Abstract

An assembly for improving a connection between splined assemblies generally includes first and second assemblies each having at least one spline thereon, an integral fastening assembly for axially fastening the first assembly with respect to the second assembly, and a biasing assembly for asserting a force to oppositely rotationally dispose the first and second assemblies with respect to one another. In an embodiment, the first and second assemblies are annular plates. A method for improving a connection between splined assemblies generally includes asserting a bias upon first and second assemblies such that are oppositely rotationally disposed with respect to one another. In the above method, the first assembly and the second assembly each have at least one spline, an integral fastening assembly for axially securing the first and second assemblies, and a biasing assembly. In an embodiment of the above method, the first and second assemblies are annular plates.

Claims (20)

1. An assembly for improving a spline connection comprises:

a first assembly comprising a first inner circumference and a first at least one spline disposed on said first inner circumference;

a second assembly comprising a second inner circumference and a second at least one spline disposed on said second inner circumference;

an integral fastening assembly arranged to axially fasten said first assembly with respect to said second assembly; and,

a biasing assembly arranged to oppositely rotationally dispose said first and second assemblies with respect to one another.

2. The assembly of claim 1 wherein said first assembly and said second assembly are each annular.

3. The assembly of claim 2 wherein said biasing assembly is arranged to rotationally misalign said first and second at least one spline.

4. The assembly of claim 2 wherein said biasing assembly is configured to have a range of motion and said first and second at least one spline are alignable within said range of motion.

5. The assembly of claim 2 wherein said biasing assembly comprises at least one compression spring and at least one spring receiving assembly, said at least one compression spring and said at least one spring receiving assembly are tangentially disposed about said first and second assemblies.

6. The assembly of claim 5 wherein said at least one spring comprises first and second ends connected to said first and second assemblies, respectively.

7. The assembly of claim 6 wherein said at least one spring receiving assembly comprises a first pin on the first assembly and a second pin on the second assembly, where said first and second pins are arranged to receive said first and second ends, respectively.

8. The assembly of claim 7 wherein said first pin is oriented in a first rotational direction and said second pin is oriented in a second rotational direction opposite said first direction.

9. The assembly of claim 1 wherein said fastening assembly comprises a protruding member disposed on one of said first and second assemblies and a receiving aperture disposed on the other of said first and second assemblies.

10. The assembly of claim 1 wherein said first assembly is rotatably securable to said second assembly.

11. The assembly of claim 1 wherein said first plate assembly is translationally securable to said second plate assembly.

12. An assembly for improving a spline connection comprises:

a first assembly comprising a first inner circumference, a first outer circumference, a first at least one spline disposed on said first inner circumference and a friction material disposed on said first outer circumference;

a second assembly comprising a second inner circumference and a second at least one spline disposed on said second inner circumference;

an integral fastening assembly arranged to axially fasten said first assembly with respect to said second assembly; and,

a biasing assembly arranged to oppositely rotationally dispose said first and second assemblies with respect to one another.
