Connection couplings

Voith connection couplings provide a backlash-free, frictional, quick-setting/releasing shaft-hub connection. The setting or releasing occurs hydraulically. Depending on the application, various operating principles are available, all of which offer the advantage of a backlash-free pressure connection.

HyCon

• Mechanical shaft-shaft/shaft-flange connection
• Hydraulically set and released
• No oil pressure required for transmitting torque

The inner and outer tapered sleeves are hydraulically pushed towards each other to create a radial force. Subsequently, a frictional connection is created between shaft, coupling and shaft/flange.
During setting and releasing, the shaft hub remains static, only the tapered outer sleeve is moved.

HyGrip

• Hydraulic hollow sleeve-shaft-hub connection
• Pumped up hydraulically
• Oil pressure is required for transmitting torque

The frictional connection between the shaft, coupling and hub is created by hydraulic expansion of the coupling unit.
The hydraulic pressure creates a radial force within the coupling.
During setting and releasing, the shaft hub re­mains static.

HyLoc

• Mechanical shaft-hub connection
• Hydraulically set and released
• Oil pressure is not required for transmitting torque

By hydraulically pushing a tapered sleeve inside a coupling unit, a radial force is created. Subsequently,
a frictional connection is created between shaft, coupling and hub.
During setting and releasing, the shaft hub remains static, only the tapered conical sleeve inside the
coupling moves.
