发明名称 Ground Engaging Tool Assembly
摘要 A ground engaging tool system comprising a ground engaging tip. The ground engaging tip includes an interior surface with a coupler pocket having an opening. The interior surface has a base wall and a first and second side wall. The tip defines a first and second coupler face walls having a planar portion and a curved portion. The planar portion is adjacent the base wall, and the curved portion adjacent the opening. The ground engaging tool system includes a coupler movably connected to the ground engaging tip between a nominal position and a maximum rotated pitch position. The coupler includes a mounting nose with a first and second exterior face surface and is within the coupler pocket. Between the nominal position and the maximum rotated pitch position, the curved portion coupler face walls are in non-contacting, spaced relationship with the coupler.

主权项 1. A ground engaging tool system comprising: a ground engaging tip having a coupling portion and a ground engaging portion, the ground engaging portion and the coupling portion extending along a longitudinal axis, the coupling portion including an interior surface defining a coupler pocket having an opening, the interior surface having a base wall, a first side wall and a second side wall in spaced relationship to each other and extending longitudinally from the base wall, and a first coupler face wall and a second coupler face wall in spaced relationship to each other and extending longitudinally from the base wall and extending between the first side wall and the second side wall, wherein the first coupler face wall and the second coupler face wall each has a planar portion and a curved portion, the planar portion being disposed adjacent to the base wall, and the curved portion adjacent the opening of the coupler pocket; a coupler pivotally connected to the ground engaging tip such that the ground engaging tip is movable with respect to the coupler over a range of travel about a retention axis between a nominal position and a maximum rotated pitch position, the coupler including a mounting nose, the mounting nose including a first exterior face surface and a second exterior face surface in opposing relationship to the first exterior face surface, the mounting nose disposed within the coupler pocket such that the first exterior face surface and the second exterior face surface are respectively adjacent the first coupler face wall and the second coupler face wall of the ground engaging tip; and wherein, over the range of travel between the nominal position and the maximum rotated pitch position, the curved portion of both the first coupler face wall and the second coupler face wall are in non-contacting, spaced relationship with the coupler.
