Key-Eng standard couplings

In machinery systems, drivetrains are made up of single components such as engine, gearboxes, shafts and work machine. These components are joined together by couplings and the tasks of these couplings are:

  • Transfer of rotary motion and torque
  • Compensation of shaft attitude (radial, axial, angular)
  • Reduction of torsional vibration
  • Damping of torque and acceleration shocks
  • Limitation of the torque (safety couplings)
  • Acoustic insulation



  Gear Couplings STC series

  • Double-cardanic all-steel coupling
  • Compensation of angular deviations, parallel and axial misalignment
  • Torque range, from 1.800 to 203.000 Nm
  • Long-term lubrication in consequence of design features and the use of special seals
  • Ambient temperature -40 ° .. 120 ° C
  • Applications: generators, pumps, compressors, mills, agitators, synchronous drives, machine tools, general mechanical Engineering

 

 

  Multi-Disk Couplings SLC series

  • Free from backlash, torsional rigid and maintenance-free all-steel coupling
