Rotary bearings company SKF has developed a simple battery-operated diagnostic tool for aligning horizontal shafts in rotating machinery.
Using laser techniques to measure misalignment, the TMEA1 tool consists of two parts, a transmitter and a detector. These are attached to the two shafts to be aligned, using a chain-clamping fixture.
Shaft alignment is achieved by using a hand-held display unit which guides the operator through the procedure. Pre-cut shims are used to position the machinery, according to the real-time values on the display.
The equipment suits shafts between 30mm and 500mm diameter. Displayed error is better than 2% and linearity better than 1% over the 0 50 C range.
