R+W Antriebselemente GmbH
R+W - THE EK1 ELASTOMER INSERT COUPLING
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.
- Structure :
- Two coupling hubs manufactured with high concentricity, with concave shaped feed dogs
- Bore tolerance H7 + groove DIN 6885 + clamping screw DIN 916 or optionally pre-bored (DV)
- 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
- Elastomer insert: precisely manufactured plastic, extremely resistant to wear and temperatures
- Rotation speeds: standard, see table. Above 10,000 rpm, the couplings must be finely balanced (please specify).
- Technical characteristics :
- Rated torque: 0.5 - 2,150 Nm
- Rotation speeds up to 28,000 U/min
- Properties of the EK1 model elastomer coupling:
