Wear of bucket excavator teeth
QUESTION:Is anyone aware of research into the wear of bucket teeth for
hydraulic excavators or backhoe's.
I am particularly interested in research into the way in which the
original dimensions when new change with time.
I heard once years ago about a mining outfit that used excavators with
urethane elastomer overcoat on the steel teeth. I'm sorry I can't help
you with the source, though
ANSWER: In the excavator buckets the teeth used varies depending on the
applications. Also the teeth material could be a forging or a casting.
Yet again as castings a number of alloys are used. We find quite often
that the end teeth also known as cutters wear out faster than the
centre ones. Also if the bucket is used only as a shovel,the wear is
lesser. It is interesting to study the wear patterns,but it could only
be done in the mines or fields ,lab simulation and studies will not be
a true reflection of the end usage due to the various parameters
involved. Operator's skills also plays a role all factors remaining
same.
