Definitions
- the invention relates to a spacer ring according to the preamble of claim 1.
- DE 38 07 310 shows an assembly which is formed from a gear shaft portion of a plurality of gears on the transmission shaft portion and a spacer ring.
- the spacer ring is arranged axially between two gear wheels mounted on the gear section by means of a loose-wheel bearing and holds these axially at a distance.
- Axial distances between two gears for example, necessary to maintain axial clearance for the mobility of switching elements, with which the gears or other components are operated, or to secure space for the arrangement in the transmission.
- switching elements are, for example, components of synchronous shift clutches, with which these gears can be selectively coupled to the transmission shaft rotatably.
- the spacer rings are preferably provided as spacers between two toothed wheels adjacent to one another on a gear shaft section. It is also conceivable that the spacers as a spacer between a gear and another transmission element, such. As a gear housing, a shaft shoulder, a bearing or the like, are arranged. Gears are both on the transmission shaft section, z. B. by Press fit, fixed or integrally formed with the transmission shaft portion and thus not rotatable to the transmission shaft portion gears or rotatably mounted on the transmission shaft portion gears. The latter are z. B. referred to as a gear wheel or idler gear and often rotatably supported by Wälzlagerun- stored on the transmission shaft sections. It is also conceivable that the spacer sleeve is arranged between a gear wheel firmly seated on the transmission shaft section and a loose wheel.
- the spacer also retains any other gear elements, such as disk-shaped components or gearbox bearings, which are seated on a gear shaft, on shaft sections or similar elements, at a distance and / or supported on housings or shaft shoulders. It is also conceivable that the spacer ring holds two oppositely biased angular contact bearing assemblies, for example in axle drives at a distance.
- Spacers are exposed in certain arrangements briefly or permanently high axial forces. These forces act, for example during assembly on the spacer ring when it is loaded during pressing in the assembly, for example, together with gears or other transmission elements by the pressing forces with. Such assembly forces are in the assembly in the order of 60 - 8OkN. Between prestressed inclined bearings spacer rings are often permanently loaded axially. For such applications, the spacers must be designed axially highly resilient.
- JP11-303947AA shows a spacer ring which engages around at least one gear shaft section on the circumferential side of the rotation axis and at the same time holds at least one gear element in the form of a toothed wheel to a rolling bearing on a shaft section of a drive shaft at an axial distance.
- the spacer ring has a section which is rectified with the axis of rotation and has the contours of a hollow cylinder.
- the hollow cylinder is circular-cylindrical.
- No. 7,036,391 B2 shows two spacer rings of the type from hollow cylindrical sections in an axially prestressed bearing arrangement of a driven drive.
- the outline is to be understood as meaning the lines surrounding the body of the spacer ring section, which stand out from the background for the viewer when viewing this section. It means, therefore, the silhouettes considered from different directions, which make it possible for the viewer to determine the basic form of the basic body, without taking into account details. Details are, based on the overall profile, depressions or elevations or in the direction of concealed depressions as the openings, which actually reflect the exactly considered contour, but do not change the general nature of the body.
- a circular or polygonal-shaped hollow cylinder still has the basic shape or the outline of a hollow cylinder even after the attachment of a radial collar, after the introduction of a circumferential groove inside or outside or after the introduction of openings or depressions on the surface.
- the polygon may also have corners that are rounded with convex or concave radii.
- the object of the invention is therefore to provide a spacer ring which combines several functions in itself and is inexpensive to produce.
- the spacer ring is a component made of sheet metal.
- spacer ring is sleeve-shaped as a drawn part.
- spacers are made of metal strips. These spacers are formed for example by a metal strip which is circularly bent, the bending ends are guided towards each other and positively or non-positively or cohesively connected to each other.
- Spacers according to the invention can be produced very accurately. various ne moldings are without additional effort when pulling, cutting or bending to produce. As a result, these parts are particularly advantageous over the prior art from machining production, because in this additional mold elements such as depressions in grooves and collars are only to produce by consuming material removal such as turning, planing and milling and only with a lot of material removal.
- the spacer rings according to the invention can be lighter than the solid rings of the prior art, in particular when the sheet thickness of the bethy, the spacer rings is less than the bridging dimension between inner envelope contour and outer envelope contour of the spacer ring.
- the inner envelope contour is described for example in a solid ring formed by the inner diameter and the outer envelope contour by the outer diameter.
- the bridge dimension in this case is half the difference between outside diameter and inside diameter.
- Bridges for cylindrical and non-cylindrical components is the distance between the outer dimension of the gripped by the spacer ring gear shaft portion in the nominal size at the seat of the spacer ring and the radially outwardly following respective outer dimension of the spacer ring in the nominal size to understand.
- the gear shaft section is, for example, seen in cross-section a triangular, square or another polygonal profile or, as already mentioned, outside cylindrical.
- the inner envelope contour is then described accordingly by a triangle, square or by another polygon.
- the outer envelope contour is a triangle, quadrangle or polygon which corresponds to this and is enlarged on the sides by the bridge dimension or has a different geometry.
- envelope contour is thus not only true for cylindrical cross sections according to the above explanation.
- the dimensions of an inner envelope contour for a spacer ring, which is seated with an interference fit on the transmission shaft section are correspondingly smaller than the nominal dimension of the transmission shaft section at the seat of the spacer ring in the press fit.
- the sheet metal of the spacer rings has groove-shaped depressions at least in sections.
- the groove-shaped depressions are circumferential, but preferably longitudinal depressions.
- the depressions are either put through, embossed or bent, so that during their production only a small proportion (bending portion) of the sheet is plastically deformed.
- the wall sections which delimit the depressions thus bridge the bridging dimension between inner envelope contour and outer envelope contour.
- the sheet which radially delimits the channel-shaped recesses, is as thick in the radial direction as the sheet is thick at the portions adjacent to the recesses.
- Such spacers are sleeves of bending process and methods with bending similar methods and thus manufactured with low degree of deformation.
- the depressions on rings which have a high proportion of plastically displaced material for. B. made by drawing or rolling.
- the sheet metal of the spacer ring, which limits the channel-shaped recesses radially, at least partially in the radial direction is thinner than the sheet metal of the peripherally adjacent portions of the spacer ring in the radial direction. Due to the design and dimension of the sections of the sheet with which the channel-shaped depressions are axially, circumferentially, tangentially or radially limited, if necessary, a radial height is designed which corresponds to a multiple of the thickness of the sheet.
- One, two, but preferably three or more of the channel-shaped depressions extend spirally or in the longitudinal direction of the spacer ring.
- the longitudinal direction are to be understood with the center axis of the spacer ring and the transmission shaft section parallel directions.
- the longitudinal direction is rectified with the (rotation) or symmetry axis. All channel-shaped connections depressions of a spacer ring are in the same direction or are the adjacent alternately opposite either the réellehüllkontur or the outer envelope contour towards the gutter bottom side bounded with the plate of the spacer ring and separated from each other by this.
- the channel-shaped recesses of the sleeve-shaped spacer ring with a substantially cylindrical cross-section are bounded radially inwards or outwards by the metal sheet of the sleeve.
- the spacer ring and the gear shaft portion include channels therebetween through which lubricating oil, e.g. B. from the rolling bearing of a loose wheel for rolling bearing a held by means of the spacer ring at a distance further idler gear can be passed.
- the invention further provides a spacer ring which engages around at least one gear shaft section on the circumferential side of the axis of rotation and at the same time holds at least one gear element on the shaft section at an axial distance.
- the spacer ring consists at least of a rectified with the axis of rotation section with the outlines of a hollow cylinder.
- the section / hollow cylinder is formed from at least one sheet metal strip, the ends of which are bent towards one another on the circumference and fastened to one another.
- Clinching connections are compounds on which mutually form elements with undercuts engage in corresponding form elements with further undercuts.
- Typical compounds of this type are the cross-section dovetailed or button-like connections.
- Such spacers are produced in large quantities and with relatively little effort for tools. During production, there is little waste of material.
- In the preparation of such spacers or at least in the Production of sections with or without a collar sheet metal strips are preferably first cut from an endless belt and profiled.
- the initial length of the sheet metal strip corresponds to the circumference of the finished hollow cylinder at the bending line.
- collars, depressions and openings or similar design features are rolled in, embossed, stamped or chopped.
- the scope describes either a circle or a polygon.
- the section can be made of thin sheet metal with a sheet thickness of 0.2 to 1 mm or alternatively of thick sheet metal with sheet thicknesses of more than 1 mm to more than 5 mm. If the spacer rings are exposed to high axial loads temporarily or permanently, these are to be made axially as stable as possible. Thin sheet tends to buckle or bulge under load easily in this case. In this case, the use of thick-walled spacers is desired.
- an embodiment of the invention provides that the circumferentially closed section has at least one radial opening.
- the volume, and thus the volume-dependent weight, of spacer rings of relatively thick wall can be reduced by the amount of material removed from the spacer to create the aperture.
- a plurality of circumferentially distributed over the section of the openings are provided.
- the material of the sheet from which at least the portion is formed preferably fills a volume whose value is 40% to 60% smaller than that of the volume of space occupied by the hollow cylinder described by the outline.
- the weight of such spacer rings is then increased by the corresponding value of 60% or 40% compared to the theoretical value. reduced table weight (100%) of the hollow cylinder.
- the body edges of the section which are rectified with the axis of rotation, ideally represent the outline of a hollow circular cylinder whose walls are full of material.
- the actual material volume or material weight of the section is then determined by the dimensions and the number of openings. Dimension and number determine the proportion of the volume of material or the proportion of the material weight, which was removed during the production of the openings from the hollow cylinder (void volume) to produce the section.
- the stiffness of spacers against high loads up to 8OkN is particularly secured when the cross section of the webs between the individual openings is formed at least square.
- the dimension (width) of the web which is rectified with the axis of rotation, from the aperture to the edge (front side) or to an adjacent aperture, is preferably at least as great as the radial dimension of the web.
- the mutually bent ends of the metal strip are positively, forcefully or materially connected to each other.
- the frictional connection between the ends is accompanied by an initially mentioned positive connection and is produced, for example, by crimping material at the location of the positive connection, so that the positive connection is permanently unsolvable.
- the material bond is preferably secured by welding.
- the entry of heat during welding of the mutually guided and mutually tangential or circumferentially opposite ends of the metal strip can lead to unwanted deformations of the geometry of the spacer ring when welding a weld that is as long as the rectified with the axis of rotation length of the spacer ring ,
- the length of the spacer ring is large compared to the radial dimension of the wall (wall thickness). This can lead to problems in controlling the welding current of the butt - contact welding point or to quality defects at the weld / weld point, if a weld seam is welded which is just as long as the length of the spacer ring which is aligned with the axis of rotation. Therefore, it is advantageous to reduce the cross section of the weld.
- the object is achieved by welding the section at at least two independent points. It is envisaged that the ends of the sheet metal strip initially have two or more protruding studs whose volume corresponds approximately to the volume of the material which melts during welding for the purpose of connection. After welding, then the ends over the entire length of the section to each other, but are only partially connected to each other.
- the welding current is better controllable and lower, there is less welding fire and the heat input into the spacer ring is lower.
- An embodiment of the invention described above provides that mutually opposite web portions are welded together at the ends of the sheet metal strip.
- the heat input during welding is correspondingly low.
- the material cross sections of the webs can be optimally adapted to the welding requirements, in this case, the mutually facing cut ends of the metal strip, which arise when separating the metal strip from the endless material, designed so that preferably at least one or more openings in each case only proportionally punched out.
- the other portion is formed respectively at the opposite end.
- These openings are open at the ends and separated from each other and / or to the front side in the longitudinal direction (rectified with the axis of rotation) separated by the proportion corresponding web sections or limited.
- the ends of the web portions are abutting surfaces of the respective mutually opposite web portions and are guided towards each other and miteinan- the welded and then form the complete bridge after.
- two or more full openings are enclosed between the ends of the welded sheet metal strip.
- openings in the sense of optimal welding at the junction of the ends of the metal strip are provided.
- Cost reasons in this case are, for example, reasons due to additional costs that result from the extended cycle times for the replacement of several breakthroughs in succession instead of the short cycle times that arise for the replacement of only one or two of the breakthroughs.
- material of the sheet from which the portion is formed preferably fills a volume that is 1% to 5% smaller than the volume of space occupied by the hollow cylinder described by the outline.
- a further embodiment of the invention provides that the section has two facing away from each other planar end faces whose rectified with the axis of rotation distance from each other in nominal size an allowable deviation of max. 1% of the measure of the wall thickness S of the section.
- the wall thickness of the section is calculated from:
