Shaft couplings for high-speed applications
May 13.05.2024, XNUMX | Drive axles in high-speed use require reliable couplings: Mayr is presenting overload protection and compensation for shaft misalignment at the Testing Expo 2024 in Stuttgart its new models for test bench technology.
Based on the Roba DS The drive specialist is now introducing a weight-optimized series made of aluminum. The outer diameter was comparatively reduced by up to 10 mm. The mass and inertia are 40 to 60% of the steel version - with the same power density. The aluminum coupling is tailored for high-speed applications such as those required in test bench technology.
Shaft compensation couplings are indispensable components in test benches because they minimize parasitic forces caused by misalignment in the drive train. These forces, caused by offsets between the input and output sides, affect the accuracy of measurements. The use of shaft balancing couplings that are precisely designed for measuring flanges and high speeds therefore improves measurement accuracy. Only when the balance between rigidity and elasticity is right can restoring forces on the system be avoided.
Mayr's shaft balancing couplings are characterized by their compactness and high power density. They are for high speeds up to 30.000 min-1 designed and offer low mass and inertia. Their precise manufacturing ensures smooth running and optimal balancing quality. When selecting, it is crucial to consider the specific requirements of the application - including speeds, load changes, load cycles, bearing clearances and bore diameters - to find the best balance of material properties and application conditions.
Reliable protection against overload at high speeds
If the torque on a test bench exceeds the limit set on the safety clutch, the clutch releases immediately and separates the input and output within fractions of a second. This rapid disconnection prevents expensive damage to the drive train or the test object, although the measurement shaft may need to be recalibrated after an overload event.
Claw couplings | With elastomer as a performer
The EAS HSE safety clutches are characterized by backlash-free torque transmission and high torsional rigidity. Their compact, power-dense design results from a small outside diameter in relation to the larger bore diameter. Specially selected, symmetrically arranged transmission elements are integrated into the couplings, which contribute to the low vibration of the system and ensure precise function in the event of a trip. Careful coordination of the dimensions of the bore diameter, outside diameter and element size is crucial for the performance of the safety couplings.
Torque measuring shaft coupling with integrated sensor
Oct 18.03.2024, XNUMX | Mayr drive technology presented at the Hannover Messe 2024 smart clutches like the new multi-plate clutch made of steel Roba drive checker, which can transmit more than torque and compensate for shaft misalignment. Rather, they offer users the chance to get to know their processes in detail.
Shaft couplings at the scene
"Couplings are important building blocks in the powertrain. They sit right where the action is, so to speak, and are therefore predestined for intelligent people monitoring concepts", explained Ralph Eple, product manager at Mayr in Mauerstetten. “The goal is the intelligent clutch that gives us information about the status of the drive train. That brings decisive advantages.”
Through permanent condition monitoring, the coupling makes parameters and abnormalities in the process visible quickly and reliably. The shaft coupling can be easily installed via an M8 network connection Remote maintenance systems integrate.
Predictive maintenance with high functional reliability
This makes it suitable for predictive maintenance, lowers maintenance costs and reduces technical defects and downtimes. The Roba-drive-checker is designed for use in industrial environments. It is insensitive to external disturbances and offers thanks IP6X Certification also ensures a high level of functional reliability.
Instead of installing a complex measuring flange or something similar in the drive train, shaft couplings were installed in the drive train Sensors integrated. This saves developers and users space and other components. "Our Roba-drive-checker coupling is based on the standard Roba-DS steel lamina coupling and can therefore be easily integrated into many existing applications," adds Ralf Epple. This approach is particularly attractive for Process monitoring. In addition to precision, cost-effectiveness also plays an important role here. "We consciously set ourselves apart from high-quality measurement technology and measurement systems from the test environment, which pursue a different goal," Ralf Epple specifies.
Roba-drive-checker in disk pack clutch
The Roba-drive-checker is a new component in the backlash-free disk pack clutch kit Roba DS. The core elements are the multi-Gateway and the Roba drive checker sleeve. With all the available connection options for the steel disc coupling, this cost-effective process monitoring can be easily integrated into many existing applications. There is also a connection to EASsafety clutches is possible.
The Multi gateway can be easily positioned and configured thanks to optical position markings and with the help of an intuitive configuration assistant. It inductively supplies the rotating sleeve with energy, manages the radio connection and provides the measurement and system data in the network.
Battery changes or charging processes become unnecessary. The permanent ensures this wireless power supply. “The sleeve, installed between two Roba-DS disk packs, records the torque using proven DMS technology,” explains Ralf Epple and mentions further advantages: “The user retains complete control over the data transmitted from the sleeve to the multi-gateway . External cloud systems or third-party software are not necessary. The Roba-drive-checker is a 100% development by us. We deliver the system as a complete package from a single source.”
Intelligent shaft coupling for predictive maintenance

Elastomer coupling with new hubs and spacers
09.08.2019 | When it comes to automating production and assembly, loading and unloading machines quickly and efficiently, or handling workpieces, all movements must be carried out precisely. That's why they have to Couplingsthat the torques from the drive unit for example on the guide of a Gripper transfer, work with high precision and at the same time withstand the high loads.
Mayr offers a few options for this backlash free, powerful metal bellows couplings, elastomer couplings and multi-disc clutches for a secure connection from shaft to shaft - from the servo coupling via the industrial clutch up to the heavy-duty coupling.
Geiger Handling relies on the Gimatic gripper portfolio
For the reliable protection of machine tools and machining centers With its clutches and brakes, Mayr offers complete solutions from a single source. For example, a wide range of backlash-free, high-performance servo couplings ensures a secure connection between the shafts. Depending on the application, these servo couplings are subject to very different requirements.
That is why the drive specialist has various metal bellows, elastomer and disk pack couplings in its range. The company has recently added numerous new hub designs and spacers to its standard modular system – most recently a new, long spacer for the Roba-ES elastomer coupling With the wide range of variants, the company is able to offer solutions for all drive constellations in servo technology, quickly and easily. Because the intelligent modular system also ensures high availability, short delivery times for standard components and low prices.
