Compression
latch from
EMKA
EMKA has developed an IP69K
compression latch in stainless
steel with visual status indication
to suit railway and other special
vehicle applications. This allows for
distanced observation of the lock
status – whether the lock is open or
closed – by virtue of a cover which is
linked to the lock. If the lock is open
then the cover is held open. Due to
its compact design and high weather
resistance the latch can be used in
many outdoor areas, such as wind
power plants, tunnel construction,
traffi c facilities and rail vehicles.
The lid of the new EMKA
compression lock is spring-mounted
and snaps shut automatically only
when closed. If the lock is turned by
25 degrees or more, the lid remains
open at an angle of 90 degrees. A
clearly visible opening indicator then
appears on the inside of the lid: a red
area with the EMKA logo. On trains,
for example, railway personnel can
see from a distance as soon as a door
or fl ap is not completely closed.
Major features include resistance
to shaking and vibration, thus
preventing unintentional opening
of the lock, also the lock complies
with protection class IP69K and fi re
protection regulations. Other features
include automatic fl ap closure with
seal on the lock to protect from
damage to the door.

CYCLOIDAL GEARBOXES FOR BONDING
Nabtesco cycloidal gearboxes
enable fast acceleration and
braking, in addition to highprecision
positioning with
backlash of less than one
arcminute.
A reliable and durable bond
depends not only on the choice
of the right adhesive and optimal
composition of the materials to
be joined, but especially on fast
and precise application of the
adhesive bead. Cycloidal gears
from Nabtesco enable perfect
bonded seams with pin-point
positioning, even at high speeds
and accelerations.
The cycloidal design makes
Nabtesco gearboxes very
precise, dynamic and durable.
They feature high torque
capacity, tremendous shock
load resistance (up to 500 % of
the rated torque), and minimum
backlash throughout the entire
life cycle (hysteresis loss 0.5 to
max. 1 arcmin). The low-wear
design ensures a long life and
smooth operation. The large,
integrated angular contact ball
bearings absorb high forces and
moments, and also extend the
service life. Cycloidal gearboxes
are also extremely compact,
which facilitates integration in
applications with limited space.
Whether in the automotive
industry, medical technology
or mechanical engineering:
The high positioning accuracy
and repeatability of cycloidal
gears enable precisely
controlled motions and pin-point
positioning. This is benefi cial
to the systems that apply the
adhesive and also the devices
that align the workpieces. The
use of Nabtesco gearboxes
guarantees maximum precision,
optimal product quality and
stable processes. They make
it possible to bring automated
bonding processes in industrial
production and assembly to a
new level.
