Precise and cost-effective alignment of shafts

Precise and cost-effective alignment of shafts

If the shafts in pumps, compressors or gearboxes are not aligned with each other, the result is higher energy consumption and increased machine wear, which can lead to unplanned downtime. Based on the innovative single laser technology, Schaeffler is now bringing the LASER-EQUILIGN2 alignment tool onto the market, describing it as an innovative system for aligning rotating shafts – for the highest levels of machine performance and availability as well as lower operating costs.

The misalignment of shafts is a big problem for the operation of all types of machines. The temperature in couplings, bearings, grease, and motors increases and the machine or vehicle consumes more energy. Ultimately, the additional friction leads to significantly increased wear, possibly even causing shaft fractures and the total failure of systems and machines. 

The LASER-EQUILIGN2 from Schaeffler enables the precise alignment of shafts and a significant reduction in work for maintenance technicians. This alignment tool can be deployed quickly and precisely due to its single laser technology. The non-verbal user interface with 8in TFT display and capacitive touchscreen (can be operated wearing suitable gloves) enables intuitive, user-friendly operation. The four-point measurement permits very high measurement accuracy.

In contrast to the conventional double laser technology in which two laser/sensor units must be aligned with each other, only one laser/sensor unit and a reflector are used in single laser technology. The single laser is simply aligned with the reflector. Schaeffler says this increases the usability and provides maintenance technicians with precise measurement results.   

The LASER-EQUILIGN2 is described not only as cost-effective but also as sustainable and resource-conserving, as it shortens downtime due to faster maintenance. It also reduces the amount of repair work resulting from imbalances. Even with an assumed energy reduction of just one per cent, electricity cost savings of several thousand euros can be achieved annually depending on the performance and number of machines.
