What does predictive maintenance mean for Industry 4.0?
Some modern sensors are necessary to implement predictive maintenance and avoid system failures, as they cost a lot of time and money. This is why predictive maintenance is used to avoid this problem. It is versatile and an important part of the 4.0 industry and the Internet of things.
Today, electric drives always emerge when mechanics have to be used for applications. Some examples are the linear drives, as well as electric drives a unit consisting of an electric motor with integrated gear. An optimal maintenance strategy can prevent failures of these electric drives and thus avoid plant downtimes. However, there are also unpredictable operating conditions, which result from the fact that a bearing in the electric drive changes over time or, for example, a gear wheel wears out. These signs of wear often creep in over a longer period of time and are not predictable. This means that there is a risk that the electric drive will eventually fail and have to be replaced. Depending on the application, the failure of a system can lead to very high costs and possibly associated production losses. Preventive maintenance and predictive maintenance measures are designed to prevent these costs and production downtimes. Preventive maintenance involves checking systems at fixed intervals. Predictive maintenance, on the other hand, determines the optimum time for the inspection itself and thus saves high costs. Integrated torque sensors can be used to record information on the condition of bearings or gears. Due to a change in the bearing, the friction and thus the efficiency of the system also changes. This process can now be measured. It is also possible to detect the degeneration of individual opinions
and use this information to recommend a maintenance interval at an early stage.
What are the stages of the predictive maintenance process?
1 Data is collected and processed by a torque sensor.
2 Data is analyzed.
3 Failure probabilities are calculated
Until now, torque sensors were not available for series applications because they were either too expensive or too large to be used. The new magnetic inductive technology for torque sensors from Magnetic Sense makes applications like these possible. The modular construction kit is also ideally suited for very large quantities in order to provide an optimum solution for the direct measurement of torques in electric drives and thus make a major contribution to preventive maintenance.
