Definitions
- the invention relates to a method for producing a reinforcement ring for commutators and the use of the invention manufactured armouring rings for commutators.
- This problem can be countered, for example, by that combines a metal ring with a glass fiber ring becomes.
- document CH-A-393 507 an armoring ring for commutators, made of an insulating material, preferably a hardened plastic with organic fillers manufactured retaining ring, in which a reinforcing ring embedded in temperable steel with low elongation is.
- This reinforcement ring is only large Workload producible, since either the reinforcement ring in a casting process for the retaining ring in the form for the retaining ring must be included, or the retaining ring to be provided with a circular groove after the appropriate hardening is, which fits extremely snugly on the reinforcement ring have to be.
- Another reinforcement ring is from document GB-A-1 321 059 known, which consists of a steel ring around which in a glass fiber material is wound in an expensive manner then also be subjected to a heat treatment got to. This manufacturing process is therefore quite time consuming and therefore expensive.
- the invention is therefore based on the object of a method to specify for the production of a reinforcement ring for commutators, the high heat resistance, the respective advantages of metal rings and fiberglass rings and at the same time is very inexpensive to manufacture.
- the solution according to the invention has the advantage that during production of the assembled ring only about half each the otherwise usual radial thickness of the glass fiber ring and Steel or metal ring can be used. This allows, that the manufacturing cost of these rings is not material increase, which would be the case if the two rings were nested should be.
- the commutator is designed for thermal and dynamic maximum loads be designed, it is particularly advantageous if the corresponding reinforcement ring has two metal rings, which are attached to the respective end faces of the glass fiber ring are.
- This strength can be increased if the reinforcing ring is designed so that the glass fiber ring both a larger outside diameter and a smaller one Has inner diameter as both metal rings and both protruding areas in the direction of the metal rings in this way are partially offset axially that both on the radial Inner surface of a metal ring of a protruding area as well as on the radial outer surface of the other metal ring the other protruding area is in contact, the two metal rings can advantageously be formed identically.
- the reinforcement rings produced according to the invention can be special advantageous for the reinforcement of the segments in one Commutator can be used, which is described below becomes.
- Reinforcement rings are particularly advantageous one or both radial surfaces of the metal ring partially are covered with glass fiber material, being particularly advantageous these glass fiber parts shifted by means of a punching process can be.
- This punching process can be done separately Punching tool or carried out directly in the commutator itself become.
- the metal ring serves as part of the Punching tool, but serves as the second tool part Circular groove of the punched out segments (as e.g. shown in Fig. 9).
- the reinforcement rings with overhang areas open a very easy way to use a metal ring part desired preload when the reinforcement ring with the glass fiber side ahead into an existing one in the commutator Circular groove is pressed, which circular groove in the axial direction is bevelled so that the fiber ring either to the axis or is tilted to the outer surface of rotation, whereby the metal ring biased either radially inward or radially outward becomes.
- the use of the reinforcement rings according to the invention enables that both the steel ring and part of the fiberglass ring form the supporting part of the reinforcement ring, it being possible that the excess area as an insulation layer between the Steel ring and the copper commutator segments serves.
- the use of the reinforcement rings according to the invention enables it also that the structural designs of the reinforcement to the different quality requirements for commutators can be adjusted.
- the advantage of the constructions is that in all cases a supporting part of the composite Ring is stretched elastically and biased, whereby the commutator the characteristic of the so-called biased Commutators is awarded.
- reinforcement rings produced according to the invention are directly on both sides of the ring the copper segments can be leaned on. This enables drive the ring directly into the grooves of the copper segments can, the ring being wedged into the segments and the This aligns segments in precise radial positions.
- FIG. 1 and 2 is in different views Glass fiber ring or insulating ring 14 shown before it with a Metal or steel ring 12 assembled into a reinforcing ring 10 becomes.
- FIG. 3 to 6 are different in cross section Embodiments of a reinforcement ring 10, 10 ', 10 "and 10"' shown.
- the reinforcement ring 10 shown in Figure 3 is made from the metal ring 12 with a rectangular cross section and the Glass fiber ring 14 with a more angular cross-section, the radial Thickness of the glass fiber ring 14 is greater than the radial Thickness of the steel ring 12.
- the insulating ring 14 has the same or a smaller inner radius than the metal ring 12, and is a radial projection 16 present that axially in such a way by means of a punching process
- Direction of the metal ring 12 offset is that part of the radial outer surface of the steel ring 12 is covered with this protrusion 16, this protrusion 16 but still touches an area of the glass fiber ring 14.
- the reinforcement ring 10 'shown in Figure 4 differs 3 in that an overlap area 18 on the surface facing the axis of a Steel ring 12 'is present and additionally a glass fiber ring 14' has the same or larger outer diameter than a Metal ring 12 '.
- the reinforcement ring 10 '' shown in Fig. 6 has on both End faces of a glass fiber ring 14 "'each a metal or steel ring 12 "'. Since the glass fiber ring 14"' both larger outer diameter as well as a smaller inner diameter than the two, in this case identically trained Steel rings 12 "', there are two protruding areas 16' and 16 "available, which axially shifted in opposite directions are that the one protruding area 16 'on the outer surface of one metal ring 12 "'and the other overhang area 16 "against the inner surface of the other metal ring 12" ' but both protruding areas 16 'and 16 “still one Touch the area of the glass fiber ring 14 "'.
- FIG. 7 shows the use of the reinforcement ring 10 according to FIG. 3 in a commutator 22, which has segments on its outer surface 24 is provided, which are embedded in molding material 26.
- the commutator 22 also has a circular groove 28 which is essentially through recesses in the segments 24 and their circular Arrangement is formed. This circular groove 28 is concentric arranged to the outer circumference of the commutator 22.
- the characteristic of the reinforcement ring lies 10 in that both rings 12, 14 touch on the face, or that the glass fiber ring support part extends to the steel ring 12 the outer layer of the glass fiber ring 14 is shifted and the outer shell of the steel ring 12th clasped and thus connects the two rings 12, 14.
- the way shaped reinforcement ring 10 therefore consists of three parts, of which part of the steel ring 12, the second part of the support part of the glass fiber ring 14 and the third part of the protruding area 16, which serves as an insulation covering of the steel ring 12 and simultaneously connects the steel ring 12 with the glass fiber ring 14.
- the commutator armouring in this example of use is like this executed that the support part of the glass fiber ring 14 elastic on the anchors of the segments, for example made of copper 24 is raised. That from the elastic expansion of this Partly resulting force causes a force component the segments 24 in the direction of the axis of the commutator 22 press the segments 24 on through the protruding area 16 formed insulation jacket of the steel ring 12, which thereby compressed and clamped firmly. The steel ring 12 is thereby subjected to pressure, whereas the supporting part of the glass fiber ring 14 is extended and tensile.
- the reinforcement ring 10 ' has one Steel ring 12 'with a rectangular cross-section, the axial height is greater than its radial height.
- the commutator armor is like this according to this application example executed that the original support part of the fiberglass ring 14 'with the outer circumference over the cone in the circular groove 28' the segments 24 'of the commutator 22' in the radial direction is pressed inside.
- the steel ring 12 ' is by means of deformation the armature of the segments 24 'is stretched radially outwards and thereby in a prestressed state and firmly against displacement clamped.
- the axial height of the steel ring 12 ' is greater than the height of the insulation layer formed by the protruding area 18, see that the space between the inner shell part of the steel ring 12 'and the anchors of the segments 24' with a heat resistant Potting compound is filled, causing a detachment of the Additional segments 24 'of the commutator 22' at high temperatures is prevented.
- the reinforcement ring assembled for this application example 10 consists of a steel ring 12" rectangular cross-section, the axial ring height being greater than the radial height of the steel ring 12 ".
- the peculiarity lies in the fact that the touch both rings 12 “and 14" on the front, or that the Support part of the glass fiber ring 14 "in the steel ring 12" extended is, the inner and outer layer or protruding areas 20 of the glass fiber ring 14 "in the direction of the steel ring 12 "and part of the axial height of the inner and the outer casing of the steel ring 12 ".
- the commutator armor according to this example of use is like this executed that the reinforcement ring so shaped and assembled 10 "in cutouts formed in a circular groove 28" Segments 24 "is hammered in and by means of the deformation of the Anchor of the segments 24 "in the outward direction additionally fastened becomes.
- the commonality and the advantage of using the reinforcement rings according to these statements is that by the reinforcement rings the commutator segments to each other exactly defined distance and at the precisely defined diameter be connected to the molding compound before casting.
- the reinforcement ring used for this application example corresponds to the reinforcement ring 10 'shown in FIG.
- This Reinforcement ring 10 ' consists of the steel ring 12' rectangular Cross-section, the axial ring height greater than that radial thickness of the ring is.
- the peculiarity of this application example is that that the two rings touch on the face, or that the Supporting part of the glass fiber ring 14 'extends the steel ring 12' with the inner layer of the glass fiber ring 14 ' is shifted and part of the axial height of the inner shell of the steel ring 12 'clasped.
- This commutator armature is intended for commutators that composed of copper segments and intermediate insulation slats are.
- the insulation slats are between the anchors of the segments 24 "'extended and serve the Prevention of the armoring ring 10 'in the initial position returns, both the steel ring 12 'and the glass fiber ring 14 'is biased radially outwards.
- the reinforcement ring assembled for this application example 10 "' consists of two steel rings 12"' right angle Cross-section and a glass fiber ring arranged between them 14 "'.
- the commutator armor according to this example of use is like this executed that the reinforcement ring so shaped and assembled 10 "'in cutouts formed in a circular groove 28"' the segments 24a is turned in and by means of the deformation the anchor of the segments 24a in the outward direction additionally is tensioned.
- This deformation can be caused either by Caulking a notch-shaped groove 27 or generated by bending become.
