Disclosure of Invention
The aim of the invention is therefore to achieve as great a degree of freedom of linear movement as possible of the tool/tool.
According to the invention, this object is achieved by a gear wheel according to the features specified in claim 1, an apparatus according to the features specified in claim 9 and a method according to the features specified in claim 10.
An important feature of the invention is that the gear has a flat toothing which covers a first radial distance region, in particular with reference to a central axis and/or a rotational axis of the gear, wherein the gear is embodied as a hub part and/or has a centrally arranged recess, in particular hollow, such that the gear can be slipped onto a shaft, wherein the gear covers a first axial region in the first radial distance region, wherein the gear covers a second axial region in a second radial distance region, wherein the second radial distance region is radially spaced apart from the first radial distance region, wherein the second radial distance region is arranged radially inside the first radial distance region, wherein the second axial region comprises or at least overlaps the first axial region, wherein the gear in the second radial distance region, In particular at the hub part neck of the gear, the wall thickness and/or the radial thickness decreases in the axial direction, in particular with increasing distance from the planar toothing, in particular decreases smoothly and/or continuously differentiably as a function of the axial position.
The advantage here is that the tool can achieve as great a degree of freedom of linear movement as possible, since the tool can be guided up to the hub part neck of the gearwheel, in particular in the second radial distance region, and can therefore either be arranged in a manner movable in the direction of the axis of rotation of the tool or be designed very long. The concave, i.e. inwardly curved, embodiment of the hub part neck of the gear wheel allows for the most remote displacement of the tool or for the longest possible tool. Since the envelope surface of the tool is a cylinder, the outer edge of the cylinder locally contacts the hub part neck. The hub part shape thus has the largest hub part material with the optimum milling length and therefore results in a more stable gear body.
In an advantageous embodiment, the gear wheel covers a smaller axial region in the radial distance region arranged between the first radial distance region and the second radial distance region than in the first radial distance region and also than in the second radial distance region. The advantage here is that there is an undercut between the flat toothing and the second radial distance region.
In an advantageous embodiment, the reduced wall thickness or radial thickness is independent of the circumferential direction, with the exception of grooves, in particular keyways, which are arranged on the inner side of the gearwheel. It is advantageous here that the rotor region can be produced simply.
In an advantageous embodiment, the reduced wall thickness or radial thickness is implemented such that: the envelope surface of a tool, in particular a milling cutter, which produces a planar toothing, is brought into contact with the gear, in particular along the outer edge of the envelope surface. The advantage here is that a simple mathematical determination of the hub part neck and thus also a simple production is achieved.
In an advantageous embodiment, the axis of rotation of the tool has a non-zero axial distance with respect to the central axis of the gear and/or the axis of rotation, and/or the axis of rotation of the tool is arranged parallel to the planar toothing and at a non-zero axial height above the planar toothing, in particular above the plane of engagement of the planar toothing with the tool. The advantage here is that the cutting tool projects laterally beyond the flat toothing and can therefore machine the entire width of the flat toothing even with a large axial distance, wherein for this purpose the cutting tool extends up to the hub part neck of the gear, the concave shape of which allows for a cutting tool that is as long as possible, i.e. long enough to machine the entire width of the flat toothing.
In an advantageous embodiment, the reduced wall thickness or radial thickness is implemented such that the circular outer edge of the envelope surface contacts the gear wheel, in particular independently of the rotational position of the gear wheel about its rotational axis and/or central axis, wherein the center of the circular outer edge has a distance, in particular an axial distance, which is not zero with respect to the rotational axis or central axis of the gear wheel, wherein the center of the circular outer edge has a distance, in particular an axial height, which is not zero with respect to the planar toothing, in particular with respect to the meshing region between the tool and the gear wheel, wherein the circular shape of the outer edge is arranged in the following planes: the normal direction of the plane is the axis of rotation of the tool or is oriented parallel to the axis of rotation of the tool. In this case, it is advantageous if only the outer edge of the envelope surface contacts and thus determines the shape of the hub part neck, i.e. the shape of the gear wheel in the second radial distance region. Therefore, simple manufacturing can be achieved.
In an advantageous embodiment, the radially outer surface of the gearwheel in the region of the second radial distance is identical to the region of the surface of the torus revolution body, which can be produced by rotating an arc region about the axis of rotation of the revolution body, wherein the axis of rotation is the central or rotational axis of the gearwheel. The advantage here is that, in a good approximation, a circular arc is sufficient as a shaping, and this circular arc then remains unchanged about the central axis of the gear, irrespective of the circumferential direction. Thus, a circular arc shaped region is a mathematical intersection between the gear and a plane containing the central or rotational axis of the gear. The intersection line is independent of the rotational position of the plane.
In an advantageous embodiment, the axial distance between the axis of rotation of the tool and the axis of rotation of the gear wheel is smaller than the inner radius of the tooth of the gear wheel, i.e. in particular is arranged at a smaller radial distance than the tooth of the gear wheel. The advantage here is that the outer edge of the end face of the envelope surface of the tool can move closer to the hub part neck during the milling of the gear teeth, i.e. almost touch. Thus, an optimal utilization of the cutting edges of the milling cutter can be achieved.
An important feature in the apparatus for manufacturing the teeth of the gear described above is that the tool is connected in a relatively non-rotatable manner to the shaft, wherein the tool is spaced apart from a point arranged on the axis of rotation of the shaft and having a minimum distance from the central or rotational axis of the gear, wherein the shaft contains the point. The advantage here is that the shaft can be supported on both sides of the gear and can therefore dissipate high transverse forces during production.
An important feature in the method for producing a gear tooth is that the gear is embodied as a hub part, in particular as a hollow hub part, having a hub part neck and a flat toothing, in particular wherein the hub part neck is radially spaced apart from the flat toothing, wherein the hub part neck tapers with increasing distance from the flat toothing, in particular with increasing distance measured axially from the flat toothing, wherein the flat toothing is produced with a working region, in particular a cutting region, of the tool, wherein an outer end of the working region in the direction of the axis of rotation of the tool, in particular an outer edge in the direction of the axis of rotation of the tool, contacts, in particular linearly, the hub part neck, in particular independently of the rotational position of the hub part neck about its axis of rotation and/or central axis, in particular, the outer edge is circular, wherein the center of gravity, in particular the center of the circle, of the outer edge has a non-zero distance, in particular an axial distance, from the axis of rotation or the central axis of the gearwheel, in particular wherein the distance is smaller than the inner radius of the planar toothing, in particular smaller than the minimum radial distance of the planar toothing, wherein the center of gravity, in particular the center of the circle, of the outer edge has a non-zero distance, in particular an axial height, from the planar toothing, in particular from the meshing region between the tool and the gearwheel, wherein the outer edge is arranged in the following plane: the normal direction of the plane is the axis of rotation of the tool and/or is oriented parallel to the axis of rotation of the tool.
The advantage here is that the cutting tool can be brought so close to the hub part neck that it contacts the hub part neck during the production of the flat toothing, for example by milling. Thus, the working area, i.e. the cutting area of the milling cutter, can be utilized as well as possible and a high service life can be achieved. The outer edge is the edge of the working area of the tool, viewed in the direction of the axis of rotation of the tool. When the tool is rotated, the outer edge is the end of the envelope surface of the working area of the rotating tool.
Here, contact is also understood to mean adherence to a safety distance, in particular, for example, less than 0.5 mm. When the safety distance is measured parallel to the axis of rotation of the tool, the safety distance is constant along the linear contact area. This therefore enables maximum use of the working face of the milling cutter. In an embodiment according to the invention, the hub part neck can be embodied very rigid due to its shaping and the service life of the milling cutter is high.
An important feature in the method for producing a toothed wheel toothing is that the toothed wheel is embodied as a hub part, in particular as a hollow hub part, having a hub part neck and a flat toothing, in particular wherein the hub part neck is radially spaced apart from the flat toothing, wherein the hub part neck tapers with increasing distance from the flat toothing, in particular with increasing distance measured axially from the flat toothing, in such a way that: in particular, the circular outer edge of the envelope surface of a tool, in particular a milling tool, for producing a planar toothing is in contact, in particular in a linear manner, with the hub part neck, in particular independently of the rotational position of the hub part neck about its rotational axis and/or central axis, wherein the center of the circular outer edge has a non-zero distance, in particular an axial distance, relative to the rotational axis or central axis of the gearwheel, in particular wherein the distance is smaller than the inner radius of the planar toothing, in particular smaller than the minimum radial distance of the planar toothing, wherein the center of the circular outer edge has a non-zero distance, in particular an axial height, relative to the planar toothing, in particular relative to the region of engagement between the tool and the gearwheel, wherein the circular shape of the outer edge is arranged in the following plane: the normal direction of the plane is the axis of rotation of the tool or is oriented parallel to the axis of rotation of the tool.
The advantage here is that the cutting tool can be brought so close to the hub part neck that it contacts the hub part neck during the production of the flat toothing, for example by milling.
Here, contact is also understood to mean adherence to a safety distance, in particular, for example, less than 0.5 mm. When the safety distance is measured parallel to the axis of rotation of the tool, the safety distance is constant along the linear contact area. This therefore enables maximum use of the working face of the milling cutter. In an embodiment according to the invention, the hub part neck can be embodied very rigid and the service life of the milling cutter is high due to the shaping of the hub part neck.
Further advantages emerge from the dependent claims. The invention is not limited to the combination of features of the claims. Other possible combinations of the features of the claims and/or of the individual claims and/or of the features of the description and/or of the drawings may be made apparent to the person skilled in the art, in particular from the task set forth and/or by comparison with the prior art.
Drawings
The invention will now be explained in detail with the aid of the accompanying drawings:
in fig. 1, a gear wheel 5 is schematically shown together with a machining tool 1, wherein the envelope surface of the teeth of the gear wheel 5 and the tool 1 is shown instead of the teeth themselves.
In fig. 2, the tool 1 is shown in engagement with the gear wheel 5, which is cut open so that the concave curvature of the hub part neck 3 of the gear wheel can be seen well.
In fig. 3, the tool 1 is shown in engagement with the gear wheel 5.
Detailed Description
As shown in the drawing, the tool, in particular the milling cutter, is connected to the shaft 2 in a rotationally fixed manner. The gear wheel 5 to be machined is embodied as a hub part and has a hub part neck 3 which narrows in the axial direction in its end region.
The gear wheel 5 has a flat toothing 4, which is spaced apart from the hub part neck 3 in the radial direction. The planar toothing is preferably a helical planar toothing.
The envelope surface of the tool 1 is cylindrical. The imaginary axes of the tool 1 and the shaft 2 have an axial distance a with respect to the central axis of the gear wheel 5 and an axial height h with respect to the meshing plane of the planar toothing 4 of the gear wheel 5.
The tapering profile of the hub part neck 3 is a concave shape which is determined by the envelope surface of the tool 1.
The gear wheel 5 is hollow, so that the gear wheel 5 can be placed over a shaft and can be connected to the shaft in a rotationally fixed manner by means of a key connection. For this purpose, the gear wheel 5 has a keyway on the inner wall of the hub part neck 3, which keyway extends in the axial direction.
The planar toothing of the gearwheel 5 covers a first radial distance region. The gear wheel 5 covers a first axial region in this first radial distance region.
The region of the hub component neck is arranged with the inner wall in a second radial distance region, which is radially spaced apart from the first radial distance region and covers a second axial region in the axial direction, which includes the first axial region.
The gear wheel 5 has an axial narrowing in a radial distance region arranged between a first radial distance region and a second radial distance region. That is, in this narrowing the gear wheel 5 stretches axially less in the first radial distance region and in the second radial distance region.
The region of the flat toothing and the neck of the hub part protrudes axially beyond this narrowed region.
The envelope surface, i.e. the sheathing surface, of the tool 1 is the surface of the spatial area that is required and/or covered when the tool 1 is rotated about its axis of rotation.
The spatial region is a body of revolution, in particular a cylinder. The envelope surface is thus a corresponding cylindrical surface.
During the machining of the toothing, the tool 1 projects toward the hub part neck 3. The tapering shape of the hub part neck 3 is determined by the circular outer edge of the cylinder. In this case, the outer edge is forced to produce the contour of the hub part neck when it comes into contact with the hub part neck.
In this way, the cutter 1 is allowed to approach the hub component neck as close as possible. A better utilization of the tool 1 is achieved with maximum retention of the material of the hub part.
The axis of rotation of the tool 1 is perpendicular to the axis of rotation 8.
The hub part neck 3 projects in the axial direction over the flat toothing 4. The hub part neck thus limits the linear degree of freedom of the tool 1, i.e. the movement of the tool 1 in the direction of its axis of rotation. For this purpose, the shape of the hub part neck 3 is determined by the envelope surface, in particular the circular outer edge of the envelope surface. Other parameters determining the shape of the hub member neck 3 are the axial spacing between the axis of rotation of the tool 1 and the axis of rotation of the gear 5, the axial height between the axis of rotation of the tool 1 and the plane of engagement, the length of the tool 1 and the envelope surface of the tool, i.e. the diameter of the cylinder.
In this way, the hub part neck is embodied in a concave shape. The wall thickness of the gear wheel 5, in particular of the hub part neck 3, tapers in the axial direction with increasing distance from the flat toothing 4. That is, the wall thickness of the hollow gear 5 decreases more and more in this direction with increasing distance from the flat teeth 4. In this case, the hub part shape always represents the maximum possible value of the hub part material in the respective optimum milling position.
The flat toothing 4 is preferably embodied as a helical flat toothing. The teeth of the planar toothing 4 extend in an arc shape, i.e. in the circumferential direction with increasing radial distance. The tool 1 is correspondingly configured as a pinion which cooperates with a helical flat toothing.
