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

EMERGENCY STOP torque:
If there is a need for the transmission of EMERGENCY STOP situations, it is recommended to use torque
limiters (TL1, TL2 and TL3) in order to protect further drive components and to increase the overall service life.
Models EC2, BC2, BC3 and BCH can briefly transmit 1.5 times the T B of the coupling, provided all the other
instructions are complied with (see T Emer ).
For torque limiters with the "Load holding version" functional system, double load safety is ensured for the TL1 cou-
pling (indirect drives), while an adequate size must be ensured for the TL2 and TL3 models with bellows attachment:

The  alpha bet
Acceleration torque (T 2B )
The acceleration torque T 2B is the
maximum permissible torque that can
briefly be transmitted at the output by
the gearhead after ≤ 1000/h cycles. For
> 1000/h cycles, the ??Shock factor
must be taken into account. T 2B is the
limiting parameter in cyclic operation.
Adapter plate
WITTENSTEIN alpha uses a system of
standardized adapter plates to connect
the motor and the gearhead, making
it possible to mount an WITTENSTEIN
alpha gearhead to any desired motor
without difficulty.
Angular minute
A degree is subdivided into 60 angular
minutes (= 60 arcmin = 60’). In other
words, if the torsional backlash is
specified as 1 arcmin, for example,
the output can be turned 1/60°. The re-
percussions for the actual application
are determined by the arc length:
b = 2 · π · r · α° / 360°. A pinion with a
radius r = 50 mm on a gearhead with
standard torsional backlash j t = 3’ can
be turned b = 0.04 mm.
Axial force (F 2AMax )
In the case of SP + /LP + /SPK + , the axial
force F 2AMax acting on a gearhead runs
parallel to its output shaft. On a TP + ,
the force runs perpendicular to its
output shaft. It may be applied with axi-
al offset via a lever arm y 2 under certain
circumstances, in which case it also
generates a bending moment.
If the axial force exceeds the permissi-
ble catalogue values, additional design
features (e.g. axial bearings) must be
implemented to absorb these forces.
Bushing
If the motor shaft diameter is smaller
than the ??clamping hub, a bushing
is used to compensate the difference
in diameter.
Clamping hub
The clamping hub ensures a frictional
connection between the motor shaft
and gearhead. A ??bushing is used
as the connecting element if the motor
shaft diameter is smaller than that of the
clamping hub.
Continuous operation (S1)
Continuous operation is defined by
the ??duty cycle. If the duty cycle is
greater than 60 % and/or longer than
20 minutes, this qualifies as continuous
operation. ??Operating modes
Cyclic operation (S5)
Cyclic operation is defined via
the ??duty cycle. If the duty cycle
is less than 60 % and shorter than
20 minutes, it qualified as cyclic
operation (??operating modes).

veloped by our company for dimensio-
ning complete drive trains. We can also
provide training to enable you to make
full use of all the possibilities provided
by the software.
Degree of protection (IP)
The various degrees of protection are de-
fined in DIN EN 60529 “Degrees of pro-
tection offered by enclosure (IP code)”.
The IP degree of protection (IP stands
for International Protection) is represen-
ted by two digits. The first digit indicates
the protection against the ingress of
impurities and the second the protection
against the ingress of water.
Duty cycle (ED)
The duty cycle ED is determined by
one cycle. The times for acceleration
(t b ), constant travel if applicable (t c ) and
deceleration (t d ) combined yield the duty
cycle in minutes. The duty cycle is ex-
pressed as a percentage with inclusion
of the pause time t e .
Efficiency (η)
Efficiency [%]  η is the ratio of out-
put power to input power. Power lost
through friction reduces efficiency
to less than 1 or 100 %.
η  = P out / P in = (P in – P lost ) / P in
WITTENSTEIN alpha always measures
the efficiency of a gearhead during ope-
ration at full load (T 2B ). If the input power
or torque are lower, the efficiency rating
is also lower due to the constant no-load
torque. Power losses do not increase as
a result. Speed also has an effect on effi-
ciency, as shown in the example diagram
above.
Emergency stop torque (T 2Not )
The emergency stop torque [Nm] T 2Not
is the maximum permissible torque at
the gearhead output and must not be
reached more than 1000 times during
the life of the gearhead. It must never
be exceeded!

HIGH SPEED (MC)
The HIGH SPEED version of our SP +
gearhead has been specially developed
for applications in continuous operation
at high input speeds, e.g. as found in
the printing and packaging industries.
HIGH TORQUE (MA)
The HIGH TORQUE version of our TP +
gearhead has been specially developed
for applications requiring extremely high
torques and maximum rigidity.
MA = HIGH TORQUE
MC = HIGH SPEED
MF = standard versions of our
WITTENSTEIN alpha servo gearheads
Hysteresis curve
The hysteresis is measured to deter-
mine the torsional rigidity of a gearhead.
The result of this measurement is known
as the hysteresis curve.
If the input shaft is locked, the gearhead
is loaded with a torque that increases
continuously up to T 2B and is then
relieved at the output in both directions.
The torsional angle is plotted against the
torque. This yields a closed curve from
which the ??torsional backlash and
??torsional rigidity can be calculated.
Jerk
Jerk is derived from acceleration and
is defined as the change in acceleration
within a unit of time. The term impact is
used if the acceleration curve changes
abruptly and the jerk is infiniy large.
Lateral force (F R )
Lateral force is the force component
acting at right angles to the output shaft
with the SP + /LP + /SPK + or parallel to
the output flange with the TP + . It acts
perpendicular to the axial force and can
assume an axial distance of x 2 in relation
to the shaft nut with the SP + /LP + ) or
shaft flange with the TP + , which acts as
a lever arm. The lateral force produces
a bending moment (see also axial force).
Mass moment of inertia (J)
The mass moment of inertia J is a
measurement of the effort applied by an
object to maintain its momentary condi-
tion (at rest or moving).
Mesh frequency (f z )
The mesh frequency may cause
problems regarding vibrations in an
application, especially if the excitation
frequency corresponds to the intrinsic
frequency of the application.
The mesh frequency can be calculated
for all SP + , TP + , LP + and alphira ? gear-
heads using the formula f Z = 1,8 · n 2 [rpm]
and is therefore independent of the ratio
if the output speed is the same.
If it does indeed become problematic,
the intrinsic frequency of the system
can be changed or another gearhead
(e.g. hypoid gearhead) with a different
mesh frequency can be selected.
NSF symbol
Lubricants certified as grade H1 by
the NSF (NSF = National Sanitation
Foundation) can be used in the food
sector where occasional unavoidable
contact with food cannot be excluded.

Glossary
No load running torque (T 012 )
The no load running torque T 012 is
the torque which must be applied
to a gearhead in order to overcome the
internal friction; it is therefore consi-
dered lost torque. The values specified
in the catalog are calculated by
WITTENSTEIN alpha at a speed of
n 1 = 3000 rpm and an ambient tempera-
ture of 20 °C.
Nominal torque (T 2N )
The nominal torque [Nm] T 2N is the torque
continuously transmitted by a gearhead
over a long period of time, i.e. in ??conti-
nuous operation (without wear).
Operating modes
(continuous operation S1 and
cyclic operation S5)
When selecting a gearhead, it is important
to consider whether the motion profile is
characterized by frequent acceleration and
deceleration phases in cyclic operation
(S5) as well as pauses, or whether it is
designed for continuous operation (S1),
i.e. with long phases of constant motion.
Operating noise (L PA )
Low noise level L PA is a factor of growing
importance for environmental and health
reasons. WITTENSTEIN alpha has suc-
ceeded in reducing the noise of the new
SP + gearheads by another 6 dB(A) over
the former SP units (i.e. sound reduced
to one quarter). Noise levels are now
currently 64 - 70 dB(A) depending on
the size of the gearhead.
The gear ratio and speed both affect
the noise level. The relationships are de-
monstrated in the following trend graphs.
As a general rule: A higher speed
means a higher noise level, while
a higher ratio means a lower noise level.
The values specified in our catalog
relate to gearheads with the ratio
i = 10/100 at a speed of n = 3000 rpm.
Positioning accuracy
The positioning accuracy is determined
by the angular deviation from a setpoint
and equals the sum of the torsional
angles due to load ??(torsional rigidity
and torsional backlash) and kinetics
??(synchronization error) occurring
simultaneously in practise.
Rate of mass moment
of inertia (λ = Lambda)
The ratio of mass moment of inertia λ is
the ratio of external inertia (application
side) to internal inertia (motor and gear-
head side). It is an important parameter
determining the controllability of an
application. Accurate control of dynamic
processes becomes more difficult with
differing mass moments of inertia and
as λ becomes greater. WITTENSTEIN
alpha recommends that a guideline
value of λ < 5 is maintained. A gearhead
reduces the external mass moment of
inertia by a factor of 1/i 2 .
J external reduced to the gear input:
J′ external = J external / i2
Simple applications ≤ 10
Dynamic applications ≤ 5
Highlydynamic applications ≤ 1
Ratio (i)
The gear ratio i indicates the factor by
which the gearhead transforms the three
relevant parameters of motion (speed,
torque and mass moment of inertia).
The factor is a result of the geometry of
the gearing elements (Example: i = 10).
Safety notice
If your application has to meet special
safety requirements (e.g. vertical axes,
tensioned drives), we recommend using
exclusively our alpheno ? , RP + , TP + and
TP + HIGH TORQUE products or contact
WITTENSTEIN alpha for advice.
Shock factor (f s )
The maximum permissible acceleration
torque during cyclic operation specified
in the catalog applies for a cycle rate less
than 1000/h. Higher cycle rates com-
bined with short acceleration times can
cause vibrations in the drive train. Use
the shock factor f s to include the resulting
excess torque values in calculations.
The shock factor f s can be determined
with reference to the curve. This calcula-
ted value is multiplied by the actual ac-
celeration torque T 2b and then compared
with the maximum permissible accelera-
tion torque T 2B . (T 2b · f s = T 2b, fs < T 2B )
Speed (n)
Two speeds are of relevance when
dimensioning a gearhead: the maximum
speed and the nominal speed at the
input. The maximum permissible speed
n 1Max must not be exceeded because
it serves as the basis for dimensioning

The housing temperature limits the
nominal speed, which must not ex-
ceed 90 °C. The nominal input speed
specified in the catalogue applies to
an ambient temperature of 20 °C. As
can be seen in the diagram below,
the temperature limit is reached more
quickly in the presence of an ele-
vated outside temperature. In other
words, the nominal input speed must
be reduced if the ambient tempera-
ture is high. The values applicable
to your gearhead are available from
WITTENSTEIN alpha on request.
Synchronization error
The synchronization error is equal
to the variations in speed measured
between the input and output during
one revolution of the output shaft. The
error is caused by manufacturing to-
lerances and results in minute angular
deviations and fluctuations in ratio.
T 2Max
T 2Max means the maximum torque
which can be transmitted by the gear-
box.
This value can be chosen for applica-
tions that can accept a slight increase
in backlash over time.
T 2Servo
T 2Servo is a special value for preci-
sion applications in which a mini-
mum backlash must be guaran-
teed over the life of the gearbox.
The increase in backlash seen in
other worm gears is less due to the
optimized hollow flank teeth.

and their respective points of appli-
cation in relation to the inner radial
bearing on the output side.

lever arm and force. M = F · l
Torsional backlash (j t )
Torsional backlash j t is the maximum
angle of torsion of the output shaft
in relation to the input. Torsional
backlash is measured with the input
shaft locked.
The output is then loaded with a defined
test torque in order to overcome the in-
ternal gearhead friction. The main factor
affecting torsional backlash is the face
clearance between the gear teeth. The
??Refer to this term for further details.
Backlash
low torsional backlash of WITTENSTEIN
alpha gearheads is due to their high
manufacturing accuracy and the specific
combination of gear wheels.
Torsional rigidity (C t21 )
Torsional rigidity [Nm/arcmin] C t21 is
defined as the quotient of applied
torque and generated torsion angle
(C t21 = ?T/?φ). It consequently shows
the torque required to turn the output
shaft by one angular minute. The tor-
sional rigidity can be determined from
the ??hysteresis curve. Only the
area between 50 % and 100 % of T 2B
is considered for because this area of
the curve profile can be considered
linear.
Torsional rigidity C , Torsion angle Φ
Reduce all torsional rigidities to the
output:
C (n),output = C (n),input * i2

gearbox always relates to the output.
