New, backlash-free Flender couplings facilitate high positional accuracy

12.10.2015

SPS IPC Drives 2015, Hall 11

  • Can be used in production and machine tools, as well as automation engineering
  • Bipex-S elastomer coupling for applications subject to vibrations and shocks
  • Torsionally rigid Sipex metal bellows coupling for angle-preserving torque transmission

Siemens has completed its portfolio of couplings with the addition of the new backlash-free Flender Bipex-S and Flender Sipex couplings. Both coupling versions can be used in production machines and machine tools, as well as in automation engineering.

They are available in various sizes and can be installed in integrated drive systems, frequently in combination with servo motors. Bipex-S torsionally flexible elastomer couplings are used in applications subject to vibration and shocks; Sipex metal bellows couplings are used in drives that require an absolutely angle-preserving torque transmission.

High-precision applications in machine tool manufacturing, control engineering and processing industries demand a great deal from the performance, quality and precision of couplings and their process reliability. Backlash-free couplings with reliable power transmission form the modular interface between motor and drive machine. They also compensate for offsets between the coupled units.

The backlash-free, breakdown-resistant and vibration-damping Bipex-S couplings are characterized by high power density and electrically isolating properties that protect against leakage currents. They enable a high degree of positional accuracy and reduce the wear on the system through lower peak loads and vibrations. The axial plug-in enables blind assembly. If the elastomer wears away completely, the jaws of the coupling hubs provide emergency running properties.

The extremely torsionally rigid Sipex couplings facilitate angle-preserving torque transmission, which consequently provides the highest positional accuracy. They are non-wearing and maintenance-free, reduce unplanned system and machine downtimes which, in turn, increases system availability. The excellent, true-running properties of the couplings make them particularly suitable for high speeds. Low restoring forces, almost no bearing load in the coupled machines and a good power density round off their positive properties.

The new, backlash-free Bipex-S and Sipex Flender couplings are each available in six hub versions, which enable optimal connection to the shaft ends of the coupled units. They have a low moment of inertia, require little installation space, are easy to mount and are very suitable for use in integrated drive systems. Both series of couplings are used in control, automation and medical engineering, as well as in production machine and machine tool manufacturing. They are installed, for example, in positioning drives, stepper motors, linear units and handling robots.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
