The D450 Shaft Alignment System

The system consists of two small measuring detectors, a hand-held display unit, cables and mounting brackets.

Each of the rugged anodized aluminum Position Sensing Detectors (PSD) has a laser beam and a beam detector. The detector is protected by a sliding bulls-eye cover when not in use. By using the dual (two) beams and the closed target cover you can perform a rough alignment. This is a very useful feature, especially when aligning a long shaft. They also have built-in sprit level vials that can be levelled in both the horizontal and vertical planes. This is an excellent feature when performing an open coupling alignment or when only one shaft can be moved.

Programs and Functions of the D450

Soft Foot - With this program you can check so that the machine is resting on all feet. Shows which foot should be corrected (if necessary).

Thermal Growth Compensation - Compensates for difference in thermal growth between machines. This is a sub- program in the machine train program.

Tolerance Check - Checks the offset and angle values towards selected tolerance. Shows graphically when the alignment is within tolerance. Sub-function.

Measurement Value Filter - Advanced electronic filter function for accurate measurement results, even in bad measuring conditions like air turbulence and vibration. Sub-function.

To operate

You will be asked to input the tape measured distances from between the detectors, and to the centre of the coupling, as well as the front and back feet of the machine you choose to move.

You turn the detectors (Shafts) and record the values at the 9, 12 and 3 o'clock positions when prompted by the display unit.

The misalignment results and corrections are now displayed live time on the screen. Horizontal and vertical positions for the movable machine are shown both digitally and graphically with "live" values.

It couldn't be easier.

You measure misalignment at the coupling and make the necessary corrections at the feet.

Vertical plane shown at the top of the screen shows only two feet. You need to lift or lower the machine to make corrections.

Horizontal plane shown at the bottom of the screen shows all four feet (looking down). You need to move the machine back and forth to make corrections.

The Measurement Results

This shows the amount of Offset in the vertical plane. Measured at the coupling. This is the amount of Angular error. To correct the measured misalignment, you need to adjust the feet. In this case, you would add 21 mils or thou to both of the front feet and 33 thou to both back feet. This is the amount of Offset and Angular misalignment measured in the horizontal plane. To correct the horizontal misalignment, you need to move the machine by the amount shown. Notice that the feet are black. This indicates that it is reading live in the horizontal plane. To have it read live in the vertical plane, you simply turn the heads to the twelve o'clock position.

After you have made the corrections, the screen will indicate whether you are within tolerance (within spec) by showing one half of the coupling black.
