Serration having an offset construction point
View Patent ↗A component that is to be mounted so as to be rotatable about an axis of rotation and transmits torque along with a rotating partner includes a first serration that extends about the axis of rotation and is to mesh with the rotating partner which has an adequate second serration mating with the first serration. The first serration has a plurality of teeth which have tooth tips extending substantially in the direction of the axis of rotation and tooth valleys located between the tooth tips. The tooth tips of the first serration each have a meshing edge forming a first line, while the tooth valleys located between the teeth each define a second line. At least two adjacent second lines intersect at an imaginary point lying between the axis of rotation and the maximum circumference of the first serration, in the semicircular surface beyond the axis of rotation.
1. A component for a rotating mounting about an axis of rotation and for torque transmission with a rotating partner, the component having a first spur toothing that extends around the axis of rotation and is provided for meshing with a rotating partner, which has a corresponding second spur toothing that mates with the first spur toothing, wherein the first spur toothing has several teeth with tooth tips extending substantially in the direction of the axis of rotation and tooth troughs situated therebetween, and the tooth tips of the first spur toothing each have one meshing edge which forms a first line, and the tooth troughs situated between the teeth each form a second line, wherein at least two adjacent second lines intersect in an imaginary point that lies in a semi-circular surface region of the first spur toothing on a distal side of the axis of rotation between the axis of rotation and a maximum circumference of the first spur toothing.
2. The component according to claim 1 , wherein the first line, which is situated between two second lines, intersects the axis of rotation.
3. The component according to claim 1 , wherein the first line, which is situated between two second lines, intersects the imaginary point.
4. The component according to claim 1 , wherein the first lines define a plane.
5. The component according to claim 1 , wherein the first lines lie on a jacket surface of a truncated cone.
6. The component according to claim 1 , wherein at least the first lines are curved in a direction parallel to the axis of rotation.
7. The component according to claim 6 , wherein the second lines are furthermore curved in such a way that a flank angle of the respective tooth is constant over its radial extent.
8. Assembly for torque transmission, comprising a component mounted rotatingly about an axis of rotation, which is configured according to claim 1 , and a rotating partner with a second spur toothing, which is meshing peripherally with the first spur toothing, wherein the second spur toothing of the rotating partner has several teeth with tooth tips, which substantially extend in the direction of the axis of rotation, and tooth troughs situated therebetween, and the tooth tips of the second spur toothing each define a meshing edge forming a third line, and the tooth troughs provided between the teeth each form a fourth line.
9. The assembly according to claim 8 , wherein at least two adjacent fourth lines intersect in an imaginary point that lies in a semi-circular surface region on a proximal side of the second spur toothing on a distal side of the axis of rotation between the axis of rotation and a maximum circumference of the second spur toothing.
10. The assembly according to claim 9 , wherein the third line situated between two fourth lines also intersects the imaginary point.
11. The assembly according to claim 10 , wherein the imaginary points of the component and the imaginary points of the rotating partner are respectively disposed on imaginary circles disposed coaxially about the axis of rotation.
12. The assembly according to claim 11 , wherein the radius of each of the respective circles is the same.
13. The assembly according to claim 9 , wherein the imaginary points of the first spur toothing define a first plane perpendicular to the axis of rotation, and the imaginary points of the second spur toothing define a second plane perpendicular to the axis of rotation, with the planes being spaced-apart parallel to each other.
14. The assembly according to claim 8 , wherein means ( 4 ) are provided for effecting a biased meshing of the first and second spur toothing.
15. The assembly according to claim 8 , wherein the assembly is provided between a wheel and a side shaft of a motor vehicle.
16. The assembly according to claim 1 , wherein at least the first lines are curved in a direction opposite to a meshing direction.
