Abstract:
A cutting element includes a sleeve, a rotatable cutting element, and at least one retaining ring. The sleeve has a first inner diameter and a second inner diameter, wherein the second inner diameter is larger than the first inner diameter and located at a lower axial position than the first inner diameter. The rotatable cutting element has an axis of rotation extending therethrough, a cutting face, a body extending axially downward from the cutting face, wherein the body has a shaft that is disposed within the sleeve, and a circumferential groove formed around an outer surface of the shaft. The at least one retaining ring is disposed in the circumferential groove and extends at least around the entire circumference of the shaft, wherein the at least one retaining ring protrudes from the circumferential groove, thereby retaining the rotatable cutting element within the sleeve.

Claim (Index 15):
A rotatable element assembly for use in a drill bit, comprising:\n a sleeve including a first portion having at least a first inner diameter, and a second portion having at least a second inner diameter greater than the first inner diameter; a rotatable element having an axis of rotation extending therethrough, the rotatable element including a face and a body extending axially away from the face, at least a portion of the body being within the sleeve, and the body including at least one groove in an outer surface thereof, and which at least one groove is at least partially within the second portion of the sleeve; at least one retainer contained fully within the at least one groove of the rotatable element and the second portion of the sleeve, the at least one retainer extending radially outward of the outer surface of the body and thereby retaining the rotatable element within the sleeve; and a spring axially compressible by movement of the rotatable element relative to the sleeve, the spring being positioned in the at least one groove and within the second portion of the sleeve.
