SKF Machine train alignment
Read full descriptionHide full description
The Machine train shaft alignment app is designed to be used with the SKF Shaft Alignment Tool TKSA 71. Together, the TKSA 71 and the app form an alignment system that allows the alignment of machine trains with multiple connected machines in an intuitive and easy way. The system uses line laser to PSD technology that enables highly accurate and reliable shaft alignments. The TKSA 71 and this app communicate wirelessly via Bluetooth®. Without the hardware the app can nonetheless be used, as it features a fully functional demonstration allowing the complete alignment process of a machine train to be experienced before purchasing the TKSA 71. KEY FEATURES: • Very easy-to-use – The Machine train shaft alignment app focuses on making the alignment tasks of several couplings as easy as possible and enabling accurate machine train shaft alignments. • Quick Three Point Alignment Measurements - Follow the guidance of the app and perform a full 9-12-3 measurement or perform a limited rotation measurement with as little as 40 degrees of total rotation. • Selectable stationary feet – The alignment process records the complete alignment situation and allows the operator to select two pairs of stationary feet. The app then calculates the required machine movement for all feet while keeping the stationary feet pairs at the same location. The operator can easily find the best alignment strategy by selecting different pairs of stationary feet and checking the required movement for the alignment correction. • The machine train app is designed for machine trains of three machines, covering common machine trains like motor – gearbox – application combinations. • Demonstration mode – The Machine train shaft alignment app offers a fully functional demonstration mode allowing the complete alignment process to be experienced before purchasing the TKSA 71. • Automatic alignment report – Automatically generated alignment reports give a complete overview of the alignment process and results. The reports can be customized with additional notes, a machine picture and a signature. The report can easily be shared via email or cloud services. • Easy to follow explanatory videos – Short explanatory videos are available in the help section of the app and show in easy steps how to set up and perform accurate alignment measurements. • 3D Animations – 3D animations intuitively guide the user through the alignment process, allowing accurate shaft alignment to be performed in a very easy way. • Machine library and QR code scanner – Helps keeping track of the machines that have been measured. Machine information like distances, the machine picture, and other details are saved for each machine and can be reused the next time the same machine is measured. QR codes can be scanned to identify a machine and quickly retrieve its details. The library can also be used for easy access to all the reports generated for each machine in one place. HARDWARE – SKF Shaft Alignment Tool TKSA 71: The SKF TKSA 71 system uses a pair of measurement units that are combined with laser transmitter and detectors to measure and correct shaft alignment with high accuracy and reliability. The data is transferred in real time through Bluetooth® 4.0 LE to the app. IMPORTANT NOTE: This app is designed to be used with the SKF Shaft Alignment Tool TKSA 71 hardware. The SKF TKSA 71 can be purchased separately from your local SKF Authorized Distributor. For more information and technical specifications about the SKF Shaft Alignment Tool, please visit our website.

The ONEPROD Bearing Defender is the result of 30+ years of experience in predictive maintenance and is based on the Defect Factor™ technology. It provides bearing fault frequencies calculation and automatic diagnostic within seconds with the ONEPROD wireless vibration sensor. Predictive Maintenance has proven benefits for the reliability of industrial assets. However, vibration analysis has always been complex and accessible to expert users only. Now, by computing automatically the triaxial wireless measurements, the ONEPROD Bearing Defender makes sure that your rotating machinery can keep spinning without risk, and without any expertise needed. Regardless the position of the wireless sensor on the bearing, a full and reliable vibration analysis of the machine is automatically performed. Even mechanical faults like unbalance or structural resonance that may arise in a single direction can be detected. You don’t need to be an expert to handle this vibration measurement and diagnostic application. With its smart automatic indicators, the bearing defender application clearly presents the bearing health condition, the presence of unbalance or misalignment problem, and is even able to tell if another type of fault may put your rotating machine at risk. The results are displayed in addition to the ISO10816 standard alarms on a single screen, and work with colors to make your assets faults easy to identify. The main functions are: - Bearing fault frequency calculator on 30.000+ bearing references - Three directional vibration measurements (velocity, acceleration, displacement), in X, Y, and Z directions. - Automatic comparison of the vibration velocity to the ISO10816-3 standard and display of the vibration alarms in a color code (green, yellow, red) - Automatic diagnostic of the bearing health condition (bearing wear or lubrication problem), unbalance or misalignment, or other fault. - Live audio signal listening of the signal measured by the sensor, e.g. while greasing your bearing - 3D spectrum display merging X Y and Z directions for easy vibration diagnostic confirmation: the ONEPROD ZYXtrum™ - Easy reporting capabilities thanks to the screenshot function - Possibility to upgrade to an expert solution in vibration analysis as the wireless sensor compatible with the ONEPROD Bearing Defender is also compatible with the ONEPROD FALCON portable analyzer. The ONEPROD Bearing Defender app is universal and can be understood by any user: icon based HMI, selectable vibration units (metric or imperial units).
