Ground engaging tool locking system
A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.
1. A ground engaging tool locking system comprising:
a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis, wherein the pin includes a groove located along an exterior surface of the pin, wherein the groove is configured to receive a biasing element; and
an adapter having an interior passage extending along an axis, wherein the interior passage is configured to receive the pin and the biasing element, wherein at least a portion of the interior passage tapers and narrows in width moving inwardly along the interior passage, such that the interior passage includes a first diameter adjacent an outer surface of the adapter, and a second, smaller diameter axially inwardly of the outer surface;
wherein the adapter includes a protrusion along a side of the adapter, and wherein the first, proximal head region includes a region that is sized and shaped and configured to fit over the protrusion.
2. The ground engaging tool locking system of claim 1 , wherein the interior passage includes an internal groove.
3. The ground engaging tool locking system of claim 2 , wherein the internal groove is disposed axially inwardly of the portion of the interior passage that narrows in width.
4. The ground engaging tool locking system of claim 3 , wherein the interior passage includes a further portion that has a generally constant diameter, wherein the further portion is disposed axially inwardly of the internal groove.
5. The ground engaging tool locking system of claim 2 , further comprising the biasing element, wherein the biasing element is disposed partially in the groove of the pin and partially within the internal groove.
6. The ground engaging tool locking system of claim 1 , wherein the protrusion is a wedge having an inclined surface.
7. The ground engaging tool locking system of claim 6 , wherein when the pin is rotated about the axis, the proximal head region is configured to ride along the inclined surface, so as to axially displace the pin along the axis.
8. A ground engaging tool locking system comprising:
a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis, wherein the pin includes a groove located along an exterior surface of the pin, wherein the pin is configured to receive a biasing element;
an adapter having an interior passage extending along an axis, wherein the interior passage is configured to receive the pin and the biasing element, wherein the interior passage includes a first portion having a first diameter, a second portion having a second diameter, and a third portion having a third diameter, wherein the adapter includes a first interior wall that forms a transition between first portion and the second portion, and a second interior wall that forms a transition between the second portion and the third portion, wherein the second portion is disposed axially between the first portion and the third portion, and wherein the second diameter is larger than both the first diameter and the third diameter; and
the biasing element, wherein the biasing element is disposed partially in the groove of the pin and is pressed against the first interior wall of the adapter.
9. The ground engaging tool locking system of claim 8 , wherein the pin includes a separate internal passage extending through the pin, wherein the separate internal passage is threaded.
10. The ground engaging tool locking system of claim 8 , wherein the adapter includes an inclined surface, wherein when the pin is rotated about the axis, the inclined surface is configured to axially displace the pin.
11. A ground engaging tool locking system comprising:
a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis, wherein the pin includes a groove located along an exterior surface of the pin, wherein the pin is configured to receive a biasing element;
an adapter having an interior passage extending along an axis, wherein the interior passage is configured to receive the pin and the biasing element, wherein the interior passage includes a first portion having a first diameter, a second portion having a second diameter, and an interior wall that forms a transition between first portion and the second portion, wherein the biasing element is configured to expand radially and press against the interior wall to lock the pin in place once the pin has been pressed axially into the interior passage, wherein the adapter includes an inclined surface, and wherein when the pin is rotated about the axis, the inclined surface is configured to axially displace the pin.
12. The ground engaging tool locking system of claim 11 , wherein the pin includes a separate internal passage extending through the pin, wherein the separate internal passage is threaded.
13. The ground engaging tool locking system of claim 11 , further comprising the biasing element, wherein the biasing element is disposed partially in the groove of the pin and is pressed against the interior wall of the adapter.
14. A ground engaging tool locking system comprising:
a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis, wherein the pin includes a groove located along an exterior surface of the pin, wherein the pin is configured to receive a biasing element;
an adapter having an interior passage extending along an axis, wherein the interior passage is configured to receive the pin and the biasing element, wherein the interior passage includes a first portion having a first diameter, a second portion having a second diameter, and a third portion having a third diameter, wherein the adapter includes a first interior wall that forms a transition between first portion and the second portion, and a second interior wall that forms a transition between the second portion and the third portion, wherein the second portion is disposed axially between the first portion and the third portion, and wherein the second diameter is larger than both the first diameter and the third diameter;
wherein the adapter includes an inclined surface, wherein when the pin is rotated about the axis, the inclined surface is configured to axially displace the pin.
