Includes 2 magnetic arc-shaped B.A.T. Laser Transmitters, where each B.A.T. Transmitter is also the B.A.T. Target for it’s counterpart. The best option for faster, easier alignments.However there is an error in this single laser measurement that is not always detectable to the human eye. The contributing factors are:
The errors of the single laser systems occur when the laser hits the targets at any distance and the laser beam widens, let’s say 1/8″ and the target line is 1/8th”, thus “spanning” the target line. It is very difficult to visually decipher if the laser line is actually on the target lines or just “bleeding” into or out of the target.
Your system appears to be in alignment, but the sheaves can still be offset and angularly misaligned. This error can only be detected if you reverse the laser and targets and repeat the alignment process, and when this correction move is made, you must then reverse the targets and laser to validate the measurement. Generally another move is required.
This Process may need to be repeated several times, especially on large or temperamental systems. This is very time consuming, costly, and confusing to the technician, also as experience has seen, most technicians do not reverse the laser and targets to validate the alignment, leaving the system in a compromised alignment state.
During my many years as a vibration analyst and reliability expert & have witnessed belt driven machines that are“Bad Actors” which are unreliable and have cronic failures. Misalignment issues like this case is why the B.A.T. Belt Alignment Tool® was invented.
This blower has a base mounted motor on the fan pedestal and it was a cronic “Bad Actor” which frequently tore up belts & showed high vibration readings indicating that there were belt problems. When the alignment was checked with a single laser belt alignment tool it did not show a misalignment condition. However, the blower still mysteryously destroyed belts & other system components. Over 8 years it destroyed 28 sets of Belts (84 Belts), 3 Sets of Bearings & 2 Drive Shafts. When the alignment was finally checked with a B.A.T. Belt Alignment Tool® it showed the “TRUE” severe misalignment. It was so far out of alignment that it required .200” shims on the outboard motor feet for the correction. After shims were installed, Vibration was reduced to acceptable levels, efficiency and reliability were restored. The B.A.T. Belt Alignment Tool® showed the true misalignment and made the correction moves obvious, fast and easy the first time.
