PUNK® PRODUCTS

All Punk® couplings are angular misalignment torque couplings, operating geometrically in the same way as a Universal Joint. Our three core products are the patented Punk® Prime, Gim-Ball and Failsafe couplings: each represents a family of couplings suited to particular applications dependent on speed, torque density and waiting failsafe requirements. Simply select the family that matches your needs to discover which of Punk’s nine functional variants could revolutionise your product range.

THE PUNK® FAILSAFE FAMILY

The Punk® Failsafe will remain operational in the presence of multiple element failures, making it ideal for high integrity drivetrains where reliability is key. Its performance is broadly similar to the Prime or Gim-Ball, depending on its detailed design.

Variants include the single, extended and double Punk® Failsafes. All are available with inner and outer attachments to your specifications.

IDEAL APPLICATIONS

 

  • WHERE ‘WAITING-FAILSAFE’ FUNCTIONALITY IS REQUIRED
  • ADAPTABLE TO PUNK® PRIME OR PUNK® GIM-BALL APPLICATIONS

THE PUNK® GIM-BALL FAMILY

The Punk® Gim-Ball provides unique systems integration opportunities over the universal joint, reducing both parts count and space envelope. This also offers high axial load capability, if required, and a dual torque path for inherent damage tolerance.

Variants include the single, extended and double Punk® Gim-Balls. All are available with inner and outer attachments to your specifications.

IDEAL APPLICATIONS

  • LOWER TORQUE DENSITY
  • HIGHER MISALIGNMENTS
  • HIGHER SPEEDS

THE PUNK® PRIME FAMILY

The Punk® Prime delivers torque densities comparable with gear couplings, allied with greater angular misalignments. Easily assembled and disassembled, this family is ideal for applications where ease of inspection and maintenance is required.

Variants include the single, extended and double Punk® Primes. All are available with inner and outer attachments to your specifications.

IDEAL APPLICATIONS

  • HIGHER TORQUE DENSITY
  • LOWER MISALIGNMENTS
  • LOWER SPEEDS

THE PUNK® BOT

The PunkBot obtains its impressive capabilities because of our innovative technology.

The PunkBot module is comprised of our unique Punk® Conical Actuator and Punk® Concentric Flexible Driveshafts, which both utilise our original geometric philosophy

IDEAL APPLICATIONS

THE PUNKBOT IS EMINENTLY SUITED FOR OPERATING IN HAZARDOUS ENVIRONMENTS AND DIFFICULT TO REACH SPACES. ITS MAIN SPINDLE DRIVE MOTOR AND CONTROLLER ARE SIMILAR TO THAT OF A STANDARD CNC MILLING MACHINE, ALLOWING:

  • THE MACHINING OF A WIDE VARIETY OF MATERIALS DUE TO THE BROAD RANGE AND SEAMLESS VARIABILITY OF THE SPINDLE SPEEDS
  • THE USE OF ALL TYPES OF CUTTERS
  • THE USE OF TAPPING HEADS

THE PUNK® CONICAL ACTUATOR

The Punk® Conical Actuator uses the ‘worm and wheel’ principle of motivation, with the ‘Mohican’ feature of the Punk® Prime torque coupling incorporated into the wheel element. A pair of worms, driven by servo motors, rotate in the same direction to position the wheel. Once in position, one of the worms is reversed to take up the backlash, creating a clamped situation that can resist very large forces.

IDEAL APPLICATIONS

  • FIELD OF MOTION +/- 15°
  • RIGIDLY LOCKS INTO POSITION
  • REACTS EXTREMELY LARGE FORCES

THE PUNK® CONCENTRIC DRIVESHAFT

The first driveshaft system with two separate but concentric flexible drivetrains.

This allows torque to be transmitted using:

  • Differential speeds
  • Contra rotating driveshafts
  • One dynamic drivetrain and one to statically react the torque of the other

IDEAL APPLICATIONS

OUR PUNKBOT DEMONSTRATES HOW THE CONCENTRIC FLEXIBLE DRIVESHAFTS COULD BE USED IN ROBOTIC EQUIPMENT OPERATING IN HAZARDOUS ENVIRONMENTS.
HOWEVER, THIS IS NEW TECHNOLOGY WITH NEW FUNCTIONS AND WE ARE ACTIVELY SEEKING AREAS WHERE IT COULD BE APPLIED.
