Schaeffler’s BearinX calculation tool retrieves the data from the cloud. The customer can then view the remaining useful life of every bearing in the machine using an internet-capable end device. Schaeffler’s solution is based on three central elements: • A suitable system of sensors gathers reliable load data for the machine and its bearings. • Simulation models calculate the remaining useful life based on the dimensions of the machine and the actual loads. • A software platform through which the customer can access the calculations and retrieve information about his or her machine individually. Schaeffler’s BearingX calculation tool retrieves the data from the cloud and calculates the nominal rating life of the individual bearings. The calculation is based on loads such as speeds, torques, temperatures, and vibrations. To back the system, Schaeffler Australia offers a full range of maintenance tools and condition monitoring equipment and services from a single source. Included in the range are hand-held data collectors for patrol monitoring, to modular online fixed vibration monitoring systems and easy-to-use acoustic emission monitoring devices. Services include vibration analysis, thermographic imaging, oil analysis and complete after-sales service by fully qualified engineers and for any application in any industry. Optimum maintenance intervalPlanning While condition monitoring provides information about a machine’s current condition, predictive maintenance also looks into the future and allows the optimum time for maintenance to be predicted. Dr Hans-Willi Keßler, vice president of service products at Schaeffler, says this allows factories’ production planning to be optimised. “For example, production can be increased if this is required to meet increased order and sufficient machine capacity is available. Alternatively, production can be reduced when there are fewer orders pending in order to match a specific maintenance interval.” In this way, production machine maintenance can be carried out based on the load conditions and according to requirements instead of specific time intervals and acute malfunctions, he says. This provides numerous benefits, including increased productivity through correlation between the level of capacity utilisation in production and the condition of the machine elements. What is more, replacement parts can be ordered on a just-in-time basis, which reduces warehousing costs. Last, but not least, the overall operating costs can be lowered through optimum utilisation of maintenance intervals. Even in the event of incipient bearing damage, predictive maintenance can still help: If the operator knows how long a bearing will continue to function, he or she can make a valid decision as to whether or not production should be continued. By carrying out maintenance work in accordance with the actual operating conditions, Schaeffler is ushering in a paradigm shift in mechanical engineering. In a second step, the measured load spectra can be used to completely redesign and reconfigure both individual components and entire machines to match the relevant load conditions.
