Torque limiters - SK

No backlash and compact construction
For torques 0,1 to 2.800 Nm
Shaft diameters from 3 to 100mm

Properties of torque limiters type SK:

• Fine-tuning the torque limit
• Torsional rigidity, version with no backlash with patented R&W system
• Simple compact construction
• Low moment of inertia
• Long overload trip
• Quick shutdown in millisecond range
• Low residual friction after disengagement

VARIOUS OPERATING SYSTEMS:

 

Each coupling model is available in one of the four models described!

Single position engagement - W (standard)

• After the overload has been removed, the safety coupling will re-engage precisely 360° from the original disengagement position.
• Reliable principle guarantees synchronous operation.
• Signal at overload to detect with mechanical switch or proximity sensor.
• Suitable for use in machine tools, packaging machinery, automation systems and other applications requiring precise timing.

Multi position engagement - D

• The coupling pops out of th ball notch when overloaded and automatically locks at the next ball notch after the interval of the selected angular distribution.
• Immediate availability of the machine as soon as the overload has been removed.
• Signal at overload to detect with mechanical switch or proximity sensor.
• Standard engagement after 60°.
• Engagement after 30, 45, 90 and 120 degrees optional.

Load holding version - G

• Mechanical overload detection device.
• In the event of an overload, the drive and the driven elements are not fully separated and are only allowed limited rotation.
• Automatic engagement after the torque level has dropped.
• Guranteed to hold the load and signal an overload.
• Signal at overload to detect with mechanical switch or proximity sensor.
• Suitable for use on presses, load lifting equipment and where the drive and driven elements can not be separated.

Full disengagement version - F (Warning: the coupling must be switched manually!)

• Permanent separation of driven and driven elements in the event of an overload.
• No residual friction.
• Signal at overload with mechanical switch or proximity sensor.
• Rotating elements slow down freely.
• Coupling can be re-engaged manually (Engagement every 60°); other engagements available.
• For use in high speed applications.
