention is to suggest a guide roller for wires that is easy to manufacture, in which the coating support is easy to mount and remove, and which has good radial run-out. Subsequently, it must also be easy to mount and remove while retaining good tolerances in terms of shape and position.
  • the coating support is made from CFP and is attached to the stabilising support via a press fitting, without the use of a threaded connection. Since the stabilising support is functionally decoupled from the coating support, coating may be carried out without the need to approach the coating site with the stabilising support.
  • the coating support is mounted on the stabilising support in directly usable condition in the manner of a module and may then be put into operation immediately.
  • the stabilising support may be of very rigid construction and may be made from either CFP or metal. Together with the hub part, it has excellent strength and dimensional stability.
  • the coating support may be mounted axially onto the stabilising support and removed therefrom very easily using a press at normal temperature. It is not necessary to create a temperature difference between the parts that are to be connected. Even so, the requisite turning moments can be transferred from the stabilising support to the coating support without difficulty, and excellent radial run-out is assured from the outset and under all operating conditions.
  • the coating support is made from CFP, it is possible to create extremely precise fits, definable in advance, in the area of the cylindrically shaped mutual contact surfaces of the two parts. This not only makes storage easier, it also provides the additional capability to produce pre-coated and pre-assembled coating supports as parts for one-time use and transport them to the site where they are to be used.
  • the coating supports and the stabilising supports are in contact with one another via cylindrical surfaces.
  • the coating support may be mounted on and removed from the stabilising support in either of the two possible directions.
  • the coating support and the stabilising support may be in contact with one another via conical surfaces.
  • mounting and removal can only take place in one, predefined direction.
  • the conical surfaces should be at an angle between 0.001 and 5°, preferably an angle between 0.002 and 0.05°, relative to the longitudinal axis.
  • the coating may consist of a polymer or ceramic material.
  • the material used for preference is elastomeric polyurethane that has been applied to the coating support in a casting process and is furnished with the necessary channels for guiding the wires according to its intended application.
  • the materials used must always demonstrate the necessary chemical, thermal and mechanical resistance during its intended use, and in particular good resistance to the effects of glycol.
  • the coating support is made from fibre stands stuck together with synthetic resin and arranged one on top of the other in multiple plies, and aligned at an angle of +/ ⁇ 30 to 60° relative to the longitudinal axis of the hollow cylinder, the fibre strands in the consecutive layers in the radial direction intersecting with one another in the opposite direction.
  • the stiffness and stability necessary for mounting and removal is assured in both the circumferential and the longitudinal directions, and the coated coating support may be used equally well regardless of its mounting direction.
  • the Poisson's ratio resulting from this also makes it easier to mount the coating support.
  • the coating support is preferably made from fibre strands that are stuck together with synthetic resin, arranged one on top of the other in multiple plies and aligned at an angle of +/ ⁇ 40 to 50° relative to the longitudinal axis of the hollow cylinder, the fibre strands in the consecutive layers in the radial direction intersecting with one another in the opposite direction.
  • the coating support may also contain at least one layer in which the fibre strands are arranged at an angle of 80 to 90° relative to the longitudinal axis of the hollow cylinder.
  • the peripheral layer formed thereby lends the coating support particularly good stiffness and stability in the circumferential direction, which is beneficial for enabling the transfer of high turning moments from the stabilising support to the coating support.
  • dimensional stability is supported, which helps substantially to ensure good positional precision of the grooving arrangement.
  • both the stabilising support and the coating support are made from CFP, they may have constructions differing from each other reflecting their different technical functions.
  • the overall radial thickness of the stabilising support is at least three times greater than that of the coating support.
  • the overall thickness of the stabilising support is preferably at least five times greater than that of the coating support.
  • the differing overall thicknesses reflect the fact that the stabilising support is dimensioned primarily from the point of view of the bending load it has to withstand, and the coating support is primarily dimensioned to satisfy the requirements of the press-fit seating.
  • the stabilising support and the coating support are able to complement one another particularly well after mounting through the properties these constructions lend to them.
  • the wall thickness is also considerably greater than that of the coating support.
  • the coating support advantageously has a wall thickness that is between 0.5 and 8% of its outer diameter, preferably between 1 and 3% of its outer diameter.
  • a lightweight coating support may be produced, coated and treated easily and with low production costs.
  • the flanges on the frontal surface may either be in flush contact only with the radial inner side of the stabilising support or they may be provided with a circumferential collar that covers the frontal surfaces of the stabilising support.
  • the collars should have the same outer diameter as the stabilising support. This makes it easier to mount the tubular coating support on the stabilising support repeatedly without causing mechanical damage to the frontal ends of the stabilising support. In particular, this prevents the fibre or plastic components from becoming detached from the CFP material and being carried into a gap that is formed between the coating support and the stabilising support.
  • the stabilising support may be braced radially between the flanges on the frontal surfaces by at least one further flange. This prevents oval deformations from occurring under one-sided loads.
  • the flanges and the stabilising support are advantageously also affixed by adhesion with synthetic resin, and are thus attached to each other immovably. If the stabilising support is made from metal, it is practical to weld the parts together similarly.
  • the stabilising support is advantageously delimited by a surface that has been calibrated with rotational symmetry on the outside in a grinding process and has a slightly conical or cylindrical shape. This helps to achieve a press fitting that is sufficiently tight but still detachable.
  • the inner cylindrical surface of the coating support is calibrated extremely precisely anyway, due to the manufacturing process. Production is effected in a winding process, in which the fibre strands, soaked in synthetic resin are wound onto a conical or cylindrical mould core and are fixed permanently by the subsequent solidification and curing of the synthetic resin.
  • the coating support may be delimited on the outside by a cylindrical surface that has advantageously been calibrated with a “peel ply” in the winding process, and has been also been roughened in the same process.
  • a cylinder surface is produced in a final process step by winding a polyamide tissue without synthetic resin or a similar material onto the as yet non-rigid, final winding ply of resin-soaked CFP and forcing it into the last winding ply by prestressing.
  • the outermost ply of the coating support may be calibrated and roughed as well or additionally thereto in a grinding process after curing. This makes is possible to apply an extremely precisely dimensioned coating of elastomeric polyurethane to the coating support and to embed the coating in the roughened surface of the coating support particularly firmly.
  • the coating may be applied in a casting process.
  • FIG. 1 shows a longitudinal section through a guide roller for wires
  • FIG. 2 shows a longitudinal section through a corner area of the guide roller for wires shown in FIG. 1 .
  • the guide roller for wires of which a longitudinal section view is represented in FIG. 1 is intended for separating thin slices of a hard material, for example a silicon crystal, with the aid of wires.
  • a wire possibly coated with diamond dust or a wetted with a cutting emulsion is looped together in several windings round two or more parallel-axle rollers and the hard material is cut and separated into thin slices at several adjacent and parallel points simultaneously by the wire.
  • the rollers are equipped with a coating support, the outside of which has a polyurethane coating 4 adhering permanently thereto. Coating 4 is provided with grooves extending circumferentially for guiding the wire.
  • Coating support 1 is in the shape of a hollow cylinder and is supported on a hub part by a stabilising support 2 made from CFP or steel, which also has the form of a hollow cylinder. It is provided that coating support 1 is made from CFP and is secured on stabilising support 2 only by press-fitting, without the use of screws or shrink fitting, and that the hub part is in contact with the inside of the stabilising support via radial flanges at least in the area of the frontal surfaces.
  • Coating support 1 consists of fibre strands that are stuck together with synthetic resin and arranged one on top of the other in multiple plies and are aligned at an angle of +/ ⁇ 30 to 60° relative to the longitudinal axis of the respective hollow cylinder, the fibre strands arranged in the consecutive layers in the radial direction intersecting with one another in the opposite direction.
  • the preferred angle is +/ ⁇ 40 to 50°.
  • one layer of fibres extending essentially circumferentially is contained in coating support 1 particularly to increase stiffness and stability in the circumferential direction. Accordingly, there is no likelihood of relative shift of the coating support even during prolonged use.
  • the coating support may be used irrespectively of its direction of rotation, which simplifies mounting considerably. Mounting and removal may be carried out at a normal temperature by mounting the pre-coated, ready-to-use coating support on the stabilising support and removing it therefrom with the aid of a press. In order to fix the coating support, it is not necessary to screw the coating support nor does a special material pairing have to be used with respect to the coating support and the stabilising support, and temperature ranges that may possibly cause the parts to become separated due to the different coefficients of thermal expansion of the coating support and the stabilising support do not have to be avoided in normal use. This significantly simplifies the production, mounting and removal of the tubular coating support as well as the use of the ready-to-use guide roller for wires. At the same time, the roller demonstrates excellent radial run-out.
  • stabilising support 2 and coating support 1 are also constructed differently, provided that the radial layer thickness of stabilising support 2 is at least three, preferably at least five times greater than that of coating support 1 .
  • the radial layer thickness of the stabilising support may be 20 to 60 mm depending on the length of the guide roller for wires.
  • the coating support has a wall thickness equal to 1 to 3% of its outer diameter. As a result, it may be manufactured, coated and mounted without difficulty.
  • the flanges on the frontal faces of hub part 3 are joined flush with the inner circumference of stabilising support 2 by adhesion or welding.
  • the stabilising support may thus be made from CFP or steel.
  • the flanges and stabilising support 2 are stuck together using synthetic resin, it is practical to use a resin that is chemically compatible with the resin used to stick the fibre strands of the coating support and the stabilising support together.
  • the stabilising support may be braced between the metal flanges on the frontal surfaces by at least one further metal flange to prevent oval deformations from occurring under the pressure of prolonged one-sided loads.
  • the number of additional flanges may be altered according to needs.
  • Stabilising support 2 is delimited on the outside by a cylindrical surface 2 . 1 , which is calibrated by a grinding process.
  • a cylindrical surface 2 . 1 which is calibrated by a grinding process.
  • Coating support 1 is delimited on the outside by a cylindrical surface 1 . 1 , which has been given a fabric structure by a peel ply that has been removed previously and/or has been calibrated and roughed in a grinding process to ensure that the polyurethane coating is particularly securely embedded and to enable the profile of the coating to be formed extremely precisely.
