The Punk® Nut

The PunkNut is the first self-aligning and translating leadscrew and ball nut.

The PunkNut allows:

• Accommodation of misalignment and mounting tolerance issues that critically affect reliability and longevity
• Faster installation as it accurately self-aligns
• Accommodation of structural movement and flexing, which prevents screw bending and nut binding
• New uses for linear actuators

The PunkNut accommodates single or double axis misalignment up to +/- 15° without any increase in load or wear on the system.

• A two ring system can be used to accommodate angular misalignment in a single plane.
• A three ring system can be used to accommodate angular misalignment in two planes.

Punk® geometric philosophy is radically different and represents a completely new type of technology to support mechanical power transmission and linear motion. Punk® geometric philosophy can be applied to leadscrew and ball screw nuts in linear actuators as a means of accommodating angular misalignment between the leadscrew or ball screw and carriage rails.

• The inner surface of the inner ring has the lead nut thread or contains a ball screw nut
• The axial load is carried by the spherical surfaces
• The axles react the torque of the leadscrew and nut pt ball screw and nut
• The complete Punk® Nut assembly incorporates simple sliding mechanisms
• The travel required for linear slides is determined as a trigonometric function of the required angle of misalignment and the length of the leadscrew traversed

The Punk® Nut's unique self-aligning capability maximizes a systems:

• Reliability
• Efficiency
• Longevity
• And reduces installation time and costs

THE PUNK® NUT IN ACTION

Prototyping and testing in progress. Punk® are seeking to licence PunkNut technology for commercial development.
