Abstract

An installation tool is disclosed. The installation tool includes a mandrel. The mandrel includes a tapered body having a smaller end and a larger end. The smaller end of the mandrel is configured to receive a retention ring thereon. Further, the larger end of the mandrel includes a bore. The bore is configured to receive a portion of a spool therein. The installation tool also includes a gripping member. The gripping member includes an elongate body. The gripping member also includes a plurality of fingers coupled to a first end of the elongate body and extending axially therefrom. The plurality of fingers is configured to slide the retention ring over the tapered body of the mandrel during an installation of the retention ring on the spool. The gripping member further includes an ejection mechanism. The ejection mechanism is configured to disengage the mandrel from the gripping member.

Claims

1. An installation tool comprising:

a mandrel including a tapered body having a smaller end and a larger end, wherein the smaller end is configured to receive a retention ring thereon, and wherein the larger end includes a bore, the bore configured to receive a portion of a spool therein; and

a gripping member comprising;

an elongate body defining a central axis;

a plurality of fingers coupled to a first end of the elongate body, the plurality of fingers extending axially from the elongate body, wherein the plurality of fingers are configured to slide the retention ring over the tapered body of the mandrel during an installation of the retention ring on the spool; and

an ejection mechanism provided on the elongate body, the ejection mechanism configured to disengage the mandrel from the gripping member.

2. The installation tool of claim 1, wherein the ejection mechanism includes a button provided at a second end of the elongate body.

3. The installation tool of claim 1, wherein the ejection mechanism includes a rod slidably provided within the elongate body, the rod configured to push the mandrel out of the plurality of fingers of the gripping member.

4. The installation tool of claim 1, wherein the ejection mechanism includes a spring provided at least partially along a length of the rod.

5. The installation tool of claim 1, wherein the plurality of fingers are threadably coupled to the elongate body.

6. The installation tool of claim 1, wherein a diameter of the bore is sized based on a diameter of the spool.

7. The installation tool of claim 1, wherein a depth of the bore is such that the mandrel is positioned in front of a groove provided on the spool when the mandrel is coupled to the spool.

8. The installation tool of claim 1, wherein an inner surface of each of the plurality of fingers is shaped to cooperate with the tapered body of the mandrel.

9. The installation tool of claim 1, wherein an outer surface of each of the plurality of fingers is planar.

10. The installation tool of claim 1, wherein each of the plurality of fingers is made of any one of a metal and an alloy.

11. The installation tool of claim 1, wherein each of the plurality of fingers are circumferentially spaced apart from one another.

12. The installation tool of claim 1, wherein the elongate body of the gripping member has a cylindrical configuration.

13. A method for installing a retention ring on a spool, the method comprising:

receiving the spool into a bore provided on a larger end of a tapered mandrel;

placing the retention ring on a smaller end of the tapered mandrel;

aligning a gripping member with the tapered mandrel;

contacting a plurality of fingers of the gripping member with the retention ring and the tapered mandrel;

sliding the retention ring over the tapered mandrel;

positioning the retention ring on the spool;

engaging the tapered mandrel within the plurality of fingers of the gripping member;

decoupling the tapered mandrel and the gripping member from the spool; and

disengaging the tapered mandrel from the gripping member.
