Abstract

A pin assembly for use in a planetary gear, including a pin defining a blind bore therein, the blind bore extending axially from an opening and terminating with an end face, and an annular rib depending inwardly from an inner surface of the blind bore adjacent the opening. A plug includes a stopper portion and a shaft extending therefrom, the stopper portion including a circular base defining an outer perimeter. The outer perimeter of the stopper portion engages the annular rib, thereby maintaining the plug in the blind bore.

Claims (29)

1. A pin assembly for use in a planetary gear, comprising:

a pin defining a blind bore therein, the blind bore extending axially from an opening and terminating with an end face, and an annular rib depending inwardly from an inner surface of the blind bore adjacent the opening; and

a plug including a stopper portion and a shaft extending therefrom, the stopper portion including a circular base defining an outer perimeter,

wherein the outer perimeter of the stopper portion engages the annular rib, thereby maintaining the plug in the blind bore.

2. The pin assembly of claim 1 , wherein the stopper portion further comprises a cone with an outer wall extending from the circular base to an apex.

3. The pin assembly of claim 2 , wherein the cone is hollow.

4. The pin assembly of claim 2 , wherein the shaft extends outwardly from the apex of the cone.

5. The pin assembly of claim 1 , wherein the plug is constructed of a flexible polymer.

6. The pin assembly of claim 1 , wherein the stopper portion of the plug is a cylindrical disk.

7. The pin assembly of claim 1 , wherein a first distance from the annular rib to the end face of the blind bore is less than a second distance from a distal end of the shaft to the circular base of the stopper.

8. The pin assembly of claim 1 , further comprising an inlet bore and a outlet bore, both the inlet bore and the outlet bore extending radially inwardly from an outer cylindrical surface of the pin to the inner surface of the blind bore.

9. The pin assembly of claim 1 , wherein the shaft of the plug is bowed prior to insertion into the blind bore.

10. A pin assembly for use in a planetary gear, comprising:

a pin defining a blind bore therein, the blind bore extending axially from an opening and terminating with an end face, and an annular rib depending inwardly from an inner surface of the blind bore adjacent the opening; and

a plug including a stopper portion, the stopper portion including a circular base defining an outer perimeter,

wherein the outer perimeter of the stopper portion engages the annular rib, thereby maintaining the plug in the blind bore.

11. The pin assembly of claim 10 , wherein the plug further comprises a shaft portion extending therefrom.

12. The pin assembly of claim 11 , wherein a first distance from the annular rib to the end face of the blind bore is less than a second distance from a distal end of the shaft to the circular base of the stopper.

13. The pin assembly of claim 10 , wherein the stopper portion further comprises a cone with an outer wall extending from the circular base to an apex.

14. The pin assembly of claim 10 , wherein the plug is constructed of a flexible polymer.

15. The pin assembly of claim 10 , wherein the stopper portion of the plug is a cylindrical disk.

16. The pin assembly of claim 10 , further comprising an inlet bore and a outlet bore, both the inlet bore and the outlet bore extending radially inwardly from an outer cylindrical surface of the pin to the inner surface of the blind bore.

17. A pin assembly for use in a planetary gear, comprising:

a pin defining a blind bore therein, the blind bore extending axially from an opening and terminating with an end face, and an annular rib depending inwardly from an inner surface of the blind bore adjacent the opening; and

a plug including a stopper portion and a shaft extending therefrom to a distal end, the stopper portion including a circular base defining an outer perimeter,

wherein the distal end of the shaft abuts the end face of the blind bore when the plug is inserted in the blind bore.

18. The pin assembly of claim 17 , wherein the outer perimeter of the stopper portion engages the annular rib, thereby maintaining the plug in the blind bore.

19. The pin assembly of claim 17 , wherein the stopper portion further comprises a cone with an outer wall extending from the circular base to an apex.

20. The pin assembly of claim 17 , wherein the stopper portion of the plug is a cylindrical disk.
