Lubricating fluid damped anti-rotational systems
A lubricating fluid damped anti-rotational system is provided comprising a pawl carrier having an axis of rotation and a radial aperture, a pawl pivotably mounted to the pawl carrier on a pivot joint, the pawl having a contact portion and a counterweight portion, a lubricating fluid jet configured to propel a lubricating fluid through the radial aperture toward the contact portion.
1. A method, comprising:
rotating a pawl carrier about an axis of rotation, the pawl carrier coupled to a shaft via a pawl nut connected to the shaft and to the pawl carrier, the pawl nut and the shaft configured to rotate about the axis of rotation,
the pawl carrier comprising
a first radial aperture and
a pawl pivotably mounted to the pawl carrier on a pivot joint, the pawl having a contact portion and a counterweight portion,
wherein the first radial aperture is disposed within the pawl carrier and configured to distribute a lubricating fluid jet radially outward toward the contact portion of the pawl, and
the pawl nut disposed radially inward of the pawl carrier and including a second radial aperture in fluid communication with the first radial aperture; and
directing a lubricating fluid through the first radial aperture and the second radial aperture toward the contact portion.
2. The method of claim 1 , wherein the directing is continuous.
3. The method of claim 1 , wherein a stop pin is axially disposed in the pawl carrier and configured to contact the contact portion of the pawl in response to radially inward movement of the pawl.
4. The method of claim 3 , wherein the first radial aperture is positioned radially inward of the stop pin.
5. The method of claim 1 , wherein a torsion spring is coupled to the pivot joint.
6. The method of claim 5 , wherein the torsion spring is coupled to the pivot joint to cause the contact portion to rotate radially outward relative to the pawl carrier.
