Definitions
- the invention relates to a rolling tool for producing a crowned toothing on a gear by transverse rollers, in particular for at least partially compressing the teeth of the gear, with a tool body having radially outwardly projecting tool teeth for the meshing engagement in the toothing of the gear to be rolled a device for rolling the teeth of a gear, in particular for at least partially compressing the toothing of the gear, with two gear-like rolling tools for meshing engagement in the toothing of the gear, wherein the
- Rolling tools are each held in a holding device, which are each arranged on a roller spindle, a method for at least partially compressing the teeth of a gear by transverse rolling of the teeth under meshing engagement of teeth of a tool toothing of two rolling tools, and a gear with a teeth having spur teeth wherein the teeth have in the region of tooth flanks extending in the axial direction of width convexity with convex curvature.
- the pivotally mounted rolling head can be swung out with the value of the desired crown in one or more directions from its zero position on the rolling axis. It is thus possible a radial crowning of the toothing or a longitudinal crowning, that is, axial crowning, the teeth to produce.
- the disadvantage of this is that an additional wobbling motion is performed, whereby precision gears are difficult or impossible to produce.
- the latter has a toothing produced by linear grinding and arching of the tool insert, the tooth shape of which is complementary to the tooth form of the crowning toothing.
- the production of the tool insert can be done in such a way that it generates on a flat, plate-shaped insert blank with flat major surfaces by linear grinding a toothing with straight teeth and then attached the insert to the rack so that for working with the tool gives the desired, complementary to a crowned tooth shape of the teeth.
- the disadvantage of this is that the tool in the continuous It is difficult to obtain a toothing which has low tolerances, on the other hand, the tool insert itself suffers from the constant bending stress, even if the material has elastic properties due to the required bends in the tool insert.
- This is achieved by the above-mentioned rolling tool, wherein the tool teeth in the tooth flanks in the axial direction are at least partially hollow ball, regardless thereof by a rolling tool, wherein the tool body in the axial direction of a compression region and a separate region for generating the Irregularity on the toothing of the gear has, independently thereof by the aforementioned device in which the rolling spindles and / or at least a part of the holding means are pivotable, independently thereof by the method in the compaction with rolling tools according to the invention or with a device according to the invention for rolling the toothing of a gear is performed, and by a gear in which the width crowning has a progressive course of the radius of curvature, wherein the radius of curvature starting from a vertex portion of the curvature becomes larger in the area of the transition to end faces of the gear.
- the formation of the width crowning in the course of so-called hard fine machining or by a separate operation can be omitted. It
- the design of the rolling tool with a separate compaction area ensures that the tool production can be simplified and thus the rolling time is practically not extended or insignificantly extended - part of it is further that the more expensive rolling tool can be used for the production of crowning if the compression area of the tool breaks, which is more expensive because these tools are usually produced by grinding on CNC profile grinding machines Wide crowning of the tooth flanks on helical gears suitable in that the gear to be produced is held axially immovable.
- the geometry of the crown can be adjusted by the Einschwenkong, also the attachment of the width crowning during rolling is possible even without expensive rolling tools, so so conventional from the prior art known cylindrical rolling tools also can be used.
- the formation of the width crowning in the compression process of sintered gears by transverse rolling is possible, which in turn a Taktzeitneutraltician is achieved.
- the advantage is achieved that relatively easy arbitrary waveforms can be generated by the rollers.
- the shape of the crown can also fulfill polynomial functions in addition to the forms mentioned above.
- the hollow-bulbous region may have at least two mutually different radii of curvature in the radial direction in order to obtain a better contact pattern of the toothed wheel.
- a plurality of hollow-spherical regions are arranged one behind the other on the tooth flanks in the axial direction. This multi-trackedness of the rolling tool enables simultaneous machining of several gears. On the other hand, it is thus possible to carry out different processing steps of the processing of the toothing with only one rolling tool in a single gear.
- a web is formed between two adjacently arranged regions. It can thus improve the directional stability when rolling gears of multiple gears. At least two of the plurality of hollow-crowned regions may have a mutually different, concave curvature in the axial direction, as a result of which the width crowning of the toothing of the toothed wheel can achieve greater accuracy with respect to its geometry, since the machining in several individual steps enables a smaller deformation dimension.
- the sequence of the differently concave curved, hollow-spherical areas is designed such that the radius of curvature of the hollow crowning increases between the individual processing steps, so that in the successive areas of material in the edge region, ie in the edge region, ie the transition between the end surface and the toothing of the gear, can be spent, whereby the strength can be increased in this edge region.
- At least two of the plurality of hollow-crowned regions may differ in diameter at least in the apex region of the concave curvature. It is thus in turn the compression process in itself better adjustable.
- the diameter variation is formed such that the diameter of the rolling tool in the apex region of the hollow-crowned regions increases from one region to the next region, by which the densities in this region can be increased.
- the diameter decreases from one area to the next area, so that a relaxation zone between two individual compression steps arises before again a larger diameter area follows, and thus higher densities can be achieved at least in the surface area of the toothing of the gear.
- the two regions are separated by a third region having a smaller diameter than the two adjoining regions.
- This intermediate region supports the "threading" during the transfer of the gear from the compaction tool in the region of the forming tool, whereby this transfer smooth and gear-saving, that is gentler for the toothing to be produced, can take place
- Compaction is multi-track and has a width in the axial direction, which is a multiple of the width of the gear to be compacted in the same direction, it can simultaneously several gears, that is, the teeth of the gears, are compressed so that the degree of utilization of the area for the This can be increased in particular, since this shaping allows a shorter cycle time in comparison to the compacting process, but on the other hand, it is also possible to form the compacting process in several stages, the gear being in the process ander changes from one track to the other track by simply moving, where again variants are possible,
- the area for producing the crown is formed on the toothing of the toothed wheel in accordance with the above-mentioned embodiments and variants of the invention, and the advantages mentioned above can be transferred thereto.

But there is also the possibility that this curvature 8 is composed of different areas, for example areas with different radii of curvature. These areas with different radii of curvature can be interrupted by rectilinear areas.
