Locking nut with a directional coupling mechanism
First Claim
1. A locking nut for installation on a cylinder, wherein the cylinder is comprised of a cylinder engagement surface comprising a threaded cylinder section, the locking nut comprising:
- (a) a nut body having a first nut end, a second nut end, and defining a nut engagement surface extending between the first nut end and the second nut end, wherein the nut engagement surface is engageable with the cylinder engagement surface;
(b) the nut engagement surface comprising a threaded nut section, wherein the threaded nut section is threadably connectable with the threaded cylinder section; and
(c) a directional coupling mechanism associated with the nut body, for locking the nut body with the cylinder in response to relative rotation between the nut body and the cylinder in a locking direction when the locking nut is installed on the cylinder wherein the directional coupling mechanism is comprised of;
(i) a plurality of rolling members spaced around a circumference of the nut engagement surface, wherein the rolling members lock the nut body with the cylinder in response to relative rotation between the nut body and the cylinder in the locking direction when the locking nut is installed on the cylinder, and wherein the rolling members are interposed between the nut engagement surface and the cylinder engagement surface when the locking nut is installed on the cylinder; and
(ii) a plurality of recesses defined in the nut engagement surface and spaced around the circumference of the nut engagement surface, wherein the plurality of rolling members is contained within the plurality of recesses so that the rolling members are spaced around the circumference of the nut engagement surface, wherein the recesses are located adjacent to the second nut end, and wherein the rolling members can be inserted into the recesses from the second nut end and can be removed from the recesses from the second nut end when the nut engagement surface is engaged with the cylinder engagement surface.

Abstract
A locking nut for installation on a cylinder, including a nut body defining a nut engagement surface and a directional coupling mechanism associated with the nut body, for locking the nut body with the cylinder in response to relative rotation between the nut body and the cylinder in a locking direction. The directional coupling mechanism may include a plurality of recesses, a plurality of rolling members contained within the recesses, and a retaining device for retaining the rolling members in the recesses. A method of installing the locking nut on the cylinder, including engaging the nut engagement surface with a cylinder engagement surface, inserting the rolling members in the recesses, threadably connecting the nut body with the cylinder in order to install the locking nut on the cylinder, and connecting the retaining device with the nut body in order to retain the rolling members within the recesses.
