Laser Alignment Flashcards
what are the three basic types of laser alignment systems?
- single reflected beam with single detector
- dual beam with dual detectors
- single beam with dual detectors
What is dynamic interruption and which systems allow for it?
dynamic interruption is where the beam falls outside the range of the detector while you rotate the coupling. the dynamic interruption allows you to readjust the beam back to within the range of the detector without starting over.
- single reflected beam single detector
- single beam dual detectors
What are the key components to a laser detector system?
- Transmitter or detector unit
- Reflector
- Bracket
What part of the laser alignment goes on the shaft of the stationary machine?
Laser/Detector
What part of the laser alignment goes on the machine to be moved?
Prism reflector
Some units need to be rotated together, some units allow you to take readings at any three of the eight positions located 45 d apart, and on other units you only need to do a ________ degree sweep to get all the information needed for the machine to do its calculations.
60-70 degree sweep
New laser alignment tools incorporate what features?
- built in inclinometer
- vibration monitoring
- backlash detection
- Bore alignment
- Thermal growth measurement
What class laser are used in laser alignment tools?
class 2 (visible beam) you can damage your eyes by staring into the beam
What can cause beam distortion in laser alignment systems?
Extreme heat or steam
Most micro processors are rated to _____ degrees C
Above 0 degrees C
What are typical dimensions you must enter into the system?
- Laser to prism
- Laser to coupling center
- Coupling diameter
- RPM or default
- Laser to front foot of motor
- Front foot of motor to back foot of motor
Can you check for softfoot with laser alignment?
Yes
why would you use laser alignment for a bore instead of string alignment?
much faster
The laser beam is emitted from the ?
Laser/detector mounted on the stationary machine
