cross dial alignment Flashcards
With which dial alignment procedure offs shaft end float a potential source of error?
Rim and face alignment
When mounting the A dial and B dial into a machine to be aligned, mange sure?
The B dial reads on the rim of the moveable machine
When taking readings for vertical where is A and B zeroed at?
A is zeroed at the top and B at the bottom
Coupling run out is a measure of?
Eccentricity
Before starting a vertical portion of a cross dial alignment a rough alignment must be completed.horizontal readings taken by both dials should measure less than?
10 thou
What I’d the maximum allowable soft foot for alignment
2 thou
What is the purpose of taking a sweep reading?
To ensure proper installation off dials
What is the reverse dial procedure?
Both dials are zeroed at the same position when taking readings.
What does the X in cross dial formula represents?
Distance between A and B dials
How it’s dial bar sag applied to the vertical dial readings when the A dial it’s zeroed at 12:00 o’clock and B dial is zeroed at the 6:00 o’clock?
Subtract from B dial at 12 o’clock and add to A dial at 6 o’clock
The cross dial alignment procedure uses?
Two dials reading off opposite rims
The best set of dial brackets would be?
Free of sag by design.
Rim run out readings are taken with the dial button reading on?
The rotated rim
When checking for coupling rim run out the high spot on the rim causes the dial to?
Move to a positive value.
Why is it important to use the whole graph scale when constructing a cross dial graphical solution?
The constructed graph is more accurate
