ASI is proud to offer the Hamar Stealth Series Shaft Systems and the B.A.T. Belt Alignment Tool. The U.S. made, user friendly Stealth Series has industry leading accuracy and repeatability. The B.A.T. Belt Alignment Tool sports high accuracy and 75% faster alignments. The B.A.T. Laser Belt Alignment Tool System is the latest innovation in laser belt alignment systems. Utilizing the GlowLine green laser technology, the Dual-Laser Crossfiring B.A.T. XF was developed to alleviate typical shaft and pulley issues and errors that occur with traditional alignment tools. The B.A.T. eliminates the guess work and increases efficiency saving time and money.
How the B.A.T. solves typical laser alignment tool errors in three steps
1 Single laser belt alignment system design
Single laser belt alignment systems are based on a straight-line measurement that hits two or three targets on a centerline. The targets are placed on the radius of the pulley and a line laser emits from the laser tool. This fan shaped line beam strikes the center lines of the opposing targets, when the laser is on all three center lines, the system is said to be in alignment.
2 Single laser belt alignment
However, there is an error in this single laser measurement that is not always detectable to the human eye. The contributing factors are as follows:
- Size of the pulleys
- Distance between the laser and the targets
- Width of the laser beam
- Linear size of the target
- Type of target, straight or round
- Enviromental conditions
3 How errors are developed
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 in. and the target line is 1/8th in., thus “spanning” the target line. It is 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.
