Abstract
A collar and a torque transmission apparatus having a collar. The collar may have a set of collar teeth. Each collar tooth may include a first end surface, a second end surface, a first collar side surface, and a second collar side surface. The first and second collar side surfaces may be concave from the first end surface to the second end surface.
Claims20
A torque transmission apparatus comprising:
- a shaft that extends along an axis and has a shaft spline;
- a collar that includes:
- a collar hole that is disposed along the axis and receives the shaft;
- a collar spline disposed in the collar hole that mates with the shaft spline;
- and
- a set of collar teeth that are disposed opposite the collar hole, wherein the collar teeth include:
- a first end surface that extends away from the axis;
- a second end surface that extends away from the axis and is disposed opposite the first end surface;
- a first collar side surface that is concave between the first end surface and the second end surface;
- and
- a second collar side surface that is concave between the first end surface and the second end surface, wherein the second collar side surface is disposed opposite the first collar side surface;
- and
- a first drive component that is selectively engageable with the collar, the first drive component including:
- a first opening that receives the collar;
- and
- a first set of teeth that are disposed in the first opening that are selectively engageable with the set of collar teeth, wherein each tooth of the first set of teeth includes:
- a first end;
- a second end disposed opposite the first end;
- a first side surface that is convex from the first end to the second end;
- and
- a second side surface that is convex from the first end to the second end, wherein the second side surface is disposed opposite the first side surface, and the first side surface engages the first collar side surface or the second side surface engages the second collar side surface when the first set of teeth meshes with the collar teeth;
- and
- a first root radius at the first end and a second root radius at the second end, wherein the first root radius is greater than the second root radius.
