R+W Antriebselemente GmbH
R+W - SKN TORQUE LIMITER
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 GUARANTEED SAFETY IN THE EVENT OF OVERLOAD: TORQUE LIMITERS FROM R+W
Many factors can cause overloads. Torque limiters from R+W guarantee a quick and reliable separation between drive and output side when a predefined torque is exceeded.
THE TECHNICAL BASIS: THE PRINCIPLE OF ENGAGEMENT OF THE R+W TORQUE LIMITER BALL
Mechanical torque limiters from R+W operate according to the spring-loaded ball engagement principle and serve as the ultimate emergency stopping elements of machines. Characteristic of the torque limiter operating mode: the high rigidity of the elements and the complete absence of play. If the torque exceeds the defined threshold, the balls engage and separate the drive side from the output side.
- Structure :
- Structure: with clamping disk and respectively an ISO 4762 side screw.
- Absolutely play-free thanks to tight force-bond connection.
- Temperature range: -30 to +120°C
- Backlash: Absolutely backlash-free thanks to a tight, force-bonded connection and a proven principle.
- Lifespan: torque limiters are very durable and maintenance-free if the technical instructions are followed.
- Tolerance clearance: of the shaft-hub connection 0.01 - 0.05 mm
- Material :
- Safety element: highly resistant hardened steel
- Clamping disk: up to series 500 in aluminum, from series 800 in steel
