New, backlash-free Flender couplings facilitate high positional accuracy


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: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
