Rim and face alignment COPY Flashcards
What are 2 types of misalignment
offset(parallel)
angular
what are 3 basic types of coupling for alignment
rigid
flexible
special purpose
coupling that provides a fixed union, therefore you must accurately align for smooth operation
rigid
coupling that is the most common and allows for minor misalignment
flexible
coupling that is completely unique in that some require accurate alignment and others require a set amount of misalignment
special purpose
what are 4 consequences of shaft misalignment
seal damage
increased bearing load
vibration
downtime
the condition where piping fastened to a piece of equipment stresses the housing
pipe strain
the situation where weight distribution is not equal on all supports
soft foot
what are the 3 cases of soft foot
parallel
angular heel
angular toe
the situation when the shaft or coupling is not concentric to its axis
runout
the situation when a shaft moves axially
end float
measurement of how gravity affects dial reading
dial bar sag
to measure dial bar sag, the dial needs to be placed on a
mandrel
to validate a setup by rotating both dials 360 degrees
sweep reading
tir stands for
total indicated reading
