Description
Technical field
The utility model belongs to a kind of excavator automobile fitting field, is specifically related to the Tooth structure of a kind of engineering machinery.
Background technology
Current bucket tooth all uses the alligator of band jump ring to couple between toothholder and tooth overlap, this connecting mode requires there is certain interval between toothholder and tooth set, and during to ensure dress pin, pilot hole has the surplus of centering, without gap, assembling the most difficult, processing and fabricating will reach suitable precision.Under the effect of impulsive force, produce impact and friction between toothholder and tooth set, produce high temperature, making the hardness of material and toughness reduce, cause crown quickly to wear and tear, toothholder is hit fracture, fatigue failure is the most easily produced additionally, due to impact repeatedly, alligator and jump ring.
Utility model content
(1) to solve the technical problem that
The technical problems to be solved in the utility model is to provide a kind of installation and consolidates, the bucket tooth of good impact resistant effect.
(2) technical scheme
For solving above-mentioned technical problem, the utility model be the technical scheme is that the Tooth structure of a kind of engineering machinery, including bucket tooth seat, bucket tooth body and bucket tooth pin assemblies；Described bucket tooth pin assemblies includes the first bearing pin, the second bearing pin and spring；Described bucket tooth seat and bucket tooth body are provided with a coaxial axis hole, and one end of described first bearing pin is provided with this inserted link, and one end of described second bearing pin is provided with jack；Described bucket tooth seat is plugged on bucket tooth, and this is the most internal, and described first bearing pin and the second bearing pin make bucket tooth body be connected with bucket tooth seat in being plugged on axis hole, and described inserted link and spring are coaxially plugged in jack, and the two ends of spring respectively with inserted link and jack contact.
In the Tooth structure of above-mentioned engineering machinery, the periphery of described first bearing pin and the second bearing pin is provided with the protruding block that several annulars are uniform, and described protruding block contacts with the axis hole of bucket tooth seat.
In the Tooth structure of above-mentioned engineering machinery, the periphery of described first bearing pin and the second bearing pin is provided with the groove that several annulars are uniform, and described protruding block is arranged in groove.
In the Tooth structure of above-mentioned engineering machinery, described protruding block has 4.
