THE PUNK® PRIME FAMILY

Utilising the unique Punk ‘Mohicans’ the Punk® Prime delivers high torque density, comparable to that of gear couplings. It is intended for high torque, low speed applications, such as steel mill rollers and industrial conveyor drives.
  • Misalignment to approximately 5 degrees
  • Easily assembled and disassembled, ideal for applications where ease of inspection and maintenance are required
  • Various sealing options available, including our novel seal cap design
  • All standard shaft interfaces can be accommodated; including key, spline, flange, tapered lock and clamp types
  • Can be concentrically supported, producing a multi-functional coupling and support bearing

IDEAL APPLICATIONS

  • Higher torque density
  • Lower misalignments
  • Lower speeds

TORQUE PATH

  • Torque is carried by the Mohicans bearing against the Mohican slots
  • Tangential contact loads minimise bearing pressures and bursting forces
  • Bearing pressure is distributed smoothly across the contact surface, making efficient use of material and improving wear characteristics

RADIAL LOAD PATH

  • Radial load is carried by contact between the nested spherical surfaces
  • Small clearances on the Mohicans protect them from radial load
  • The load capability is similar to the equivalent spherical bearing

AXIAL LOAD PATH

  • Axial load is carried by contact between the nested spherical surfaces
  • The axial load capability will be substantial but lower than the equivalent spherical bearing due to the Mohican slots

The Punk® Prime can deliver torque densities that rival the gear coupling, allied with superior angular misalignment capabilities. It excels in high torque, low speed applications. The key benefits of the Punk® Prime include
  • High torque density
  • Rapid assembly and disassembly, providing ease of inspection and maintenance
  • Progressive failure modes, preventing sudden system shut-downs

PUNK® PRIME EXTENDED

The Punk® Prime Extended is the Punk equivalent of a Flex-Rigid type gear coupling. It features an integral hub extension on the outer ring, which can house a range of shaft interface types and sizes. For most applications the input and output interfaces would be the same (e.g. keys), to couple shafts of similar dimensions.
  • Misalignment to approximately 5 degrees
  • Easily assembled and disassembled, ideal for applications where ease of inspection and maintenance are required
  • Various sealing options available, including our novel seal cap design
  • All standard shaft interfaces can be accommodated; including key, spline, flange, tapered lock and clamp types
  • Can be concentrically supported, producing a multi-functional coupling and support bearing

PUNK® PRIME DOUBLE SERIES

The Punk® Prime Double Series is our equivalent of the double Cardan shaft or Flex-Flex type gear coupling.

Two Punk® Primes are housed in a sleeve, creating a coupling that caters for both angular and parallel misalignments. The shaft interfaces are internalised giving much lower Distance Between Shaft Ends (DBSE) than achievable with an equivalent Cardan shaft, thereby reducing the footprint of your machinery.

  • The outer rings can be integral with, or mechanically fastened to, the sleeve.
  • Alternative designs connect the inner rings together with a small diameter solid shaft.
  • Split coupling options are available, using flanges.
  • The sleeves and shafts can be floating or fixed (axially).
  • Angular and parallel misalignment capability.
  • Easily assembled and disassembled, ideal for applications where ease of maintenance is required.
  • Various sealing options available, including our novel seal cap design.
  • All standard shaft interfaces can be accommodated; including key, spline, flange, tapered lock and clamp types.
  • Can be concentrically supported, producing a multi-functional coupling and support bearing.
