R+W - THE EK7 ELASTOMER INSERT COUPLING

Description

  • For over 30 years, R+W Antriebselemente GmbH has been manufacturing couplings, torque limiters and shaft lines for the whole world from 0.05 Nm to 2000 kNm that could meet your needs. In addition to a wide range of products, we can also offer you special couplings totally adapted to your applications.

     

    FOR MAXIMUM PRECISION AND DYNAMICS: ELASTOMER COUPLINGS FROM R+W

    The main advantages of elastomeric couplings are: vibration absorption, pluggable, zero backlash and electrical insulation. They are used in the following areas: Control technology, machine tools, packaging machines, automation systems, printers, control and positioning equipment, general mechanical engineering, pumps and mixers or roller door motors: depending on their function, the areas of use of the elastomer coupling are as varied as your requirements.

Technical details

  • Structure: two coupling hubs manufactured with high concentricity.
    • Side 1: clamping hub with one ISO 4762 side screw
    • Side 2: Inner cone expanding chuck and ISO 4762 screw. Recommended bore tolerance for expanding chuck: H7. Elastomer insert available in three versions.
  • Temperature range: depending on the elastomer insert chosen.
  • Torsional stiffness: In order to optimize the drive unit, we offer different Shore hardnesses for the elastomer inserts.
  • Tolerance clearance: of the shaft-hub connection 0.01 - 0.05 mm
  • Material :
    • Coupling hubs: up to series 450 made of high-strength aluminum, from series 800 made of steel
    • Inner cone + expanding mandrel: steel
    • Elastomer insert: precisely manufactured plastic, extremely resistant to wear and temperatures
  • Rotation speeds: standard, see table, depending on series up to 4,000 and 22,000 rpm. Above 4000 rpm the elastomeric coupling must be finely balanced (please specify).
  • Technical characteristics :
    • Rated torque: 2 - 2,150 Nm
    • Rotation speeds up to 22,000 rpm
  • Properties of the EK7 model elastomeric coupling:
    • Possible axial mounting of the hub with expanding mandrel
    • Very good clamping forces
    • Very good concentricity
    • Short construction form
    • Easy assembly
    • Axial mounting possible on pivot side
    • Backlash-free claw coupling
    • Electrical insulation
