Definitions

the invention relates to a slip ring transmitter for the transmission of electrical Currents and / or signals between a stator and a rotor.
slip ring transmitters of larger diameter it is known, the so-called Use coal / coal technology. This is the case with larger ones, for example Generators the case. To do this in the circumferentially closed
the slip rings must be able to define slip rings for electrical contacts have large wall thicknesses, so that threads are sufficiently large can be accommodated.
the object of the invention is based on the prior art to create a slip ring transmitter that works even with a small Diameter in the coal / coal technology is economically producible and can be operated.
an inner ring closed on the circumference is now made from one Non-ferrous metal, especially brass, in an insulating compound as a component embedded in a rotor.
the insulating compound can, for example Be epoxy resin.
the inner ring is assigned to the rotor electrical connection electrically contacted and from here with an end Cable gland connected.
a circumferentially closed one also extends Graphite outer ring.
This outer ring is laterally through Insulating materials fixed that it is perfectly concentric with the inner ring is centered.
a gap is formed, which the different when exposed to heat Expansion coefficients of e.g. Takes account of brass and graphite.
the temperature range between the ambient temperature is up to the maximum permissible operating temperature.
the contact blades can e.g. made from a copper-beryllium alloy and then be thermally treated.
the invention is associated with the particular advantage that the outer ring made of graphite not only small in wall thickness, but also small in diameter can be held. In this way it is possible to be compact Slip ring transmitters with outer diameters of 200mm and smaller ready to provide, in addition to signals, especially measurement signals, also electrical Currents up to about 50 amps can be transmitted.
the invention ensures that now speeds up can be reached at about 60 m / s.
the sliding contact with only one comparatively small force must be pressed against the outer ring to ensure proper signal and / or power transmission.
On low contact pressure leads to significantly less wear and tear ultimately to a longer service life of a slip ring transmitter.
the abrasion is very low, so that inside the slip ring In principle, no pollution can occur and therefore no pollution electrical caused by abrasion-related contamination Short circuits can occur.
the contact lamellae are defined in the circumferential groove by clamping over bars located on the side of the crown.
the measure of claim 4 also contributes to the fact that a perfect power and signal transmission can be guaranteed, without the need for high contact pressure of the sliding contact on the outer ring would.
a particularly advantageous embodiment of the invention is in the Features of claim 5 sees.
Such an embodiment usually has several inner rings coaxially associated with each other and outer rings and sliding contacts assigned to the outer rings.
the inner rings are in an insulating compound in the form of an insulating bush cast.
the outer rings are insulated in the form of Isolation rings spaced apart.
the Swivel arms point in opposite directions.
To an axial to realize compact design are those assigned to each outer ring Swivel arms to the adjacent outer ring in the circumferential direction staggered. A mutual disruptive influence is on this Avoided way.
Each inner ring is via electrical connection lines embedded in the insulating bush to a contact connection at one end of the insulating bush guided. Lines then lead from this contact connection to one front cable gland on the rotor.
the insulating sleeve is on one Hollow shaft of the rotor is fixed by gluing. This is preferably done only on the ends of the insulating bush.
a length section of the hollow shaft which can be made of steel or another material, approximately middle length range of the insulating bush on the circumference with a smaller one Diameter.
the outer rings and the insulating rings are one End of the insulating bushing one after the other on the inner rings or Insulated sleeve pushed.
the insulating bush has one at one end collar on the circumference. At the other end, a disc is against the last insulating ring clamped, so that then all outer rings and insulating rings are securely fixed in position.
the hollow shaft can be in via end bearings Front walls of the stator be mounted.
the swivel arms assigned to each outer ring are each attached to a holder hinged.
This bracket is on a parallel to the axis of rotation of the rotor extending, fixed in the stator support rod by clamping established.
the support rod can, for example, in the end walls of the Stator.
the successive brackets are through the spacer sleeves surrounding the support rod are positioned.
FIGS. 1 to 3 is a slip ring transmitter for the transmission of referred to electrical currents and / or signals.
the slip ring transmitter 1 has a hollow shaft 2 made of steel as a component of a rotor 3. Rolling bearings 4, 5 are provided at the end of the hollow shaft 2, which are inserted into end walls 6, 7 of a stator 8. girth the end walls 6, 7, a cylindrical jacket 9 is fastened by screws 10.
an insulating compound up to the stop on a collar 11, in particular epoxy resin, pushed in the form of an insulating bush 12 and attached by gluing.
the gluing takes place only at the ends of the Insulating bushing 12.
the insulating bushing is in the approximate middle length range 12 provide the hollow shaft 2 with a circumferential recess 13.
a total of nine inner rings 14 are made on the circumference of the insulating bushing 12 Cast in brass.
the inner rings 14 have the same outer diameter as the insulating bush 12 on.
An outer ring 15 is located on the circumference of each inner ring 14 Graphite. Between the outer surface 16 of the inner ring 14 and the inner surface 17 of the outer ring 15, a gap 18 is present, the different coefficients of thermal expansion of the materials of the inner ring 14 and the outer ring 15 are taken into account.
the orientation each outer ring 15 is made via lateral insulating materials, in particular Epoxy resin, in the form of insulating rings 19.
the outer diameter of the insulating rings 19 is smaller than the outer diameter of the outer rings 15.
the inner rings 14 have circumferential grooves introduced into their outer surface 16 20.
the areas 21 of the outer surfaces 16 next to the Circumferential grooves 20 are gold-plated.
contact blades 22 used in the circumferential grooves 20 are, like the figure 3 reveals in more detail, contact blades 22 used.
These contact blades 22 have lateral webs 23 and a central crowning 24.
the crowns 24 are permanently on the inside Surfaces 17 of the outer rings 15. Because of this design, everyone Gap size between the inner rings 14 and the outer rings 15 a contact the inner rings 14 with the outer rings 15 via the contact plates 22 ensured.
Each inner ring 14 is in a manner not shown with a contact connection 28 connected in the radial collar 27 of the insulating sleeve 12. About this Contact connection 28 then makes an electrical connection to one provided on the face of the hollow shaft 2 cable gland 29.
Support rods 30 releasably set.
the support rods 30 extend parallel to the axis of rotation 45 of the rotor 3.
Brackets 31 threaded and clamped.
the axial distance of the Mounts 31 is fixed by sleeves 32 surrounding the support rods 30.
the end sliding contacts 34 made of graphite wear.
the sliding contacts 34 are by tension springs 35 against the outer Surface 36 of the outer rings 15 pressed.
roller bearing 4 designed as a floating bearing is in the by a snap ring 38 End wall 6 set. It also lies against an inner ring collar 39 the end wall 6.
the other roller bearing 5 is on the one hand as a fixed bearing a snap ring 40 and an annular collar 41 on the hollow shaft 2 and on the other via a fixed by screws 42 on the end wall 7 Cover 43 and an annular collar 44 fixed to the end wall 7.
