Industrial Flexible Couplings

MULTI MONT SELLA, DEKA, GIGANT

MULTI MONTMULTI MONT couplings have been built in series since 1958. This pluggable claw coupling that has been successfully proven over a number of decades has been permanently updated to the state of the art, and the MULTI MONT SELLA, MULTI MONT DEKA and MULTI MONT GIANT series nowadays cover a torque range from 40 to 1 000 000 Nm.


Advantages of MULTI MONT-SELLA, -DEKA, -GIGANT:

  • compensate for axial-, radial- and angular misalignments
  • absorbs shocks & vibrations, this protects equipment & prolongs its life
  • can be optimized with different rubber types to further enhance performance under all operating conditions
  • series spans 22 sizes covering torque ranges from 40 Nm to 1 000 000 Nm
  • Easy inspection of rubber blocks in-situ, saves maintenance cost of realigning equipment
  • are well suited as plug-in type couplings ensuring ease of assembly and alignment
  • allow prompt and easy radial change of the flexible elements
  • are maintenance-free
  • are customizeable for almost every type of mounting situation

FLEXDUR

flexdurFLEXDUR-couplings are flexible compensating couplings of all metallic design which transmit the torque in a torsionally rigid and backlash-free manner. The transmission elements are disc packs of stainless spring steel plates which are attached to the coupling components by closetolerance bolts.

The most important characteristics and advantages of FLEXDUR-couplings:

  • Torsionally rigid torque transmission with zero torsional backlash
  • Wear-free compensation of axial, radial and/or angular shaft displacements
  • little restoring forces in the case of shaft displacements
  • Neither maintenance, nor lubrication required
  • For use at ambient temperatures from – 25 °C to + 250 °C
  • Compact design even suited for high and very high rotational speeds
  • Almost unlimited lifetime and wear-free with proper shaft alignment

MULTI MONT ASTRA

multi_mont_astra

The flexible Reich MULTI MONT ASTRA coupling is a fail-safe claw coupling with flexible element for a torsionally flexible shaft connection. The advantages of the all over machined MULTI MONT ASTRA coupling, and of the claw flanks in particular, are the precise running characteristic and the extended service life.

The most salient characteristics and advantages of the MULTI MONT ASTRA claw coupling:

  • compensate axial-, radial- and angular misalignments
  • absorb shocks and vibrations
  • fail safe and withstand high overloads
  • The series covers a range of 10 different sizes with nominal torques from 10 Nm to 2400 Nm
  • well suited as plug-in type couplings ensuring ease of assembly and alignment
    maintenance-free
  • can be supplied with taper lock bushes & supplied with various flexible element types.

ArcuDent tooth coupling

tooth

The ArcuDent tooth coupling is a double-jointed steel coupling. The teeth of the hubs and covers receive shape corrections to allow the highest misalignment capacity. It is a flexible, but nonetheless torsion-resistant coupling.

The most important characteristics and advantages of ArcuDent tooth couplings:

  • Finite element analysis
  • Ring Gear: Gear Teeth optimized by finite elements
  • Oil Tightness with standard o-rings that guarantee the long life of couplings
  • Special gear tooth shape realised in order to reduce superficial pressures and to limit noise and vibration interferences.
  • Gear Hub: Bore hub capacity up to 800 mm optimization by finite elements
  • Grade 12.9 screws allow for friction face locking of torque transmission
  • EX-safety according to ATEX-standards

REIBO

reiboREIBO couplings are torsionally flexible pin-type couplings which compensate for radial, axial and angular shaft displacements. REIBO couplings are designed for positive (fail safe) torque transmission and for absorbing vibrations and torque surges.

Salient features of the torsionally flexible REIBO couplings:

  • Compensation of axial, radial and angular misalignments
  • Shock load and vibration absorbing capability
  • Fail safe operation
  • Available in 18 sizes: from 150 Nm – 350 000 Nm
  • Ease of assembly and ease of alignment
  • Plug-in mounting facility
  • No maintenance required
  • Available in different types or as special designs
