From high flexibility to high force: Rack and pinion drives.
With the innovative system concept for rack and pinion drives, STOBER has developed a compact, easy-to-use system with process reliability that is precisely tailored to the application areas of machine tools, automation and robotics.
The special highlights are the very flexible and efficient ZV series and the ZTRS series with a supporting bearing holder – for maximum feed force!
- Highly rigid rack and pinion drives as ready-to-install solutions
- ZV: High flexibility for automation and robotics
- ZR: High speed due to high feed velocities
- ZTR: High performance for demanding drive concepts
- ZTRS: High force for maximum power density
All STOBER gear rack and pinion drives are ready-to-install solutions in a wide variety of combinations – adapted to the different requirements in terms of load capacity and precision.
With the helical toothed ZV series you can choose what you like – the pinion position is either at the shaft end or the shaft shoulder.
This series also has an impressive backlash-free, positive-locking shaft-hub connection.
ZV rack and pinion drives can be attached to P, PE, K, KS or KL gear units.
The ZR series features large, helical pinions with a bolt circle, which allow high feed velocities.
The pinions are mounted without an additional flange, which is one reason for the attractive price-performance ratio.
The very precise and also very high-performance ZTR series features small pinion diameters, high linear rigidity and lower torques.
The pinions with the welded screw flange can be easily mounted and dismounted. The ZTR series is therefore ideal for feed axes of machine tools where the supporting bearing holder is an interfering contour. This means gantry machines, vertical and horizontal lathes or milling and drilling centers.
The rack and pinion drives can be combined with PH and PHV series gear units.
Developed by STOBER, the bolted supporting bearing holder with stiffening ribs on the inner contour makes it possible to use the full gear unit torque in a rack and pinion drive for the first time. As a result, this also optimizes the power density and rigidity. To determine the drive, the relevant variable is no longer the tilting torque, but the torque that is actually required.
ZTRS is ideal for feed axes of machine tools, laser machines and highly dynamic and precise handling systems.
The rack and pinion drives can be combined with the PH, PHQ and PHV series gear units.
