dryspin® thread geometry

Smooth operation, less vibration - THE alternative to trapezoidal threads

What does lead screw technology mean and what do i understand by it?
Lead screw technology is a part of drive technology and, roughly speaking, describes the repetitive conversion of a rotary movement into a translatory movement within regular cycles. The dryspin® lead screw technology patented in 2014 by the dryspin® lead screw technology development team. Particular emphasis was placed on increasing service life and improving efficiency. The dryspin® product portfolio includes high-helix lead screws made of stainless steel or aluminium and the matching lead screw nuts made of igus® high-performance polymers. They are available from 1mm to 100mm pitch. The dryspin® thread geometry is an extension of conventional thread technologies such as metric and trapezoidal threads. In contrast to conventional thread geometries, the dryspin® lead screw technology is superior with numerous advantages

Let's take a closer look at these:
In contrast to a metric or trapezoidal thread, the high helix thread has a higher pitch. Thus, a significantly increased linear feed is carried out with one revolution of the lead screw. dryspin® offers better efficiency thanks to the specifications and geometries tailored to the plastic nut and lead screw. Efficiencies of up to 82% and a longer service life are achieved compared to metal lead screw drives. In combination with an igus® lead screw nut, clean and dry operation is possible, without dust and dirt getting stuck.

We tested it!
Our dryspin® lead screw geometry is an excellent alternative to conventional trapezoidal threads. The specifications and geometries of our dryspin® lead screw technology, which are tailored to the iglidur® plastic nut and lead screw, guarantee the well-known advantages: tighter manufacturing tolerances, rounded teeth geometry, optimised flank angle and the asymmetry ideal for plastic nuts compared to DIN 103. Our dimensions are suitable for 1:1 replacement: DS10x2, DS10x3, DS12x3, DS14x4 and DS18x4.

Tighter manufacturing tolerances - improvement by a factor of 3
Trapezoidal threads according to DIN103 (TR18x4) are tolerated with up to -0.3mm on the outside diameter. Excessive radial clearance can lead to noise and vibration. Our dryspin® technology guarantees a maximum tolerance of -0.1mm with the same diameter and identical pitch. We improve the outer diameter tolerance by a factor of three and thus optimise smooth operation and precision, especially at high speeds.

Quiet and vibration-free operation and higher speeds thanks to the rounded tooth flanks of the dryspin® thread geometry
Due to the rounded tooth flanks and tighter manufacturing tolerances of the dryspin® thread geometry, the possible noise-causing contact surface between the lead screw nut and the lead screw is reduced. This is due to the fact that the greater the contact of two surfaces moving against one another, the more vibrations are transmitted, which can be perceived as a rattle or squeak. This means that higher travel speeds can be achieved without causing the corresponding noise.

Up to 30% longer service life - due to thread asymmetry
Due to larger gaps between the individual dryspin® thread pitches, the thread ideally adapts to the specifications of the lubrication-free igus® high-performance polymers. The proportion of the tribologically optimised polymer in the thread turns can be enhanced by a factor of 1.3. More wear-resistant material and higher levels of efficiency are crucial for a service life that is up to 5 times longer compared to standard thread geometries.
