Shaft alignment made simple by SKF
Shaft alignment made simple by SKF
Keyword Metrology
By combining laser diodes and positioning detectors in two measuring units SKF has developed a simple, accurate and very effective method of aligning horizontal shafts in rotating machinery.
Designated Shaft Alignment Tool TMEA1 (see Plate 1), the new device can be used without prior training and is ideal for service, maintenance and quality control departments across a wide array of industries. By perfecting alignment, engineers will be able to improve reliability, prevent vibration in shafting which, in turn, extends bearing and seal life, eliminates shaft fatigue, reduces energy consumption and problems associated with heat generation.

The ready to use TMEA1kit comprises two measuring units consisting of a transmitter and detector, two shaft chain clamping fixtures, an LED calculator and display, a measuring tape and a set of pre-cut machinery shims.
In use, the measuring units are attached to each shaft and the on-screen display provides step by step instructions to guide the operator through the alignment procedure. The machinery can then be correctly positioned using the shim set according to the calculated "real time" values determined by the diode 1mV laser and single axis PSD detectors. Operation of the unit is by just four buttons with a clear LCD display on the 55mm by 77mm screen.
The TMEA1 unit can be used on shafts between 30mm and 500mm diameter and the maximum distance between the measuring units is one metre. Battery driven, the displayed error is better than two per cent and linearity better than one per cent. The unit is operable between 0° and 50°C.
The TMEA1 kit is supplied in sturdy carrying case just 425 mm by 330 mm by 115 mm and weighs just 4.5Kg.
