Alignment is the most important way to increase life span of industrial equipment.
Alignment can be done on any rotating equipment such as: fans, fans to motor, kilns, etc. Alignment allows mechanical machinery to run smoothly. Incorrect alignment occurs when the centerlines of the motor and the driven equipment shafts are not in line with each other. Misalignment produces excessive vibration, noise, coupling and bearing temperature increases, and premature bearing or coupling failure.
In practice, proper alignment is difficult to achieve without using alignment equipment such as dial indicators or laser alignment tools to check and correct for misalignment. The proper shaft alignment procedure is to secure the driven equipment first, and then install the coupling to the equipment. When doing a kiln alignment it is critical to know tolerances and possible mismatches with equipment. For example not everything will be perfect. Kiln piers, kiln ovality, kiln bearings, tire wear, tire pads all come into play. Alignment of gears is essential to transfer power without excessive wear.
