KTR Varolastic highly flexible flange coupling

KTR Varolastic highly flexible flange coupling

Our Varolastic series from KTR is a highly flexible flange couplings with progressive torsional stiffness ideally suitable for main drives. Types F and FD (fail safe) available.

Features Varolastic F and FD:

• Insulation of vibration amplitudes on the drive side
• Axial plug-in
• Maintenance-free
• Consider axial displacement

Type F:

VAROLASTIC F is a progressive flange coupling that is characterized by its variable torsional stiffness.The non-linear roller coupling as a version F is available for compatible flywheel connections and a number of hub connections as a standard. A failure protection against slipping is available for type FD only.The elastomers allow for an installation space temperature of 120°C permanently and up to 150°C for a short time.

VAROLASTIC F is a particulary good choice for variable-speed main drives (e. g. in combination with gearboxes) or wherever a sturdy coupling able to take overload is looked for. Since the torsional stiffness optimally adapts to the tasks each depending on the application, the VAROLASTIC® also serves the trend of component standardisation via the sizes and innovation cycles in the customer portfolio.

Type FD:

VAROLASTIC FD is a progressive flange coupling that is characterized by its variable torsional stiffness. In the real operating range this characteristic always provides for an optimum torsional vibration condition: With small load torques it is particularly torsionally soft gaining torsional stiffness with increasing load to ensure the full power transmission. The progressive torsional stiffness characteristic curve is achieved by special elastomer rollers precisely guided and loaded in a convex-concave contour guide.The synthetical elastomers of VAROLASTIC FD allow for a maximum operating temperature of 120 °C permanently and up to 150 °C for a short time. Type FD is a particularly good choice for main drives susceptible to torsional vibrations.

Thanks to the customised adaptation of torsional stiffness to the respective tasks, VAROLASTIC FD supports the trend towards component standardisation as well.VAROLASTIC is available as a standard as type FD with anti-rotation device as well as for compatible flywheel connections and a number of hub connections.Extremely excessive torques generate a soft stop. In contrast to classic solutions this load point is dimensioned such that the elastomer rollers are protected against shearing resp. fracture while the coupling is still fully applicable.
