The new Shaft Locking Assemblies and Devices, now available from PIES Australia , have been designed to connect components onto a shaft by static friction, giving them the ability to transmit high torque and absorb an axial thrust. The shaft locking devices can be used as an alternative to conventional fastening methods such as weldings, splines, keyways and taper lock bushes, as they are self centering devices and clamp components securely to the shaft with no backlash and without the need for high tolerance bores.  

These shaft locking devices are suitable for a wide variety of applications, including the connection of:

  • Timing pulleys
  • Flywheels
  • Flat belt pulleys
  • Belt and rope pulleys
  • Chain sprockets
  • Gears
  • Levers
  • Disc cams
  • Eccentrics
  • Brake plates
  • Flanges for reducers
  • Couplings
  • Drums for conveyor belts
  • Lift drives
  • Conveyors
  • Compressors
  • Diesel engines
  • Glass and ceramics
  • Automatic machines
  • Packaging machines
  • Presses
  • Mills Crushers  
The shaft locking devices only require a low tolerance parallel bore (H8), decreasing expenses by eliminating the need to machine taper bores, keys and keyways, splines and welding. Downtime is reduced due to the easy installation and elimination of expensive machinings such as keyways and their final adjustment.  

Supplied as shaft locking assemblies, these shaft locking devices consist of two cut rings, one fitted into the other, with conical mating surfaces and the associated clamping screws. By tightening the screws alternately, the conical surfaces of the cut rings are pushed one into the other. The radial deformation created generates a pressure on the components to be connected, allowing the true clamp fit of the assembly in the desired angular and axial position.
