Mount the gearbox so that the identification plate can still be read.
The specified screw sizes and tightening torques can be found in Chapter 10.2 "Specifications
for mounting to a machine".
If your gearbox is equipped with a liquid-cooled adapter plate, the separate manual "Cooled
adapter plate" (doc. no. 2022–D063351) applies for this. The manual will be provided by our
Sales / Customer Service department on request. Please always provide the serial number.
WITTENSTEIN alpha GmbH
offers corresponding mounting kits for gearboxes in
Hygienic
Design
. The separate instructions "Hygienic Design Instruction Sheet, Mounting Kit" (Doc. no.
2022–D062618) are valid for this. The manual will be provided by our Sales / Customer Service
department on request. Please always provide the serial number.
5.4.1 Mounting with through-holes
5.4.2 Mounting with slotted holes
Use only the washers included with the delivery for fastening the gearbox to the machine (see
Chapter 10.2 "Specifications for mounting to a machine").
If your gearbox is equipped with reverse centering for motor-
side installation [M] on a machine, you will find more
information in the separate manual "Reverse centering device
for motor-side installation" (doc. no. 2022–D063062). The
manual will be provided by our Sales / Customer Service
department on request. Please always provide the serial
number.
We recommend doing without washers as long as the
material of the screw surface features sufficient interface
pressure.
Fasten the gearbox on the machine with the fastening screws
through the through-holes [M].
The gearbox can be optionally equipped with an output pinion
[P
1
]. The gearing backlash between output pinion and toothed
rack/counter-wheel can be adjusted using the slotted holes [M]
and the lateral guides. An additional adjustment mechanism is no
longer necessary.
Detailed information on the design of the gearbox interface is
available on request.
For the proper setting of the gearing backlash, you will find
further information in the "alpha rack and pinion system"
manual (doc. no. 2022–D001333). The manual will be provided
by our Sales / Customer Service department on request.
Please always provide the serial number.
Operating the gearbox without a motor (e.g. using a hand wheel) is
permitted for setting / aligning the output pinion on the toothed rack.
When doing so, ensure
never
to tilt / bend the clamping hub.
