Engines and gearboxes
Accurate measurement and alignment is critical in engine manufacturing, where tight tolerances and high loads leave little room for error. From initial assembly to final installation, small deviations can lead to vibration, uneven wear, and reduced efficiency over time.
Measuring bearing journals
This is one task where precise alignment is essential during engine manufacturing. When measuring bearing journals with the Easy-Laser® XT950 bore alignment system, the laser transmitter is mounted axially at one end of the engine using magnets. Fine adjustment of the laser beam is easily carried out via the transmitter’s integrated offset hub. The detector unit is then positioned in each bearing journal, and measurement values are recorded in sequence.
The measurement results show the vertical and horizontal position of each bearing journal relative to two selected reference points. Any bearing can be used as a reference, and the reference points can be shifted to calculate the minimum required machining or tooling work.
Other measurement requirements
Engine manufacturers also perform measurements such as flatness of parting surfaces, squareness of cylinder bores, and shaft alignment during drive line assembly.
