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, the proximal head region including a proximal end and a distal end, the proximal head region further including a tooth engagement surface adjacent the proximal end and an adapter engagement surface positioned between the tooth engagement surface and the distal end of the proximal head region;
- a groove positioned along an exterior of the pin;
- a ramped surface disposed on the 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 for releasably securing a tooth to an adapter, the 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 first ramped surface extending in a helical manner at least partially about the axis, the first ramped portion configured to be positioned on an internal portion of the adapter;
- and
- a second ramped surface disposed on a distal end of the proximal head region, wherein the second ramped surface has a width as measured radially along a direction orthogonal to the axis and extending in a helical manner at least partially about the axis, wherein the second ramped surface faces away from the proximal head region, the second ramped surface engaging the first ramped surface on the adapter in a complementary manner, wherein the second ramped surface is sized and shaped and oriented such that when the pin is positioned within the adapter and rotated about the axis, the second ramped surface engages the corresponding first ramped surface on the adapter and generates an axial movement of the pin along the axis and away from the adapter.
