R+W Antriebselemente GmbH

R+W - ST4 TORQUE LIMITER

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.

WEAR-RESISTANT AND ROBUST: INDUSTRIAL COUPLINGS FROM R+W

Long service life, reliability and flexibility: thanks to these qualities, industrial couplings are perfect for all areas of application that require maximum safety and performance despite constant extreme loads. Indeed, any downtime, any failure or any breakdown causes costs to skyrocket and can lead to technical damage or workplace accidents, whatever the industrial sector.

The requirements for the reliability of assembly elements are therefore as high as those for their areas of use. Industrial couplings must

o    
transmit extremely high torques with minimal performance losses,

o    
resist wear, even when subjected to extreme stress, and

o    
protect facilities and minimize risks.

R+W combines all these qualities in innovative couplings for industrial construction. Special customized solutions are made for many applications, but there is a wide range of standard couplings in which any company can find the product that suits them.

Technical details

  • Structure :
    • Keyed or multiple wedges.
    • Toothed coupling for offset housing.
    • Interlocking segments distributed around the circumference.
    • Adjustable within defined range.
  • Temperature range: -30 to +120°C
  • Lifespan: torque limiters are very durable and maintenance-free if the technical instructions are followed.
  • Tolerance clearance: of the shaft-hub connection 0.02 - 0.07 mm
  • Material :
    • Safety element: high-strength hardened steel (oxidized surface)
    • Toothed couplings on both sides: toothing made of high-alloy steel, extremely wear-resistant
    • Surface treated with anti-rust (oxidized)
  • Properties of the torque limiter, model ST4:
    • High power density
    • Torque from 1,000 to 160,000 Nm
    • Compensation of axial, lateral and angular shaft bearings
    • Puncture resistant
    • Low restoring forces
