2 Safety
These instructions, especially the safety instructions and the rules and regulations valid for the
operating site, must be observed by all persons working with the gearhead.
In addition to the safety specifications mentioned in this operating manual, the general and also the
local regulations on the prevention of accidents (for instance, personal safety equipment) and on
environmental protection should be observed.
2.1 EC – Machinery directive
The gearhead is considered a "machine component" and is therefore not subject to the EC
Machinery Directive 2006/42/EC.
Operation is prohibited within the area of validity of the EC directive until it has been determined
that the machine in which this gearhead is installed corresponds to the regulations within this
directive.
2.2 Dangers
The gearhead has been constructed according to current technological standards and accepted
safety regulations.
To avoid danger to the operator or damage to the machine, the gearhead may be put to use only
for its intended usage (see chapter 2.4 "Intended use") and in a technically flawless and safe state.
zBe informed of the general safety instructions before beginning work. (see Chapter 2.7
"General safety instructions").
2.3 Personnel
Only persons who have read and understood these instructions may carry out work on the
gearhead.
2.4 Intended use
The gearhead serves to convert torques and speeds. It is built for industrial applications that do not
fall under article 2 of the directive 2002/95/EU (usage restriction of certain dangerous materials on
electro and electronic equipment).
The gearhead is specified for installment on motors that:
- correspond to the design B5 (for any divergences, please consult our Customer Service
Department [technical customer service])
- show a radial and axial runout tolerance of at least “N” according to DIN 42955 and
- have a smooth shaft
2.5 Reasonably predictable misuse
Any usage that exceeds the maximum permitted speeds, torques and temperature is considered a
misuse and is therefore prohibited.
2.6 Guarantee and liability
Guarantee and liability claims are excluded for personal injury and material damage in case of
- Ignoring the information on transport and storage
- Improper use (misuse)
- Improper or neglected maintenance and repair
- Improper assembly / disassembly or improper operation
- Operation of the gearhead when safety devices and equipment are defective
- Operation of the gearhead without lubricant
- Operation of a heavily soiled gearhead
- Modifications or reconstructions that have been carried out without the approval of
WITTENSTEIN alpha GmbH

2.7 General safety instructions
Objects flung out by rotating components can cause serious injuries.
zRemove objects and tools from the gearhead before putting it into
operation.
Rotating components on the gearhead can pull in parts of the body
and cause serious injuries and even death.
zKeep a sufficient distance to rotating machinery while the gearhead is
running.
zSecure the machine against restarting and unintentional movements
during assembly maintenance work.
Hot gearhead housing can cause serious burns.
zTouch the gearhead housing only when wearing protective gloves or
after the gearhead has been at standstill for some time.
Loose or overloaded screw connections can damage the gearhead.
zUse a calibrated torque wrench to tighten and check all screw
connections for which a tightening torque has been specified.
Solvents and lubricants can pollute soil and water.
zUse and dispose of cleaning solvents as well as lubricants appropriately.

3 Description of the gearhead
The gearhead is a single- or multistage, low-backlash planetary gearhead, which is manufactured
as standard in the following versions:
3.1 Overview of the gearhead components
"M" (motor-mounted gearhead)
Motor centering of the motor-mounted gearhead is performed:
- up to gearhead size SP+100 and a motor shaft diameter of 28 mm of
by the clamping hub (plug receptacle or coupling)
- from gearhead size SP+140 and a motor shaft diameter of >28 mm
by the centering collar of the motor
A radial distortion of the motor is avoided.
Adaptation to various motors is done by an adapter plate and a bushing.
The output shaft bearing is designed to withstand high tilting moments
and axial forces.
The gearhead can be optionally constructed with a coupling to
compensate for thermal linear expansion.
"S" (self-contained gearhead)
The self-contained gearhead is based on the motor-mounted gearhead
and additional mounting parts, such as drive housing and drive shaft (L).
It is possible to drive the gearhead directly at the drive shaft, for instance,
using a belt pulley.
The drive and output shaft bearing is designed to withstand high tilting
moments and axial forces.

Revision: 03 2022-D033540 en-13
5.4.1 Mounting on the slip-on shaft with shrink disk
The slip-on shaft has a smooth design (without keyway). For the load shaft, we recommend the
tolerance h6 (DIN ISO 286). The material must have a minimum yield stress of 385 N/mm2. The
slip-on shaft is axially secured to the load shaft by means of a shrink disk connection. If you have
ordered a shrink disk, it has already been installed on the slip-on shaft.
zIn case you use another shrink disk, observe the instructions of the manufacturer.
LOnly the exterior surface of the slip-on shaft may be greased in the area of the shrink disk seat.
zSlide the slip-on shaft onto the load shaft by hand, taking into account the minimum clamping
length and the maximum permissible depth.
LFor the minimum clamping length and the maximum permitted depth of the slip-on shaft
see Chapter 9.2 "Specifications on mounting on the gear output side", table "Tbl-15".
Dirt can inhibit transmission of the torque.
zDo not disassemble the shrink disk prior to installation.
zDe-grease the load shaft and the slip-on shaft bore in the area of the
shrink disk seat, leaving no residual traces.
The forces of the shrink disk can deform the slip-on shaft.
zAlways install the load shaft first before tightening the clamping screws
of the shrink disk.
A jamming of the shafts can lead to damage.
zMake sure that the slip-on shaft is aligned with the machine shaft.
zMount the slip-on shaft onto the machine shaft without using force.
zDo not on any account attempt an assembly by hammering or applying
pressure.
zTighten the clamping screws (A) of the shrink disk
evenly distributed in multiple circular passes.
zTighten the individual clamping screws only up to
the maximum permitted tightening torque.
LFor bolt sizes and specified torques see
table "Tbl-8".

zCheck that the front surfaces of the outer and inner rings are aligned. Only then is the correct
braced condition obtained. If this flush alignment is not obtained during bracing, the tolerance
of the machine shaft must be checked.
zCheck twice in a row that the clamping screws (A) have the maximum tightening torque.
LIf you want to install a shrink disk that was supplied separately, read the information at
Chapter 5.4.2 "Installing the shrink disk".
5.4.2 Installing the shrink disk
LThe removed shrink disk does not need to be disassembled and regreased prior to bracing
again. It is only necessary to disassemble and clean the shrink disk when it is dirty.
LThe following lubricants are permissible for relubricating the shrink disk:
zPush the shrink disk onto the slip-on shaft.
LOnly the exterior surface of the slip-on shaft may be greased in the area of the shrink disk seat.
zPlease observe the instructions in Chapter 5.4.1 "Mounting on the slip-on shaft with shrink
disk".
Cleaned shrink disks can have other coefficients of friction. This can
lead to damage during mounting.
zLubricate the inner smooth surfaces of the shrink disk using a solid
lubricant with a coefficient of friction of μ= 0.04.
