2. Principle of operation
The TKBA 11 consist of one laser emitting unit that attaches magnetically to
the side of the driving pulley or sprocket and three passive targets that also
attach magnetically for the driven pulley or sprocket. The transmitter unit
emits a laser line that is projected onto the three passive targets ideally and
strategically positioned.
The passive targets have reference lines. The laser line is then visible to
the passive targets for a reading on the different possible misalignment
scenarios, greatly increasing the accuracy and the ease of performing the
alignment.
Depending on the position and orientation of the laser line projected on the
three targets, it is possible to determine the type of misalignment and how
to correct it. Belt alignment is easily performed by adjusting the moveable
machine(s) until the laser line coincides with the reference lines on the
three targets.
