Track nut with increased bearing area
A track nut comprises a main body defining a central aperture with threads disposed in the central aperture, the aperture defining a cylindrical axis and a radial direction, a first end and a second end disposed along the cylindrical axis, and wherein the first end defines an at least partially circular perimeter and the second end defines a generally polygonal perimeter with a plurality of corners, the polygonal perimeter including at least one variable blend portion.
1. A track nut comprising:
a main body defining a central aperture with threads disposed in the central aperture, the aperture defining a cylindrical axis and a radial direction;
a first end and a second end disposed along the cylindrical axis; and
wherein the second end defines a generally polygonal perimeter with a plurality of corners, the polygonal perimeter including a variable blend portion between each of the plurality of corners that defines a radius of curvature that decreases between each of the plurality of corners.
2. The track nut of claim 1 wherein the polygonal perimeter is a square perimeter that defines four corners and wherein the first end defines an at least partially circular perimeter.
3. The track nut of claim 2 wherein each corner defines a radius extending along a direction parallel to the cylindrical axis.
4. The track nut of claim 1 wherein the variable blend portion includes an exact radius.
5. The track nut of claim 1 wherein the radius of curvature varies from 2 to 5 mm.
6. The track nut of claim 5 wherein the radius of curvature varies from 2.5 to 4 mm.
