Retention device

A retention device, comprising:

• a collet nut configured to be inserted in a cylinder rod and to engage a threaded rod inserted in the cylinder rod,
• wherein the collet nut is configured to transition between a compressed state to engage the threaded rod and an expanded state to disengage from the threaded rod;
• and a retainer ring configured to retain the threaded rod in the cylinder rod,
• wherein a first portion, of an outer surface of the retainer ring, is a threaded surface and is adjacent to a bottom surface of the retainer ring,
• wherein a second portion, of the outer surface of the retainer ring, is configured to be torqued to cause the first portion to be threaded onto the cylinder rod and cause the bottom surface of the retainer ring to contact the collet nut and retain the collet nut in the cylinder rod,
• wherein the bottom surface of the retainer ring is configured to cause the collet nut to transition from the expanded state to the compressed state as the bottom surface of the retainer ring contacts a top surface of the collet nut,
• wherein the collet nut comprises a pair of segments and a transition element between the pair of segments,
• wherein the transition element includes an elastomeric material, and
• wherein a bottom surface of the collet nut comprises a tapered surface.

A retention system, comprising:

• a collet nut configured to be inserted in a hydraulic cylinder rod and to engage a rod inserted in the hydraulic cylinder rod;
• and
• a retention component configured to retain the rod in the hydraulic cylinder rod,
• wherein the retention component comprises a first surface and a second surface,
• wherein a portion, of the first surface, is a threaded surface and is adjacent to the second surface,
• wherein the portion, of the first surface, is configured to be threaded onto the hydraulic cylinder rod to cause the second surface to retain the collet nut in the hydraulic cylinder rod,
• wherein the second surface is configured to exert a force on a top surface of the collet nut to cause an inner surface, of the collet nut, to engage the rod,
• wherein the collet nut comprises a pair of segments and a transition element between the pair of segments, wherein the transition element includes an elastomeric material, and
• wherein a bottom surface of the collet nut comprises a tapered surface.
