Snatch ring pulley

1. A snatch ring pulley assembly comprising:

a pulley wheel body having a first outer wheel portion, a second outer wheel portion parallel to the first outer wheel portion, and a rope saddle portion defined between the first outer wheel portion and the second outer wheel portion, and defining a center aperture extending through the first outer wheel portion and the second outer wheel portion; and

a first deformable retention feature affixed to the first outer wheel portion of the pulley wheel body, wherein the first deformable retention feature extends toward the second outer wheel portion, uniformly around and adjacent to an outer circumference of the first outer wheel portion, and between and perpendicular to both the first outer wheel portion and the second outer wheel portion, wherein the first deformable retention feature comprises a plurality of resilient fingers spaced apart from each other,

wherein the rope saddle portion does not include any deformable retention features.

2. The snatch ring pulley assembly of claim 1 further comprising:

a second deformable retention feature affixed to the second outer wheel portion, wherein the second deformable retention feature extends toward the first outer wheel portion, uniformly around and adjacent to an outer circumference of the second outer wheel portion, and between and perpendicular to both the first outer wheel portion and the second outer wheel portion.

3. The snatch ring pulley assembly of claim 2 , wherein the first deformable retention feature and the second deformable retention feature both comprise respective pluralities of resilient fingers spaced apart from each other.

4. The snatch ring pulley assembly of claim 3 , wherein each of the resilient fingers of the first deformable retention feature are aligned with respective opposing resilient fingers of the second deformable retention feature.

5. The snatch ring pulley assembly of claim 3 , wherein

the pulley wheel body defines a plurality of through holes in the first outer wheel portion and a plurality of through holes in the second outer wheel portion;

the resilient fingers of the first deformable retention feature seat within the through holes in the first outer wheel portion; and

the resilient fingers of the second deformable retention feature seat within the through holes in the second outer wheel portion.

6. The snatch ring pulley assembly of claim 1 , wherein the deformable retention feature is in the form of a bristle ring including a plurality of flexible bristles extending from a base ring.

7. The snatch ring pulley assembly of claim 6 , wherein

the pulley wheel body defines an annular groove in the first outer wheel portion;

the base ring comprises a coupling feature that is configured to be retained within the annular groove; and

the coupling feature of the bristle ring is retained in the annular groove.

8. The snatch ring pulley assembly of claim 1 , wherein a surface defining the center aperture is coated with a material having a low coefficient of friction.

9. A snatch ring pulley assembly comprising:

a pulley wheel body including:

a first outer wheel portion including a plurality of through holes defined therein,

a second outer wheel portion parallel to the first outer wheel portion and including a plurality of through holes defined therein, and

a rope saddle portion defined between the first outer wheel portion and the second outer wheel portion; and

a first plurality of resilient fingers seated within the plurality of through holes in the first outer wheel portion and a second plurality of resilient fingers seated within the plurality of through holes in the second outer wheel portion,

wherein the first plurality of resilient fingers extend from the first outer wheel portion toward the second outer wheel portion, and

wherein the second plurality of resilient fingers extend from the second outer wheel portion toward the first outer wheel portion,

wherein the rope saddle portion does not include any resilient fingers.

10. The snatch ring pulley assembly of claim 9 , wherein the rope saddle portion of the pulley wheel body defines a plurality of rope traction features.

11. The snatch ring pulley assembly of claim 9 , wherein the pulley wheel body defines a center aperture bounded by a surface and the surface is coated with a material having a low coefficient of friction.
