electrically clamped drives
The closed-loop control clamped drives
enable a machine accuracy * of up to < 5 μm
to be achieved. This is regardless of the
moving force, movement speed or axis
length! Here, maximum precision can only
be achieved through the optimal interac-
tion between the individual components.
Such accuracy is only possible for a sys-
tem supplier such as WITTENSTEIN
alpha GmbH.

Perfect lubrication – for a perfect system
In order to achieve a long service life, our rack and
pinion systems require adequate lubrication. We of-
fer you suitable lubricating pinions, fastening axles,
and lubricators, all adapted perfectly to our systems.
The polyurethane foam lubricating pinion is supplied
with a preset quantity of grease via a lubricator or
central lubricating system. This ensures an optimal
lubricating film on the rack and pinion. In addition
to the supply of lubricant, the lubricating pinion also
ensures cleaning of the open toothing.
Your benefits
· Greatly reduced maintenance costs:
- Replaceable cartridge
- Up to 16 lubrication points can be supplied
with just one lubricator
- Lubricating pinion has a long service life
· Can be fully integrated in the machine control system:
- Direct control
- Different error messages via PLC
· Lubricant quantities can be precisely adjusted
to the application (minimal-quantity lubrication)
· Minimal current required
· Perfectly adapted for the lubrication of rack

The design options will dictate whether the rack or the output pinion should be
lubricated. Lubrication via the output pinion is preferable owing to the better
lubricant distribution.

Lubricant need for Lubrication with PU lubrication pinion
alpha Rack & Pinion System accessory range – Lubrication
Lubricating pinion – general information
Due to the possibility of high moving forces and
dynamics of the drives used, the open toothing of
our rack and pinion drives must be lubricated. We
recommend automatic re-lubrication using our poly-
urethane lubricating pinions.
Re-lubrication with the PU lubricating pinion ensures
that the lubricant is applied to the toothing continu-
ously and automatically. For this purpose, the lubri-
cating pinion, which is adapted to the toothing of
the pinion or rack, engages with the teeth, where it
transfers the lubricant to the toothing torque-free.
The open-cell polyurethane foam ensures an opti-
mal supply of the toothing with lubricant, even over
extremely lengthy periods. The material partially
stores the lubricant and dispenses minute amounts
of it. This ensures that continuous lubrication and
wear through insufficient lubrication is prevented.
In order to ensure full functionality of the lubricating
pinion from the start of operation onwards and to
prevent damage to the drive through dry starting,
it must be pre-lubricated (ideally soak in the grease
used for several hours)!

alpha IQ and torqXis –
integrated sensor technology or modular sensor systems
Understanding processes
Inligent sensor systems
Whether integrated in the gearhead
or as a modular solution, sensors
allow you to measure, diagnose and
assess process parameters directly,
i.e. all mechanical loads processed
by the gearhead can be measured
at the output drive.
Further information is available
on?the Internet at:
www.wittenstein-sensors。。ｃｏｍ
Use of sensors
Cost savings – drive design
Thanks to this innovative technology, it has now be-
come possible to take real values into account dur-
ing drive design. This not only saves costs, but also
enables a compact design.
Controlling the forces in the drive train
Unforeseen failures in the drive train result in enor-
mous costs. The acting load spectra are measured,
analyzed and diagnosed using innovative sensors.
Preventive tool wear warning system
With the aid of sensor technology, conclusions
can be drawn regarding the condition of the driven
tools based on changes in the applied torque or
the lateral force in the drive train.
Enhancing machine availability
Inligent systems continuously monitor the drive
status, allow maintenance measures to be planned
more effectively and shorten the response time for
maintenance deployments to a minimum.
Efficient drive control
Load-dependent process control is made possible
through online calculation of the torque and lateral
force. Innovative sensors used as an active control
element not only improve process quality, but also
help in understanding and improving the process.
Quality verification in the drive train
The top priority is of course to prevent faults.
However, when a fault does arise, it is just as impor-
tant to analyze it as accuray as possible! In many
cases, this can be achieved with the aid of sensor
technology.

Your benefits:
· Compensation for shaft misalignment
· Compley backlash free
· Selectable torsional rigidity/damping
· Compact design
· Extremely simple installation (plug-in)
· Maintenance-free and fatigue endurable
· Ideal for connection to spindle drives,
toothed belt drives and linear modules
Fields of application:
· Machine tools
· Packaging machines
· Automation and handling technology
· Printing presses
· Particularly linear drives
(spindle drives, toothed belt axes)
· Applications in continuous operation
Elastomer couplings ensure precisely manufactured hubs and attachable intermediate elements for maximum true-running accuracy
in the drive train. In addition, torque peaks and vibrations are damped to ensure superior smooth running.
The elastomer insert you select largely determines the characteristics of the entire drive train. Select between 3 versions and thereby
determine the damping characteristics and torsional rigidity you require.

· Minimal maintenance requirements
· Extremely high service life of machine
and components
· TüV certification
*( For suitable switches, see Page 403)
Torque limiters with integrated mechanical switching mechanism combine dynamic and precise transmission with TüV-certified torque
limitation. They therefore protect the drive and machine from overload.

Couplings
Alpha torque limiters are factory adjusted to the specified disengagement torque, which is marked on the coupling.
Thanks to the installed disc springs with special degressive spring characteristics it is also possible to adjust the preset
disengagement torque within the adjustment range.
Adjustment of the disengagement torque can be carried out using a torque adjusting wrench
