Siemens introduces digital ­measurement technology for gears

Siemens unveiled its digital measurement technology for gears, Flender Gearlog, for the very first time at the Hannover Messe 2016. This new technology entails the capture of values relating to rotational speed, torque, temperature and in the future also vibration by special sensors. The system adds up these readings in parallel with machine capacity utilization. The measurement results are logged, saved and digitally depicted in compressed form. Operators are able to visualize the results at any time or read them out in the form of a dataset. The measurements enable conclusions to be drawn about the applied load and loading capacity of gears when used in specific applications. The full transparency of operating data means it can be used to identify possible sources of damage, capacity reserves and overloading in the measured gear. Flender Gearlog allows application-specific load collectives, which often vary for operational reasons, to be matched against the operational stability of individual gear components and also other elements of the drive train. In this way, customers can find an optimum standard gear – working machine match.

Flender Gearlog comprises a software solution linked to a hardware component and sensor equipment coordinated in line with the gear. Siemens also offers services such as installation and commissioning, secure access to all data, regular evaluation of data and status reports. Special algorithms are used to compress the time signals and depict wide-ranging information relating to operating data on a digital basis. If threshold values are exceeded, Flender Gearlog also records time signals, allowing any detected overloads, for instance, to be additionally analyzed. All the data necessary for this is already available locally, or in future also in the cloud. The measurements can be performed on all available Flender gears, both catalog and non-standard types, for instance for the mining, cement or oil and gas industry, for wind turbines and cranes. A pilot phase for the product of around one year with interested gear customers has started with the Hannover Messe.

Flender Gearlog represents the very first entry of a mechanical component into the digital world of industry: This hardware component represents a bridge between gear and software. The digital depiction of gear load data permits an insight to be gained into operating reliability, availability and productivity in cooperation with Siemens experts.
