    Abstract: A replaceable wear point of excavating equipment, such as a tooth of an excavator bucket, is mounted on the bucket's nose piece using a conventional fastener arrangement plus an adhesive, preferably epoxy, injected into the tooth pocket to fill a gap between the nose piece and the tooth pocket. For injecting the epoxy, a hole is preferably formed through the tooth to communicate into the bottom of the tooth pocket. The injected epoxy preferably squeezes out of the tooth pocket opening and is smoothed to form an epoxy fillet along the junction of the tooth and the nose piece. The epoxy fills gaps, holds the tooth tight against wiggling on the nose piece, and seals out grit and water, to prevent or reduce interior wear of the tooth pocket and the nose piece, and to prevent or delay the tooth from falling off the nose piece.

    Abstract: A ground engaging tooth assembly for a cutting edge of a ground engaging implement may include an adapter and a ground engaging tip. The adapter may have a forward extending adapter nose having an inverted or reverse keystone-shaped contour, with the ground engaging tip having a nose cavity for receiving the adapter nose and exterior surfaces having complementary shapes to the adapter nose. The adapter nose and an adapter cavity of the tip may also be configured with complimentary surfaces that increase retention between the adapter nose and the tip when downward forces are applied to the tip. In other embodiments, the surfaces of the tip may include reliefs extending inwardly into the body of the tip to reduce weight and facilitate penetration of the tip into work material as wear material wears away from a front edge of the tip.

  • Patent number: 8347530
    Abstract: A tooth assembly including an adapter and a tooth. The adapter has a nose portion with a first predetermined configuration. The tooth is assembled onto the adapter nose portion by relative longitudinal movement. The tooth defines a blind cavity having a second predetermined configuration and opening to a rear of the tooth. The second predetermined configuration defined by the tooth cavity is greater than the first predetermined configuration defined by the adapter nose portion such that a space is provided between the adapter nose portion and the blind cavity when the adapter and tooth are arranged in operable combination relative to each other. A securement member releasably maintains the tooth and the adapter nose portion in operable combination relative to each other. The securement member fills the space defined between the tooth cavity and the adapter nose portion to resist longitudinal movement between the tooth and the adapter nose portion.

  • Publication number: 20120304505
    Abstract: An excavator implement attachment system can include a tooth having a pocket formed therein, an insert received in a recess formed in an adaptor nose and a threaded fastener which releasably secures the tooth on the nose, the fastener having a helical thread formed thereon which is eccentric relative to a fastener body. A tooth can include a pocket with at least one side wall which has an insert-receiving recess and generally planar insert-engaging interface surfaces formed therein, with one interface surface resisting rotation of the tooth about a longitudinal axis in one direction, and another interface surface resisting rotation of the tooth about the longitudinal axis in an opposite direction. An excavator tooth can include a pocket bounded by opposing side walls, with at least one of the side walls having an insert-receiving recess internally formed thereon, whereby the recess receives an insert installed in an adaptor nose.

    Abstract: An excavator tooth assembly comprises a first wear member and a second wear member. The second wear member is releasably mountable on the first wear member. The first wear member has a lock face. The second wear member also has a lock face. The lock face of the first wear member opposes the lock face of the second wear to define a lock passage therebetween when the second wear member is mounted on the first wear member. The excavator tooth assembly includes a lock pin which is adapted to be received in the lock passage to releasably secure the second wear member to the first wear member.

  • Patent number: 8312650
    Abstract: In a wear assembly for securing wear members to excavating equipment, a spool is used with a wedge to hold the wear member in place. The spool is formed with at least one laterally extending arm at its upper end in lieu of an axial arm such as used in a conventional C-shaped spool. In this way, the spool can be easily supported in the assembly as the wedge is installed. The spool does not fall through the opening and no special care is needed to prevent it from falling. The spool also holds itself in place when the wedge is driven into the passage. As a result, installation of the wear assembly is easier and less hazardous. In addition, the lateral support reduces the risk that the spool will suffer spreading.
