Safety Couplings

Safety Couplings

Safety, or also overload, couplings feature extremely short response times, 3 to 5ms, which results in an almost on the spot torque break. All KBK safety couplings offer variable torque cutout that can be set. In comparison to other safety mechanisms like an electronic cut-off or the classic frictional slip hubs, the safety couplings offer different advantages. So the safety of human and machines is assured in case of a machine crash. It is a reliable method to use safety couplings to prevent accidental personal injuries as well as long standstills and high maintenance costs. Furthermore, they are insensible against environmental circumstances like thermal fluctuation or contacts with lubricants which specially cause negative effects on slip hubs.

The following disengagement mechanisms can be chosen:

  • single - position (version C), the safety coupling will reengage precisely 360 from the original disengagement position
  • multi - position (version D), coupling reengages at multiple set angular intervals (e.g. 45, 60)
  • blocked (version G), coupling disengages in case of overload but keeps transmitting the torque

Some typical applications for KBK safety couplings:

  • Machine tools
  • CNC machines
  • Wood working machines
  • Factory automation machinery
  • Textile machines
  • Sheet metal forming machines
  • Printing machines
