dryspin® lead screw technology
in the rear bench seat adjustment
Request dryspin® sample here

Technical data:


What was needed: 
A lead screw drive in the vehicle interior for adjusting the rear seat

Requirements: 
Noise minimisation, smooth, vibration-free operation, corrosion-free, low fogging, high load capacity, lightweight, low coefficient of friction
Products used: 
Lead screw nut and worm wheel made of iglidur RN293 in special design, dryspin trapezoidal lead screw

Success for the customer:
The tribologically optimised material ensures low drive torques, whereby a smaller actuator can be used. Very short development time, since igus harmonises the lead screw nut and worm wheel. Prototypes made of tribologically optimised material by means of the laser sintering printing method are available within 24 hours.
Rear bench seat adjustment

To the rear bench seat adjustment

The electric rear-seat adjustment system can be found in vehicles in which seating comfort is held to be exceedingly important. The drive is responsible for adjustment of the rear bench seat and is often part of so-called memory seats. Important quality characteristics of the igus® solution include noise minimisation, quiet operation and a low coefficient of sliding friction of the material used. Additional lubrication is not necessary as solid lubricants have been integrated into the polymer.
 
In the development phase and during validation, the lead screw drive was exposed to unusual types of stress in the framework of crash tests. Endurance tests, in which amongst other things, wear and noise generation were tested in the temperature range from -20° to +80°C, were withstood by both the lead screws and the nuts from igus® without maintenance or any failures.

What is the difference between dryspin® lead screw drives and those with standard geometries?

High efficiency and low wear

The patented dryspin high helix thread technology was developed by igus in 2013 and offers numerous advantages compared to conventional high helix threads. Due to the flat thread angle, it converts the exerted power efficiently into a translational movement. With properties and shapes matching the polymer nut and lead screw, dryspin thereby provides an even longer service life and more efficiency for high helix threads. Due to the rounded tooth geometry, the contact area between lead screw and nut is reduced, and the lead systems operate quietly and without vibration under load.
 
The larger spaces between the individual dryspin threads result in a higher share (factor 1.3) of tribologically optimised polymer in the threads. More wear-resistant material and higher levels of efficiency are crucial for a service life that is up to five times longer compared to conventional high helix threads.

Five reasons why dryspin® technology is used in automobiles

With the dryspin lead screw technology, it is easy to design individual lead screw nuts and lead screws exactly according to the wishes of the customer. Our experts will be happy to help you choose the right lead screw drive and will ensure that deliver times are short. The wide choice of materials and complete absence of a need for lubrication or maintenance mean that the lead screw drives can be used in almost any area of the automotive industry. They are ideal for small installation spaces and operate almost silently even when the drive torque is low. Uncomplicated integration into your vehicle or assembly is also an aspect that speaks in favour of the cost-effective alternative to conventional lead screw drives made of metal.
