Definitions
- the invention relates to a method for producing periodic tooth flank modifications, wherein a tool generates at a relative to a tooth flank of a tooth of a workpiece first stroke along a rotated by a helix angle ß to a central axis of the workpiece axis, which generates an enveloping plane.
- Periodic tooth flank modifications and / or periodic excitation corrections provide a special solution that allows complete elimination of the gear excitation of a spur gear pair for a given design load, in addition significantly improving a wide load range in the design load environment.
- This form of tooth flank modification also allows a separate optimization of the load capacity of the given Stirnradcruung and the treatment of individual harmonic components of the excitation function of the meshing, when executed sinusoidal.
- the intervention field is unambiguously described by a periodic tooth flank modification, which is also referred to as periodic excitation correction, amplitude, period, phase length and orientation
- periodic tooth flank modification which is also referred to as periodic excitation correction, amplitude, period, phase length and orientation
- the predetermined macro- and microgeometry of the gearing and the harmonic to be treated of the excitation function of the meshing engagement The period depends only on the treating harmonic of the meshing engagement and has a length equal to the length of the engagement pitch for the fundamental harmonic and a length equal to the length of the whole divisor of the engagement division for the corresponding higher-harmonic components Every harmonic component of the excitation function
- the tooth engagement has its own phase position, which also depends on the macro- and micro-geometry of the toothing.
- the orientation of the periodic tooth flank modification corresponds to the
- a feature of the periodic tooth flank modification is that each individual touch line has a certain amount of correction, i. H. all points of a given line of contact are offset by the same amount, which may also be zero in the normal direction with respect to the plane of engagement.
- Tooth flank arises from a sequence of Hüllitesen.
- One known as hobbing continuous process has the advantages of achieving a high chip rate for wide gears.
- the enveloping body of the hob is a cylindrical involute screw.
- the cutting movement is performed by the rotating cutter.
- spur gears cutter and workpiece relative to each other in the direction of the workpiece axis, ie here a center axis, moved while the rolling movement is performed simultaneously.
- Hobbing is often used in the pre-toothing of gears in series production.
- this method is used in the pre- or final toothing of workpieces with soft, tempered and hardened large, special and splined.
- the Wälzdorfen is known that is also classified as a continuous rolling process.
- the cutting wheel and the workpiece such as the wheel and the mating gear of a spur gear, roll together.
- the cutting wheel carries out the cutting movement due to its reciprocating thrusting motion. With straight toothing, the impact movement runs in the axial direction of the workpiece.
- the helical cutting wheel performs a helical cutting movement corresponding to the helix angle .beta. To be generated. The result is a straight or helical gear whose flanks are tapered backwards.
- the cutting movement ie a vertical movement
- the cutting comb is lifted off.
- the workpiece is rotated by one tooth pitch.
- the tool is a rack whose flanks are cleared to the rear. These are called cutting combs.
- the milling cutter has the profile of the tooth gap to be milled.
- the rotating cutter and the workpiece are moved toward each other in the direction of the workpiece axis.
- the workpiece does not rotate. Only after completion of a tooth gap, the expectant gear is further rotated by one division.
- the workpiece executes a continuous rotary movement, which corresponds to the helix angle ⁇ .
- Form milling can be performed with end mills or be performed milling. Although advantageously, inexpensive and easy to be dressed tools can be used; for different involute curves but you need different arches. To achieve a tooth flank modification, the so-called.
- Wälzschleifen in which the involute profile formed by rolling the gear in two plate-shaped grinding wheels, offers to. Stencils are used or a corresponding control is used. Finally, a topological cut is made with the help of the so-called O-method or the Niles method.
- the grinding wheels are, for example, arranged in parallel in a so-called 0-process.
- the grinding feed in the axial direction performs the workpiece. It is moved back and forth in the axial direction.
- the division takes place at the end of the feed path. In each operation, two tooth flanks are guided simultaneously.
- the chip delivery is done by the engagement of the grinding wheels.
- the disadvantage here is the provision of different rolling arches in the tool. With a profile grinding process from today's perspective, no topological
- the object is achieved in that the enveloping plane is aligned orthogonally to an engagement plane, so that during the first stroke a machining track is created by the machining action of the tool on the workpiece exactly along a first contact line for a first corresponding rolling position, wherein the first contact line preferably simultaneously forms a second contact line corresponding to the first contact line between the workpiece and an arbitrary rolling partner of the same helix angle ⁇ , wherein the tooth flank modification by a delivery by the value z u of the tool in the normal direction of the tool and / or workpiece along the first Touch line is created and the workpiece performs no rolling movement during the single stroke.
- the object is also achieved by a machine tool that is set up to perform the method.
- a computer-readable medium having instructions that, when executed by a processor, result in control or regulation of a machine tool according to this method solves this problem.
- Such a method produces periodic tooth flank modifications much faster, more accurate, and more reproducible than existing methods. It can also be implemented with significantly less programming and control-technical complexity compared to topological loops, since it is not based on a point contact, but on an enveloping plane. Unlike topological grinding, this process can be implemented by continuous hobbing and the a ° process.
- Touch line compared with a second arranged next to the first line of contact Berlick leads.
- the workpiece is advantageous for the workpiece to be straight or helically toothed. In this way, particularly good efficiencies can be achieved.
- Conventional low-cost machine tools can be used when a machining process is used.
- the workpiece is formed internally or externally toothed.
- FIG. 1 shows an engagement situation between a tooth flank of a tooth of a workpiece and a tool envelope for a single discrete engagement position, ie. H. Wälz ein, represents.
- the tool envelope is a plane in FIG. 1.
- this tool If this tool is brought into any engagement position in normal engagement with a flank of a tooth 1 and brought in the width direction Zb along a helix ß to a center axis 2 of a gear formed as a workpiece 3 and rotated in tooth width direction Zt and in a plane orthogonal to the standard profile level lying linear axis shifted, it creates an enveloping level 4 of the tool edge.
- this first contact line 5 is also a second line of contact between the tooth flank shown and the tooth flank of any partner with the same angle of inclination .beta., is obvious.
- the situation is also illustrated by a tangential to the base circle engaging plane 6 in Fig. 1, in which the first contact line 5, illustrates.
- the amount of the tooth flank modification, ie the correction achieved, for this first contact line 5 can be determined by the feed in the normal direction between the tool and the workpiece 3. In this way, gradually by rotating the workpiece 3 between strokes, the adjacent touching lines, that is, next to the third touching line, can be processed individually in each rolling position.
- the shape of the tooth flank modification in the profile direction may under certain circumstances not be reproduced exactly but as a polygon, so that the accuracy of the method depends on the number of discrete machined rolling positions. In a section along the central axis 2 or the tooth width direction Zb, shows a polygon on the surface of the tooth flank.
- the method described here is to implement particularly favorable over all Wälz compiler, the accuracy of which are the hard fine better suited.
- the process can be used particularly easily by means of partial gear grinding with a conical disk, partial gear grinding with a disk disk in the a ° process and generating grinding with a grinding worm.
- generating grinding with a grinding worm it should be noted here that, depending on the geometry of the workpiece and the tool, a plurality of teeth 1 of the workpiece 3 can be processed simultaneously, so that the periodic tooth flank modifications are division-periodical.
