dryspin lead screw technology

Lead screw nuts

Flange lead screw nuts

dryspin flange lead screw nut with spanner flat, high helix thread, JFRM

Lior Olshtein

Due to a flatter thread angle in dryspin® high helix lead screws (similar to a trapezoidal thread), the applied force is efficiently converted into a translational motion. Compared with a steeper thread angle, this means a lower power loss. 
 &nbsp; &nbsp;

Due to the radius tooth design, the contact surface between the lead screw nut and the lead screw is reduced. Therefore the dryspin® lead screw nuts move without vibration and are virtually silent. This is because, 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. The rounded teeth minimise this effect and the thread moves without lubrication. 
 &nbsp; &nbsp;

Due to the larger distances between the individual dryspin® thread turns, the thread ideally matches the properties of the lubrication-free igus® high performance polymers. The proportion of the tribologically optimised polymer in the thread turns can be extended by a factor of 1.3 for all sizes. More wear resistant material and higher levels of efficiency are crucial for up to 5 times longer service life of standard geometries. The larger the lead screw diameter, the stronger the impact of this effect. Backlash can be minimised life-long by the use of dryspin® zero-backlash threaded nuts with integrated spring pretension. 
 &nbsp; &nbsp;

DST 10x25, load 175 N, 540 mm stroke, 125 rpm &nbsp;

Stroke 140 mm, 50 N, lead screw C15 rolled, 450 rpm &nbsp; igus® high performance polymers are used in all drylin® linear and drive units as well as lead screw drives. The lubrication is incorporated into the bearing material, rendering the bearing materials suitable for dry-running conditions, i.g. they are maintenance-free for their entire service life. 
 &nbsp; &nbsp;

Wear-resistant high helix thread 10x50, dryspin® high helix thread / Standard high helix thread, load 36 N, 100 rpm for 50,000/150,000/200,000 cycles &nbsp; drylin® lead screw nuts are made from tribologically optimised materials. Starting in the development phase, the focus is on optimising the friction properties of the drylin® lead screw units, with the objective of attaining the lowest possible wear rates and friction values.
