Abstract
One illustrative embodiment of the present disclosure may include a snatch ring pulley assembly including a pulley wheel body and a deformable retention feature affixed to the pulley wheel body. The pulley wheel body includes a rope saddle portion, a first outer wheel portion, and a second outer wheel portion substantially parallel to the first outer wheel portion. The deformable retention feature is affixed to the first outer wheel portion and extends toward the second outer wheel portion. The deformable retention feature extends uniformly around a circumference of the first outer wheel portion and extends substantially perpendicular to the first outer wheel portion.

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.
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.
