drylin® linear axes with lead screw drive are designed for positioning tasks of all kinds. Linear adjustment is with trapezoidal lead screws of different sizes or high helix lead screws that can be set in motion either manually or electrically.
The maximum travel speed is up to 1.6m/min, depending on thread and load. Stroke length is freely selectable for any linear drive system. A plain-bearing-mounted lead screw has a maximum stroke of 1,500mm, a ball-bearing-mounted one 1,000mm.
The drive technology online configurator gives you the right drive technology system after you enter your requirements. You also have the option of requesting or ordering motors and other accessories, such as the motor control system.
The SHT Designer enables you to configure a custom SHT lead screw linear system in just a few steps. You can also configure a custom drive pin (optional). A 3D model of the linear system is created automatically.
The lead screw drive is one of the drive systems of the linear drives. The translational movement of the moving body is generated by a rotating lead screw and transmitted to the lead screw nut. So it is a rotary movement converted into a linear motion. Industrial examples include the lead screw drive for an automatic boot lid of a car, as well as lead screw drives required for opening and closing dome lights, conventional windows or roof windows for natural ventilation.
igus uses self-locking trapezoidal lead screws made of steel and stainless steel for all drylin linear units. Lead screws made of hard-coated aluminium are also available upon request for special applications.
Optional high helix lead screws made of stainless steel are available and configurable for the series of linear modules with lead screw drive (SHT) and linear modules based on drylin W (SLW). These options allow much higher travel speeds and gradients, but have no self-locking.
Shafts made of hard-anodised aluminium belong to the standard range and are the most frequently used version. The reason is a low coefficient of friction and wear and short delivery times. If the linear axes with lead screw drive (SHT) type is used, steel or stainless steel shafts are conceivable in addition to aluminium.
Without the use of external lubricants and also maintenance-free? This applies to all bearing points of the drylin linear units for drive technology. The high-performance polymers are optionally available for applications with high temperatures up to +180°C (iglidur X). If FDA-compliant components are required, iglidur A180 bearing materials will help.
As can already be seen from the car boot lid example above, the electric lead screw drive is becoming increasingly important due to a variety of motorised adjustment options. In electronic drive technology, igus offers suitable linear axes based on lead screw drives that can be operated with both hybrid stepper motors and direct current gear motors. igus linear axes are completely ready for installation and connection. Their operation is clean and dirt-resistant.
In our instructions you will find out which alignment of the electrical connections for e.g. motor, encoder or brake connection is best suited for the lead screw axis.
We define the alignment in degrees (looking at the motor from behind).
