Abstract
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.
Claims20
A ground engaging tool locking system comprising:
- a pin having a proximal head region and a distal end region that extends from the proximal head region along an axis, wherein the proximal head region is radially larger than the distal end region;
- a groove positioned along an exterior of the pin;
- a ramped surface disposed along a distal end of the proximal head region, wherein the ramped surface has a width as measured radially along a direction orthogonal to the axis, wherein the ramped surface faces away from the proximal head region, wherein the ramped surface is sized and shaped and oriented such that when the pin is positioned within an adapter and rotated about the axis, the ramped surface is configured to engage a corresponding ramped surface on the adapter and generate an axial movement of the pin along the axis and away from the adapter.
A ground engaging tool locking system comprising:
- an adapter having an interior passage extending along an axis, and a ramped surface disposed within the interior passage, wherein the ramped surface has a width as measured radially along a direction orthogonal to the axis, wherein the ramped surface faces away from the adapter, wherein the ramped surface is sized and shaped and oriented such that when a pin is positioned within the adapter and rotated about the axis, the ramped surface is configured to engage a corresponding ramped surface on the pin and generate an axial movement of the pin along the axis and away from the adapter.
A ground engaging tool locking system comprising:
- a pin having a proximal head region and a distal end region that extends from the proximal head region along a first axis, and a first ramped surface disposed along a distal end of the proximal head region, wherein the first ramped surface faces away from the proximal head region;
- and
- an adapter having an interior passage extending along a second axis, and a second ramped surface disposed within the interior passage, wherein the second ramped surface is sized and shaped and oriented such that when the pin is positioned within the adapter the first axis is co-axial with the second axis, and when the pin rotated about the first axis, the second ramped surface is configured to engage the first ramped surface and generate an axial movement of the pin along the second axis and in a direction away from the adapter,
- wherein the pin and the adapter are sized and shaped such that the pin is configured to be pushed axially into the adapter and to engage the second ramped surface on the adapter without rotation about the first axis.
