Definitions
- the present invention relates to a ring electrode for a slip ring for transmitting electrical energy between machine parts, at least one of which is rotatable relative to another.
- slip rings find use on a variety of rotating machinery, especially when electrically powered, such as machine tools, certain types of electric motors, and the like.
- slip rings of larger diameter are typically also used in computer tomographs.
- slip rings are used not only for the transmission of drive energy, but also for the transmission of electrical signals.
- circular or annular slip paths which are referred to herein as "ring electrodes,” are attached to a first machine part, and a sliding contact is located on a second machine part, which contacts the slip path or the ring electrode with a certain contact pressure.
- One of the two machine parts is rotatable relative to the other, so that the sliding contact moves along the entire circumference on the surface of the ring electrode while remaining in continuous electrical contact with the ring electrode, whereby the electrodes can selectively contact the outer or inner peripheral surface of the ring electrode They may as well come into contact with a side surface of the ring, which (in the case of a flat ring) has the advantage that this contact surface lies within the same plane Quersc Nuts are preferred because they offer flat bearing surfaces for the sliding contacts.
- Corresponding ring electrodes typically consist of brass or bronze. They are usually made by separating individual rings from a tube of appropriate diameter or by cutting out of solid plates, for example by means of a laser.
- the present invention based on the object to provide ring electrodes and corresponding slip rings, as well as a method for their preparation, which avoid at least one of the aforementioned disadvantages.
- the aim is, inter alia, a simplified production and a lower wear in the use of Rin gelektroden and corresponding slip rings. Furthermore or alternatively, the contact noise and also the contact resistance should be reduced.
- the ring electrode and a corresponding slip ring should especially for use in computed tomography and the like medical devices for the representation of body cross sections suitable and preferably optimized for this purpose.
- a ring electrode which consists of a rod made of stainless steel, which is rolled into a ring and whose free ends are brought together to form a closed ring.
- One advantage of producing an electrode from a stainless steel rod is, inter alia, that virtually no or only a very small material waste occurs, since the rod material only has to be cut off to the length required for a ring.
- Such bar material is often wound on large-diameter rolls and is thus practically available as a continuous material.
- bar material is meant any material having a constant cross-section and a length at least a hundred times the diameter
- rod material also includes wire cross-sections from 16 mm 2 up to cross-sections of, for example, 30x30 mm 2 , without them
- Cross-sectional information should be linked to any restrictions. It is particularly possible with corresponding rolling mills rings with diameters between about 40 cm and 1, 5 m or 2 m with good accuracy, ie with a very good roundness of the ring to produce.
- rod material with a rectangular cross-section, since it offers the possibility of providing sliding tracks, which enable a simple surface contact with the sliding contacts in a simple manner.
- the free ends of the rod formed into a closed ring are then opposite each other on impact.
- the rod is also embedded in an insulating plastic carrier material, so that at most remains a negligible for practical purposes gap between the free ends of the annularly bent rod.
- such a plastic carrier material should be suitably selected so that it has a coefficient of thermal expansion which corresponds as well as possible with the thermal expansion coefficient of the ring electrode made of stainless steel.
- the coefficient of thermal expansion in the range of an operating and transport temperature between -40 and + 80 ° C, at least within a factor 2 should be in the range of the thermal expansion coefficient of stainless steel.
- the rod or rod material used to make a particular ring should preferably have a certain small excess length because this allows the free ends of the overall ring-rolled rod to be superimposed and along a miter cut to the desired one To bring length. As a result, a good overlap for a sliding over the butt weld sliding contact is ensured in each case.
- the corresponding weld seam is not exactly radial with respect to the ring axis, but significantly inclined relative to the radial direction.
- the area of a weld on the ring electrode is preferably smoothed by milling, turning or grinding, so that excessive wear of the sliding contacts in the region of the weld is avoided.
- the ring in the region of the weld can also be annealed to some degree by heating so that this region has substantially the same friction characteristics for the sliding contacts as the remainder of the ring electrode.
- a corresponding slip ring for transmitting electrical energy between a stationary and a rotating machine part, which has an insulating support material, which likewise has the shape of a ring, is inventively characterized in that the slip ring has at least one ring electrode of the type described above.
- the electrode is embedded in the carrier material of the slip ring and has only a slight projection over a corresponding surface of the carrier material.
- a slip ring may also have a plurality of ring electrodes of the type described above.
- the plurality of ring electrodes of a slip ring have different diameters and are arranged concentrically in a common radial plane, i. in a plane perpendicular to the common ring axis.
- the plurality of ring electrodes each have the same diameter and arranged in parallel in a common cylinder surface of the annular or cylindrical support material.
- further ring electrodes can also be arranged on a slip ring, which consist of another conductive material, in particular of brass.
- the corresponding sliding contacts or tap electrodes are in touching contact with the at least one ring electrode made of stainless steel and are preferably metal-containing carbon electrodes.
- carbon electrodes with a silver content of up to 60% or a copper content of up to 75% have proven suitable for combination with stainless steel ring electrodes.
- a plurality of carbon electrodes are arranged as sliding contacts on a common tap rail in a slip ring for each ring electrode.
- the available contact surface between the ring and the sliding contact is significantly increased and it is possible to optimize the contact pressure and the friction and wear highlighted in such a way that an ideal patina for the transfer is formed.
- the low initial wear of the listed material combinations in combination with ambient air humidity leads to a coating of the ring electrodes with the sliding contact material, which has a markedly positive effect on the properties with regard to contact resistance, contact noise and further wear behavior.
- the method according to the invention for producing corresponding ring electrodes has already been implicitly described above and is characterized by using a rod material made of stainless steel, the length of a corresponding stainless steel rod corresponding at least to the circumference of the ring electrode to be produced, rolling the rod into a ring shape with the desired diameter, welding the merged free ends of the rod formed in a ring and smoothing or grinding the weld area on the surface of the welded ring.
- a rod material with a rectangular cross-section is preferably used.
- the preferred materials for the stainless steel of a ring electrode are, for example, stainless steels with high chromium and carbon content, such as are available as steels of the grades X10CM 3 or X20Cr13.
- FIG. 1 shows a plan view of a ring electrode and a corresponding enlargement of an area in the region of a weld
- Figure 5 shows a brush block for the provision of sliding contacts with a plurality of ring electrodes.
- Figure 1 in plan view a schematically illustrated ring 1, which consists of stainless steel and whose cross-section, for example, according to Figure 3 can be square with dimensions of 10x10 mm 2 .
- section A is shown enlarged in the upper part of Figure 1 and indicates schematically by means of a dashed line a weld 8, which extends along a miter cut.
- a rod material with a slight excess length is used and rolled into a corresponding ring and the free ends, which slightly overlap because of the excess, are superimposed and then mitered together along a line corresponding to the weld 8. Subsequently, the cut surfaces are flush against each other and welded, so that the weld 8 has the course shown in Figure 1.
- the surface of the ring is then smoothed by milling or grinding.
- the entire annular surface can also be turned off again when the ring electrode is clamped in a corresponding device or embedded in the slip ring 20 according to FIGS. 2 and 3.
- Figure 2 shows a plan view of a slip ring, which consists of a carrier disk 5 in ring form, which is made of an insulating plastic material, preferably of polyurethane with a mineral filler, wherein the filler ensures that the plastic material has a total of a coefficient of thermal expansion , which is of the order of magnitude of the thermal expansion of stainless steel and in any case deviates by less than a factor of 2 from the expansion coefficient of stainless steel in the temperature range of -40 ° to 80 ° C of interest.
- a coefficient of thermal expansion which is of the order of magnitude of the thermal expansion of stainless steel and in any case deviates by less than a factor of 2 from the expansion coefficient of stainless steel in the temperature range of -40 ° to 80 ° C of interest.
- the carrier disk 5 has a total of four embedded slip rings 1, 2, 3 and 4.
- the common axis 10 of the carrier disc 5 and the rings 1, 2, 3 and 4 is indicated in the center of the disc.
- Figure 3 shows a cross section through the carrier disc 5 with the four embedded Ring electrodes 1, 2, 3 and 4, which protrude slightly over the surface 6 extending in a radial plane.
- the projection of the surfaces of the ring electrodes 1, 2, 3 and 4 with respect to the surface 6 may, for example, be between 1 and 3 mm.
- the ring electrodes 1, 2, 3 and 4, which are square in cross-section, are each embedded more than half in the material of the carrier disk 5.
- FIG. 4 shows schematically a side view of a ring electrode 1, which is in sliding contact with a carbon brush 1 1, the carbon brush, again only schematically, is shown in section.
- the carbon brush 1 1 consists overall of a metal-filled or metal-impregnated graphite block 12, a guide sleeve 13, a cap 14 and a spring 15 which holds the graphite block 12 in engagement with the surface of the ring electrode 1.
- the carbon brush 1 1 is typically mounted in a rail of a brush block 21, as shown in FIG.
- sleeve 13, cap 14 and spring 15 made of an electrically conductive material, typically made of metal and optionally may also be a flat, flexible contact lug or line between spring 15 and graphite block 12 may be arranged with a free end with the cap 14th and / or the sleeve 13 is connected to produce a good electrical contact between graphite block 12 and sleeve 13 and cap 14.
- a plurality of carbon brushes 1 1 are typically connected to an electrically conductive contact rail 22 of a brush block 21, specifically accommodated in each case in a suitable bore of the contact rail 22.
- the sleeve 13 could be pressed or shrunk into a bore of the rail, optionally also be soldered or screwed and is connected in this way firmly and electrically conductive with the contact rail 22.
- a plurality of carbon brushes 1 1 arranged on the same contact rail 22 can simultaneously make sliding contact with the same ring electrode 1 lying one behind the other.
- the holes for receiving the carbon brushes 1 1 on the contact rail 22 follow the arcuate course of a ring electrode 1, but for large diameters of the ring electrode this is generally not required as well as linearly arranged on a short distance carbon brushes despite a slight curvature of the ring electrode stay in touch with this ..
- the adjacent contact rails 23, 24 are shown here without carbon brushes, but of course generally in turn also carbon brushes 1 1, with adjacent Ring electrodes, for example, the ring electrodes 2 and 3 according to Figure 3, come into contact. It is understood that the housing 25 of the brush block 21 is electrically insulating, so that the individual contact rails 22, 23, 24 fastened thereto are electrically insulated from one another.
- the sliding contacts are held under spring bias in contact with the surface of the ring electrodes 1, 2, 3 and 4, wherein either the support plate 5 with the ring electrodes 1, 2, 3 and 4 or a machine part, on which the sliding contacts attached are about the common axis 10 rotates, the sliding contacts are continuously in contact with the surface of the ring electrodes 1, 2, 3 and 4 and in this way can transmit electrical energy or power continuously.
- the method according to the invention of producing the ring electrodes by rolling from stainless steel also has the advantage that rings or ring electrodes of virtually any diameter can be produced from one and the same rod material, as long as the material only rolls to a desired diameter leaves.
- the surfaces have and retain a high quality and the material is extremely resistant to wear and has little friction against metal-containing graphite electrodes, so that the overall wear of the system Slip ring and wiper contact are kept to a minimum while providing excellent performance in terms of ampacity and signal quality.
- the ring electrodes and slip rings according to the invention are particularly suitable for use on medical imaging devices with rotating sensors or sensors or radiation emitters.
