Abstract

A gear has a central ring positioned about an axis, opposing tabs that extend from a first axial side of the central ring, and a shouldered ring that extends from a second axial side of the central ring, the shouldered ring having a lip that extends radially inward toward the axis.

First claim

1 . A gear comprising:
a central ring positioned about an axis; opposing tabs that extend from a first axial side of the central ring; a shouldered ring that extends from a second axial side of the central ring, the shouldered ring having a lip that extends radially inward toward the axis.

2 . The gear of claim 1 , further comprising a plurality of teeth circumferentially disposed about an outer radial surface of the central ring.

3 . The gear of claim 1 , wherein a radially outward facing surface an opposing tab of the plurality of opposing tabs is arced.

4 . The gear of claim 1 , wherein a radially inward facing surface an opposing tab of the plurality of opposing tabs is flat.

5 . The gear of claim 1 , wherein an outer diameter between radially outward facing surfaces of the central ring is approximately 1.513 in. (3.843 cm).

6 . The gear of claim 1 , wherein an inner diameter between radially inward facing surfaces of the central ring is approximately 1.3254 in. (3.366 cm).

7 . The gear of claim 1 , wherein the shouldered ring extends axially from the central ring for a distance of approximately 0.84 in. (2.133 cm).

8 . A method of replacing gears, the method comprising:
removing a first gear from a shaft; placing a second gear on the shaft, the second gear comprising:
a central ring positioned about an axis;
opposing tabs that extend from a first axial side of the central ring;
a shouldered ring that extends from a second axial side of the central ring, the shouldered ring having a lip that extends radially inward toward the axis.

9 . The method of claim 8 , further comprising a plurality of teeth circumferentially disposed about an outer radial surface of the central ring.

10 . The method of claim 8 , wherein a radially outward facing surface an opposing tab of the plurality of opposing tabs is arced.

11 . The method of claim 8 , wherein a radially inward facing surface an opposing tab of the plurality of opposing tabs is flat.

12 . The method of claim 8 , wherein an outer diameter between radially outward facing surfaces of the central ring is approximately 1.513 in. (3.843 cm).

13 . The method of claim 8 , wherein an inner diameter between radially inward facing surfaces of the central ring is approximately 1.3254 in. (3.366 cm).

14 . The method of claim 8 , wherein the shouldered ring extends axially from the central ring for a distance of approximately 0.84 in. (2.133 cm).

15 . A method of replacing gears, the method comprising:
removing a first gear from a protruding ring on a shaft; placing a second gear on the protruding ring of the shaft, the second gear comprising:
a central ring positioned about an axis;
opposing tabs that extend from a first axial side of the central ring;
a shouldered ring that extends from a second axial side of the central ring, the shouldered ring having a lip that extends radially inward toward the axis.

16 . The method of claim 15 , further comprising a plurality of teeth circumferentially disposed about an outer radial surface of the central ring.

17 . The method of claim 15 , wherein a radially outward facing surface an opposing tab of the plurality of opposing tabs is arced.

18 . The method of claim 15 , wherein a radially inward facing surface an opposing tab of the plurality of opposing tabs is flat.

19 . The method of claim 15 , wherein an outer diameter between radially outward facing surfaces of the central ring is approximately 1.513 in. (3.843 cm).

20 . The method of claim 15 , wherein an inner diameter between radially inward facing surfaces of the central ring is approximately 1.3254 in. (3.366 cm).
