Secure Mounting of Excavation Equipment Teeth

摘要

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.

主权项

1. A combination for mounting a replaceable ground-engaging tooth of a ground-engaging tool of a powered excavating machine, comprising:
a nose piece connected to said ground-engaging tool; a replaceable ground-engaging tooth that has a tooth pocket therein configured and dimensioned to fit on said nose piece, and that is mounted on said nose piece fitted into said tooth pocket with a gap remaining between said nose piece and said tooth in said tooth pocket; a fastening arrangement that mechanically fastens said tooth onto said nose piece; and an adhesive disposed in said gap and bonding said nose piece to said tooth in said tooth pocket.
