Drive systems with maximum power density With the ASCA servo screw, a genuine alternative now exists for applications which until now have been dependent on hydraulic drives. The basis is the technology of the PWG planetary roller screw. The ASCA servo screw is the technological basis of the SERAC® electric cylinders. Ortlieb Präzisionssysteme GmbH & Co.

ASCA servo screw SERAC® electric cylinders The ASCA servo screw combines the functions of a planetary gear unit with those of a screw. The merging of these two functions leads to a considerable reduction in the space and weight of a drive axis. These fully redesigned servo linear drives utilize the many benefits of the ASCA servo screw. A typical example of the many advantages of the SERAC® electric cylinders is their high dynamics. They are increasingly replacing previous hydraulic solutions in many applications. SERAC® LH100, XH12, KH30 und Servoregler ServoOne SERAC® XHM This screw unit fits...

ASCA servo screw – unique power density for automation The ASCA servo screw is based on the PWG planetary roller screw design principle. This new screw technology converts the rotary motion of a motor directly into linear motion. The dimensions of the ASCA servo screw can be extremely compact in form considering the force achieved. Because the reduction of a planetary gear unit is part of its functionality, the motor connection can be made directly without additional gears. With its compact size and the potential for reaching very high forces and rapid motion with small motors, the ASCA servo...

Drive technology from space travel … Development background The German Aerospace Center (DLR) developed the first remote-controlled robot for the D2 mission (1993). Brilliant design is one thing, but turning it into an industrial-scale product that works reliably in all situations is quite another. The problem of meeting the strict weight limit while generating the required force could not be solved with conventional screw drives. Because of these conflicting requirements, the DLR decided to look for a completely new approach. The project for this solution led to the development of the PWG planetary...

PWG Planetary roller screw Power transmission can be through the screw shaft or the screw nut. The connection between nut and screw is formed by several rotating planetary rollers. The transmission of the drive torque is by frictional locking. This causes low slip – which is not to be confused with backlash. The planetary rollers with their circumferential drive grooves emulate the screw thread according to their various positions in the planet carrier. As they orbit the screw as they spin, the screw is driven axially according to the direction of rotation. The large number of contact surfaces...

Planetary rollers Guide grooves Drive grooves Planetary bearings Screw shaft Planet carrier Efficiency curve [%] The diagram shows the driving torque required to generate a specific force (without allowing for the screw bearing). The diagram shows the efficiency curve of an ASCA servo screw with 1 mm and 2 mm lead. Example: At 2 mm lead, torque of only 3.4 Nm is needed to generate 10 kN. At 1 mm lead this is reduced to 1.9 Nm. It is clear that very high efficiency levels can be obtained even at small leads. Due to the preloading of the planetary rollers, the efficiency is relatively low in the...

ASCA servo screw – lead from 1 mm High travel speeds High translation rates High efficiency High stability and high load capacity with minimal volume! The combination of the “screw” and “planetary gear” principles gives great variability and optimization of the design. Under this principle an electric cylinder with an ASCA servo screw does not generally need an additional gear unit. The specific advantages of this innovative construction include the ability to use a lead of only 1 mm without any problem. The result is very high translation rates and efficiency levels of up to 90 % are achieved...
