Definitions
- the invention relates to a collector according to the Preamble of claim 1.
- the latter also applies to metallic reinforcement rings, in particular steel reinforcement rings, the one Plastic insulation layer in a painting, immersion or have received sintering processes. When softening of the plastic threatens to break down the insulation.
- Reinforcement rings made of a common composite material, about glass fiber reinforced plastic formed, have shown themselves to be inadequate.
- the Elongation of the glass fibers when the temperature rises and at high mechanical loads leads to a to "soft" behavior in which the slats in their inclusion in the plastic molding compound start working. This leads to frictional heat again within the collector, to dimensional inaccuracies the collector tread with a higher brush fire and higher mechanical loads due to uneven running of the collector and dancing Carbon brushes.
- the object of the invention is to provide a collector or to create a reinforcement ring that is high mechanical and thermal resilience, for example that of the metallic reinforcement ring, in particular of the steel ring to achieve or use and especially the weaknesses of known metallic ones Avoid reinforcement rings and their insulation allowed.
- this object is achieved by one Collector according to the preamble of claim 1 starting with the characteristic features of the Claim 1 solved. More advantageous in terms of Refinements are made to claims 2 referred to 15.
- support ring gives the insight again that it is a component, the pronounced support functions, namely one Pressure transfer due to the centrifugal force between the metallic clamping ring and the lamella extensions takes over. It is not necessary that such a support ring in turn absorb tensile forces capable - these can be loaded onto the clamping ring will. Of interest is also that the support ring forms a unit that the Clamping ring is fitted. This secures in the Manufacture and assembly of clamping ring and support ring as well as in the handling of the Reinforcement ring for collector production one good graspability and shape retention, as they are in particular for mechanical aids.
- clamping ring and support ring are coherent, expediently even with an interference fit are fitted so that they are not only in the Handling like a common intermediate ring are to be used, but also in use located and highly loaded collector solid unit with good pressure transmission from the clamping ring on the support ring and from this to the slats guarantee.
- the support ring can be made of glass or other ceramic material, to a high temperature and pressure resistance guarantee.
- the finished, molded with molding compound Such a ring is fixed and becomes a collector almost exclusively under pressure, such Extremely high stability can achieve.
- Glass ceramic and others Ceramic materials can be mixed with modern ones Manufacturing production equipment precisely and economically.
- Manufacturing is an even more common technique a support ring made of a fiber composite body , for example made of glass fiber reinforced plastic. It is important that it is highly filled Material deals. In this way, winding bodies with minimized Matrix share of thermoplastic or thermosetting plastic are manufactured, the only inevitable gaps between the fibers takes up, but otherwise the fibers largely directly abuts each other.
- a such a composite can, for example, in a common winding technology to be manufactured as a tube, the fibers being applied with a high tension and adhesive matrix material to the outside squeeze where it's stripped or after hardening can be turned off.
- the high degree of filling of the fiber composite body has itself as extremely important for stability of such a support ring proved.
- the conceptual The concept here is that the glass fibers, which lie directly next to each other and wrapped tightly together are within the collector high local pressure between the clamping ring and a to withstand particularly loaded inner slat webs if the matrix material does not usable strength contribution to deliver more can
- the fibers of a ring so wound keep due to their packing density, their firm Juxtaposition and also because of the long-fiber Determining their position in the circumferential direction Border area for a long time. So that the insulation maintained by the glass fibers, too if there are plastic components in the reinforcement ring are softened.
- a press-formed support ring manage if fiber material under Squeeze pressure in a ring, tube or plate shape is pressed, in a way that the Fibers themselves in a support network brings. These can also be compact and even at Softening temperature of the matrix material is pressure-resistant Intermediate layers between the clamping ring and the inner web create.
- the slat body made of plastic molding compound otherwise encloses the inner region of the clamping ring and limited so that even inadequate Do not avoid interconnected fibers freely or can emigrate.
- the filling material that determines the compressive strength the support ring does not need in fiber form either to be present. Also a granular, plate-like or ribbon-like structure of a suitable material basically appears useful if it is under Use of the smallest possible plastic parts a precise and stable for handling and for the use of temperature and pressure resistant Support ring is to be manufactured.
- the support ring preferably has at least one side has an axial projection over the clamping ring on, so that he goes in with this side first an undercut of the inner webs is inserted can also be a direct touch on the side between the clamping ring and the inner web.
- the clamping ring can be an angled Have cross-sectional profile in order to to produce a lateral positive connection to the support ring and in handling, especially when inserting of the reinforcement ring in a collector and at Press to get a high level of certainty that tension ring and support ring even with rapid temperature changes do not separate from each other or move against each other.
- a metallic tension ring with an angled one Cross-sectional profile is in production relatively easy to obtain because of modern stamping techniques one starting from simple sheet metal plates Allow stamping, initially circular Surface parts deep-drawn into a pot shape to be "punched out” of the To punch out a ring from the flanks of the deep-drawing area. From a pot or Hat profile results in an angled cross-section without special precautions depending on the choice of hole diameter.
- two reinforcement rings are designated by 1, which are coaxial to a central collector axis 2 run and that of a support ring 3 and one Clamping ring 4 exist.
- Collector slats, only one of which Slat 5, for example, in its for the finished The intended location of the collector, with an inner web 6 to the central collector axis 2 continued.
- the inner web 6 has two undercuts 7 and 8, respectively Leave extensions 9 and 10 on the inner webs. These extensions 9 and 10 are of the reinforcement rings 1 enclosed, so that the slats in particular not centrifugal from the central axis of the collector 2 Dodge outwards.
- finished collector is one of dash-dotted Lines 11, 12 and 13 marked cross-sectional area with a plastic molding compound (not shown) filled so that a cylindrical ring body is formed.
- the support ring 3 consists of a glass fiber material highly filled fiberglass-plastic composite, in which the one matrix plastic is kept so low that he the fiberglass material lie firmly on top of each other leaves.
- the support ring has a simple ring shape with a flat-rectangular cross-section that the Extensions 9 and 10 are firmly gripped.
- the associated clamping ring 4 is a steel ring, through the support ring 3 of the lamellar copper of the inner web 6 and also the actual one Lamellar body is distanced. He helps the support ring a jointly manageable Reinforcement ring 1, being in the interest of a reliable Handling and even more in the interest of one pressure-transmitting connection between the two ring parts (Clamping ring / support ring) a press fit specified is.
- the clamping ring and support ring thus form a rigid one and fixed unit as a reinforcement ring.
- the support ring can be injected into the clamping ring.
- the clamping ring 4 While the support ring 3 in its axial length about the axial length of the undercut 7 or 8 corresponds and thus the undercut in Axial direction covered, the clamping ring 4 is axial staggered over it. This creates an axial Gap 14 as the insulation distance between the clamping ring 4 and lamellar copper. On the other hand the clamping ring 4 forms a radially inward facing shoulder 15, the support ring 3rd engages behind and with the clamping ring 4 axially protrudes beyond the support ring.
- This shoulder 15 creates a good dimensional stability of the Clamping rings 4 against oval deformation, but offers on the other hand also the possibility with machine Handling the reinforcement ring 1 this harmless to grasp and uncritically in a ready-to-install Press in the slat set.
- the arrangement thus created can be described below with plastic molding compound to a finished collector fill in.
- the armoring ring 1 is then in its location through the plastic molding compound held and on its outer circumference as well in the space 14 by plastic molding compound isolated from the lamellar copper.
- Fig. 2 are two (mutually matching) Reinforcement rings 16 shown in cross section, and again only partially in association with one reproduced lamella 5.
- the reinforcement rings 16 each comprise an inner support ring 3 and a clamping ring 4, each with the support ring 3 and the clamping ring 4 according to FIG. 1 match.
- An additional outer support ring 17 encloses the clamping ring 4 with a press fit and is thus an integral part of the reinforcement ring 16.
- This Support ring 17 also ensures pressure support of the slats 5 towards the inside, so that they do not for example due to special external loads dodge inside and thus an oval deformation inside the collector and an additional one Loading of adjacent slats in the sense of a Evasion evoke to the outside.
- Fig. 3 is again a slat of the previous considered type, which (like all remaining slats arranged in a ring Collector) held together by reinforcement rings 19 should be, which from a support ring 3 (with the support ring corresponding numbering in Fig. 1st and FIG. 2 in agreement) and a clamping ring 20 exist, which is different from the tension rings considered essentially distinguishes in that he has a very large cross-sectional angle 21 having outside of the undercuts the slat extends radially inwards is. This cross-sectional bend gives this Clamping ring 20 has a high level of rigidity against oval deformation and elastic natural vibrations.
- the reinforcement ring 27 has a cross section U-shaped clamping ring 28 on the corresponding Extension 9 or 10 of the slat 5 radially outside as also encloses radially inside.
- a pressure-resistant connection by one Support ring 29 or 30 with a flat rectangular cross section made so that the extension 9 and 10th as if clamped between parallel jaws is and does not bend under load and thus more or less from the hold of the clamping ring 28 can "slip out”.
- the clamping ring 28 has on it formed by a U-leg End face holes 31 that allow easy passage of plastic molding compound when pressing.
- FIG To contrast clamping ring 32 in which the second Support ring 29 and, accordingly, the bracket function is eliminated. So with only one support ring 30 just a radial hold function, namely against loads acting in the direction of centrifugal force given. However, the U-shaped cross section creates of the corresponding clamping ring 28 is high Load bearing and inherent rigidity. At the same time is able to do it, even in the manner of a ring to act on the inside bore of a such collector against overload when pressed braced on a shaft.
- the support ring a component that mainly requires pressure and is therefore good from ceramic materials is to be manufactured. Especially at first production separate from the clamping ring simple and advantageous manufacturing options. Finally, pressing together corresponds to Clamping ring and support ring modern, fast and labor-saving manufacturing requirements and holds the support ring under a favorable for its task Preload.
