Drive systems for solar power systems: Due to their fixed south orientation, the solar irradiation angle of common solar systems is rather unfavourable in the mornings and the evenings: More than 35 % of the daily energy from solar power is lost.
To solve this problem, the solar module is automatically adjusted to the position of the sun in direction of both movement axes.
GFC AntriebsSysteme GmbH has developed special slewing gear units which provide the required high torque range.
From the development of application-specific drives and gear units to the serial production of the latter – with GFC, you can get everything from a single source. Before being shipped to the customer, the drives and gear units are measured and tested on our own test benches.

The new HFUC Series component sets are a result of the continuous development of Harmonic Drive precision reduction gearing. In comparison with standard gears, the new HFUC series features a shortened Flexspline, which results in an important reduction of the axial length. The high performance IH tooth profile provides significantly increased torque capacity compared to gears incorporating the traditional involute gear tooth profile.
Advantages:
- High torque capacity
- Excellent positioning accuracy and repeatability
- Compact design
- High single stage ratios
- High torsional stiffness
- Zero backlash
- High efficiency
- Easy installation and assembly

For rack & pinion applications requiring ultra-precise positioning and repeatability, the system backlash can be eliminated by using two pinions - one to drive the axis and one to "preload" the axis to remove the backlash.
The simplest zero-backlash rack & pinion drive utilizes a split-pinion. A split-pinion consists of two pinion halves and an axial spring pack. The pinions halves mesh with opposite tooth flanks on the same rack, eliminating the backlash. The axial spring pack is used to preload the rack & pinions to insure that no backlash develops during the operating cycle.
The split-pinion shafts mount directly into our Servo Reducers and are fixed in place by means of a compression coupling. This provides rigid support and tight integration of the split-pinion shaft into the reducer. The end result is a compact and ultra-precise positioning axis drive.
These drives are perfect for precision positioning applications, such as traveling gantries and columns, milling machines, and material feel axis drives. Two reducers/motors can also be used to eliminate the axis backlash by electrical preload. For more information on this solution, please consult the factory.

The new benchmark for electrical preload on demanding machine tool applications!
KRPX is the new version of REDEX ANDANTEX rack & pinion high-tech planetary reducers, offering cost effective, easy to implement and high performing solutions for moving column or gantry machine types as well as many other applications.
The KRPX housing is made of high quality spheroidal graphite cast iron. Its structure has been optimised with FEM analysis methods to avoid deflection during acceleration. Fixation is made by oversized screws to ensure a real still connection with the machine frame allowing the KRPX housings to be considered as an integrated part of the machine main frame.
The output pinions are machined to the same diameter as the shafts, allowing the best possible balance between transmissible torque and rigidity at the rack. In addition, output bearing consists of two preloaded and substantially oversized angular contact roller bearings.
This exclusive design offers exceptional compound stiffness which allows to dramatically decrease the radial bending (up to 60% of the overall distortion) and to increase the natural frequencies of the global Racks & Pinions drive systems.
Designed as an association of two high-tech planetary reducers, KRPX allows perfect mounting on both sides of the machine frame and enables true zero backlash when coupled with an electrical preload system.
Available in 3 standard universal sizes (2, 3 and 4) KRPX is very compact, a definitive advantage for helping implementation with respective pinion height not higher than 104, 127 and 148 mm.
With this new and innovative concept, the machine-tools designers can easily expect to exceed market standards with maximum feed capacity up to 105 000 N and stiffness on the rack up to 333 000 N/mm.

Nexen offers an advanced new technology that revolutionizes linear motion. The Roller Pinion System (RPS) provides zero backlash, very high positional accuracy, unlimited length, very high speeds, 99% efficiency, high rigidity, low noise, low maintenance, corrosion resistance, and long life. This opens up
new design possibilities and provides the capability to achieve much higher levels of performance in machine designs.
The RPS's unique design eliminates many of the limitations of current linear drive systems like:
Ball Screws: Limited by critical speed, maximum speed, cumulative error, vibration, thermal expansion, supplemental cooling, noise, low efficiency, maintenance, and life.
Traditional Rack and Pinion: Limited by low accuracy and speed, backlash, tooth fatigue, noise, high cost of dual and split pinion systems, high maintenance, and short life.
Belt Drives: Limited by low accuracy, backlash, low load capacity, short lengths, belt stretch, and low rigidity.
Linear Motors: Limited by low load capacity, high cost, strong magnetic fields, and liquid cooling.

Dedicated to racks & pinions drive applications, the KRP+ design is based either on the use of one single unit or on the association of two top quality planetary reducers, mounted in parallel on the machine main frame.
When used as a SingleDRIVE, the KRP+ gives the benefit of an ultra high stiffness feed gearbox, dedicated to high performances rack & pinions drive systems.
When choosing the mechanical preload solution, the KRP+ become a DualDRIVE unit, which achieve the true backlash free feature by torsionally winding one pinion against the other through the rack.
Immediate benefits are to need only one motor, and to dramatically simplify the motor control.
When choosing the Electrical preload solution, the KRP+ is used as a TwinDRIVE unit, where the backlash is cancelled by the opposite torque balance between the two pinions, according with the two motors and drives remote control.
