Abstract
An excavating system for use in ground-engaging applications. The excavating system may include a wear member having a top leg, a bottom leg, and a bearing face connecting the legs. The excavating system may also include a lip, which may include a top inset surface. The top inset surface may have an upper bearing surface shaped to bear against an inner surface of the top leg of the shroud. The top inset surface may also have a forward bearing surface extending between the upper bearing surface and a lower surface formed on the downwardly facing surface. The forward bearing surface may face upwardly and forwardly at a non-vertical angle.
Claims23
An excavating system, comprising:
- a wear member having a leading end and a trailing end, the wear member comprising a receiving end having a top leg having an inner surface, a bottom leg having an inner surface, and a bearing face connecting the top leg and the bottom leg;
- and
- a lip having a leading end, a trailing end, an upwardly facing surface, and a downwardly facing surface, the lip comprising:
- a top inset surface formed in the upwardly facing surface, the top inset surface having:
- an upper bearing surface shaped to bear against the inner surface of the top leg;
- and
- a forward flat bearing surface extending between the upper bearing surface and a lower surface formed on the downwardly facing surface and shaped to bear against the bearing face of the wear member, the forward flat bearing surface facing upwardly and forwardly at a non-vertical angle.
An excavating system, comprising:
- a wear member having a leading end and a trailing end, the wear member comprising a receiving end having a top leg having an inner surface, a bottom leg having an inner surface, and a bearing face connecting the top leg and the bottom leg;
- and
- a lip having a leading end, a trailing end, an upwardly facing surface, and a downwardly facing surface, the lip comprising:
- a top inset surface formed in the upwardly facing surface, the top inset surface having:
- an upper bearing surface shaped to bear against the inner surface of the top leg;
- and
- a forward flat bearing surface extending between the upper bearing surface and a lower surface formed on the downwardly facing surface, the forward flat bearing surface facing upwardly and forwardly at a non-vertical angle;
- a top surface extending between the trailing end and the top inset surface;
- a nose projecting from a leading end of the lip;
- an intermediate surface disposed between the top surface and the nose, the intermediate surface sized and shaped to support a second wear member and having an elevation lower than the top surface;
- and,
- a wear member protector projecting from the upwardly facing surface, the wear member protector connecting the intermediate surface and the top surface, the wear member protector being disposed in a position to protect a trailing end of the second wear member from abrasive flow of materials being poured from a bucket.
An excavating system, comprising:
- an upwardly facing surface spanning between two lateral sides, the upwardly facing surface having:
- a top surface elevated with respect to other parts of the upwardly facing surface, and;
- a top inset surface sunken with respect to the top surface, the top inset surface having:
- a forward flat bearing surface angled outward at a non-vertical angle and shaped to bear against a bearing face of a wear member;
- and,
- an upper bearing surface shaped to bear against a top leg of the wear member;
- a downwardly facing surface spanning between the two lateral sides, the downwardly facing surface having:
- a bottom surface elevated with respect to other parts of the downwardly facing surface.
A method of attaching a wear member to a lip, comprising:
- providing the lip, the lip comprising:
- an upwardly facing surface spanning between two lateral sides and having:
- a top surface elevated with respect to other parts of the upwardly facing surface, and
- a top inset surface sunken with respect to the top surface, the top inset surface having:
- an upper bearing surface shaped to bear against a top leg of the wear member;
- and,
- a forward flat bearing surface angled at a non-vertical angle outward and shaped to bear against a bearing face of the wear member;
- and,
- a downwardly facing surface opposing the upwardly facing surface, the downwardly facing surface having a bottom surface elevated with respect to other parts of the downwardly facing surface;
- and
- locating the wear member about the forward flat bearing surface so that the top leg of the wear member is disposed in the top inset surface.
An excavating system, comprising:
- a lip for supporting a wear member, comprising:
- a nose projecting from a leading end of the lip;
- an upwardly facing surface, comprising:
- a top surface;
- an intermediate surface disposed between the top surface and the nose, the intermediate surface sized and shaped to support the wear member and having an elevation lower than the top surface;
- and
- a wear member protector projecting from the upwardly facing surface, the wear member protector connecting the intermediate surface and the top surface, the wear member protector being shaped and positioned to protect a trailing end of the wear member from abrasive flow of materials being poured from a bucket.
