RELIABILITY CONCEPTS

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 targets in the center target line of the opposing targets and when on all three center lines the system is said to be in alignment... 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 to 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..
